Overview
Congratulations on your selection of the Accusys 7630 (ACS-7630). The ACS-7630 is a
high-performance and extremely flexible RAID (Redundant Array of Independent/Inexpensive
Disks) controller. RAID is a storage technology used to improve the processing capabilities of
a storage system, providing a combination of reliability and performance.
The ACS-7630 is the ultimate approach to a flexible RAID solution. It can manage two
different RAID levels (0 and 5), with three IDE disks in a single RAID group. With a
cost-effective IDE approach, supporting Ultra DMA mode, the ACS-7630 strips data to three
disk drives simultaneously, and delivers optimized performance, comparable to more costly
SCSI based solutions.
Featuring intelligent online recovery, the ACS-7630 lets you hot swap a failed drive: data will
automatically be rebuilt to the new drive without any system down time. If a RAID 5 array
exists and one IDE disk drive fails, data is secured by the other drives, and an alarm sounds to
alert you. RAID 5 rebuild will proceed automatically (during power on) as soon as you lock the
disk carrier. If a RAID 0 array fails, there is no way to recover the data of the RAID system. You
should proceed by reconfiguring the new RAID with a new IDE disk.
The ACS-7630 Controller Box features a user-friendly rack design that lets you easily install
three drives. Each drive carrier supports a one-inch high 3.5-inch form factor drive. Security is
provided by a key-locking system that prevents unauthorized access to each disk drive.
