RAID Overview |
|
Concept of RAID
RAID (Redundant
Array of Independent Disks) is an acronym first used in a 1988
paper by Berkeley researchers Patterson, Gibson and Katz. The
paper described array configuration and applications for
multiple inexpensive hard disks which in turn provided
redundancy and better access rates. When a RAID is created,
accessing multiple individual disks now act as if the array
were one large disk. It spreads data access out over these
multiple disks, thereby reducing the risk of losing all data
if one disk fails, and improving access time.
Why RAID?
Typically RAID
is used in large file servers, transaction of application
servers, where data accessibility is critical and fault
tolerance is required. Recently desktop users started to use
RAID for almost any application where massive storage or high
data transfers are required. RAID offers data production by
utilizing striping, mirroring or both.
