CHAPTER 4: NVIDIA RAID FUNCTIONS
4.1 OPERATION SYSTEM
z Support s Windows XP H om e/Prof essional Edition, and W indows 2000 Prof essional.
4.2 RAID ARRAYS
NVRAID suppor ts the following type s of RAID arra ys:
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 mirrori ng data.
RAID 0+1: RAID 0+1 combines the techniques used in RAID 0 and RAID 1.
4.3 HOW RAIDWORKS
RAID 0:
The controller “ stripes” data across multiple 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 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 h igh bandwidth .
Fea tures and Be nefits
Drives: Minimum 1, and m ax imum is up to 6 or 8. Depending on the
platform.
Uses: I ntended for non-crit ical data requiring high dat a throughput, or any
environment that does not require fault tolerance.
Benefits: provides increas ed dat a throughput, espec ially for large files. No
capac ity loss penalty f or parity.
Drawbacks: Does not deliver any fault toleranc e. If any drive in the array
fails, all data is lost.
Faul t Tolerance : No.

Bl o ck 5
Bl o ck 2
B lock 4
B lock 6
NF4 A M2 / NF4 4X AM2
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 d rive i s corrupted o r 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 media.
Fea tures and Be nefits
Drives: Minimum 2, and max imum is 2.
Uses: RAID 1 is ideal f or small dat abas es or any other applicat ion t hat
requires f ault tolerance and minimal capaci t y.
Benefits: Provides 100% data redundancy. Should one drive f ail, the
controller switches to the other dri ve.
Drawbacks: Requires 2 drives for the st orage space of one drive.
Performanc e is impaired during drive rebuilds.
Fault To le rance : Yes.

Motherboard Manual
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 platform.
- Benefits: Optimizes for both fault tolerance and performanc e, allowing f or
autom at ic redundancy. May be simultaneously used with other RAI D
levels in an array, and allows for spare disks.
- Drawbacks: Requires twice the available dis k s pac e f or data redundancy,
the same as RAID level 1.
