Storage Virtualization: Key Virtualization
Features
Thin Provisioning
Satisfy provisioning requests but allocate
storage only when data is written
Dynamic
growth
Without thin provisioning,
pre-allocated space is reserved
whether the application uses it or not
With thin provisioning, applications can
grow dynamically, but only consume
space they are actually using
Real-time Compression
Improve capacity utilization across the
infrastructure
Value: Purchase only the storage you need
when you need it
Buy and maintain less storage
Compress active data up to 80% without
application performance degradation
For example, VMware ~75%,
Database ~80%, Exchange ~50%
Value: Store more data with less disk

Automatic
Relocation
with as little as 5% SSD
Value: Optimized performance at lower
overall cost
Hot-spots due to poor data layout.
Optimized performance and throughput.
Storage Virtualization: Key Management
Features
High Availability Configurations
Synchronous and asynchronous mirroring between sites
Real-time data mobility between sites complements
VMware vMotion and PowerHA Live Partition Mobility
Integrated management with practice support
Automated fail-back after repair
Value: Enable near-continuous data availability
Network
Application-Aware Copies
Integrated, instant copy for critical applications
Rapidly create clones for application testing
View inventory of application copies and instantly restore
Value: Virtually eliminate application downtime for backup
Practice Disaster Recovery Techniques
Practice application recovery procedures
Detect mirroring failure and automate failover
Value: Train staff and prove business continuity plans
work without disrupting applications
Storage Virtualization: 100% Availability across DCs
IBM Virtual Storage Center is both a
storage virtualization platform (System Storage SAN Volume Controller) and
storage virtualization management (Tivoli Storage Productivity Center)
IBM Virtual Storage Center provides simplified
management and non-disruptive data mobility
across heterogeneous tiers of storage
IBM Virtual Storage Center stretched-cluster
provides data access and mobility between two
physical datacenters
Use with
server hypervisor
virtual machine
mobility tools
enables transparent
migration of virtual
machines and their
corresponding
applications and
data over distance
