Serial ATA RAID Quick User’s Guide
1
Introduction
The 964 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.
Specifications are as follows:
Serial ATA Interface
Serial ATA (SATA) is the latest generation of the ATA interface. SATA hard
drives deliver blistering transfer speeds of up to 150MB/sec. Serial ATA
uses long, thin cables, making it easier to connect your drive and improving
the airflow inside your PC.
♦
Supports 150 MB/s transfers with CRC error checking
♦
Large LBA support for drives over 137 GB
♦
Data handling optimizations including tagged command queuing, elevator seek
and packet chain command
Ultra ATA Interface
♦
Standard ATA/IDE interface
♦
Supports Ultra ATA/133, Ultra ATA/100, and Ultra ATA/66 drives
♦
Supports CRC error checking for Ultra ATA drives
♦
Separate timing control for two devices attached to one ATA channel
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), st mirroring (RAID 0+1) and span (JBOD).
Please note that the
function supports
hard disk drives
only.
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.
