5.4 Introduction for SiS180 RAID Function
The 180 S-ATA controller is a hybrid solution that combines two
independent SATA ports and one Ultra ATA port for support of up to two
Serial ATA (Serial ATA RAID) and two Ultra ATA (Ultra ATA RAID)
drives.
5.4-1 Serial/Ultra ATA RAID Interfaces
The Serial/Ultra ATA RAID is designed to provide a cost-effective, high
performance RAID solution that adds performance and/or reliability to PC
desktops and/or servers using Serial ATA/150, Ultra ATA/133, Ultra
ATA/100, Ultra ATA/66 hard disks.
Serial/Ultra ATA RAID function supports striping (RAID 0), mirroring
(RAID 1), striping + mirroring (RAID 0+1) and span (JBOD). Please note
that the function supports hard disk drives only and the 964 S-ATA controller
don’t support Striping + mirroring (Raid 0+1).
With striping, identical drives can read and write data in parallel to increase
performance. Mirroring increases read performance through load balancing
and elevator sorting while creating a complete backup of your files. Span
would increase the logic hard disk space.
Serial/Ultra ATA RAID striped arrays can double the sustained data transfer
rate of Serial ATA/150 and Ultra ATA/133 drives. Serial/Ultra ATA
RAID fully supports Serial ATA/150 and Ultra ATA/133 specification of
up to 150MB/sec per drive, depending on individual drive specifications.
5.5 Features
♦ The SiS 180 controller support two Serial ATA (Serial ATA RAID)
and two Ultra ATA (Ultra ATA RAID) drives.
♦ Support RAID function: RAID 0, RAID 1, JBOD and RAID 0+1.
(RAID 0+1 function can be used by 180 controller with all hard
drivers on it.)
♦ Support bootable disk except for RAID 0+1.
♦ Windows-based RAID Utility software tool (only support Windows
XP and 2000).
♦ BIOS Utility.
5.6 Support Operating Systems
Support Microsoft Windows 98/98SE/ME/2000 Professional and Server/
