TotalStorage SAN Volume Controller increase the flexibility of your storage
infrastructure by enabling changes to the physical storage with minimal or
no disruption to applications. Now with expanded support for many non-IBM
storage systems, including EMC, HP and HDS, SAN Volume Controller can
enable a tiered storage environment to better allow you to match the cost
of the storage to the value of your data. SAN Volume Controller combines
the capacity from multiple disk storage systems into a single storage pool,
which can be managed from a central point. This is simpler to manage and
helps increase utilization. It also allows you to apply advanced copy
services across storage systems from many different vendors to help further
simplify operations.
