About the SCv2000/SCv2020 Storage System
The SCv2000/SCv2020 storage system provides the central processing capabilities for the Storage Center Operating System (OS)
and management of RAID storage.
The SCv2000/SCv2020 storage system holds the physical drives that provide storage for the Storage Center. If additional storage
is needed, the
SCv2000/SCv2020 also supports SC100/SC120 expansion enclosures.
Storage Center Hardware Components
The Storage Center described in this document consists of an SCv2000 or SCv2020 storage system, enterprise-class switches, and
expansion enclosures.
To allow for storage expansion, the SCv2000/SCv2020 storage system supports multiple SC100/SC120 expansion enclosures. A
single-controller system does not support expansion enclosures.
NOTE: The cabling between the storage system, switches, and host servers is referred to as front‐end connectivity. The
cabling between the storage system and expansion enclosures is referred to as back-end connectivity.
SCv2000/SCv2020 Storage System
The SCv2000 and SCv2020 are 2U storage systems with built-in storage. The SCv2000 is a 2U storage system that supports a
minimum of 7 and a maximum of 12 internal 3.5–inch hot-swappable SAS hard drives installed in a four-column, three-row
configuration. The
SCv2020 is a 2U storage system that supports up to 24 internal 2.5–inch hot-swappable SAS hard drives
installed vertically side-by-side.
The SCv2000/SCv2020 storage system contains two redundant power supply/cooling fan modules and two storage controllers
with multiple I/O ports that provide communication with servers and expansion enclosures.
Switches
Dell offers enterprise-class switches as part of the total Storage Center solution.
The SCv2000 storage system supports Fibre Channel (FC) and Ethernet switches, which provide robust connectivity to servers
and allow for the use of redundant transport paths. Fibre Channel (FC) or Ethernet switches can provide connectivity to a remote
Storage Center to allow for replication of data. In addition, Ethernet switches provide connectivity to a management network to
allow configuration, administration, and management of the Storage Center.
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.
