Expansion Enclosures
Expansion enclosures allow the data storage capabilities of the SCv2000/SCv2020 storage system to be
expanded beyond the 12 or 24 internal disks in the storage system chassis.
The SCv2000/SCv2020 storage system supports a total of 168 disks per Storage Center system. This total
includes the disks in the storage system chassis and the disks in the SC100/SC120 expansion enclosures.
• 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.
Storage Center Architecture Options
A Storage Center with an SCv2000/SCv2020 storage system can be deployed in the following
configurations:
• An SCv2000/SCv2020 storage system deployed without SC100/SC120 expansion enclosures.
Figure 1. SCv2000/SCv2020 without Expansion Enclosures
• An SCv2000/SCv2020 storage system deployed 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.

Storage Center Replication
Storage Center sites can be collocated or remotely connected and data can be replicated between sites.
Storage Center replication can duplicate volume data to another site in support of a disaster recovery
