Intel RAID

Introducton

The motherboard comes wth the Intel RAID controller that allows you to congure

SATA hard drves as RAID sets.

SATA hard drves delver blsterng transfer speeds up to 6 Gb/s. Seral ATA uses long,

thn cables, makng t easer to connect your drve and mprovng the arow nsde your

PC. The most outstandng features are:

Supports 3 Gb/s or 6 Gb/s transfers wth CRC error checkng.

Supports Hot-plug-n-play feature.

Data handlng optmzatons ncludng tagged command queung, elevator seek and

packet chan command.

Intel

RAID controller oers RAID level 0 (Strpng), RAID level 1 (Mrrorng and Duplex-

ng), RAID level 5 (Block Interleaved Dstrbuted Party), RAID level 10 (A Strpe of Mr-

rors) , Intel

Rapd Storage Technology.

RAID 0 breaks the data nto blocks whch are wrtten to separate hard drves. Spread

ng the hard drve I/O load across ndependent channels greatly mproves I/O perfor-

mance.

RAID 1 provdes data redundancy by mrrorng data between the hard drves and pro

vdes enhanced read performance.

RAID 5 Provdes data strpng at the byte level and also strpe error correcton nforma

ton. Ths results n excellent performance and good fault tolerance. Level 5 s one of the

most popular mplementatons of RAID.

RAID 10 Not one of the orgnal RAID levels, multple RAID 1 mrrors are created, and a

RAID 0 strpe s created over these.

Intel

Rapd Storage Technology s the advanced ablty for two RAID volumes to share

the combned space of two hard drves beng used n unson.

Intel

Rapd Storage Technology utlzes RAID 1 functonalty to copy data from a des-

gnated Master drve to a desgnated Recovery drve. The sze of the Master drve must

be less than or equal to the sze of the Recovery drve. When a Recovery volume s

created, complete capacty of the Master drve wll be used as the Master volume. Only

one Recovery Volume can exst on a system. There are 2 methods of updatng the

data on the Master to the Recovery drve. They are Contnuous Update Polcy and On

Request Update Polcy.

Important

The least number of hard drves for RAID 0, RAID 1, Recovery or Matrx mode s 2. The

least number of hard drves for RAID 10 mode s 4. And the least number of hard drves

for RAID 5 mode s 3.

All the nformaton/ volumes/ pctures lsted n your system mght der from the llustra
