Logical representation of resources not constrained by physical limitations
► Enables user flexibility
► Centrally manage many resources as one
► Dynamically change and adjust across the infrastructure
► Create many virtual resources within single physical device
► Eliminates trapped capacities
IBM Virtualization
A comprehensive platform tohelp virtualize the infrastructure
What is Virtualization?

Traditional SAN Replication service API’s differ
by vendor, making it difficult to integrate applications
Replication targets must be the same expensive disk as the source
Lower-cost disks offer primitive, or no replication services
SAN Volume Controller Common replication API, SAN-
wide, that does not change as storage hardware changes
Replication targets can be on lower-cost disks, reducing the overall cost of exploiting replication services

Space-Efficient Virtual Disks (SEV)
SVC 4.3 introduces Space-Efficient Virtual Disks function, the SVC implementation of “thin provisioning”
Traditional (“fully allocated”) virtual disks use physical disk capacity for the entire capacity of a virtual disk even if it is not used
►Just like traditional disk systems
With SEV, SVC allocates and uses physical disk capacity when data is written
►Can significantly reduce amount of physical disk capacity needed
Available at no additional charge with SVC base virtualization license
Improve TCO +Improve Storage Utilisation

Virtual Disk Mirroring
SVC stores two copies of a virtual disk, usually on separate disk systems
SVC maintains both copies in sync and writes to both copies
If disk supporting one copy fails, SVC provides continuous data access by using other copy
►Copies are automatically resynchronized after repair
Intended to protect critical data against failure of a disk system or disk array
►A local high availability function, not a disaster recovery function
