Expansion Enclosures
An SCv2000/SCv2020 storage system supports multiple SC100/SC120 expansion enclosures. The
expansion enclosures allow the data storage capabilities of the SCv2000/SCv2020 to be expanded
beyond the
12 or 24 internal drives in the storage system chassis.
The SCv2000/SCv2020 storage system supports a total of 168 drives per Storage Center system. This
total includes the drives in the SCv2000/SCv2020 storage system chassis and the drives in SC100/SC120
expansion enclosures chassis.
• 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 drive
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 drive
count of the system does not exceed 168.
Storage Center Architecture Options
A Storage Center with an SCv2000/SCv2020 storage system can be deployed in two configurations:
• An SCv2000/SCv2020 storage system without SC100/SC120 expansion enclosures.
Figure 1. SCv2000/SCv2020 without Expansion Enclosures
• An SCv2000/SCv2020 storage system with one or more SC100/SC120 expansion enclosures.
NOTE: A storage system with a single storage controller cannot be deployed with expansion
enclosures. The storage system must have dual storage controllers to deploy expansion
enclosures.
