72-Inch Cabinet Site Preparation and Installation Guide 3
Depending upon performance, capacity, and availability requirements, you can customize
the cabinet to meet your data storage needs. The cabinet contains two AC distribution
boxes and can support up to twelve command modules and drive modules. The command
module is a rackmount unit containing two array controllers, a battery, redundant cooling
fans and power supplies. Drive modules may contain up to fourteen drives, redundant fans
and power supplies, and either an array controller or Environmental Service Monitor
(ESM) board. See "Reference Documentation" on page 4 for information on the modules.
Figure 2 shows a typical configuration that includes five drive modules and one command
module mounted in the 72-inch rackmount cabinet. The cabinet is shipped with only the
bottom half filled to provide stability when shipping and moving the cabinet to the
installation site. The top half is filled with blank panels.
