Back-End Cabling

An SCv2080 storage system may be installed with or without an expansion enclosure.

If you are installing an SCv2080 storage system with an expansion enclosure, you must connect the expansion enclosure to the back-end SAS ports on the storage system.

If you are installing an SCv2080 storage system without an expansion enclosure, you must interconnect back-end SAS ports on the storage system.

NOTE: A storage system with only one storage controller does not support back-end cabling.

Interconnecting Two Storage Controllers

When an SCv2080 with two storage controllers is deployed without expansion enclosures, the storage controllers must be interconnected using SAS cables.

NOTE: The left storage controller is storage controller 1 and the right storage controller is storage controller 2.

1.Connect a SAS cable between storage controller 1: port A and storage controller 2: port B.

2.Connect a SAS cable between storage controller 1: port B and storage controller 2: port A.
