The figures in this section show representative cabling configurations. The configurations shown guarantee that redundant data paths exist between the controller-drive tray and all attached drive trays in a storage array. You can attach the controller-drive tray to the following drive trays:
You can attach the controller-drive tray to various combinations of all three drive tray models.
You must ensure that both controllers have access to all available drive trays by making sure that:
Except for the ESMs connected directly to the controllers, each ESM should have only a single connection to the ESM that follows it.
All controller-drive trays have a limit of 15 drive trays or a 384 drive-slot limit on the total number of drives in the storage array. In addition, DE1600 and DE5600 drive trays can be included in the storage array, as long as the same cabling pattern, connecting SAS expansion ports to SAS In ports, is followed.
One controller-drive tray and one DE1600 or DE5600 drive tray
One controller-drive tray and three DE1600 or DE5600 drive trays
One controller-drive tray and six or more DE1600 or DE5600 drive trays
One controller-drive tray and one DE6600 drive tray
One controller-drive tray and three DE6600 drive trays
One controller-drive tray and five DE6600 drive trays
