ATI SATA RAID Setup Guide
Two major challenges facing the storage industry today are (1): keep pace with
increasing performance demands of computer systems by improving disk I/O
throughput, and (2): provide data accessibility in the event of hard disk failure.
To meet these two challenges, ATI south bridge SB450 supports four SATA ports and
incorporates Silicon Image
’s SiI 3112 Serial ATA host controller, together with Silicon
Image ’s Serial ATA RAID Management Software (SATARaid™).
SATARaid software provides support for RAID Striping and RAID Mirroring. RAID
Striping greatly improves hard disk I/O performance by concurrently striping data
across multiple drives. RAID Mirroring makes sure data is not lost if a drive fails as
data is simultaneously written to two drives. Drives configured for RAID Striping are
said to form a RAID 0 set, while drives configured for RAID Mirroring are said to form
a RAID 1 set.
The SATARaid software includes a Graphical User Interface (GUI) that provides
continuous monitoring of the RAID set(s) supported.
