Storage Pools

You can divide the storage in multi-array groups into multi-array storage pools. For example, you might have a segregated storage pool for certain applications, users, or workloads. Arrays can be members of only one pool at a time. However, volumes assigned to storage pools can span multiple arrays.

The difference between groups and storage pools is that groups aggregate arrays for management, while storage pools aggregate arrays for capacity and performance. Storage pools provide automatic load balancing and migration capability, if all the other prerequisites for pools are met.
