xxviii IBM Virtualization Engine for Tape TS7520: Introduction and Planning Guide
Chapter 1. Introduction
The TS7520 Virtualization Engine is a high-performance, high-capacity open
systems virtual tape product designed to augment the tape backup and restore
process in large tape environments. The TS7520 emulates an IBM 3584 tape library
populated with Linear Tape-Open (LTO) 2, LTO 3, and 3592 tape drives to increase
the speed and reliability of existing third-party backup applications. The TS7520
leverages your existing Fibre Channel SAN to transfer data to and restore data from
disk-based virtual tape at ultra-high speeds.
As in a conventional tape system, TS7520 virtual tape libraries support bar codes
as a mechanism to identify tapes. However, because they are virtual, the TS7520
eliminates the common problem of backup applications being assigned large tapes
and then actually using only a fraction of the total space. With the TS7520, you can
create virtual tape libraries and the system automatically allocates additional space
as needed.
Because you might already have physical tapes that you would like to protect, data
from physical tapes can be imported into your virtual tape system. If you ever need
to recover files from a physical tape, you can use the TS7520 to access those
tapes for immediate recovery. For additional data protection, or to free space in the
TS7520, the data on virtual tapes can be exported to physical tapes. Data can also
be copied to physical tapes using your backup application’s copy function.
The TS7520 is designed to aid in the tape backup and restore process by providing
customers significant operational and throughput efficiencies via tape virtualization,
namely:
v Backup window reduction
v Restore time reduction
v Data sharing and resource virtualization facilitation
v Operational efficiencies and management improvement
v Total cost of ownership reduction
v Capability to allow multiple disparate backup applications to share the same
physical resources
v High availability options
v Improved sharing of tape libraries across applications and servers
v Integrated server, disk, and tape solution for IT Optimization
The TS7520 is a tape virtualization solution for open systems attachment over Fibre
Channel interfaces. With TS7500 version 2 release 1, iSCSI attachment is also
supported. Significant operational efficiencies can be achieved by storing the daily
backup in the TS7520 disk cache. As backup data ages, the older data may be
migrated to physical tape for longer term storage. Since daily backup data is now
written to virtual tape via the disk cache, heavy daily tape drive usage is greatly
reduced. Fewer personnel are typically needed to administer the backup process
when it includes virtual tape.
A TS7520 equipped with one TS7520 Virtualization Engine Server has up to eight
Fibre Channel ports available for host or tape attachment. A TS7520 equipped with
two TS7520 Virtualization Engine Servers has up to sixteen Fibre Channel ports
© Copyright IBM Corp. 2005, 2007 1
available for host or tape attachment. With up to 16 fibre Channel interfaces, a two
node TS7520 can connect up to 8 ports directly to tape SAN. With four nodes, this
number increases to 16.
The TS7520 differs from many other open systems virtual tape products, by
enabling either parallel tape attachment or direct tape attachment. In parallel tape
attachment, physical tape drives or libraries are attached to the host server and
data is transferred from the TS7520 through the host server to physical tape drives
or libraries that are physically attached to the host server. In direct tape attachment,
physical tape drives or libraries are physically attached to the TS7520.
Backup window reduction may be achieved in many installations. Since robotic
movement, tape load/thread, and physical tape search and rewind is eliminated in
virtual tape, the effective utilization of the Fibre Channel interfaces is increased.
That means more tape jobs can be run to virtual tape over a single interface than to
physical tape. If the backup window is reduced, the time allowed for migration to
physical tape is increased, thus potentially reducing the number of physical tape
drives and media needed for longer term backup data storage.
Business continuity is increased providing better restore time objectives. Restore
times are decreased if the data is in the disk cache of the TS7520. With the
TS7500 V2R1, 1024 virtual tape drives, and 128 virtual tape libraries, each backup
server can be allocated their own virtual resources, allowing multiple and disparate
backup applications to use the same physical resources. This provides the potential
for infrastructure simplification. Multiple different tape libraries and tape drives can
be aggregated to one or more TS7520s, centralizing the backup resources and
further reducing the operational cost.
Key features
Key functional features of the TS7520 3954 CV6 are:
v Virtual support of IBM LTO 2, LTO 3 Tape Drives, and 3592 Tape Drives Model

Using the default library configuration
The TS7520 Virtualization Engine comes preconfigured with two virtual 3584
libraries per Virtualization Engine. Each library is comprised of 12 virtual LTO 2 tape
drives and 253 slots. Each library is preconfigured with virtual tape cartridges. The
number of tape cartridges preconfigured is proportional to the total system capacity.
Up to four cards are available for host connection: any combination of fibre channel
(dual ports) or Ethernet (quad ports). A minimum of one card is required for host
connection. Up to two fibre cards (4 ports) can be dedicated to physical tape
connection. Up to two ethernet cards (8 ports) may be used for network replication
connections.
The default libraries are accessible when the TS7520 is powered up. You can
immediately start using these libraries without any additional configuration
necessary through the VE Console. However the VE Console provides information
that is helpful in creating the necessary zones when connecting to a storage area
network (SAN).
If you are not connecting the TS7520 to a SAN, you can directly cable your backup
server or host to one of the target ports and perform a device discovery (the same
as you would a physical library). From the rear of the TS7520 the default target
ports are PCI Slot 3 Port 1 or PCI Slot 4 Port 1 if 2 fibre channel cards are added
to the default 2 which are required.. Each port is assigned to one of the default
libraries.
If you are connecting to a SAN, you will need to zone the target world wide port
name (WWPN) of the TS7520 with the WWPN of your backup server or host.
12 IBM Virtualization Engine for Tape TS7520: Introduction and Planning Guide
For additional information about the default library configuration, see “Default library
configuration” on page 57. You can also refer to the IBM Virtualization Engine for
Tape TS7520 User’s Guide.
Data management and advanced features
The TS7520 Virtualization Engine is designed with the following data management
and advanced features that allow you to securely process and access your data
according to your business needs even if it is 24 hours a day and 7 days a week.
RAID
Redundant array of independent disks (RAID) is a method of configuring multiple
disk drives in a storage subsystem for high availability and high performance. The
collection of two or more disk drives presents the image of a single disk drive to the
system. In the event of a single device failure, data can be read or regenerated
from the other disk drives in the array.
The TS7520 supports groups of disk drive modules (DDMs) in RAID 5. RAID 5 is a
method of spreading volume data plus data parity across multiple disk drives. RAID
5 increases performance by supporting concurrent accesses to the multiple DDMs
within each logical volume. Multiple spare drives are allocated in the TS7520 cache
to increase the redundancy.
In the case of a DDM failure, the TS7520 Cache Controller will automatically
configure a spare to take over the role of the failed drive. Data and parity will be
rebuilt on the “spared in” drive. Upon replacement of the failed drive with a new
one, the TS7520 Cache Controller will “spare out” the previous spare drive to a
backup (or spare) role again.
Failover/failback
TS7520 Virtualization Engine’s failover/failback option provides high availability for
TS7520 Virtualization Engine operations by eliminating the down time that can
occur should a TS7520 Virtualization Engine Server (software or hardware) fail.
In the TS7520 Virtualization Engine failover design, a TS7520 Virtualization Engine
Server is configured to monitor another TS7520 Virtualization Engine Server. In the
event that the server being monitored fails to fulfill its responsibilities to the SAN
Clients it is serving, the monitoring server will take over its resources.
TS7520 Virtualization Engine uses a unique monitoring system to ensure the health
of the TS7520 Virtualization Engine Servers. This system includes a self-monitor
and an intelligent heartbeat monitor.
The self-monitor is part of all TS7520 Virtualization Engine Servers, not just the
servers configured for failover and provides continuous health status of the server. It
is part of the process that provides operational status to any interested and
authorized parties, including the Console and supported network management
applications through SNMP. The self-monitor checks the TS7520 Virtualization
Engine processes and connectivity to the server’s storage devices.
In a failover configuration, TS7520 Virtualization Engine’s intelligent heartbeat
monitor continuously monitors the other server through the same network path that
the server uses to serve its own clients.
Chapter 1. Introduction 13
Failover requirements
Follow these requirements when setting up a failover configuration:
v You must have two 3954 CV6 in a single 3952 F05 frame
– Failover to another CV6 in a different F05 frame is not possible, because both
SV6 must have access to the same disks.
v Static IP addresses must be used
There are two IP addresses needed for each adapter. One IP address is for
management, which you use for your VE Console, called Server IP address. And
one IP address is used for heartbeat connection, called Service IP address
– Two IP addresses for first heartbeat (service) connection and management
(sever) connection on each node for eth1
– Two IP address for second heartbeat connection and management connection
on each node for eth1- must be on different subnet than the first heartbeat
connection
v A physical tape library, if used, must be connected to both CV6
v No replication between the both TS7520 is allowed.
For additional information about the Failover option, see the IBM Virtualization
Engine for Tape TS7520 User Guide.
Network replication
Replication protects the data on a virtual tape by maintaining a remote copy of the
virtual tape on another TS7520 Virtualization Engine Server (called the target
server) over the IP network.
At prescribed intervals, when the tape is not in use, changed data from the primary
virtual tape is transmitted to the replica resource on the target server so that they
are synchronized. The target server is usually located at a remote location. Under
normal operation, backup clients do not have access to the replica resource on the
target server.
If a disaster occurs and the replica is needed, the administrator can promote the
replica to become the primary virtual tape so that clients can access it.
For additional information about the Replication option, see the IBM Virtualization
Engine for Tape TS7520 User Guide.
Physical Copy on Export
Physical Copy on Export exports data to physical tapes whenever a virtual tape is
exported from a virtual library (such as from a backup application or other utility). In
order to use this feature, the physical tape library must support barcodes. When the
TS7520 attempts to export to a physical tape it must find a matching barcode in a
physical library (you do not need to specify which physical library). If you use Auto
Archive, determine if you want the virtual tape copied (retained) or moved
(removed) after the data is transferred. If you select to move the virtual tape,
indicate how long to wait before deleting it. Also, indicate if you want to export your
physical tapes after archiving.
For additional information about Auto Archive, see the IBM Virtualization Engine for
Tape TS7520 User Guide.
14 IBM Virtualization Engine for Tape TS7520: Introduction and Planning Guide
Network Copy on Export
Network Copy on Export replicates data to another TS7520 server whenever a
virtual tape is exported from a virtual library (such as from a backup application or
other utility). If you use Auto Replication, determine whether you want the virtual
tape copied (retained) or moved (removed) after the data is replicated.
For additional information about Auto Replication, see the IBM Virtualization Engine
for Tape TS7520 User Guide.
Enhanced tape caching
The Enhanced Caching option enhances the functionality of TS7520 by acting as a
cache to a physical tape library, providing transparent access to data regardless of
its location. With the Enhanced caching option, tapes will always appear to be
inside virtual libraries and will be visible to the backup application regardless of
whether the data is actually on disk or tape. This means that the backup application
will always have direct access to data regardless of whether the data is on disk or
on physical tape.
4-way node support
This permits the sharing of all virtual media among all four potential CV6 servers.
Any virtual library’s medium changer and media will be available to any CV6
(subject to the user-specified definitions). CV6s will maintain their own virtual drives
and failover will only be done to a preassigned CV6 housed in the same rack. In
addition, implementation of the virtual pass-through function which permits volumes
to be moved between CV6s via a shared virtual shelf or vault will be performed.
NDMP
The NDMP backup support option allows backup applications and NAS devices to
perform backup and restore using the NDMP version 4 protocol over an IP network.
With this enabled the TS7520 acts as an NDMP server, centralizing management
while eliminating locally attached tape devices from each NAS device. When a
backup occurs, data is moved from a NAS device directly to the virtual library.
Note: This option is not needed when presenting a virtual tape library over FC to a
NAS filer as a replacement for a physical library.
Remote copy
You can copy the contents of a single tape to a remote target server. Because the
Remote Copy feature replicates the full tape rather than appending to an existing
virtual tape, you can only copy a tape if there is no virtual tape on the remote target
server with the same barcode. Therefore, if you have copied this tape before, you
must delete the copy from the remote target server before continuing.
For additional information about the Remote Copy feature, see the IBM
Virtualization Engine for Tape TS7520 User Guide.
CPF/DPF
Through a chargeable feature, Control Path Failover and Data Path Failover are
available to provide redundant access to virtual drives contained within virtual
libraries. This works the same as it does in the IBM 3584 library in that it allows the
host to create virtual copies of drives based on different physical paths to the
device. If a physical path between the host and the TS7520 goes down, the
command is retried at the device driver level on an alternate path.
Chapter 1. Introduction 15
Import/export
Because you might already have physical tapes that you would like to protect, data
from physical tapes can be imported into your virtual tape system. If you ever need
to recover files from a physical tape, you can use the TS7520 Virtualization Engine
to access those tapes for immediate recovery.
The import function allows you to:
v Copy the contents of a physical tape to a virtual tape
v Directly access a physical tape without copying the entire tape
v Recycle a physical tape
For additional data protection, the data on virtual tapes can be exported to physical
tapes for long-term data archiving. Data can also be copied to physical tapes using
your backup application’s copy function.
When you export, TS7520 Virtualization Engine copies/moves the contents of the
virtual tape to a physical tape. Because some third-party backup applications alter
what they write to the tape depending on the type of cartridge used, TS7520
Virtualization Engine only exports tapes to like media. You cannot export to a
dissimilar physical tape. Exporting tape to like media will enable the backup
application to accept the tape as valid; from the backup application’s point of view,
there is no difference between the virtual and physical tape.
Note: If you will be importing data from physical tapes into your virtual tape library
or exporting virtual tapes to physical tapes, you must assign your physical
tape libraries/drives to the TS7520 Virtualization Engine.
For additional information about importing and exporting, see the IBM Virtualization
Engine for Tape TS7520 User Guide.
TS7520 limitations
The following list describes known limitations for the TS7520 Virtualization Engine.
v The TS7520 provides emulations of LTO2, LTO3, and 3592 J1A and E05 drives,
TS3310 (3576 Models L5B and E9U), TS3200 (3573 Model L4U) and TS3100
(3573 Model L2U)- with LTO3 drives; 3583 (Models L18, L36, and L72) - with
LTO3 drives; 3584 with 3592 (J1A or E05 drives), that are sufficient for
successful operation and behavior with the listed supported ISV applications
running on server platforms with fabric components specified in the following IBM
support Web site:
www.ibm.com/storage/support/
The Virtual libraries/drives will include: 3584 (Model L22 for 3592 J1A and E05
drives and L32 for LTO2 and LTO3 drives ); TS3310 (3576 Models L5B and
E9U), TS3200 (3573 Model L4U) and TS3100 (3573 Model L2U) for LTO 3
drives; 3583 (Models L18, L36, and L72) - with LTO3 drives; and Inquiry strings
for “TS7510” and “TS7520”.
IBM claims that the TS7520 provides a sufficient emulation of the specified tape
drive and library interface architecture to support successful operation of listed
supported applications. IBM does not claim that every command of the full native
drive or library architecture is supported. Only those portions necessary to enable
successful operation of the cited ISV applications are supported by IBM.
v While the TS7520 supports failover in the case of a TS7520 Virtualization Engine
Server (3954 CV6) failure and supports multipath redundancy in its internal
16 IBM Virtualization Engine for Tape TS7520: Introduction and Planning Guide
access to the TS7520 Cache Controllers (3955 SV6s) and TS7520 Cache
Modules (3955 SX6s), the failover is not transparent. Depending on the ISV
being used, backup jobs may have to be restarted.
v Any fabric component (switch port or direct host or tape attachment) that is
directly connected to the TS7520 must be loop-protocol-capable.
– Switch ports that attach to the TS7520 must support fabric loop (FL) ports.
(Other switches in the fabric that do not connect to the TS7520 are not
required to support FL ports.)
– Tape drives that attach to the TS7520 directly (and not through a fabric) must
support node loop (NL) port attachment.
v The TS7520 does not currently support FCTAPE link recovery. Some link events
will not be recoverable transparently. Customer tasks may be interrupted,
requiring a restart.
v An import task that encounters a not-ready condition from a physical tape drive
may require user intervention to recognize the stalled task and initiate
cancelation.

Chapter 2. Physical planning specifications for the TS7520
This section provides physical planning and site specifications for the TS7520
Virtualization Engine. Before the TS7520 Virtualization Engine is installed at your
site, verify that your planned installation site meets these requirements, or prepare
the site so that it does meet these requirements. Preparations might involve
meeting area requirements, environmental requirements, and electrical
requirements for TS7520 Virtualization Engine installation, service, and operation.
Site preparation
Use the following information to prepare a location for installation of the system’s
components.
Prepare a floor plan that includes the following information:
v Power outlet locations, types, and ratings
v Frame locations
v Operator and service clearances
v Dimensions of the area containing all system components
Before hardware installation can begin, the local installation planning representative
must verify that all installation planning and preparation is complete. Additional user
responsibilities include planning for the following:
v Cabling and wiring for connections to the host
v Cooling and heating
v Telephone service
v Safety and security
v Fire detection and suppression
v Floors (both raised and non-raised) that meet the operational and structural
requirements necessary for the system components
Calculating space requirements
When you plan the installation location, you must first calculate the total amount of
space that is needed for the TS7520 units, including all service clearances and
weight distribution areas.
Lighting considerations
The 3952 Tape Frame and TS7520 Virtualization Engine are designed for lights-out
operation. No special lighting considerations apply.
Upgrade considerations
When planning for system installation, consider any potential future growth such as
the addition of expansion frames. Consult your IBM representative for current
planning information regarding upgrades to the 3952 Tape Frame and TS7520
Virtualization Engine.
Accommodating cables
Review the following considerations when planning for cabling accommodations:
© Copyright IBM Corp. 2005, 2007 19
v Electrical power cabling should be planned in advance of delivery of the TS7520.
This planning includes cabling for a second source if the dual power option has
been ordered and if independent sources are intended to be used.
v Fibre channel cabling from the TS7520 adapters to the attaching customer
servers or customer switch fabric should be included in the planning, as well as
fibre channel cabling from the TS7520 to any attached physical tape drives and
libraries. In addition, customers should plan for the fibre channel cabling from the
TS7520 base frame to the TS7520 expansion frame (if present).
v Ethernet cabling will be required for attachment of the TS7520 to the operator
console or consoles and to the network for replication and for call-home
reporting. For optimal service, IBM requires that at least one VE Console system
must be installed within 50 feet (15.25 meters) and within line of sight of the
TS7520 3592 Tape Frame.
v Failover configurations require a network connection for the corresponding
Ethernet ports on the two TS7520 Virtualization Engine Servers for mutual
operational state monitoring.
Height requirements
The minimum floor-to-ceiling clearance required for installation of the 3952 F05
Frame is 1.83 m (72 in.), including all installation, operating, and service
clearances. The 3952 F05 Frame is moved on casters and has four leveling pads.
The frame’s nominal height is 1.815 m (71.5 in.) from the bottom of the leveling
pads to the top of the frame. The leveling pads can vary the height of the frame by
up to 30 mm (1.2 in.). The pads are completely raised when the frame is shipped to
allow it to roll on its casters. The shipping height of the frame on its casters is 1.8 m
(70.9 in.).
Dimensions and weights of models
When you are planning the floor and space requirements for your storage units,
consider the dimensions and weights of your configuration components.

Operator and service clearances
Clearances are required around system components for the operator and the
service representative to perform certain tasks. See Table 4 for specific clearance
requirements for each frame type.
Table 4. Operator and Service Clearance Requirements
Component Area Size (Width × Depth) (see note 1)
3952 Tape Frame (see note 2) 644 mm × 1102 mm (25.4 in. × 43.4 in.)
Notes:
1. Size is defined by the depth from the outside of the frame and either the width
of a standalone frame or the length along any frames installed side-by-side. The
width is on a frame-to-frame basis; space required in front or behind each frame
is additive. The access space for individual frames overlaps.
2. Required clearance around the 3952 Tape Frame is listed below:
v Front: 690 mm (27.2 in.)
v Back: 660 mm (26.0 in.)
v Side: 0 mm (0 in.)
Unlike weight distribution areas that are required to handle floor loading, keep in
mind that service clearances of adjacent unrelated storage units can overlap.
Note: The terms service clearance and weight distribution area are often confused
with each other. The service clearance is the area that is required to open
the service covers and to pull out components for servicing. The weight
distribution area is the area that is required to distribute the weight of the
storage unit.
Aisle and door clearances
Two persons should be available to move system components between locations.
The following are the minimum aisle and door dimensions for moving components
from one location to another.

Floor requirements
A 3952 Tape Frame can be installed on a raised or solid floor meeting the minimum
leveling and floor-loading capacity requirements.
Floor level requirements
The leveling pads on the 3952 Tape Frame can be adjusted to compensate for an
uneven floor where the frame is to be installed. The maximum out-of-level condition
is 25.4 mm (1 in.) over the frame’s length and width.
Note: IBM strongly recommends that stringers be installed between all corner
posts. In addition, a post should be placed under the areas where the
frame’s leveling pads sit. As an alternative to placing posts under the leveling
pads, a post may be placed at the midpoint of the stringers in the areas
where the frame sits.
Weight distribution and floor loading
If the 3952 Tape Frame is installed on a raised floor, the raised floor should be
stabilized to prevent a horizontal shift of the raised floor structure. IBM recommends
a floor load rating of at least 341 kg/m2 (70 lb./ft.2). These ratings do not include
additional loading by personnel and equipment traffic.
Security considerations
Controlling access to the 3952 Tape Frame and TS7520 Virtualization Engine is the
user’s responsibility. The system should be installed in a controlled-access area to
prevent unauthorized access to the system’s internal components and to the
TS7520 Virtualization Engine VE Console.
Operating environment requirements
You must meet specific operating environment requirements at all the air intake
locations of your models.
The operating points vary depending on the state of the model. The models can be
in the following states:
v Operating
v Powered off
v In storage
v In transit
Table 5 on page 23 lists the acceptable temperature and humidity ranges in which
the TS7520 Virtualization Engine is designed to operate.

Notes:
1. The nonoperating environment must not exceed the operating environment
limits for longer than 60 days.
2. The storage environment must not exceed the operating environment limits for
longer than 1 year.
3. Substantial deviations from the suggested operating range, in either direction, if
sustained for extended periods of time, will expose the unit to greater risk of
failure from external causes.

3. 10 dB (decibel) = 1 B (bel)
These levels are measured in controlled acoustical environments according to ISO
7779 and are reported in accordance with ISO 9296. The declared sound power
levels indicate an upper limit, below which a large portion of machines operate.
Sound pressure levels in your location might exceed the average 1-meter values
stated because of room reflections and other nearby noise.
Considering safety issues
You must consider various safety issues when you plan your TS7520 series
location.
The following list identifies some of the safety issues you must consider:
v Fire suppression
v Earthquake safety
Providing a fire-suppression system
You are responsible for providing a fire suppression system for your TS7520.
IBM designs and manufactures equipment to internal and external standards that
require certain environments for reliable operation. Because IBM does not test any
equipment for compatibility with fire-suppression systems, IBM does not make
compatibility claims of any kind. IBM does not provide recommendations on
fire-suppression systems.
Consult your insurance underwriter, local fire marshal, or local building inspector
about selecting a fire-suppression system that provides the proper level of coverage
and protection.
Earthquake effects
There is no guarantee against equipment damage as a result of an earthquake.
Many factors influence the stress imposed on system equipment, including:
v Intensity and duration of the earthquake
v Equipment structural strength and durability
v Equipment location within a structure
24 IBM Virtualization Engine for Tape TS7520: Introduction and Planning Guide
v Equipment installation method
v Building type
v Soil conditions
Guarantees of equipment reliability cannot be made for all earthquakes and
conditions. The damaging effects of an earthquake are minimized by appropriate
installation and planning techniques. Significant sliding and rocking of equipment
during an earthquake might directly or indirectly result in damage. The following
steps can help minimize damage:
v Position equipment far enough from walls to prevent or minimize collision.
v Ensure that power and accessory cables are long enough to accommodate
sliding and flexing during an earthquake.
v Ensure that cable clamps or other strain reliefs are secured properly to
equipment.
v Secure several tall units together to form a more stable structure.
v Use a flexible restraint that allows a limited amount of movement, approximately
75 mm to 150 mm (3 in. to 6 in.), to dissipate energy imparted by the
earthquake.

The TS7500 V2R1 software (5697-N65 or 5697-N66) must be ordered and installed
with each TS7520 Virtualization Engine. This software is preloaded on the TS7520
Virtualization Engine Server by specifying the following feature:
v 9302 (Enterprise Edition VE Preload - AAS) -to have the factory install the
5697-N65 program.
v 9303 (Limited Edition VE Preload - AAS) - to have the factory install the
5697-N66 program.
The following other features are available on the TS7520 Virtualization Engine
Server:
v 1682 (Path Failover) - enables automatic control path failover to a
pre-configured redundant path without aborting the current job in progress. It also
provides failover for multiple redundant paths in a SAN environment by
automatically providing error recovery to retry the current operation using an
alternate, pre-configured paths without aborting the current job in progress. This
can provide flexibility in SAN configuration, availability, and management.
v 7420 (Failover/Failback) - enables hardware connections between two installed
TS7520 Virtualization Engines in the same 3952 Tape Frame. Failover/Failback
provides the ability for the host connections and jobs being performed on a
server in a failover pair to be moved to the surviving server of the failover pair in
the event of a server failure.
v 7421 (Network Replication) - enables the TS7520 Virtualization Engine Server
to support the Network Replication function in the TS7500 V2R1 software. If this
feature is installed on one TS7520 Virtualization Engine Server in a 3952 Tape
Frame, and a second TS7520 Virtualization Engine Server is installed in that
frame, and Failover/Failback will be configured, then both TS7520 Virtualization
Engine Servers should have this feature installed. Both the local and target
TS7520 Virtualization Engine Servers must have feature numbers 7421 and 7422
enabled for Network Replication to operate.
v 7422 (Network Encryption) - enables the TS7520 Virtualization Engine to
support the Network Encryption function in the TS7500 V2R1 software. If this
feature is installed on one TS7520 Virtualization Engine in a 3952 Tape Frame,
and a second TS7520 Virtualization Engine is installed in that frame, and
Failover/Failback will be configured, then both TS7520 Virtualization Engines
should have this feature installed. Both the local and target TS7520 Virtualization
Engines must have feature numbers 7421 and 7422 enabled for Network
Encryption to operate.
30 IBM Virtualization Engine for Tape TS7520: Introduction and Planning Guide
v 7423 (Network Compression) - enables the TS7520 Virtualization Engine to
support the Network Compression function in the TS7500 V2R1 software. If this
feature is installed on one TS7520 Virtualization Engine in a 3952 Tape Frame,
and a second TS7520 Virtualization Engine is installed in that frame, and
Failover/Failback will be configured, then both TS7520 Virtualization Engines
should have this feature installed. Both the local and target TS7520 Virtualization
Engines must have feature numbers 7421 and 7423 enabled for Network
Compression to operate.
v 7424 (3494 Support) - enables attachment of a 3494 library to the TS7520
Limited Edition. Although the actual library is not emulated, the drives can be and
therefore logical volumes can be exported to physical volumes in the 3494
library.
v 7425 (Hosted Backup) - Enables backup operations to be installed on the
TS7520 eliminating the need for a dedicated backup server. Currently TSM and
Netbackup are the supported backup applications for this service.
v 7426 (NDMP) - Enables backup applications and NAS devices to perform backup
and restore using the NDMP version 4 protocol over an IP network. With this
enabled the TS7520 acts as an NDMP server, centralizing management while
eliminating locally attached tape devices from each NAS device. When a backup
occurs, data is moved from a NAS device directly to the virtual library.
v 7427 (Secure Tape) - Enables encryption with one or more keys for data
exported to physical tape and decryption when it is imported back to virtual
tapes. The data on the tape cannot be read or be decrypted without using the
appropriate key.
v 7428 (iSCSI) - Enables SCSI commands to be used over an IP network and
allows hosts to connect via ethernet instead of requiring fibre channel. If this
feature is installed on one TS7520 Virtualization Engine in a 3952 Tape Frame,
and a second TS7520 Virtualization Engine is installed in that frame, and
Failover/Failback will be configured, then both TS7520 Virtualization Engines
should have this feature installed.
v 7428 (Local Replication) - Enables making a copy of a complete virtual volume
in the same TS7520 server. This acts exactly the same as network replication
except the target and source servers are the same.
v 7430 (Enhanced Tape Caching) - This function is included in the Enterprise
Edition software. Enhanced Caching enhances the functionality of the TS7520 by
acting as a cache to a physical tape library, providing transparent access to data
regardless of its location. With the Enhanced caching option, tapes will always
appear to be inside virtual libraries and will be visible to the backup application
regardless of whether the data is actually on disk or tape. This means that the
backup application will always have direct access to data regardless of whether
the data is on disk or on physical tape.
Note: Two optional adapters can be ordered on the TS7520 Virtualization Engine
Server to provide host, tape and iSCSI connections.
v 3450 - Dual-4Gb/sec FC port card – Used for all fibre channel (FC)
connections. FC 3450 support multi-WWPN mode for failover operations and
FCTAPE profile. FC 3450 can be used for host target FC cards or tape initiator
cards in slots 3-6. Slot placement order: 3, 4, 5, 6.
Note: Slots 1 & 2 will always be filled with FC adapters for disk subsystem
attachment (except in the case of the TS75202 LE (Limited Edition)
product offering, where only 1 slot -- slot #1 – will be used).
Chapter 3. TS7520 components and feature codes 31
v 3451 - Quad-1Gb/sec Ethernet port card - Used for iSCSI and customer
network connections. Ethernet port bonding is supported. Slot placement order:
6, 5, 4, 3.
Note: Up to four cards are available for host connection: any combination of
fibre channel (dual ports) or Ethernet (quad ports). A minimum of one card
is required for host connection. Up to two fibre channel cards (4 ports) can
be dedicated to physical tape connection. Up to two ethernet cards (8
ports) may be used for network replication connections.

Advanced features for the TS7520 Virtualization Engine Server (3954
CV6)
The following sections provide additional detail about the following advanced
features available for the TS7520 Virtualization Engine (3954 CV6).
v “Failover/failback”
v “Network replication” on page 51
v “Network encryption” on page 51
v “Network compression” on page 51
v “Secure Tape” on page 52
v “NDMP” on page 52
v “iSCSI” on page 52
v “Hosted Backup” on page 52
v “Control Path Failover and Data Path Failover” on page 52
v “Enhanced Caching” on page 52
v “4-way node support” on page 52
Note: If any of these advanced features are installed in one TS7520 Virtualization
Engine Server in a 3952 Tape Frame, and Failover/Failback will be
configured, and a second TS7520 Virtualization Engine is present in the
3952 Tape Frame, the second TS7520 Virtualization Engine Server must
also have the feature installed.
Failover/failback
Note: Failover is supported for Fibre Channel and SAN/IP only.
To support mission-critical computing, TS7520 Virtualization Engine failover/failback
support provides high availability for the entire storage network, protecting you from
a wide variety of problems, including:
v Storage device path failure
v TS7520 Virtualization Engine Server failure (including storage device failure)
If activated, the failover/failback feature enables active/active failover/failback
without dedicated standby ports. This feature requires two servers.
TS7520 Virtualization Engine supports active-active failover to eliminate single
points of failure. In an active-active configuration, 3954 CV6s monitor each other for
failure conditions. If a failure condition is detected, the functioning 3954 CV6
50 IBM Virtualization Engine for Tape TS7520: Introduction and Planning Guide
automatically takes over the resources of the failed 3954 CV6. Resources include
virtual libraries, virtual drives, virtual tapes, client configurations, and so on. Fibre
Channel WWPNs are also moved (spoofed) so that clients are unaware that the
resources have been moved to a different node.
In a failover scenario, the outage time is usually no longer than a few minutes.
If a 3954 CV6 fails, then the second 3954 CV6 takes over the responsibilities of the
failed 3954 CV6 in a transparent manner to maintain continued access to data.
Active jobs may fail when a failover occurs, possibly requiring job restart.
For additional information about the failover/failback feature, see the IBM
Virtualization Engine for Tape TS7520 User Guide.
Network replication
This involves copying a complete virtual volume from one TS7520 server to another
across an IP network. At prescribed intervals, when the tape is not in use, changed
data from the primary virtual tape is transmitted to the replica resource on the target
server so that they are synchronized. The target server is usually located at a
remote location. Under normal operation, backup clients do not have access to the
replica resource on the target server. If a disaster occurs and the replica is needed,
the administrator can promote the replica to become the primary virtual tape so that
clients can access it.
The network replication feature protects the data on a virtual tape by maintaining a
remote copy of the virtual tape on another TS7520 server accessible over the IP
network. The other remote server may be any distance away, as long as it is
accessible via a network connection.
For additional information about the network replication feature, see the IBM
Virtualization Engine for Tape TS7520 User Guide.
Network Replication Disaster Recovery Testing Support: This function is
implemented when users are given READ-ONLY access to replica virtual tapes for
testing. This is accomplished through first suspending replication, followed by
testing with the read-only volumes and concluded by resuming replication.
Network encryption
The network encryption feature secures data transmission over the network during
replication. Initial key distribution is accomplished using the authenticated
Diffie-Hellman exchange protocol. Subsequent session keys are derived from the
master shared secret key.
For additional information about the network encryption feature, see the IBM
Virtualization Engine for Tape TS7520 User Guide.
Network compression
When activated, the network compression feature supports compression of data
that is being replicated to remote TS7520s. Network compression reduces network
traffic and potentially improves the overall performance of network replication.
Network compression is not to be confused with the enablement of software
compression of incoming data prior to being written on the virtual cartridge.
For additional information about the network compression feature, see the IBM
Virtualization Engine for Tape TS7520 User Guide.
Chapter 3. TS7520 components and feature codes 51
Secure Tape
Uses the Advanced Encryption Standard (AES) algorithm published by the National
Institute of Standards and Technology, an agency of the US government. With this
option, you can create one or more keys that can be used to encrypt the data when
it is exported to physical tape and decrypt when it is imported back to virtual tapes.
The data on the tape cannot be read or be decrypted without using the appropriate
key.
NDMP
The NDMP backup support option allows backup applications and NAS devices to
perform backup and restore using the NDMP version 4 protocol over an IP network.
With this enabled the TS7520 acts as an NDMP server, centralizing management
while eliminating locally attached tape devices from each NAS device. When a
backup occurs, data is moved from a NAS device directly to the virtual library.
Note: This option is not needed when presenting a virtual tape library over FC to a
NAS filer as a replacement for a physical library.
iSCSI
This option allows SCSI commands to be used over an IP network and allows hosts
to connect the ethernet instead of requiring fibre channel. The supported host
platforms are Windows and Linux.
Hosted Backup
The Hosted Backup option makes virtual tape libraries and drives available to local
system by allowing backup applications to be installed directly on to the TS7520,
eliminating the need for a dedicated backup server. Currently TSM and Netbackup
are the supported backup applications for this service.
Control Path Failover and Data Path Failover
Control Path Failover works in the following way: in the event of a loss of a host
adapter or control path virtual drive, the failover mechanism is designed to provide
automatic control path failover to a pre-configured redundant control path without
aborting the current job in progress. The Data Path Failover is designed to provide
a failover mechanism for configuring multiple redundant paths in a SAN
environment. In the event of a path or component failure, the failover mechanism is
designed to automatically provide error recovery to retry the current operation using
an alternate, pre-configured path without aborting the current job in progress. This
can provide flexibility in SAN configuration, availability, and management.
Enhanced Caching
The Enhanced Caching option enhances the functionality of TS7520 by acting as a
cache to a physical tape library, providing transparent access to data regardless of
its location. With the Enhanced caching option, tapes will always appear to be
inside virtual libraries and will be visible to the backup application regardless of
whether the data is actually on disk or tape. This means that the backup application
will always have direct access to data regardless of whether the data is on disk or
on physical tape.
4-way node support
This permits the sharing of all virtual media among all four potential CV6 servers.
Any virtual library’s medium changer and media will be available to any CV6
(subject to the user-specified definitions). CV6s will maintain their own virtual drives
and failover will only be done to a preassigned CV6 housed in the same rack. In
addition, implementation of the virtual pass-through function which permits volumes
to be moved between CV6s via a shared virtual shelf or vault will be performed.
52 IBM Virtualization Engine for Tape TS7520: Introduction and Planning Guide
Command Line Interface
Most operations that can be performed via the console GUI can also be performed
through a command line interface. This will allow for scripting of repeatable tasks.
Network Replication Interoperability
Network replication will allow any approved hardware version of the TS7520 running
version 2 release 1 software to have the ability to perform network replication with
any other approved hardware version of the TS7520 running version 2 release 1
software.
iSeries Support
iSeries support similar to that provided via an RPQ for TS7510 will be provided in
this release. In addition to the functionality provided by the RPQ, certain cosmetic
enhancements will be made to make the system more robust.

The console program and machine are required to complete the installation of the
TS7520.
A VE Console is used for configuration, management, and service support for the
TS7520 Virtualization Engine. This console is required by the TS7520 and is either
supplied by the customer or optionally can be ordered from IBM. If a VE Console
machine is ordered, it is placed as a separate order from the TS7520. You must
insure the console machine is available and ready to install the console program
before they plan to activate the TS7520. For more details on the console machine
requirements, see “TS7520 Virtualization Engine VE Console requirements” on
page 71.
The Console & Capacity Support feature, must be installed on a customer supplied
VE Console based workstation. See “TS7520 Virtualization Engine VE Console
requirements” on page 71 for the minimum requirements of the Console machine. If
a platform with the proper configuration is not currently available, one will need to
be ordered.
Note: The ’per server’ features of the program may only be installed on a TS7520
Virtualization Engine, or subsequent IBM replacements of the TS7520
Virtualization Engine. These features will be preloaded on each new TS7520
Virtualization Engine manufactured.
If any of the following optional hardware features on the TS7520 Virtualization
Engine Server (3954 CV6) are ordered and installed, then specific corequisite
software features must also be ordered and installed as described below. Hardware
features that enable advanced functions must be installed by the IBM Service
Representative. Software Features are installed by the customer.

Chapter 4. Sizing, configuration, and usage considerations
This chapter addresses some of the key challenges in determining an appropriate
match of the TS7520 Virtualization Engine to your needs and provides aid in setting
appropriate expectations both for functional capabilities and performance. This
chapter addresses:
v Basic configuration recommendations for a TS7520
v Sizing considerations to help determine how many TS7520s may be required to
fit your needs
v Impact of associated system components
v Specific advanced features and their role in fulfilling your shop’s data protection
requirements
v System-level implications of designing a data protection architecture around
various usage modes for the TS7520
Default library configuration
Shipped from the factory, you can order the TS7520 single TS7520 Virtualization
Engine Server (3954 CV6) configuration in either the Limited Edition configuration
or the Enterprise Edition configuration. With the Enterprise Edition, you also have
the option of a failover configuration (two TS7520 Virtualization Engine Servers) or
dual failover pairs in a four node system (two TS7520 Virtualization Engine Servers
in the first-base frame and two TS7520 Virtualization Engine Servers in the second
space frame). In a single-server configuration, all available disk storage is allocated
to the one virtualization server, while in a failover or four node configuration, the
disk storage is split evenly between all virtualization servers.
Each TS7520 Cache Controller (3955 SV6) or TS7520 Cache Module (3955 SX6) is
split into multiple logical disk drives; either all logical drives are allocated (or
″enlisted″) for the single virtualization server or, on a per disk drawer basis,
individual logical drives are enlisted for any of the other virtualization servers
present in the system. Every disk drawer in every frame has one spare SATA drive,
which may be used by any logical drive in the disk subsystem controlled by a given
virtualization server. A typical 3955 SV6 or 3955 SX6 disk drawer yields two RAID 5
groups (one 7 disk and one 8 disk). With RAID 5 protection and the 500GB drive
capacity and one hot spare, the 7 disk group yields two 1.43 TB logical drives and
the 8 disk group yields two 1.67 TB logical drives.
The default configuration is determined when the TS7520 system is built and the
manufacturing decision is made whether it is to be a failover or non-failover system.
In the default configuration, the following applies for each virtualization server. Two
default libraries are present:
v Each virtual library is a virtual 3584 frame and twelve virtual LTO 2 drives are
defined.
v Based on the available disk storage enlisted, the maximum quantity of virtual
200GB LTO 2 cartridges that could be created in the available space is defined.
v Volumes are created with a default labeling convention:
– VEOOOOL2, ... , VEOOOnL2 for the first library (accessible on the card in
PCI slot 3, port 1 assuming the card is present)
– VE1000L2 , ... , VE100nL2 for the second library (accessible on the card in
PCI slot 4, port 1 assuming the card is present)
© Copyright IBM Corp. 2005, 2007 57
v No LUN masking is active and all attached initiators have access to all virtual
resources.
v Each virtual library is configured with 253 virtual cartridge slots.
In the case of a field installation of a second virtualization server in an existing
frame, the disk logical drive (LUN) enlistment and the definition of virtual libraries,
drives and libraries will not occur by default; it must be specified by the user. The
system administrator must take care to understand how available (free) disk LUN
space is to be allocated; the factory defaults of 50/50 splits between the two
virtualization servers will no longer apply in this case. Special care must also be
taken when an additional base frame is added to the system because all of disk
storage must be seen by all four nodes of the system.
Note: You can override the factory defaults of space allocation, even for
factory-built failover configurations.
Variations on the configuration defaults
Configured in this manner on start up, the TS7520 is immediately usable, even
without the attachment of the Management Console GUI. Nevertheless, the
expectation is that most customers will want to customize their configuration. This
can be done by adding more virtual volumes or drives.
Space is only allocated from the disk pool as needed, so if a particular volume will
only require 10GB, for example, rather than 200GB, 10GB is all that is actually
used from the disk pool. As a result, you may have many more 200GB virtual
volumes defined than you have physical disk space to accommodate. In addition, if
you want to force an end-of-volume condition early (for example, you may want a
volume to fill up at 2GB), you simply define the volume capacity to be whatever you
want it to be.
You can also define a volume’s capacity to artificially large, up to 1024 GB. As with
physical tape, you have the option of turning on compression for greater space
efficiency, but compression results in lowered bandwidth performance.
Many other options are available as well, including:
v Defining additional virtual libraries
v Changing the LUN masking, to defining different kinds of virtual drives
v Defining different volume replication and archive policies
v Enabling enhanced caching
These options are discussed further in this chapter.
Basic configuration recommendations
The default library configuration does not suit all customers’ needs. It is only a
starting point to permit immediate usability.
A good understanding of your environment, including attached hosts and
connectivity, applications, workloads, and service level requirements, can result in
the basis for more tailored planning to permit the best configuration and usage of
your TS7520s. The following sections discuss some basics relating to connectivity
and base library definition. You have the option at the outset of deleting all default
configurations and redefining configurations to exactly meet your needs.
58 IBM Virtualization Engine for Tape TS7520: Introduction and Planning Guide
HBA target mode and initiator mode
Depending on the number of additional fibre Channel cards (up to four), each
TS7520 server can provide up to four 4Gb fibre channel ports for host attachment
and up to four 4Gb fibre channel ports for physical tape attachment. The most basic
decision to make about the TS7520 setup is whether you want to have direct
physical tape attachment to exploit features such as auto-archive (physical tape
copy on export) and enhanced caching, or whether you want all physical tape
production to be fully managed by the ISV applications driving the TS7520.
In the latter case, which provides the greatest control, the physical tape is not
attached to the TS7520 but is attached to the host fabric in parallel with the
TS7520. In this case, a TS7520 provides up to four ports for host fibre channel
attachment. The use of three or four ports for host I/O can enable the TS7520 with
higher bandwidths than what can be achieved through two ports. Sustained rates
well in excess of 1200 MB/second have been measured in this configuration, even
with a single TS7520 Virtualization Engine Server (3954 CV6) attached to two
TS7520 Cache Controllers (3955 SV6s), each with three TS7520 Cache Module
(3955 SX6s). The TS7520 Management Console provides the means to change any
of the remaining ports from initiator mode (driving physical tape) to target mode
(accepting host commands).
Zoning and LUN masking
Library control path and drive data path failover is currently supported for the
TS7520 Virtualization Engine as a chargeable feature. This allows for multiple host
connections to the TS7520 and correspondingly primary and alternate paths and
drives as seen from the host. When control path and data path failover are not
configured, the best management of pathing where hosts are attaching through a
SAN fabric results in a zoning configuration in which each host-port-to-TS7520-port
connection is isolated in its own zone.
Note: Zoning is defined and managed at the Graphical User Interface (GUI)
provided for controlling a switch fabric; it is not under the control of the
TS7520.
Either hard or soft zoning may be used in the case of a single TS7520 3954 CV6.
In the case of a dual TS7520 3954 CV6 (failover) configuration or four node (dual
failover pairs), soft-zoning provides the greatest simplicity and flexibility. In the
failover case, you must ensure physical (fabric) connectivity of the host fibre
channel port to both the fibre channel port of the primary virtualization server
(where the virtual library of interest is defined) and to the corresponding fibre
channel port of the secondary virtualization server. Because nodes cannot failover
between frames (a four node system is actually two failover pairs), it is not
necessary to ensure physical connectivity from the host fibre Channel ports
connected to nodes in one frame to those of another frame.
After physical connectivity is ensured for failover partners in the same frame, the
soft-zone only needs to specify the World-Wide Port Name (WWPN) of the host
(initiator) port and the primary virtualization server (target) port. On failover, the
WWPN identity of the failing virtualization server is shifted to the surviving failover
partner (the secondary virtualization server in the same frame). Alternatively, if your
switch fabric only supports hard zoning, then your zone needs to include the switch
port to which the host is connected, as well as the switch port to which the primary
virtualization-server-participating port is connected and the switch port to which the
secondary virtualization-server-corresponding switch port is connected.
Chapter 4. Sizing, configuration, and usage considerations 59
In a complex environment, many zones will overlap (each host port may be a
member of multiple zones and each TS7520 port will be a member of multiple
zones), so greater control may be achieved by the use of LUN masking (also
known as LUN mapping) using the TS7520 Management Console. Without LUN
masking defined, every virtual device accessible via a TS7520 port is visible to
every host initiator attaching that port. With LUN masking , you can make certain
virtual devices invisible to some hosts. By this means, you can effectively dedicate
certain virtual drives and/or libraries to certain applications and achieve some level
of static load balancing as well.
Virtual libraries: Sharing and capacity planning overview
The following topics discuss sharing and capacity planning for virtual libraries.
Determining numbers of virtual libraries and virtual drives
At the minimum, the sharing of a virtual library permits shared access to the virtual
volume data, whether or not specific virtual drives are shared or the systems
sharing the virtual volumes use disjoint sets of virtual drives. Sometimes there is a
need to share a virtual library across applications. Usually, however, a single virtual
library is dedicated to the use of a single application, even if multiple hosts connect
to the same library. Some applications might manage sharing of (virtual) drives
across hosts, and while the TS7520 does support multi-host sharing of virtual
drives, this is not necessary for sharing the virtual volume data.
As a starting point then, one can determine the number of unique virtual libraries to
be created based on sets of distinct applications or application-business unit
combinations to be supported, where the key is determining the boundaries of the
need to share data.
For example:
Three distinct business units use application A, but want their data managed
separately with no possibility of the data from one unit being accessible by another.
At the same time, all three business units share data managed or created by
application B. In this example, it is recommended to create four distinct virtual
libraries.
v Three libraries would be created for hosting application A, with each library
uniquely holding the data relating to one of the three business units.
v One library would be created for hosting application B, with the library holding the
shared data relating to all three of the business units (or data for which common
management posed no business risk). Application B might be sufficiently
sophisticated to support management of shared virtual drives within the shared
library as well, but more basic applications might not, in which case it would be
prudent to define three distinct groups of virtual drives, each with appropriate
LUN masking defined to limit their visibility to just a single attaching host. In other
cases, such as in some LAN-free client access environments, it might be
desirable to support having an application server mount and label virtual
cartridges, whereupon an application client may begin direct-writing to the
cartridge, favoring the support of shared virtual drives.
The maximum number of virtual drives to define within a virtual library in a TS7520
depends on both the maximum number of concurrently mounted volumes any user
job requires and the maximum number of user jobs that can be supported at one
60 IBM Virtualization Engine for Tape TS7520: Introduction and Planning Guide
time. This latter factor will be determined by knowing what average bandwidth a
given job can sustain (if not tape-limited) and must sustain to meet its service level
requirements.
If, at most, N user jobs must be run simultaneously and user job j (where j = 1, ...,
N) uses a maximum of d(j) drives simultaneously, each at a data rate r(j,i) (where
i=1, ..., d(j)), the aggregate bandwidth demand of these is:
Bandwidth Demand = Sumj = 1, ..., N
(Sumi = 1, ..., d(j)
r(j,i))
For a single virtualization server (3954 CV6) with only two host fibre channel ports,
the Bandwidth Demand should be configured to be less than 900 MB/second, which
is less than the 1000MB/second the two ports can sustain. This is a very rough rule
of thumb, based on the notion that an aggregate bandwidth demand may vary, and
that one should accommodate peaks that can exceed the average in order to avoid
exceeding service level agreements for job run times.
Note: While this discussion was carried out in the context of a single virtual library,
the logic applies equally to the aggregate of virtual drives in all virtual
libraries defined within a single virtualization server (3954 CV6).
If four ports are available for host connection on a single virtualization server (3954
CV6), then the top bandwidth for the 3954 CV6 will be closer to 1200MB/second,
with 1100 MB/second being a prudent target . Achievable bandwidths,
unconstrained by other system factors, will vary as a function of application block
sizes used, whether or not compression is active, and whether or not other
functions are in use (such as network replication, network encryption, and
compression). You may notice that the top bandwidth for four fibre Channel ports is
not double that of two fibre Channel ports connected to hosts. This is because at
this rate, the virtualization server is not the limiter; the limiter instead is the
sustainable SV6 bandwidth.
Because each 3954 CV6 virtualization server accesses a different SV6, the total
maximum bandwidth is a multiple of the maximum bandwidth obtainable from a
single 3954 CV6 virtualization server. This means that with two TS7520 3954 CV6
virtualization servers, the maximum bandwidth would be 2400MB/second and with
four virtualization servers would be 4800MB/second.
One more important item to note is that if the TS7500 V2R1 software is installed on
TS7510 3954 CV5 servers, the bandwidth will be limited to half of what it is with the
TS7520 3954 CV6 servers because 2 Gb fibre Channel ports are used instead of
the new, 4 Gb fibre Channel ports.
iSCSI considerations
With the TS7500 V2R1 software comes the ability to use iSCSI and ethernet ports
for host attachment. The TS7520 has the ability to contain up to four Quad port Gb
ethernet cards which when combined with the two planar Gb ethernet ports
provides a maximum of 18 Gb ethernet ports that can be used for possible iSCSI
host connection. This may seem unwieldy, but with the port bonding available for all
ethernet ports in a given machine running TS7500 V2R1 software, any combination
of bonded ports can be used to reduce the number of actual IP addresses that are
required. The maximum throughput of a single ethernet port is 125 MB/second, but
with the iSCSI protocol comes overhead and the actual maximum throughput is
approximately 87 MB/second. We recommend using 75 MB/second as a good rule
of thumb. With this figure it would take 14 of the gigabit ethernet ports to be bonded
Chapter 4. Sizing, configuration, and usage considerations 61
together to equal the approximate throughput of two of the fiber Channel ports. This
also means that it would take more than 16 Gb ethernet ports bonded together to
begin to saturate the 1200 MB/second sustainable bandwidth on the attached disk
cache.
Virtual libraries and physical libraries: Differences in capacity planning
Capacity planning in a virtual library environment and a physical library environment
have similarities, but also significant differences. In both cases, knowledge of
workloads forms the basis of good planning. The following describes the
characteristic differences between the two environments:
v Accessors
– Physical libraries have a limited number (usually one or two) of cartridge
accessors (or ″robots″) to mount tape cartridges. These accessors take at
least several seconds to pick and mount cartridges. Mounts can queue waiting
on this resource.
– Virtual libraries have virtual accessors which logically mount virtual cartridges
in milliseconds (at most). Queuing on the accessor is essentially non-existent.
v Load/unload and locate times
– Physical drives will have load and unload times that can vary from 5 to 20
seconds (or more) on load to over a minute on unload . Locate times can
match maximum unload times.
– Virtual drives will have virtual load and unload times which take milliseconds
(at most). Locate times are similar.
v Read/write times
– Physical drives can have worst-case read or write times (in error retry
scenarios with repositioning and wrap refreshing) that can exceed 20 or 30
minutes.
– Virtual drives have no counterpart to long read or write times. Even error
recovery scenarios typically run at most a few seconds.
v Aggregate bandwidth
– Aggregate bandwidth for physical libraries scales linearly with the number of
available drives. The limiters will be other system elements (such as logical
job structure, disk I/O, fabric limitations, and other contending I/O on the
hosts’ fibre channel adapters).
– Aggregate bandwidth for virtual libraries scales semi-linearly (with increasing
numbers of active drives) only up to a point of virtual library subsystem
saturation. At that point, increasing the number of active drives has no impact
on overall aggregate bandwidth, and the maximum per-drive bandwidth begins
to drop in proportion to the total number of active drives.
v Capacity
– Physical cartridges have a fixed capacity, which is determined at the time of
purchase (subject to the potential compressibility of the data written to them).
A given physical library’s ultimate capacity is strictly determined by available
slots, cartridge capacity, and data compressibility. For most open systems not
storing totally random data, compressibility is roughly 2:1 for typical drive
compression algorithms. Individual drive bandwidth is the usually the same
whether compression is active or not. Unused cartridge capacity is wasted .
– Virtual cartridges may be defined with any desired capacity, from very small
capacities that may be less than 1% of the native capacity of the specified
emulated media type, to very large capacities (up to 1024GB in the case of
the TS7520). Virtual slots may be added as desired to support more virtual
cartridges. With capacity-on-demand allocation, unused virtual cartridge
62 IBM Virtualization Engine for Tape TS7520: Introduction and Planning Guide
capacity wastes little or no underlying disk space. Virtual library data
compression, on the other hand, typically slows down effective single drive
data rates significantly, even though it expands effective library capacity.
Virtual libraries and physical libraries: Similarities in capacity planning
The basic determination of capacity requirements (total terabytes of data) for a
library are effectively the same for physical and virtual libraries. In the case of
backup data, capacity depends on the number of generations of backup data to be
held, the size of the disk systems being backed up, and the relative use of full
backups as opposed to incremental or differential backups. For a given host,
consider the size of data to be backed up and the average amount of data changed
per day (or backup period).
For example:
An organization has 400 GB of customer data and 5% of that data is changed each
day. A full backup requires 400 GB. A daily incremental backup requires 20 GB. If
two weeks of data is to be kept, the total data is: 2x400 GB plus 6x20 GB = 920
GB (assuming the organization does not need incremental backups from two weeks
ago). If the application supports differential or cumulative backups, this number may
be less. Consider each application and the different hosts involved. Sum over the
set of hosts and applications to be backed up. For the TS7520, keep the total
capacity under 832 TB for a single or dual virtualization server(s) (3954 CV6) and
under 884 TB for a 4 node/server system. If expected bandwidth to achieve backup
window exceeds the capacity of the TS7520, then reduce the number of hosts or
reschedule backups so they do not all overlap. It should be noted that the 832 TB
maximum capacity for a single or dual virtualization server configuration consists of
a full base frame of storage and 10 expansion frames, which although it is possible
may not be practical performance wise. It is recommended that if 10 expansion
frames are going to be used, that a four node/server system be used as well.
Virtual volume space allocation schemes and disk LUN enlistment
Unless you are concerned about virtual media which is expected to fill completely to
capacity in all cases, choose capacity-on-demand (the default if no choice is made)
to control disk space allocation to virtual tape volumes. The capacity-on-demand
scheme allocates only 5-GB segments at a time, with the first segment not
allocated until the tape is first mounted and written. While this may not afford the
optimal sequential read or write performance with the disk cache, the segment size
is sufficiently large that performance will not be significantly degraded and space
management will be optimal (with fixed segment sizes). You have the option of
overriding the default allocation scheme.
Except where you are converting an existing TS7520 to a 2 node or 4 node
configuration, you should allow the virtualization server (3954 CV6) to manage the
disk LUN enlistment. This results in better I/O balance and performance. In general,
if virtualization servers with significantly different workload aggregate bandwidth
demands run any single 3954 CV6 to near-saturation, this may suggest a need to
rebalance if service level commitments are not being met.
The practical implementation of a rebalancing between 3954 CV6s involves the
creation of a new virtual library on the lightly loaded 3954 CV6. The implementation
also involves the copying of the virtual volumes from the original virtual library to the
new one under ISV application control to maintain application awareness of data
location.
Chapter 4. Sizing, configuration, and usage considerations 63
Additional capacity planning considerations
The following summarizes additional capacity planning considerations:
v Failover impacts
When failover is enabled, all capacity and virtual resources will fail over. In this
case a single virtualization server (3954 CV6) handles the workload normally
handled by two virtualization servers. Jobs in heavily loaded environments may
experience elongation during the failover period. Be sure that performance is
tolerable in failover state. Check the guidance in this chapter and
application-specific performance as further guidance becomes available in
whitepapers.
v Network replication impacts
Reserve space for the replica resource area for all cases where a TS7520 will be
a target of network replication from a remote TS7520. The replica resource area
directly detracts from the available space for local libraries’ virtual cartridges.
v Virtual Vault residency impacts
Reserve space for the virtual vault (or virtual ″shelf″) for auto-archive operations
(physical tape copy on export) or others (such as manual copy) where tapes are
temporarily moved to the virtual vault prior to copying. This is especially
important if you are running in copy mode rather than move mode, or if you are
running in move mode with a long grace period prior to deletion. The virtual vault
area directly detracts from the available space for local libraries’ virtual
cartridges.
v Access density considerations
Use the size of the available backup window to calculate the data rate required
to support it. If the rate cannot be supported by the TS7520, then split the
backup task into multiple components, reducing the single-threaded
characteristics either on the application host side (breaking into tasks for multiple
hosts) or on the target side (breaking into multiple backup streams targeting
different volumes simultaneously), or both.
v Compression considerations
Determine if you are space-constrained or backup-window-constrained. If you do
not have backup window constraints, then consider enabling 3954 CV6
compression. Performance can significantly drop with use of 3954 CV6
compression, especially with relatively incompressible data.
v Tape attachment or tapeless 3954 CV6
Use of the auto-archive (physical tape copy on export) or enhanced caching
function reduces the load on the application backup server but has no effect on
the 3954 CV6 (reading data from the 3954 CV6 for external copy to a physical
tape drive via the backup server as opposed to having the 3954 CV6 do the
writing to the external physical tape drive locally attached to it using the
auto-archive or enhanced caching function).
v Concurrent stream aggregation
Each virtual drive can be allocated to a specific host application stream. Virtual
media can be appropriately sized for capacity and later aggregated to real media
in an external copy operation.
System application and advanced function considerations
Virtual tape disk-based systems have a number of advantages over disk targets for
backup:
64 IBM Virtualization Engine for Tape TS7520: Introduction and Planning Guide
v Tape targets are nearly universally supported by backup applications and disk
targets are not. This works well even among disparate host types attaching the
virtual library in a SAN.
v Sharing of tape data requires only a mount of a virtual cartridge in a common
virtual library. Sharing of disk data requires a shared file system. Shared SAN file
systems are still not widely deployed and are relatively difficult to set up.
v Tape targets have underlying simple structures with very low overhead on
attaching backup servers. Virtual tape targets eliminate any performance delays
that real tape targets have relative to disk targets.
v Disk targets require file system support on the attaching backup servers with
significantly higher performance overhead. They have no speed advantage over
virtual tape targets.
The following sections examine some environments of particular interest to better
understand how they are configured and what motivates their use.
Tape SAN exploitation: LAN-free backup/restore
LAN-free backup/restore is a configuration most widely supported by tape products
with significant performance advantages. The idea of LAN-free backup is that a
backup server manages the assignment of a drive and tape volume to a given client
backup task, but the data I/O occurs directly from the client to the backup medium
(typically over the SAN, rather than via the LAN through the backup server). This
reduces network traffic and backup server load. Large data object performance is
significantly improved.
Tape LAN-free backup is much more widely supported than disk LAN-free (which
requires a shared file system). The TS7520 supports LAN-free backup as readily as
physical tape but with potentially superior performance because the TS7520 has
none of the mount queue, load, or locate overheads of physical tape.
Figure 7 on page 66 illustrates traditional backup over a LAN to a backup server
which connects via a SAN to a tape library.

TS7520-parallel and TS7520-inline attachment of physical tape
Physical tape can be used in a TS7520 environment in two distinct ways: it can be
directly attached to the backup server and fully managed by the ISV backup
application, or it can be attached to the TS7520 fibre channel ports with modes of
use that are either tied indirectly to ISV backup application management or that are
not managed by the ISV application at all. In general, IBM does not recommend
usage modes that are not managed by the primary backup application or that are
not managed by a customer tape media management system. Such usages must
be manually tracked and managed, and are generally only appropriate to exploit in
exceptional situations. For the current offering, physical tape attachment to the ISV
backup server directly (that is, in parallel to the TS7520) may be a better choice for
many installations where full management of physical media in all situations is
mandatory.
An example of a parallel-attachment configuration would be the use of TSM-based
duplication using copy pools. Here, the TS7520 would be a primary backup target
of a TSM server (possibly also accessible to TSM clients in a LAN-free
SAN-attached environment). A separate physical tape library would also be
connected to the TSM server via the SAN, where some set of cartridges in the
physical tape library would be part of TSM Copy Pool. Writing to the physical tape
would occur as a result of the TSM server copying the TS7520 data into the
physical cartridges. The following characteristics apply in this situation:
v The parallel approach has the advantage of supporting incremental backup of
storage pool data, permitting the physical cartridges as well as the virtual
cartridges to stay resident in their libraries. With direct tape attachment, the copy
to physical tape only occurs if the virtual tape (and the physical tape) are
exported from the library, or if the enhanced caching policy for data migration is
triggered.
v In the parallel approach, the primary (virtual) and duplicate (real) volumes can
have different media types, device types, and device capacities, all of which are
tracked by the backup (TSM) server. With virtual auto-archive, real and virtual
media types, device types, and media labels must match exactly.
v Real copies can be made synchronously (during primary creation) or
asynchronously (after primary creation). With auto-archive, the real copy can only
be made after the original copy is created (asynchronous only), but auto-archive
reduces I/O burden on the backup server.
v Physical tape drives and cartridges attached to the TS7520 must be in a partition
not visible to the backup application (in a medium changer library). Libraries such
as the IBM 3494 are accessed by special library manager commands that relieve
some of these constraints.
v Virtual volumes and real volumes may be managed with different policies (such
as retention periods) in the parallel attachment method. With the inline
attachment method, management policies must be identical between virtual and
real volumes.
On the other hand, the creation of physical tape inline attachment with the TS7520
via the auto-archive (physical tape copy on export) can be considered to be fully
managed. When the backup application exports a (virtual) tape (via a Move Medium
to Virtual I/O Slot command), the virtual medium is moved to the virtual vault (out of
the virtual library) and then it is copied to a physical volume of the same media type
and label. The physical volume is then exported from the physical library. From a
backup application point of view, the exported physical volume is known and
outside of any library, as would be expected. The weakness of this model is that it
Chapter 4. Sizing, configuration, and usage considerations 67
requires the export of the volume to create a physical copy. Re-entry of the virtual
volume into the virtual library requires operator intervention at the TS7520 VE
Console.
v Enhanced caching considerations
One advantage of the inline method is the backup application’s ability to take
advantage of the enhanced caching that is available through the TS7520. With
enhanced caching, the backup application writes and reads data to and from
virtual libraries in the TS7520 as it would normally. The difference, however, is
that caching policies can be set on the TS7520 that define when to migrate data
out of disk cache and onto physical tape contained within an attached physical
library. In this sense, the virtual tape library acts more like a virtual tape server.
When the data has been migrated from disk and onto physical tape, and when
the cache has been reclaimed, the TS7520’s virtual pass through ability allows
the backup application to interact directly with the physical tape without having to
read the data back into the disk cache.
v NDMP considerations
One way to alleviate a backup application’s inability to track changes performed
by the TS7520 with attached, in-line tape is through NDMP. With NDMP, the
backup application has a connection to an NDMP server running on the TS7520
virtualization engine and knows the state of each volume contained within each
library.
The inline method also defines one means by which the data under a TS7520 can
be protected. Other modes of copy and protection of TS7520 data, which are more
flexible, are those which involve replication across the network.
TS7520 network replication key modes and considerations
The TS7520 supports two primary modes of network replication of virtual volume
data between TS7520s. Note that replication occurs over IP links and may involve
transcontinental distances. With the TS7520, up to 10 1Gb Ethernet ports are
available for replication (two planar ports and 8 available through two Quad Port
ethernet cards). Usage of the ports for a given replication task is determined by
what remote TS7520s are visible to a given port. Two modes are supported:
v Network Replication
A virtual volume may be configured for ongoing replication to a remote 3954 CV6
target’s replica resource space. In this configuration, any changes to a given
local volume are reflected to the remote image according to policy (as driven by
time driver or changed data). Network compression to reduce network load may
be specified if licensed, and network encryption to protect data transfer may be
specified if licensed. A replicated volume can only be recalled (or remote-copied)
after it has been promoted into a remote virtual library from the remote replica
resource space. Each virtual volume may have a different target remote 3954
CV6.
Note: Replica resource space takes away from available virtual volume space
within virtual libraries.
v Network auto-replication (virtual tape copy on export)
A virtual volume may be configured for auto-replication to a given remote 3954
CV6 virtual library (not a replica resource). In this mode, a virtual volume is
moved to the virtual vault and copied not to a physical volume (as with
auto-archive) but to a virtual volume. In this mode, the virtual volume is normally
not exported remotely. Each virtual volume may have a different target remote
3954 CV6.
68 IBM Virtualization Engine for Tape TS7520: Introduction and Planning Guide
v Local replication
In addition to the two network replication methods, TS7500 V2R1 provides local
replication as well. With local replication, instead of the remote copy of a
replicated volume being hosted on another server, the copy of the virtual volume
is placed and in other disk LUN accessible from the local server. This provides
the duplication of data but at much faster access speeds than network replication
because it is accessible through the local fibre channel connections.
Failover/failback considerations
Failover/failback can have different application level manifestations. In general, a
failover/failback occurrence appears similar to what would be seen if a host fibre
cable attachment to the tape subsystem was pulled and then later reattached. In
the case of Veritas NetBackup, there is transparent retry of the I/0 in progress, so
NetBackup may normally not require any restart. Failover and failback will be
transparent to it. TSM, on the other hand, may require a task restart (after failure of
the active task) with recovery going back to the last successful synchronization
point on the medium, but the whole TSM region will not be abended and the TSM
server will not require reboot.
Other failoverlfailback behavioral considerations include:
v Failback is as disruptive as failover, except that failback provides the option of
planning its timing to minimize job interruption. Failover for the purpose of system
maintenance, for example, may also be scheduled and manually initiated.
v Failover/failback requires loop mode switch port attachment.
v Failover/failback is not supported for active/passive mode. It is expected that any
failover pair will have primary storage for each 3954 CV6, even if it not perfectly
balanced, as would be the case with a field upgrade to a failover configuration.

Chapter 5. Customer installation responsibilities
Customers are responsible for preparing the installation site, as described in
Chapter 2, “Physical planning specifications for the TS7520,” on page 19, prior to
the installation of the TS7520 Virtualization Engine.
All physical planning for the TS7520 is a customer responsibility. In summary,
customers are responsible for providing network connections (cables and switches),
physical tape libraries, SNMP servers, e-mail servers, host clients, and e-mail
services for Call Home and RSA alerts. Customers must provide IBM with all
necessary IP addresses for the installation of the TS7520.
Customers are responsible for obtaining a VE Console system and for obtaining the
appropriate adapters and cables. Fibre Channel cables are required to attach the
TS7520 to various server adapters. Ethernet cables are required to attach the
TS7520 to iSCSI hosts. Refer to Chapter 3, “TS7520 components and feature
codes,” on page 27 for a list of cables for the attachment of the TS7520
Virtualization Engine. In addition, customers are also responsible for providing client
machines and required Fibre Channel and Ethernet switches as described in the
following sections.
System responsibilities
In addition to meeting the requirements set out in Chapter 2, “Physical planning
specifications for the TS7520,” on page 19, the customer must provide the following
hardware and systems.
TS7520 Virtualization Engine VE Console requirements
The TS7520 Virtualization Engine VE Console system (hereafter called the VE
Console) hosts the IBM Virtualization Engine TS7500 Software Version 2 Release
1. Using the supplied VE Console CD, the customer can install the VE Console
software. IBM recommends that the TS7500 V2R1 Software be installed on the VE
Console prior to the installation of the TS7520 Virtualization Engine.
Note: The license keys required for TS7520 Virtualization Engine feature
enablement require that the TS7500 V2R1 Software for the TS7520 VE
Console be installed and functional before any TS7520 Virtualization Engine
features can be enabled.
The VE Console is used for configuration, management, and service support for the
TS7520. This console is required by the TS7520 and is either supplied by the
customer or optionally ordered from IBM. If a VE Console is ordered, it is placed as
a separate order from the TS7520.
Any general purpose computer meeting the specified hardware and software
requirements may be used for the VE Console. The minimum requirements for the
VE Console are:
v Hardware requirements:

At least one VE Console must be installed within line of sight of the TS7520 3592
Tape Frame no further than 50 feet (15.25 meters) away in order to support a
smooth installation and maintenance process. During normal operation, any
customer TS7520 can be managed from any TS7520 VE Console with network
access to the TS7520 Virtualization Engine Server 3954 CV6.

Hardware, cabling, and infrastructure responsibilities
In general, you are responsible for providing the appropriate infrastructure
resources, such as cables and switches, required to support TS7520 Virtualization
Engine connections to the VE Console, host devices, tape devices.
The following description of the TS7520 Virtualization Engine Server 3954 CV6 will
help in clarifying many of the specific connections to be made to support TS7520
operation.
Four fibre channel ports on each TS7520 Virtualization Engine Server 3954 CV6
are reserved for internal connection between the 3954 CV6 and the TS7520 Cache
Controllers (3955 SV6s). An aggregate of up to eight fibre channel ports are
available for attaching customer backup servers (or backup clients) and customer
physical tape drives.
Note: In target mode, the ports cannot attach physical tape.
Figure 9 on page 75 shows the relationship of each of the physical fibre channel
ports on the QLogic PCI adapter cards, their default usage assignments, and the
logical adapter number (also known as the TS7520 Virtualization Engine VE
Console adapter number) that is assigned to each physical port (as shown in the
VE Console display). Each PCI fibre channel card will have two logical adapters
associated with it, one for each physical fibre channel port. Ports on each PCI card
are numbered left to right (looking at them from the back of the 3954 CV6) as port
1 and port 2. The PCI slots (and the cards that occupy them) on the right side of
the rear of the 3954 CV6 are numbered PCI slot 3 (on top) and PCI slot 4 (on the
bottom). The PCI slots on the left are numbered PCI slot 1 (on top) and PCI slot 2
(on the bottom). Numbering of logical adapters begins with physical ports on the
card in PCI slot 3, then PCI slot 4, then PCI slot 1, and then PCI slot 2.
Table 18 on page 74 summarizes the relationships of VE Console-reported logical
adapters, physical fibre channel ports on the 3954 CV6, and actual usages. In the
cells that contain both an SV6 assignment as well as a switch assignment, the top
assignment is in the case of a single frame system configuration, and the bottom
assignment is the fiber channel switch and port number that would be used in the
case of a multi-frame system. Only adapters from the first four slots are shown
because those are the only adapters that have default target or initiator
assignments. If fibre channel cards are added to the last two slots, those are totally
user configurable.

Ethernet 1 and Ethernet 2 ports carry both the inter-server health monitoring pulse,
replication traffic, call-home traffic, SNMP traps, and management control
information. Both of these physical Ethernet interfaces will carry two IP addresses
(in a failover configuration): one for the health monitoring traffic and one for all other
functions. The RSA Ethernet port carries SNMP traps for the base 3954 CV6 server
service events and provides a port for Service login for field problem resolution.
74 IBM Virtualization Engine for Tape TS7520: Introduction and Planning Guide
Notes:
1. The TS7520 Virtualization Engine configuration steps in some documentation
may refer to ethernet 1 and ethernet 2 as eth0 and eth1. Other documentation
may also indirectly refer to ports 1 and 2 of each fibre channel card as ports 0
and 1. Cards are actually stamped with 1 and 2, which is the preferred naming
convention.
2. Do not change the fibre channel adapters or move the cables in PCI slots 1 and
2. The only portion of the TS7520 cabling that is configurable is the attachments
to PCI slots 3 through 6.
3. The RS485, USB and serial ports are not used for the TS7520. They may be
ignored.
The user must provide the following hardware and cabling resources prior to the
installation of the TS7520 Virtualization Engine.
v Ethernet cables for connecting the TS7520 Virtualization Engine to the VE
Console and iSCSI clients
v Fibre channel cables for connecting the TS7520 Virtualization Engine to the hosts
and tape devices or libraries
v VE Console system, as described in “TS7520 Virtualization Engine VE Console
requirements” on page 71
Note: Any user switches, client host platforms, physical tape libraries, tape drives
or tape media the user may require, has to be provided by the user and
should be secured prior to the installation of the TS7520 Virtualization
Engine.

Zoning overview
You can establish zones for fibre-channel attachments to the TS7520. The zones
must contain a single port that is attached to a system adapter with the desired
number of ports that are attached to the TS7520. By establishing zones, you reduce
the possibility of interactions between system adapters in switched configurations.
You can configure switch ports that are attached to the TS7520 in more than one
zone. This enables multiple system adapters to share access to the TS7520
fibre-channel ports. Shared access to a TS7520 fibre-channel port might come from
host platforms that support a combination of bus adapter types and the operating
systems.
Zoning is configured by the user interface provided by your switch fabric. You can
establish the zones by using either of two zoning methods:
v Port number (hard zoning)
Hard zoning is zoning using the port numbers of the switches. This is usually
more tedious to maintain.
v Worldwide port name (WWPN) (soft zoning)
Soft zoning uses the WWPNs in the configuration. The WWPNs will remain the
same in the zoning configuration regardless of the port location.
IBM recommends soft zoning because it minimizes the number of zones needed in
a failover setup and it simplifies port assignment on the switch.
Attention: IBM strongly recommends setting up individual zones for each host
initiator HBA port and TS7520 HBA port connection that is to be supported.
v If soft-zoning is used, the zone may specify the WWPN of the host HBA port and
the HBA port of the primary 3954 CV6 containing the virtual libraries during good
(not failed over) operation. In the case of failover, the WWPN of the failing 3954
CV6 will be assumed or spoofed by the surviving failover partner, and as such
will still be in the recognized zone.
v If the switch fabric only supports hard zoning, then for failover configurations a
hard zone should be created with the host HBA port and both the port on the
primary 3954 CV6 being used for accessing the virtual library as well as the
corresponding port on the failover partner.
In simple non-failover configurations, both hard and soft zoning should be
configured with exactly one host HBA port and one TS7520 HBA port. This zoning
strategy limits the possibility for undesired configuration side effects, such as
initiators trying to log into each other. The same logic applies to TS7520 initiator
ports and physical tape target ports. Note that zones are not partitions: a given HBA
may be in many different zones.
TS7520 zoning considerations
For example, for the case of upstream (Client Host or Backup Server) zoning, if
there are two client initiators and two TS7520 Virtualization Engine targets on the
same FC fabric, and if it is desirable for all the four path combinations to be
established, it is recommended that you use four specific zones, one for each path:
v Client_Init1/VE_Tgt1
v Client_Init1/VE_Tgt2
v Client_Init2/VE_Tgt1
v Client_Init2/VE_Tgt2
76 IBM Virtualization Engine for Tape TS7520: Introduction and Planning Guide
It is tempting to simply create a single zone that includes all four ports, which
appears to be have the same effect. However, this causes undesirable side effects
because of the lack of isolation among the initiators and targets. The four-zone
method is cleaner because it does not allow the two Client initiators or the two
TS7520 Virtualization Engine Target ports to see each other. This eliminates all the
potential issues such as Initiators trying to log in to each other under certain
conditions.
Follow the same method for downstream (storage) zoning. If there are two TS7520
Virtualization Engine initiators and two Storage targets on the same fabric, establish
four zones:
v VE_Init1/Storage_Tgt1
v VE_Init1/Storage_Tgt2
v VE_Init2/Storage_Tgt1
v VE_Init2/Storage_Tgt2
Additionally, make sure that the real tape device fibre interfaces that are attached to
the TS7520 initiators are not zoned with the client host HBAs.
As shown in the following illustrations, by default, logical adapters 4and 6(as
reported by the VE Console) are zoned to servers, and logical adapters 5 and 7 are
zoned to the physical tape library.
Figure 10 on page 78 shows a zoning example for a TS7520 Virtualization Engine
SAN configuration with both virtual and physical tape drives.
Note: In this configuration, the backup servers only have direct access to LTO 3
drive B. Any access to LTO 3 drive A is through the TS7520.
Chapter 5. Customer installation responsibilities 77
Figure 11 on page 79 shows a zoning example for a TS7520 Virtualization Engine
SAN configuration with all virtual tape drives.
Note: In this configuration, all access to the LTO 3 drives is through the TS7520.

78 IBM Virtualization Engine for Tape TS7520: Introduction and Planning Guide
LUN masking
After zoning has been established, you may limit the access a given host HBA has
to only those virtual drives you want to make visible to it, regardless of the access
provided by the physical connection and zone residency. The TS7520 provides a
LUN masking facility which may be used to specify which virtual device accessible
by a TS7520 port in a given zone may be seen by the attached host HBA in the
zone. This can facilitate sharing of virtual libraries, if needed, and static load
balancing. In general, virtual libraries are not shared among hosts, but the LUN
masking facility permits this to occur in a controlled fashion.

Chapter 8. Planning data migration
Use these data migration considerations to formulate your data migration plan.
There are three levels of considerations to keep in mind when selecting the best
method for your environment. At the first level, you consider broad questions about
your environment to create a generic profile of your needs. At the second level you
compare which migration methods fit into your generic profile. The level is to review
a set of hints and other guidelines that apply to specific environments or that may
help you take advantage of a migration to optimize your environment.
The following are some key questions to use to define your generic migration
environment
v Why is the data migrating?
v How much data is migrating?
v How quickly must the migration be performed?
v What duration of service outage can be tolerated?
v Is the data migration to/from the same type storage?
v What resources are available for the migration?
After determining general answers to the considerations listed above, a better
understanding of some of the migration options along with their advantages and
disadvantages will help frame your generic profile into a subset of acceptable
migration options.
