CHAPTER 6: NVIDIA RAID FUNCTIONS

6.1 OPERATION SYSTEM

Supports Windows XP Home/Professional Edition, and Windows 2000

Professional.

6.2 RAID ARRAYS

NVRAID supports the following types of RAID arrays:

RAID 0: R AID 0 defines a disk striping scheme that improves disk read and writes times for many applications.

RAID 1: R AID 1 defines techniques for mirroring data. RAID 0+ 1 : RAID 0+1 combines the techniques used in R AID 0 and RAID 1.

S p a nn i ng (JB O D): JB OD provides a m ethod for combining drives of different

sizes in to one large disk.

6.3 HOW RAID WORKS

RAID 0:

Th e co n t r oller “ s trip es ” d ata acro s s multiple drives in a RAID 0 array

sy s tem . It break s u p a l arg e fil e i n to smaller blocks and per forms di sk reads

and writes across multiple drives in parallel . The s i ze o f each blo ck i s

determined by the strip size parameter, which you set during t he creat ion of the

RAID set based on the system environment. T his technique reduces

ov eral l d is k acces s time and offers high bandwidth.

Fea tures and Be nefits

- Drives: Minimum 1, and m aximum is up to 6 or 8. Depending on t he

platform.

- Uses: I ntended f or non-crit ical data requiring high data throughput, or any

env ironm ent 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 data is lost .

- Fa ult Tolerance: No.

Blo ck 1 Block 3 Block 5

Blo ck 2 Block 4 Block 6

N4SIE-A7

RAID 1:

Every read and write is actually carried out in paral lel across 2 disk drives in a RAID 1 array system. T he mirrored (backup) copy o f 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 i f the active

volume or drive is corrupted or becomes unavailable because o f a hardw are

failure. RAID techni ques 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 maximum is 2.

- Uses: RAID 1 is ideal f or small databases or any other application that

requires f ault tolerance and minimal c apacity.

- Benefits: Prov ides 100% data redundancy. Should one driv e fail, the

controller switches to t he other drive.

- Drawbacks: Requires 2 driv es f or the storage space of one driv e.

Perf orm ance is impaired during driv e rebuilds.

- Fault Tolerance : Yes.

Blo ck 1 Block 2 Block 3

S p anning (JBOD):

JBO D s tan d s for “ Ju s t a Bu n ch o f Di s k s ”. Each dr i v e i s acces s ed as if it w ere on a standard S CS I host bus

adap t er. Thi s is u s eful w hen a single drive configur ation i s

needed, but it offers no speed improvement or fault tolerance.

Fea tures and Be nefits

- Uses: JBOD works best if you hav e odd sized driv es and y ou want to

combine them to mak e one big drive.

- Benefits: J BOD prov ides t he ability to com bine odd size driv es us ing all of

the capacity of the driv es .

- Drawbacks: Decreases performance because of the difficulty in us ing

driv es c oncurrently.

- Fa ult Tolerance: Yes.

CHAPTER 7: W ARPSPEEDER™

7.1 INTRO DUCTION

[WarpSpeeder™], a new powerful control utility, features three user-friendly functions including Overclock Manager, Overvoltage

Manager, and Hardware Monitor.

With the Overclock Manager, users can easily adjust the frequency they prefer or they can get the best CPU performance with just one click. The

Overvoltage Manager, on the other hand, helps to power up CPU core voltage and Memory voltage. The cool Hardware Monitor smartly indicates

the temperatures, voltage and CPU fan speed as well as the chipset information. Also, in the About panel, you can get detail descriptions about

BIOS model and chipsets. In addition, the frequency status of CPU, memory, AGP and PCI along with the CPU speed are synchronically

shown on our main panel. Moreover, to protect users' computer systems if the setting is not

appropriate when testing and results in system fail or hang, [WarpSpeeder™] technology assures the system stability by automatically

rebooting the computer and then restart to a speed that is either the original system speed or a suitable one.
