SAN – Storage Virtualization

Dept 3VSAN

Dept 2VSANDept 1

VSAN

• VSANs created to provide isolation of fabric-wide services.

• Virtualization allows physical storage to be in its own VSANs, separate from the host VSANs.

• VSANs provide – Secure isolation of physical

storage– Easier configuration– Dynamic configuration of fabrics– Role-based access control

I/O

Not in Primary Data Path

= SAN Tap

Initiator <–> Target I/O

● SANTap is a protocol

– Between an MDS switch and a storage application appliance

● SANTap allows storage application appliances to get a copy of the SCSI writes between the servers and storage

● SANTap enables storage application appliances without impacting primary I/O

– That is, integrity, availability and performance of the Primary I/O is maintained

● Appliance does not reside in primary data path

Cisco – Data Backup Evolution

• Data movement over the SAN


• Snapshot backup

• Proxy host moves data

• Data movement over the LAN

BACKUP EVOLUTION

PERFORMANCE


SAN Based Serverless Backup

ConsPros

• Implementation of snapshot can add complexity

•Very large media servers for data movement

• Relatively good performance

• TCO is extremely high•Eliminates the data movement from

the application server

Benefit DescriptionCustomer Benefit

• No changes to existing backup environment• SSM Data Movement can be enabled w/ software

Investment Protection

• Each SSM delivers up to 16 Gbps throughput• SSM integrated in a HA MDS platform

Higher Performance & Reliability

• Offload I/O and CPU work from Media Servers to SSM• Reduce server admin & mgmt tasks

Lower TCO

Instead of Media Servers,MDS (w/ SSM) Moves DataFrom Disk to Tape

Reduction in latency of an I/O

Without FC Write Acceleration With FC Write Acceleration

● Requirements for FC Write Acceleration– Requires an ASM Module– Both Initiator and Target must be directly attached to the ASM Module

● Benefits of FC Write Acceleration– Improves response time for the storage app– Extended distance for DR and BC apps


Summary

● Cisco's Industry Leading Switching Platform● Modular Chassis● Multi-Protocol Line Card Modules● Intelligent Line cards

– In band Storage Virtualization– SANTap – Heterogenous Storage Solutions

● Storage Commoditized– NASB – Easing Data life cycle management– Additional intelligence
