There are two models of drive cages available for the InServ S-Class Storage Servers, DC2 and

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.
