Overview
The IBM ATA 133 RAID controller is a short PCI adapter card that provides two IDE
channels with ATA 133 capability. IBM ATA 133 provides a simple and cost-effective
way to improve the performance and reliability of your storage subsystems. The RAID
controller offers high transfer rates, and fault-tolerant data redundancy during high
performance applications by using low-cost Ultra ATA drives in desktops, workstations,
or low-end servers.
You can connect from one to four drives to this card using ATA 100/133 cables (Ultra
ATA drives need special 80-pin IDE cables) and configure these drives using a simple
setup menu embedded in the controller BIOS. The card supports the following drive
modes: programmable input/output (PIO) 0-4, direct memory address (DMA) 0-2, and
Ultra DMA 0-6.
In addition, the card supports RAID levels 0, 1, and 10. You can use striping (RAID 0) to
improve performance or mirroring (RAID 1) to improve data security. RAID 10 provides
both RAID 1 (disk mirroring) and RAID 0 (data striping). This manual describes RAID
features, RAID levels, hardware installation, operating system installation, and technical
assistance.
