What is Virtualization?
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 to
help virtualize the infrastructure

Why Storage Virtualization?
“Server virtualization is about savings, but storage
virtualization is … more about flexibility.”
John Murphy, CEO of MYRA Systems Corp
Top Storage Virtualization Business Drivers
Reduce capital costs (including real estate)
Implement tiered storage
Control rapid capacity growth
Dynamic resource flexibility
Improve utilization rates
Disaster recovery and data protection
Reduce data center complexity

 Disk Array independant
mirroring
 Lower Secondary Array Cost
Traditional SAN
 Replication service API’s differ
SAN Volume Controller
 Common replication API, SAN-
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
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
Improve TCO +
Improve Storage Utilisation
 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

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
SAN Volume Controller
►A
local high availability function, not a
disaster recovery function
