Back-End Connections for an SCv2000/SCv2020 without
Expansion Enclosures
When you deploy an SCv2000/SCv2020 storage system without expansion enclosures, you must
interconnect the storage controllers using SAS cables.
NOTE: The top storage controller is storage controller 1 and the bottom storage controller is
storage controller 2.

Back-End Connections for an SCv2000/SCv2020 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.
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.
