GigaRAID (IT8212) ATA RAID Controller USER'S MANUAL
Setup Array for RAID 1:
The GigaRAID (IT8212) ATA RAID Controller allows two drives to be setup as a RAID
1 (mirror) array or four drives as two arrays. The first mirrored array will be set as
array 0 and the second as array 1. RAID 1 is implemented as mirroring; a drive has
its data duplicated on the other different drive. Selecting RAID 1 can enhance read
performance and allow fault tolerance. A RAID 1 array can thoroughly backup your
files to prevent data loss.
Warning: Two hard drives that form a RAID 1 array have to be
!
attached as the same master or slave hard disks.
Setup Array for RAID 0+1:
A RAID 0+1 (mirror and stripe) array has to be formed by four hard drives. RAID 0+1
is implemented as a mirrored array whose segments are RAID 0 arrays so RAID 0+1
also has fault-tolerance capacity as RAID 1. It not only enhances hard disk access
performance but also backups data to prevent data loss. The formed array is
automatically set as array 0.
Setup Array for JBOD:
The GigaRAID (IT8212) ATA RAID Controller allows you to use two, three or four
hard drives to form a JBOD (Just a Bunch Of Disks) array as array 0. Although JBOD
doesn't offer other RAID functionality, it makes the hard disks appear to be a single
one by combining the drives into one larger logical one without any capacity loss.
