Increasing storage availability - Reverse Cabling

In order to provide higher availability, the controller enclosure is connected to the drive enclosure via reverse cabling. The connection of the primary path is implemented in ascending order while the secondary path is connected in descending order, as shown in the following figure.

Reverse Cabling

Benefits

  • Drive enclosure access is ensured even when a DE failure occurs.
  • Availability for data transfer paths between controllers and drives is better than older models.
