Product Overview
Silicon Image’s SATARaid
TM
provides Serial ATA Software
RAID including Striping and Mirroring to enhance the
industry’s first proven PCI-to-SATA host controller product.
Two major challenges facing the storage industry today
are keeping pace with the increasing performance
demands of computer systems by improving disk I/O throughput and providing data accessibility in
the face of hard disk failures. With the SiI 3112 Serial ATA host controller and SATARaid, both of
these problems are solved.
RAID Striping greatly improves hard disk I/O performance by concurrently Striping data across mul-
tiple drives. RAID Mirroring enables users to enjoy the confidence of data availability regardless of
a single disk failure as data is simultaneously written to two drives.
Standard with SATARaid software is a Graphical User Interface (GUI) that provides easy-to-use configu-
rations for the different RAID Sets supported.
