1.5 RAID Concepts
The basic idea of RAID (Redundant Array of Independent Disks) is to combine multiple
inexpensive disk drives into an array of disk drives to obtain performance, capacity and
reliability that exceeds that of a single large drive. The array of drives appears to the
host computer as a single logical drive.
From (PC) host controller, each logical device (RAID volume) controlled by the RAID box
acts just the same as single regular hard disk although a RAID volume generally consists
of more than one hard disk drives.
The RAID box provides several RAID Modes as described below.

NOTE: In GUI Only Mode, the RAID Mode is configured only in the
SteelVine Manager GUI.
