E2600 Controller-Drive Tray Installation Guide 87
For example, if you are connecting controller A to the In connector on ESM A in drive tray 1, the label on the
controller end of the cable has this information:
CtA-Dch1, Dm1-ESM_A (left), In – Controller End
The label on the drive tray end of the cable has this information:
Dm1-ESM_A (left), In, CtrlA
10. If you are installing the controller-drive tray with two controllers, repeat step 2 through step 9 for the controller
in slot B in the controller-drive tray.
NOTE To connect cables for maximum redundancy, the cables attaching controller B must be connected to the
drive trays in the opposite tray order as for controller A. That is, the last drive tray in the chain from controller A
must be the first drive tray in the chain from controller B.
Things to Know – E2660 Controller-Drive Tray
On the E2660 controller-drive tray, each controller has a pair of levers with handles for removing the controller
from the controller-drive tray. One of these handles on each controller is located next to a host connector. The close
spacing between the handle and the host connector might make it difficult to remove a cable that is attached to the
host connector. If this problem occurs, use a flat-blade screwdriver to push in the release component on the cable
connector.
„
The E2660 controller-drive tray supports the DE6600 drive tray for expansion.
„
The maximum number of drive slots in the storage array is 180 drive slots, including up to 60 drive slots in the
controller-drive tray. Exceeding 180 drive slots makes the storage array invalid. The controllers cannot perform
operations that modify the configuration, such as creating new volumes.
„
Each controller has one dual-ported SAS expansion connector to connect to the drive trays.

NOTE To maintain data access in the event of the failure of a controller, an ESM, or a drive channel, you must
connect a drive tray or a string of drive trays to both drive channels on a redundant path pair.
