CHAPTER 4: RAID FUNCTIONS
4.1 OPERATION SYSTEM
Supports Windows XP H ome/Professional Edition, and Windows 2000 Professional.
4.2 RAID ARRAYS
RAID supports the f ollowing types of RAI D arrays:
RAID 0: RAID 0 defines a disk striping scheme that improves disk read and write times for
The controller “stri pes” dat a across mu ltiple drives in a RAID 0 array system. It breaks
up a large file into smaller blocks and performs disk reads and writes across multiple
drives in p arallel. The size of each block 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 ti me and offers hi gh bandwidth.
Fea tures and Be nefits
Drives: Minimum 1, and max imum is up to 6 or 8. Depending on the
platform.
Uses: I ntended for non-critic al data requiring high data throughput, or any
env ironment that does not require f ault tolerance.
Benefits: prov ides increased data throughput, especially f or large files. No
capacity loss penalty for parity.
Drawbacks: D oes not deliver any fault tolerance. If any drive in t he array
f ails, all data is lost.
Fault Tolerance : No.

Motherboard Manual
RAID 1:
Every read and write is actually carri ed out in p arallel across 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 volu me or drive i s corrupted or b ecomes 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: R AID 1 is ideal for small databases or any other application t hat
requires f ault tolerance and minimal capacity.
Benefits: Prov ides 100% data redundancy. Should one drive f ail, the
controller switches to t he ot her drive.
Drawbacks: Requires 2 driv es for t he storage space of one driv e.
Perf ormance is impaired during driv e rebuilds.
Faul t Tolerance: Yes.
