Drive Chassis Numbering
Depending on the specific configuration, a storage system can include up to 64 drive chassis. A
drive chassis houses two drive cages where each contains five drive bays. Each drive bay can
accommodate a single drive magazine holding four disks for a total of 20 disks per drive cage
and 40 disks per drive chassis.
Numbers for drive chassis are assigned beginning with 0, from bottom to top, beginning with the
drive chassis directly above the storage system backplane.
