Introducton
The manboard 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.

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.

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.

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
