Understanding Component Numbering
Messages and Operator’s Guide InForm OS Version 2.3.1
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.
Table 5-1 describes the pattern for cabinet numbering in multi-cabinet storage systems and for
operating sites with multiple systems:
Figure 5-4 shows the location of controller node and drive chassis components for InServ F200
and F400 Storage Server controller node cabinets.
