About the SCv3000 and SCv3020 Storage
System
The SCv3000 and SCv3020 storage system provides the central processing capabilities for the Storage Center Operating System (OS),
application software, and management of RAID storage.
The SCv3000 and SCv3020 storage system holds the physical drives that provide storage for the Storage Center. If additional storage is
needed, the
SCv3000 and SCv3020 supports SCv300 and SCv320 and SCv360 expansion enclosures.

Storage Center Hardware Components
The Storage Center described in this document consists of an SCv3000 and SCv3020 storage system, expansion enclosures, and
enterprise-class switches.
To allow for storage expansion, the SCv3000 and SCv3020 storage system supports multiple SCv300 and SCv320 and SCv360
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.
SCv3000 and SCv3020 Storage System
The SCv3000 and SCv3020 storage systems contain two redundant power supply/cooling fan modules, and two storage controllers with
multiple I/O ports. The I/O ports provide communication with host servers and expansion enclosures. The SCv3000 storage system
contains up to 16 3.5-inch drives and the SCv3020 storage system contains up to 30 2.5-inch drives.
The SCv3000 Series Storage Center supports up to 222 drives per Storage Center system. This total includes the drives in the storage
system chassis and the drives in the expansion enclosures. The SCv3000 and SCv3020 require a minimum of seven hard disk drives
(HDDs) or four solid-state drives (SSDs) installed in the storage system chassis or an expansion enclosure.
