Figure 2-3. Placement of the Service Processor
When a cabinet does not include a service processor, a filler panel covers the area of the
cabinet that the service processor normally occupies.
2.3 Understanding Component Numbering
Because of the large number of potential storage server configurations, 3PAR has standardized
component placement and internal cabling to simplify installation and maintenance. For this
reason, system components are placed in the cabinet according to the principles outlined in
this section and numbered according to their order and location in the cabinet.
2.3.1 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:
NOTE: For T800 Storage Servers, the service processor is located above the storage
server backplane, below the lowest drive chassis but above the upper battery tray.
Figure 2-5 illustrates service processor placement for an T800 storage server.
