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

14


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
