SiIicon 3114 SATA RAID (optional)
1. Introduction
Silicon Image’s SATARAID5
TM
software provides Serial ATA RAID 0 (Striping), RAID
1 (Mirroring), RAID 5 (Parity RAID), RAID 10 (Striping and Mirroring), and JBOD
(just a bunch of disks) functionality to enhance the industry’s leading PCI-to-SATA
host controller products. Two major challenges facing the storage industry today
are keeping pace with the increasing performance demands of computer sys-
tems by improving disk I/O throughput and providing data accessibility in the face
of hard disk failures while utilizing full disk capacity. With SiIicon Image Serial ATA
host controller and SATARAID5, both of these problems are solved.
SATARAID5 software provides a Graphical User Interface (GUI) for easy-to-use
configurations of the RAID Groups.
