2.2.3 Drive Cage Numbering
There are two models of drive cages available for the InServ S-Class Storage Servers, DC2 and
DC4. Depending on the specific configuration, a storage server may contain up 64 drive cages.
The DC2 and DC4 drive cages contain ten drive bays and each drive bay accommodates a single
drive magazine holding four disks. A single InServ S-Class Storage Server can contain both DC2
and DC4 drive cages.
NOTE: Figure 2-4 shows a sample system and may not match your particular
storage server configuration.
