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.
