Figure 2: IBM Storwize V7000 Unified Architecture

The IBM Storwize V7000 File Module Software within the Storwize V7000 Unified system contains the interface-node and management node functions. A management node is used for configuring, administering, and monitoring a system. An interface node connects a system to an Internet Protocol (IP) network.

The Storwize V7000 Unified software performs the following functions for the host systems that attach to Storwize V7000 Unified:

• Creates a single pool of storage • Provides logical unit virtualization • Manages logical volumes • Mirrors logical volumes

The Storwize V7000 Unified system also provides the following functions:

• Large scalable cache • Copy services

− IBM Tivoli® Storage FlashCopy® Manager (point-in-time copy) function, including thin-provisioned FlashCopy to make multiple targets affordable

− Metro Mirror (synchronous copy) − Global Mirror (asynchronous copy) − Data migration


6

• Space management − IBM System Storage® Easy Tier™ to migrate the most frequently used data to higher

performing storage − Metering of service quality when combined with IBM Tivoli Storage Productivity Center − Thin-provisioned logical volumes

This offers customers great flexibility in meeting their storage needs, irrespective of whether file-based or block-based.

Storwize V7000 Unified system NDMP overview

IBM Storwize V7000 Unified system supports the NDMP version 4. NDMP is a network-based protocol used by data management applications primarily for backing up and restoring the files contained within a NAS system, such as IBM Storwize V7000 Unified system.

The Storwize V7000 Unified system NDMP feature provides the capability to backup and restore the files and directories within file systems of the Storwize V7000 Unified system. The granularity of backup is at the directory level. NDMP supports the concept of a full backup and an incremental backup. A full backup backs up all files and directories specified by Storwize V7000 Unified NDMP feature. An incremental backup backs up those files and directories that have changed since the last full backup. Incremental backups are cumulative.

A cumulative incremental backup backs up the files that are specified in the backup selections list that have changed since the last full backup. In the event no previous backup has been finished, all the files are backed up. Cumulative incremental backups occur automatically according to the scheduled criteria. A complete restore requires the last full backup and the last cumulative incremental backup.

A differential incremental backup backs up the files that have changed since the last successful incremental (differential or cumulative) or full backup. If no previous backup has been done, all files are backed up. Differential incremental backups occur automatically according to scheduled criteria. A complete restore requires the last full backup, the last cumulative incremental backup, and all differential incremental backups that have occurred since the last full backup.

Storwize V7000 Unified supported NDMP physical configuration There are two primary NDMP configurations that can be used with the Storwize V7000 Unified system.

• Two-way (or remote) NDMP

• Three-way NDMP

The following sections describe the two-way (or remote) and three-way NDMP configurations in detail.


7

Two-way (or remote) Storwize V7000 Unified NDMP configuration

The two-way NDMP consists of an external data management application, such as Symantec NetBackup, running on a server external to the Storwize V7000 Unified system. The data management application system has some form of storage hierarchy, such as a tape library, that it manages for the storage of backup data.

In addition to the external data management application (Symantec NetBackup) system, an Ethernet network exists that connects the data management application system to the Storwize V7000 file modules on which the NDMP server is running. NDMP control and data traffic flow across this network, between the external data management application system and the Storwize V7000 Unified file modules on which the NDMP server is running.

Recommendation: The recommendation is that this network be a high speed 10 Gb Ethernet network to handle the volume of data being backed up or restored. However, nothing prevents this network from being a 1 Gb Ethernet network.

Figure 3 shows an example of a two-way Storwize V7000 Unified NDMP configuration. It includes an external data management application (Symantec NetBackup) running on a server external to the Storwize V7000 Unified system. The data management application server has an IBM System Storage® TS7650G ProtecTIER® Deduplication Gateway attached to it through an 8 Gbps Fibre Channel (FC) SAN. The System Storage TS7650G ProtecTIER Deduplication Gateway has an IBM System Storage DS5000 storage controller attached to it through 8 Gbps FC links, which in turn has some number of DS5000 disk storage expansion units attached to it through 8 Gbps FC links. The data management application is connected to a 10 Gbps Ethernet network to which the Storwize V7000 Unified file modules are attached. In Figure 3, the lines are intended to show the type and speed on the connections between the various physical components and do not necessarily represent the actual number of physical links.


8

Figure 3: Two-way (Remote) Storwize V7000 NDMP configuration

Three-way Storwize V7000 Unified NDMP configuration

In a three-way Storwize V7000 Unified NDMP configuration, an NDMP tape server is installed on a server external to the Storwize V7000 Unified system and separate from the server on which the Symantec NetBackup data management application is running. Some forms of storage devices, such as a virtual tape library or real tape library and tape drives, are attached to the server running the NDMP tape server.

The NDMP controls the traffic flow between the Symantec NetBackup data management application system and the Storwize V7000 Unified file modules. NDMP data traffic flows between the Storwize V7000 Unified file modules and the NDMP tape server. In this scenario, only NDMP control traffic is flowing between the Symantec NetBackup data management application system and the Storwize V7000 file modules. Therefore, the Symantec NetBackup data management application system does not need to be on a high-speed network. The Symantec NetBackup (data management application) system can use a lower speed 1 Gbps Ethernet network to connect the Storwize V7000 file modules and the external server on which the NDMP tape server is running.

However, NDMP data traffic (the actual data being backed up or restored) is flowing between the Storwize V7000 Unified file modules and the external server on which the NDMP tape server is running.


9

Recommendation: It is recommended that the Ethernet network between the NDMP tape server and the Storwize V7000 unified file modules running the NDMP server be a high-speed 10 Gbps Ethernet network.

Figure 4 shows an example of an NDMP three-way configuration. In this example, the Storwize V7000 Unified file modules (used for file serving) and the data management applications are connected on a 1 Gbps Ethernet network. Storwize V7000 Unified file modules used for NDMP backup and restore, are also connected to a 10 Gbps Ethernet network along with the NDMP tape server. The server on which the NDMP tape server is running is connected to an 8 Gbps FC SAN along with an IBM System Storage TS3500 tape library with some FC-attached tape drives, such as IBM Linear Tape-Open data cartridges, Generation 3, Generation 4, or Generation 5 tape drives.

Figure 4: Three-way Storwize V7000 NDMP configuration

Fundamentals of Storwize V7000 Unified NDMP feature The following points explain the fundamentals of Storwize V7000 Unified NDMP features:

• An NDMP version 4 compliant data server is available on file modules of the Storwize Unified storage system. There is a provision to create both the file modules that will be part of an NDMP_NODE_GROUP. Both the file modules are paired with network group IP addresses that can be assigned to a specific network port. This network port is associated with the NDMP service.


10

• The NDMP server running on a file module provides for both data and control connections to

servers external to the Storwize V7000 Unified storage system on which a data management application (Symantec NetBackup) is running.

• The ability to configure the NDMP parameters for file modules (the NDMP_NODE_GROUP) is provided through Storwize V7000 Unified CLI commands that are run from the file module, which stores the NDMP configuration parameters in the Samba Registry.

• In addition to the Storwize V7000 Unified CLI commands available to store and retrieve NDMP

configuration parameters, a set of CLI commands are provided allowing to view NDMP session information and NDMP log information, and stop currently running NDMP sessions.

• An NDMP backup session provides backup of a specific directory in an IBM General Parallel File

System (IBM GPFS™) and all files and subdirectories contained within it. Besides the basic data of the files and directories, all extended GPFS attributes are saved for every file and directory. In order to provide the provision to back up a directory structure at a given point in time, a snapshot is used and it is actually the snapshot of the directory structure that is backed up. This snapshot also accounts for files that might be open or in use during the backup, as a point-in-time representation of the file is backed up by NDMP.

• An NDMP restore session will restore all of the files and directories in the proper structure of

subdirectories, and so on. In addition to the actual file contents, the GPFS extended attributes are also restored.

Storwize V7000 Unified NDMP command-line configuration

The following Storwize V7000 Unified CLI commands (shown in Table 1) are available for configuring, monitoring, and managing the NDMP configuration parameters and NDMP sessions.


11

Table 1: Storwize V7000 Unified system CLI command description

Storwize V7000 Unified system configuration in lab

In the lab:

• The Storwize V7000 Unified system has one Storwize V7000 storage system for block access functionality.

• The Storwize V7000 Unified system has two file modules that act as management nodes, interface nodes, and storage nodes for file-level access: mgmt001st001 and mgmt002st001

• The Storwize V7000 Unified system file cluster is defined as: ifs1isv.storage.tucson.ibm.com • There are 10 Gb Ethernet cards on each file modules and configured ethX1 to access the

bonded ports

(Refer to “Appendix B: Materials used in the lab setup” for more information)

Storwize NDMP network group configuration

This section provides the guidelines to create and configure a network group that includes file modules to service NDMP requests for the NDMP node group.

• Create a network group comprising two file modules using mknwgroup Storwize V7000 Unified CLI command on file modules.

Storwize V7000 Unified NDMP node group configuration using CLI

This section provides appropriate guidelines to create and configure the Storwize V7000 Unified NDMP node group.

• A Storwize V7000 Unified NDMP configuration can be defined only for an NDMP node group. • A Storwize V7000 Unified NDMP node group must be created before any other specific Storwize

V7000 NDMP node group configuration parameters can be set. • A Storwize V7000 NDMP node group is created, configured, and activated appropriately, before

an NDMP backup or restore can be configured on the Symantec NetBackup Data Management Application (DMA) server.

To configure the Storwize V7000 Unified NDMP node group:

1. Create an NDMP node group using the --create option of the cfgndmp command on Storwize Unified file module.

cfgndmp -c ifs1isv.storage.tucson.ibm.com ndmp_node_grp1 --create

2. Attach the newly configured network group, ndmp_nw_group, (refer to the “Storwize NDMP network group configuration” section) to the newly created Storwize V7000 Unified NDMP node group using the cfgndmp Storwize V7000 Unified CLI command with the --networkGroup option on the file module.

cfgndmp -c ifs1isv.storage.tucson.ibm.com ndmp_node_grp1 --networkGroup ndmp_nw_group


18

3. Set the data port range of the NDMP node group using the --dataTransferPortRange option of the cfgndmp command on file module.

cfgndmp -c ifs1isv.storage.tucson.ibm.com ndmp_node_grp1 --dataTransferPortRange 2048-2098

4. Add the file system mount point paths to the NDMP node group configuration using the --addPaths option of the cfgndmp command on the Storwize V7000 Unified file module.

cfgndmp -c ifs1isv.storage.tucson.ibm.com ndmp_node_grp1 --addPaths /ibm/gpfs0,/ibm/gpfs1

5. A default NDMP backup prefetch configuration is assigned to a newly created NDMP node group, with the function deactivated. Optionally, use the cfgndmpprefetch CLI command to change the NDMP backup prefetch configuration and activate the function for improved NDMP backup performance. Refer to the “Configuring Storwize V7000 Unified NDMP backup prefetch” section for more information.

6. Activate the NDMP node group with the --activate option of the cfgndmp CLI command.

cfgndmp -c ifs1isv.storage.tucson.ibm.com ndmp_node_grp1 --activate

Note: You can use the lsndmp CLI command with the -ndmpServiceStatus option to verify that NDMP has started on all the nodes in the NDMP node group, on the Storwize V7000 Unified file module.

lsndmp -c ifs1isv.storage.tucson.ibm.com [-s] [--ndmpServiceSatus]

Figure 14: lsndmp CLI usage

Configuring Storwize V7000 Unified NDMP backup prefetch

The NDMP backup prefetch function navigates the directory that is being backed up, reading files in advance to the files actually coming due to be backed up. The prefetch function opens files in read-only mode and places the files in the file module’s cache for improved backup performance.

NDMP backup prefetch is designed to work on files that are less than or equal to 1 MB in size.

Restriction: Storwize V7000 Unified NDMP backup prefetch will not work for a file system that has a block size that is greater than 1 MB.

• To activate the NDMP backup prefetch feature, use the cfgndmpprefetch CLI command with the --activate option. Specify the NDMP node group to enable NDMP prefetch feature with Storwize V7000 Unified NDMP node group, as in the following example on the Storwize V7000 Unified file module. cfgndmpprefetch -c ifs1isv.storage.tucson.ibm.com ndmp_node_grp1 --activate


19

Note: If NDMP is not active on the specified NDMP node group, a message is displayed indicating that prefetch for NDMP will be activated when NDMP is activated.

• To set a limit for the number of applications that can simultaneously use Storwize V7000 Unified NDMP backup prefetch for a node, (including multiple instances of the same program, such as multiple Storwize V7000 Unified NDMP sessions) use the cfgndmpprefetch CLI command with the --appLimit option, as in the following example on the Storwize V7000 Unified file module.

cfgndmpprefetch –c ifs1isv.storage.tucson.ibm.com ndmp_node_grp1 --appLimit 4

Note: If NDMP is not active on the specified NDMP node group, a message is displayed indicating that the configuration for prefetch for NDMP has been updated.

• To set a limit for the number of prefetching threads on file module, use the cfgndmpprefetch CLI command with the -numThreads option, as in the following example on the Storwize V7000 Unified file module.

cfgndmpprefetch –c ifs1isv.storage.tucson.ibm.com ndmp_node_grp1 --numThreads 100

Note: The value for the --numThreads option must be a positive integer, greater than 50 and less than or equal to 180. The default value is 100.

• To display NDMP backup prefetch status information, use the lsndmpprefetch CLI command using the -s or --status option, and optionally adding the -g option to limit display to the specified NDMP node group, as in the following example on the Storwize V7000 Unified file module.

lsndmpprefetch –c ifs1isv.storage.tucson.ibm.com –g ndmp_node_grp1 -s

Notes:

• IBM Tivoli Storage Manager backup / restore and NDMP backup / restore provide the same basic functionality of backing up or restoring file systems and the directories and files within the file systems. It is not recommended and not supported to have both Tivoli Storage Manager backup restore processing and NDMP backup restore processing being used on the same Storwize V7000 Unified system.

• NDMP backup are normally scheduled operations, which can be scheduled at a time when other activity, such as general purpose file serving, is low. If possible, it is recommended to perform NDMP backups during periods when other file serving activity is generally lower, perhaps late in the evening or early in the mornings.

• In case, the NDMP backup or restore processing significantly interferes with other Storwize V7000 Unified functions, such as network file serving (CIFS, NFS, FTP, HTTP) then consider increasing the processing energy and memory configuration of the Storwize V7000 file modules. Many Storwize V7000 Unified functions invoke the GPFS policy engine to evaluate a GPFS policy to determine the list of files to operate on. These include:

− Tivoli Storage Manager backup processing − Tivoli Storage Manager HSM processing − NDMP incremental backup processing − Asynchronous replication processing − The runpolicy CLI command and others

The GPFS policy engine scans the file system metadata to determine the files that match the criteria specified in the policy. This scan of the file system metadata can generate a significant amount of I/O to the storage systems to read all the file system metadata, especially for file systems containing very large number of files, such as 10s or 100s of millions of files. Therefore, it is recommended not to start all the Storwize V7000 Unified functions at exactly the same time, but instead be staggered over time.

Considerations for Symantec NetBackup DMA for Storwize V7000 Unified system NDMP backup Obtain either the IP address or host name for the file module to be used for this NDMP session.

• Host Name: Configure a DNS server with a common host name mapped to all of the IP addresses that are associated with the network group that is associated with the NDMP node group. If this host name is used, any of the file modules that are associated with the NDMP node group can be assigned based on a round robin IP address assignment from the DNS server.

• IP address: Submit the lsnwinterface CLI command using the -x option on the file module of the Storwize V7000 Unified system and choose an appropriate IP address or multiple IP addresses, if multiple backup policies are to be run simultaneously. This method is useful when multiple NDMP backup policies are used and you want to distribute the NDMP workload across file modules and ensure that the same file module will not be used for all of the backup policies that will be run from the DMA server.


22

Configure the Symantec NetBackup DMA server with the configuration parameters of the NDMP server for the file module that are available to perform NDMP services, including the user name and password associated with the NDMP node group. If a port other than 10000 was selected for the NDMP control port, then that control port's information needs to be configured on the DMA server.

Monitoring NDMP session on Storwize V7000 Unified system

Note: Read this information after configuring Symantec NetBackup NDMP configuration and staging appropriate Storwize V7000 Unified NDMP backup or restore. Refer to the “Symantec NetBackup NDMP Configuration” section for more information

• The lsndmpsession CLI command enables to monitor the NDMP session on Storwize V7000 Unified system. Use -n or -nodes option to view the NDMP sessions running on a specified file module or with the -g or --nodeGroupName option to view the NDMP sessions running on specified NDMP node groups.

Only file modules can be specified when using the -n or --nodes option. Multiple file modules and multiple node groups in a list must be separated with commas. If no file modules or node groups are specified, the output displays information for all of the file modules in the cluster. To determine the file modules that are running NDMP sessions for an NDMP node group, submit the following command that shows the file modules that have NDMP sessions running and the sessions that are running on the nodes:

lsndmpsession –c ifs1isv.storage.tucson.ibm.com -n mgmt001st001

Storwize V7000 Unified NDMP backup considerations

There are specific Storwize V7000 Unified NDMP environment variables, which are treated as parameters and can be passed to the NDMP server from data management applications performing NDMP backups. The following two parameters can be configured through data management applications.

• BACKUP_GROUP_NAME: This is the name of a backup group where all the backup directories within the backup group share the same Storwize V7000 Unified snapshot.

− Note 1: The way to set this environment variable is to have a line similar to the following

in the backup policy: SET BACKUP_GROUP_NAME=NDMP_EXISTING_snap1

− Note 2: If the BACKUP_GROUP_NAME parameter begins with NDMP_EXISTING, then

it is assumed that the Storwize V7000 Unified system is configured to use a snapshot, which has a name corresponding to this environment variable value. In this special case, it is also assumed that the user will delete the corresponding snapshot manually.

− Note 3: The maximum length of the backup group name is 32 characters (inclusive of a

possible NDMP_EXISTING).


65

• BACKUP_GROUP_EXPIRATION: This parameter helps to configure the amount of valid time that the snapshot is associated with BACKUP_GROUP_NAME. After the age of the snapshot has surpassed the expiration value, a new snapshot will be taken and all the new NDMP backup sessions associated with BACKUP_GROUP_NAME will use the new snapshot. This Storwize V7000 Unified NDMP parameter is very important to effectively schedule incremental or differential backup that has less than 1 hour incremental and differential backup expiration schedule time.

− Note 1: The way to set this environment variables is to have a line similar to the following

line in the backup policy:

SET BACKUP_GROUP_EXPIRATION = 1_DAY − Note 2: The following values are acceptable for this environment variable:

• 0_SEC … 60_SEC • 0_MIN … 60_MIN • 0_HOUR … 168_HOUR • 0_ DAY … 31_DAY • 0_MONTH … 12_MONTH

− Note 3: If no value is given for the expiration, the default will be 1 hour. − Note 4: If the user wants to ensure that a separate snapshot is taken for every directory,

then an expiration value of 0_SEC should be specified.

Symantec NetBackup NDMP restore

This section describes Symantec NetBackup NDMP restore feature.

Using Symantec NetBackup Direct Access Recovery (DAR) for NDMP restores

By default, Symantec NetBackup for NDMP is configured to use DAR when restoring files or directories. DAR is used differently for file restore when compared to directory restore, as follows:

• For each restore of files (not of directories), Symantec NetBackup automatically determines whether the use of DAR speeds up the restore. Symantec NetBackup uses DAR only when it results in a faster restore.

• For restore of directories, by default DAR is always used when restoring a subdirectory but never used when restoring the directory containing an entire image. For example, if /vol/vol0 contains the entire image, and /vol/vol0/dir1 is a subdirectory, DAR is used by default when restoring /vol/vol0/dir1. But it is not used when restoring /vol/vol0. For restore of subdirectories, Symantec NetBackup does not attempt to gauge the effectiveness of using DAR. Unless DAR is manually disabled, Symantec NetBackup always uses DAR when restoring subdirectories.

Summary The IBM Storwize V7000 Unified system is a virtualizing RAID storage system that supports both block protocols and file protocols. This unified system includes the IBM Storwize V7000 file module and the Storwize V7000 storage system.

The file module is a clustered system comprising two units that provide file systems for use by network-attached storage. The file module uses the Storwize V7000 storage system to provide the file module with volumes. Other volumes, which are block volumes, are provided on the SAN to be presented to hosts.

The Storwize V7000 Unified system has incorporated the NDMP technology and support the NDMP protocol version 4. Leveraging Symantec NetBackup NDMP backup support, the Storwize V7000 Unified data files can seamlessly back up to the tape devices and perform restore from the tape device.

This technical content is intended to be a reference guide for users who want to use Symantec NetBackup for backing up files (using NDMP protocol) that are incorporated on Storwize V7000 Unified system. This technical report is not meant to be an implementation or solution guide. For details on actual implementation or solution design, refer to the documentation provided in the “Resources” section of this technical paper.

Appendix A: Glossary

• IBM Storwize V7000 Unified system – Build on IBM high-performance computing experience, and designed to support both block and file storage protocols, Storwize V7000 Unified system provides the performance, high availability, single management interface, and functionality that are essential to address strategic storage requirements.

• Network Data Management Protocol (NDMP) – An industry standard protocol created to ease

the process of integrating backup and restore for NAS with data protection software, such as NetBackup. The NDMP is the data transfer protocol and one piece of the overall data protection solution. For more information about the NDMP protocol and the NDMP standards group, visit http://www.ndmp.org/info/faq.shtml.

• Two-way (or remote) Storwize V7000 Unified NDMP – An NDMP configuration supported by

Storwize V7000 Unified storage system. The two-way NDMP consists of an external data management application, such as Symantec NetBackup, running on a server external to the Storwize V7000 Unified storage system. The data management application has some form of storage hierarchy, such as a tape library that it manages for the storage of backup data.

• Three-way Storwize V7000 Unified NDMP – An NDMP configuration supported by Storwize

V7000 Unified storage system. In a three-way Storwize V7000 Unified NDMP configuration, an NDMP tape server is installed on a server external to the Storwize V7000 Unified storage system and separate from the system where Symantec NetBackup data management application is running.

• Symantec NetBackup – NDMP Data Management Application (DMA) used to backup Storwize

V7000 Unified data, using Storwize V7000 Unified NDMP technology.

• Direct access recovery (DAR) – Symantec NetBackup uses DAR to restore a directory or individual files from a backup image. DAR can greatly reduce the time it takes to restore files and directories. DAR is enabled by default (no configuration is required).
