1. An acronym for Redundant Array of Independent Disks,
a family of techniques for managing multiple disks
to provide desirable cost, data availability, and
performance characteristics to host environments.
2. A redundant Array of Independent Disks.
RAID Advisory Board
An organization of suppliers and users of storage
systems and related products whose goal is to foster
the understanding of storage system technology among
users, and to promote all aspects of storage technology
in the market.
RAID Array
A redundant Array of Independent Disks
RAID-related Product
Any
computer system storage product that implements RAID
technology as described in RAID Advisory Board publications
in some significant way. RAID-related products may
include disk controllers, disk systems, disks, software,
and test equipment.
Rebuilding
The regeneration and writing onto one or more replacement
disks of all of the data from a failed disk in a
RAID Level 1, 3, 4, 5, or 6 array. Rebuilding can
occur while applications are accessing data on the
array¡¦s virtual disks.
Redundancy
The
inclusion of extra components of a given type in a
system (beyond those required by the system to carry
out its function).
Redundant Array of Independent Disks
A disk array in which part of the physical storage
capacity is used to store redundant information
about user data stored on the remainder of the storage
capacity. The redundant information enables regeneration
of user data in the event that one of the array¡¦s
member disks or the access path to it fails.
Replacement Disk
A disk available for use as or used to replace
a failed member disk in a RAID array.
