About Volumes
Volumes provide the storage allocation structure within the PS Series group.
To access storage in a PS Series group, you allocate portions of a storage pool to volumes. You can create a volume on a single group
member or one that spans multiple group members. You assign each volume a name, size, and a storage pool. The group
automatically load balances volume data across pool members.
Figure 5. PS Series Volumes depicts volumes in a PS Series group. Table 6. PS Series Volumes explains the callouts used in the
gure.

Callout Description
1 PS Series group
Storage area network (SAN) comprising one or more PS Series arrays connected to an IP network. Arrays are
high-performance (physical) block storage devices.
2 PS Series members
Each PS Series array is a member in the group and is assigned to a storage pool.
3 PS Series storage pools
Containers for storage resources (disk space, processing power, and network bandwidth).
4 PS Series single-member pool
A PS Series array represented as a member within a pool to which it is assigned.
5 PS Series multimember pool
Multiple PS Series arrays represented as individual members within a pool to which it is assigned.
