As an option, DigiPath Production Software supports the use of a 
Redundant Array of Independent Disks (RAID) for mass storage 
of objects. A RAID device is an array of two or more relatively 
small, inexpensive SCSI hard disks organized to function as if 
they were a single, large disk drive. The hard disks are contained 
in an enclosure called the RAID cabinet and are managed by the 
RAID device controller. The RAID cabinet for the 100 GB RAID is 
capable of holding up to seven SCSI hard disks and the RAID 
cabinet for the 150 GB RAID is capable of holding up to ten SCSI 
hard disks. DigiPath Production Software supports a 
configuration using one or two RAID cabinets.

The device controller and management software, included with 
the RAID system, manage all internal aspects and operation of 
the device and make RAID operations transparent to the 
attached computer. From the computer and user viewpoints, the 
RAID device appears to be a single, large disk rather than 
several, small disks.
