Pools

A storage pool confines data to a subset of the arrays in a group. A storage pool is a logical container that contains one or more member arrays in which volumes reside. The system stripes and automatically rebalances data of resident volumes over the members across the pool. Storage pools dictate physical locality and striping characteristics. A member array can only be a part of one storage pool. Note the following:

• Volumes and their respective snapshots and clones reside within a pool and are tied to a specific pool.

  Volumes are also referred to as logical units (LUNs). On an array, LUNs are exposed as volumes.

• You can migrate (move) volumes between different pools.
• Volume collections are not tied to pools and can contain volumes that reside in different pools.

Use single-array pools under the following conditions:

• Fault isolation is a priority
• Linux hosts, or any hosts that do not have a supported HPE Storage Connection Manager available, can access the arrays

Consider using multi-array pools under the following conditions:

• Scaling performance and capacity, as well as consolidating management, are priorities
• Windows and ESX hosts that have a supported Connection Manager available can access the arrays
