Drive Cabling
Topologies for the
E5460
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. The E5460
controller-drive tray can be connected to DE1600 drive trays, DE5600 drive trays,
DE6600 drive trays, or various combinations of those three models of drive tray.
WARNING (W15) Risk of bodily injury – An empty tray weighs approximately
56.7 kg (125 lb). Three persons are required to safel
y move an empty tray. If the tray
is populated with components, a mechanized lift is required to safely move the tray.
NOTE Install the E5460 controller-drive tray at the bottom of the cabinet so that the
cabinet does not become top-heavy. A top-heavy cabinet has a greater risk of falling
over.
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 drives in the storage array. The drive limit for
a controller-drive tray with InfiniBand host connections 240 drives. For all other
configurations, the limit is 384 drives. The drive limits includes drives installed in the
controller-drive tray.
