Glossary

RAID 10

Dual-level array created by using two or more equal-sized RAID 1s to create a RAID 0. See also stripe, stripe set.

RAID 50

Dual-level array created by using two or more equal-sized RAID 5s. See also RAID 0, stripe, stripe size.

RAID signature

The area on each disk reserved for use by the RAID controller.

RAID volume

Concatenation of multiple RAID 0, RAID 1, or RAID 5 arrays.

rebuild

Background regeneration of redundant data (and/or parity) on a RAID 1, 5, 10 or 50.

reconfiguration

Process of expanding an array or migrating an array from one RAID type to another; changing the stripe size of a RAID 0, RAID 5, RAID 10 or RAID 50 or moving a logical device’s segments to other disks.

redundant

The ability of an array to maintain operability when one or more hardware failures occur. RAID 1, 5, 10 and 50 are 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
