Step 1: Remove the socket protection cap.
Step 2: Pull the lever toward direction A from the socket and then raise the
lever up to a 90-degree angle.
Step 3: Look for the white triangle on socket, and the gold triangle on
CPU should point towards this white triangle. The CPU will fit only
in the correct orientation.

CHAPTER 4: NVIDIA RAID FUNCTIONS
4.1 OPERATION SYSTEM
z Supports Windows XP Home/Prof essional Edition, and Windows 2000 Prof ess ional.
4.2 RAID ARRAYS
NVRAID supports the following ty pes of RAID arrays:
RAID 0: RAID 0 defines a disk striping scheme that improves disk read and write times for
RAID 1: RAID 1 defines techniques for mirroring data.
RAID 0+1: RAID 0+1 combines the techniques used in RAID 0 and RAID 1.
many applications.
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 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 f ault tolerance.
Benefits: prov ides increased data throughput, especially f or large files. No
capacity loss penalty for parity.
Drawbacks: Does not deliver any fault tolerance. If any drive in the array
f ails, all dat a is lost.
Faul t Tolerance : No.

Motherboard Manual
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 d ata can resid e on the s ame di sk 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 o f a hard ware 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 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 f ail, the
controller switches to the other drive.
Drawbacks: Requires 2 driv es for the storage space of one driv e.
Perf ormance is impaired during drive rebuilds.
Faul t Tolerance : Yes.

NF500-A2G/NF500 AM2
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 maximum is 6 or 8, depending on the platform.
Benefits: Optimizes for both fault tolerance and perf ormanc e, allowing for
automatic redundancy. May be simultaneously used with other RAID lev els
in an array, and allows for spare disks.
Drawbacks: Requires twice the available disk space for data redundancy,
the same as RAID level 1.
