ATI SATA RAID Setup Guide
Chapter 4. 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 im
proving disk I/O throughput, and (2): provide data accessibility in the event of
hard disk failure.
To meet these two challenges, ATI south bridge SB400 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 con
currently 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.
