PS Series Storage Array Administration
PS Series storage arrays optimize resources by automating performance and network load balancing. Additionally, PS Series storage
arrays offer all-inclusive array management software, host software, and free firmware updates.
To manage PS Series storage arrays using Dell Storage Manager, the storage arrays must be running PS Series firmware version 7.0 or
later.

About Groups
A PS Series group is a fully functional iSCSI storage area network (SAN).
You create a group when you configure one or more PS Series arrays and connect them to an IP network. In this virtualized storage
system, the arrays become group members and share configuration data. A member belongs to a storage pool, and is configured with a
specific RAID policy. Each member cooperates with other members to enable the virtualization of disk storage, controllers, caches, and
network connections. Because the virtualization technology masks the underlying complexity of the storage configuration, client servers
see the group as a single entity, giving you a centralized view of the storage data.
The following figure shows and example of PS Series groups. Table 9. PS Series Group explains the callouts used in the figure.

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
One or more PS Series arrays represented as individual members within a pool to which it provides storage space to
utilize.
