Back-End Connections for an SCv2000/SCv2020 Storage System

Without Expansion Enclosures

When you deploy an SCv2000/SCv2020 storage system without expansion enclosures, you must interconnect the storage

controllers using SAS cables. A single controller system should not connect a back-end SAS cable from port A to port B.

NOTE: The top storage controller is storage controller 1 and the bottom storage controller is storage controller 2.

The following table describes the back-end SAS connections for an SCv2000/SCv2020 storage system without expansion

enclosures.

Back-End Connections for an SCv2000/SCv2020 Storage System

With Expansion Enclosures

The SCv2000/SCv2020 storage system supports a total of 168 disks per Storage Center system.

• The SCv2000 supports up to thirteen SC100 expansion enclosures, up to six SC120 expansion enclosures, or any combination of

SC100/SC120 expansion enclosures as long as the total disk count of the system does not exceed 168.

• The SCv2020 supports up to twelve SC100 expansion enclosures, up to six SC120 expansion enclosures, or any combination of

SC100/SC120 expansion enclosures as long as the total disk count of the system does not exceed 168 disks.

NOTE: The SCv2000/SCv2020 storage system does not support the SC180.

The following sections show common cabling between the SCv2000/SCv2020 and SC100/SC120 expansion enclosures. Locate the

scenario that most closely matches the Storage Center that you are configuring and follow the instructions, modifying them as

necessary.
