3.3.1 Cabinet Numbering
The InServ T-Class Storage Server 2M (40U) storage server cabinet is an EIA-standard rack that
accepts storage server components. Numbers for chassis bays are assigned:
■ beginning with 0.
■ from top to bottom.
Figure 3-4 illustrates numbering of chassis bays in a 3PAR cabinet.
Figure 3-4. Numbering of Chassis Bays in the Cabinet
A storage system can be housed in a single cabinet or multiple cabinets. When multiple
cabinets are required, the first cabinet (the controller node cabinet) holds the storage server
backplane populated with controller nodes. Any additional cabinets, or drive chassis cabinets,
hold the additional drive chassis that do not fit into the controller node cabinet.
