Drive Channel
Redundancy for
the E5412
Controller-Drive
Tray and the
E5424
Controller-Drive
Tray
Each controller in a E5412 or a E5424 has one drive port. When a controller-drive
tray has two controllers, the drive port on controller A and the drive port on controller
B form a redundant pair. The following figure shows the drive ports on a
dual-controller configuration.
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
ports on a dual-controller configuration.
