Configuring Partner Groups
Sun StorEdge T3 and T3+ arrays can be interconnected in partner groups to form a
redundant and larger storage system.
Note – The terms partner group and enterprise configuration refer to the same type of
configuration and are used interchangeably in this document.
Note – Partner groups are not supported in Sun Cluster 2.2 configurations.
This chapter describes how to configure array partner groups, and it includes the
following sections:

Understanding Partner Groups
In a partner group, there is a master controller unit and an alternate master controller
unit. The master controller unit is the array positioned at the bottom of an array
stack in either a rackmounted or tabletop installation. The alternate master controller
unit is positioned on top of the master controller unit. Array units are connected
using the interconnect cards and interconnect cables. A partner group is shown in
