Drive channel redundancy for the E5700 controller shelves
Learn the physical features of the E5700 controller shelves that support drive cabling to minimize the
risk of losing access to data.
Controller shelves
Each controller in an E5724, EF570, or E5760 controller shelf have two drive ports. On each
controller, the two drive ports connect to the same drive channel (SAS domain). The E5700 only
supports two controller configurations, the drive channel on controller A and the drive channel on
controller B form a redundant pair.
Note:
To maintain data access in the event of the failure of a controller, an ESM/IOM, or a drive
channel, each drive enclosure/tray must have a direct connection or an indirect connection (through
other drive enclosures/trays) to at least one drive port on each controller.
The following figure shows the drive ports (SAS expansion ports) for the E5724 controller shelf. The
controllers occupy the top half of each shelf. The drive ports are near the center of each controller.
