CHAPTER 5: RAID FUNCTIONS
5.1 O
Supports Windows XP, Windows Vista, and Windows 7.
PERATING SYSTEM
5.2 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.
RAID 10: RAID 10 combines the techniques used in RAID 0 and RAID 1.
5.3 HOW RAIDWORKS
RAID 0:
The controller “stripes” data across multiple drives in a RAID 0 array system. It breaks
up a large f ile in to sm al ler blo ck s a nd pe rf or ms dis k r ea ds a nd w rit es ac ro ss mu ltip le
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 and offers high bandwidth.
Features and Benefits
Drives: Minimum 2, and maximum is up to 6 or 8. Depending on the
platform.
Uses: Intended for non-critical data requiring high data throughput, or any
environment that does not require fault tolerance.
Benefits: provides increased data throughput, especially for large files. No
capacity loss penalty for parity.
Drawbacks: Does not deliver any fault tolerance. If any drive in the array
fails, all data is lost.
Fault Tolerance: No.

Block 1
Blo ck 3
Blo ck 5
Block 2
Blo ck 4
Blo ck 6
Page 23
A75MH / A55MH
RAID 1:
Every read and write is actually carried out in parallel 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 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.
Features and Benefits
Drives: Minimum 2, and maximum is 2.
Uses: RAID 1 is ideal for small databases or any other application that
requires fault tolerance and minimal capacity.
Benefits: Provides 100% data redundancy. Should one drive fail, the
controller switches to the other drive.
Drawbacks: Requires 2 drives for the storage space of one drive.
Performance is impaired during drive rebuilds.
Fault Tolerance: Yes.

Motherboard Manual
RAID 10:
RAID 1 drives can be stripped using RAID 0 techniques. Resulting in a RAID 10
solution for improved resiliency, performance and rebuild performance.
Features and Benefits
Drives: Minimum 4, and maximum is 6 or 8, depending on the platform.
Benefits: Optimizes for both fault tolerance and performance, allowing for
automatic redundancy. May be simultaneously used with other RAID levels
in an array, and allows for spare disks.
Drawbacks: Requires twice the available disk space for data redundancy,
the same as RAID level 1.
Fault Tolerance: Yes.
