Redundant Arrays of Independent Disks
<storage, architecture> (RAID. Originally "Redundant Arrays
of Inexpensive Disks") A project at the computer science
department of the University of California at Berkeley,
under the direction of Professor Katz, in conjunction with
Professor John Ousterhout and Professor David Patterson.
The project is reaching its culmination with the
implementation of a prototype disk array file server with a
capacity of 40 GBytes and a sustained bandwidth of 80
MBytes/second. The server is being interfaced to a 1 Gb/s
local area network. A new initiative, which is part of the
Sequoia 2000 Project, seeks to construct a geographically
distributed storage system spanning disk arrays and automated
libraries of optical disks and tapes. The project will
extend the interleaved storage techniques so successfully
applied to disks to tertiary storage devices. A key element
of the research will be to develop techniques for managing
latency in the I/O and network paths.
The original ("..Inexpensive..") term referred to the 3.5 and
5.25 inch disks used for the first RAID system but no longer
applies.
The following standard RAID specifications exist:
RAID 0 Non-redundant striped array
RAID 1 Mirrored arrays
RAID 2 Parallel array with ECC
RAID 3 Parallel array with parity
RAID 4 Striped array with parity
RAID 5 Striped array with rotating parity
