Cisco SAN & Storage Consolidation Solutions

SAN and Storage Consolidation Improve:

Storage Utilization —provides a means of efficiently sharing storage resources across applications

Management Efficiency —provides a single infrastructure to manage and maintain

Resource Sharing —allows shared use of centralized resources such as Tape

Heterogeneous Storage —enables deployment of heterogeneous storage, operating systems and protocols onto single physical SAN

Consolidation Using Cisco’s Virtual SAN (VSAN) Technology

� Virtual fabrics support the need to consolidate numerous SAN islands

� Fabrics can be migrated from physical to virtual implementations

� New fabrics are provisioned through switch commands, not physical adds, moves, changes

� Fabrics provide basis for shared network-based storage services

SAN Island Consolidation: Three Approaches

� Switch linecard partitioning

� Island-level granularity

� No shared ISLs

� Interconnection, but no consolidation

VSAN-Based Roles—Just Like SAN Islands

� Enables deployment of VSANs that fit existingoperational models

� Network admin configures all platform-specific capabilities and VSAN allocations

� VSAN-admin(s) configure and manage their own VSANs

� The existing “role” definition is enhanced to include VSAN(s)

Inter-VSAN Routing (IVR):Sharing Resources Across VSANs

� Allows sharing of centralized storage services such as tape libraries and disks across VSANs—without merging separate fabrics (VSANs)

� Provides high fabric resiliency and VSAN-based manageabilityWorks for all Cisco MDS 9000 Switches with a software upgrade to SAN-OS 1.3(1)

Distributed, scaleable, and highly resilient architecture

Transparent to third-party switches

� Enables blade-per-VSANarchitecture for blade servers

CWDM – Coarse Wave Division Multiplexing

� 8-channel WDM at 20nm spacing (cf DWDM at <1nm spacing)– 1470, 1490, 1510, 1530, 1550, 1570, 1590, 1610nm

� Special “Colored” SFPs (or GBICs) used in FC Switches

� Muxing done in CWDM OADM (Optical Add/drop Multiplexer)– passive (unpowered) device – just mirrors and prisms

� 30dBm power budget (36dBm typical) on SM fiber– ~90km Point-to-point or ~40km ring

� Not EDFA amplifiable

• Benefits of Tape Backup over WAN:

– Centralized Tape Library

– Ubiquity & Economics of IP

• However, Tape Backup over WAN has issues:

– Sequential I/O reduces throughput

– Variable latency reduces the life of tape (shoe shine effect)

• FCIP Tape Acceleration overcomes the above limitations:

– Local MDS IPS Module proxies as a Tape Library

– Remote MDS IPS Module proxies as a Backup Server

Agenda






Defining Storage Virtualization (Forrester 2006)

► Technology that aggregates physically separate, heterogeneous storage resources into a single shared resource.

► Accomplished by creating logical abstractions of physical storage resources.
