CHAPTER 4: RAID FUNCTIONS
4.1 OPERATION SYSTEM
z Supports Windows XP H om e/Prof essional Edition, and Windows 2000 Profess ional.
4.2 RAID ARRAYS
RAI D supports the f ollowing types of R AID arrays :
RAID 0: RAID 0 defines a disk striping scheme that improves disk read and write times for
RAID 1: RAID 1 defin es techniques for mirroring data.
RAID 0+1: RAID 0+1 combines the techniques used in RAID 0 and RAID 1.
RAID 5: RAID 5 provides fault tolerance and better utilization of disk capacity.
many applications.
4.3 HOW RAIDWORKS
RAID 0:
The controller “ stripes” data across multiple drives in a RA ID 0 array system. It breaks
up a large file into smaller blocks and performs disk reads and writes across multiple
drives in parallel. 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 time an d offers high b andwidth.
Fea tures and Be nefits
Drives: Minimum 1, and m ax imum is up t o 6 or 8. Depending on the
platform.
Uses: I ntended f or non-critical data requiring high data throughput, or any
environment that does not require f ault toleranc e.
Benefits: provides inc reas ed dat a throughput, especially for large f iles. No
capac ity loss penalty f or parity.
Drawbacks: Does not deliver any f ault tolerance. If any driv e in the array
fails, all dat a is lost.
Fa ult To le rance: No.

Motherboard Manual
RAID 1:
Every read and write is act ually carri ed out in parallel acros s 2 disk d rives in a RAID 1
array system. The mirrored (backup) co py of th e 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 hardw are 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
me d i a .
Fea tures and Be nefits
Drives: Minimum 2, and m ax imum is 2.
Uses: R AID 1 is ideal for small databases or any other application that
requires f ault tolerance and minimal capaci t y.
Benefits: Provides 100% data redundancy. Should one drive f ail, the
controller switches to the o ther drive.
Drawbacks: Requires 2 drives for the st orage spac e of one drive.
Performanc e is impaired during drive rebuilds.
Fa ult To le rance: Yes.

RAID 0+1:
RAID 0 drives can be mirrored using RAID 1 techniques. Resulting in a RAID 0+1
solution for improved performance plus resiliency.
Fea tures and Be nefits
Drives: Minimum 4, and m ax imum is 6 or 8, depending on t he platf orm.
Benefits: Optimizes for both fault toleranc e and performance, allowing for
autom at ic redundancy. May be simultaneously used with other R AID levels
in an array, and allows for spare disks.
Drawbacks: Requires twice the available dis k space for data redundancy,
the same as RAID level 1.
Fa ult To le rance: Yes.

Motherboard Manual
RAID 5:
RAID 5 stripes both data and parity information across three or more drives. It writes
data and parity blocks across all the drives in the array. Fault tolerance is maintained by
ensuring that the parity information for any given block of data is placed on a different
drive from those used to store the data itself.
Fea tures and Be nefits
Drives: Mini mu m 3 .
Uses: R AID 5 is recommended for transaction proces s ing and general
purpose s ervice.
Benefits: An ideal combination of good performance, good f ault toleranc e,
and high capacity and s t orage ef f ic iency.
Drawbacks: Individual block dat a transfer rate sam e as a single disk. W rit e
