The following figure shows cables for a storage array with the capacity for 384
drives, the maximum number. The storage array consists of a E5460 controller-drive
tray with five DE6600 drive trays and one DE5600 drive tray. The maximum capacity
can also be achieved by replacing the DE5600 drive tray in this example with two
DE1600 drive trays. When the E5460 controller-drive tray uses InfiniBand host
connections, the maximum supported number of drives is 240.
