Things to know - Cabling configurations for the E5560 controller-drive tray

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.

Note: The expansion connectors to the drive trays are always on the left side of the controllers from the rear view.

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.

Warning: (W10) Risk of bodily injury – Four or more persons are required to safely lift the component.
Note: The cabling pattern is independent of the physical location of the trays in the rack. If the storage array includes DE6600 drive trays, install those drive trays beginning from the bottom of the rack so that the rack does not become top-heavy. A top-heavy rack has a greater risk of falling over.
