Things to Know – E2600 Controller-Drive Tray
NOTICE!
On the E2600 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 maximum number of drive slots in the storage array is 96 (expandable to 192,
including the 12 or 24 drive slots in the controller-drive tray. Exceeding 96 (or 192) 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.
