CHAPTER 4: RAID FUNCTIONS
4.1 OPERATION SYSTEM
z Supports Windows XP Home/Prof es sional Edition, and Windows 2000 Prof es sional.
4.2 RAID ARRAYS
RAID supports the following types of RAID arrays:
RAID 0: RAID 0 defines a disk striping scheme that improves disk read and write times for
many applications.
RAID 1: RAID 1 defines techniques for mirroring data.
4.3 HOW RAIDWORKS
RAID 0:
The controller “ stripes” data across multiple drives in a RAID 0 array system. It b reaks
up a large file into smaller blocks and performs disk reads and writes across multiple
drives in parallel. The size of each b lock is determined by the stripe size parameter,
which you set during the creation of the RAID set based on the system environment. This
technique reduces overall disk access time and offers high bandwidth.
Fea tures and Be nefits
Drives: Minimum 1, and maximum is up to 6 or 8. Depending on the
platform.
Uses: Intended for non-critical data requiring high data throughput , or any
env ironment that does not require fault tolerance.
Benefits: prov ides inc reased data throughput, es pecially f or large f iles. N o
capacity loss penalty f or parity.
Drawbacks: Does not deliver any fault tolerance. If any drive in the array
f ails, all data is lost.
Fa ult Tolerance : No.

Bl ock 6

Motherboard Manual
RAID 1:
Every read and write is actually carried out in parallel acro ss 2 disk drives in a RAID 1
array system. The mirrored (backup) copy of the data can reside on the same disk or on
a second redundant drive in the array. RAID 1 provides a hot-standby copy of data if
the active volume or drive is corrupted or becomes unavailable because of a hardware
failure.
RAID techniques can be applied for high-availability solutions, or as a form of
automatic backup that eliminates tedious manual backups to more expensive and less
reliable media.
Fea tures and Be nefits
Drives: Minimum 2, and maximum is 2.
Uses: RAID 1 is ideal for small databases or any other application that
requires f ault tolerance and minimal capacity.
Benefits: Prov ides 100% data redundancy. Should one drive fail, the
controller switches to the other drive.
Drawbacks: Requires 2 drives for the storage space of one driv e.
Perf ormance is impaired during drive rebuilds.
Fault Tolerance : Yes.
