4 Maintaining Control Modules
Different PS Series array models contain different control module types. The combination of chassis type,
control module pair, and drives determines the PS Series array model number.
Ideally, an array has two control modules (which must be of the same type) to avoid a single point of failure for
the array. However, only one functioning control module is required for array operation.
The control modules in a PS Series array contain the PS Series firmware which provides the Group Manager
GUI, the Command Line Reference, and all the array and storage management functions and features.
A PS-M4110 blade storage array includes one or two hot-swappable Type13 control modules.
Access PS-M4110 control modules by opening the array drawer. Figure 23 shows control modules between
groups of drives in the middle of an open array drawer.
