Infrastructure SimplificationSome terminology

Consolidation– Leverage advances in storage density to consolidate many older

devices into fewer – or one – newer device.

Virtualization– Separate the logical representation of a resource from its physical

implementation – improving flexibility and simplifying management.

Reduced Cost and Improved Flexibilityfor Replication Services

Traditional SANReplication service API’s differ by vendor, making it difficult to integrate applicationsLower-cost disks offer primitive, or no replication services

SAN Volume ControllerCommon replication API, SAN-wide, that does not change as storage hardware changesReplication targets can be on lower-cost disks, reducing the overall cost of exploiting replication services

Performance – node pair

IOPs– Read (cache hit) 140,000 IO/s per node pair– Read (cache miss) 50,000– Write 20,000

Bandwidth– Read (cache hit) 1.5GB/s– Read (cache miss) 1.0GB/s– Write 400MB/s

Scales linearly with number of node pairs

IBM TotalStorage SAN File SystemAddresses file and data management issues

File, Data Management IssuesFile, Data Management Issues• File tasks must be done on each server• Difficult to migrate applications to other servers• Application Downtime required for FS changes• No single view/access to files or data• Cannot pool files based on Quality of Service

Volume, Storage Management IssuesVolume, Storage Management Issues• Server to storage logical connections are static• Server Downtime required to manage LUNs,

migrate volumes• Copy services are unique to each device• Difficult to pool volumes
