CHAPTER 4: NVIDIA RAID FUNCTIONS

4.1 OPERAT ION SYSTEM

Supports Windows XP Home/Prof essional Edition, and Windows 2000 Professional.

4.2 RAID ARRAYS

NVRAID supports the f ollowing ty pes 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 0+1: RAID 0+1 combines the techniques used in RAID 0 and RAID 1.

Spanning (JB OD): JBOD provides a method for combining drives of different sizes in to

one large disk.

RAID 5: RAID 5 provides fault tolerance and better utilization of disk capacity.

4.3 HOW RAID WORKS

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.

Features and Benefits

 Drives: Minimum 1, and maximum is up to 6 or 8. Depending on the

platf orm.

 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 f or parity.

 Drawbacks: Does not deliver any fault tolerance. If any drive in the array

f ails, all data is lost.

 Fault Tolerance: No.
