Things to know - E2700 controller-drive tray
•
The controller-drive trays can connect to the DE1600 drive tray, the DE5600 drive tray, and the
DE6600 drive tray for expansion.
•
For any one controller-drive tray, you must not exceed the limit of 15 connected drive trays or the
limit for the total number of drive slots in the storage array, which is 192. In a E2760
configuration that consists solely of DE6600 drive trays, only 180 drives are supported. The drive
slot limit includes drive slots in the controller-drive tray.
Note:
Ensure that you do not turn on the power to the drive tray until this installation guide
instructs you to do so. For the correct procedure for turning on the power, see
Step 10 - Turning on
the power and checking for problems in a controller-drive tray configuration
on page 97.
