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 stripes. 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 mirrored array/mirroring.

RAID 10

Spanned array consisting of two or more equal-sized RAID 1 arrays. Provides redundancy by striping and mirroring. Mirroring provides data protection, and striping improves performance. See mirrored array/ mirroring, RAID 0.

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 Attached SCSI (SAS)

An evolution of parallel SCSI to a point-to-point serial interface

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.

single-level array

Array created from one or more segments. See volume, RAID 0, RAID 1, RAID 10.

snapshot

Instantaneous read-only copy of an array at a precise point in time.

stripe

Contiguous set of data distributed across all the disks in an array. A striped array distributes data evenly across all members in equal-sized sections called stripes.
