The path for the transfer of data between the controllers and the drives in the storage array.
8.2 Things to Know – E2600 Controller-Drive Tray
– The E2600 controller-drive tray supports the DE1600 drive tray for expansion.
– 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.

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.

NOTICE!
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.
