Drive Chassis Numbering
Depending on the specific configuration, a storage system can include up to 64 drive chassis. A
drive chassis houses a single drive cage containing 10 drive bays. Each drive bay can
accommodate a single drive magazine holding four disks for a total of 40 hard drives per drive
cage. For a 10400, six DC4s can be installed in the base cabinet. For a 10800, two DC4s can
be installed in the base cabinet. Numbers for drive chassis are assigned beginning with 0, from
bottom to top.
Drive chassis are always placed above and below the node chassis and numbered according to
their position in relation to the node chassis, as shown in Figure 43 (page 44).
