Q
quick init
An array initialized using the Quick Init option is available immediately, with no on-
going background controller activity. All data written to an array that has been quick
initialized is protected.
R
RAID
Redundant Array of Independent Disks (alternative definition Redundant Array of
Inexpensive Disks).
RAID 0
A
single-level array
consisting of two or more equal-sized segments residing on
different disks. RAID 0 distributes data evenly across its respective drives in equal-
sized sections called
stripe
s. RAID 0 arrays are not redundant.
RAID 1
Single-level array consisting of two equal segments residing on two different drives.
Provides redundancy by storing identical copies on two drives. See also
mirrored
array/mirroring
.
RAID signature
The area on each disk reserved for use by the RAID controller.
RAID volume
Concatenates two or more arrays of the same type.
rebuild
Background regeneration of redundant data on a RAID 1.
redundant
The ability of an array to maintain operability when one or more hardware failures
occur. RAID 1 is redundant. In the event of a drive failure, redundant arrays can be
restored to normal operation by replacing the failed drive and rebuilding the array.
rescan
Process of updating the current screen to show all currently available resources.
S
Serial ATA (SATA)
A successor to ATA that uses a serial, instead of parallel, interface.
simple volume
A volume made up of disk space from a single disk. It can consist of a single region on
a disk or concatenated, multiple regions of the same disk.
