ARAID (Redundant Array of Inexpensive Disks) system can protect data in-

tegrity and dramatically improve performance compared to standalone drives.

Adaptec’s low-cost, high-performance PCI RAID adapters for entry-level and

midrange servers deliver real-time data recovery beyond tape backup for

uninterrupted data access.

Beneﬁts of Adaptec RAID adapters in fault tolerant computing include:

Support for multiple RAID levels 5, 1, 0, 0/1 over four arrays to meet speciﬁc

requirements

Leading edge PCI-to-PCI bridge design allows RAID adapters to transfer data

between the three SCSIchannels, RAID coprocessor and host system memory

at a burst rate of up to 133 MB/sec.

On-board RISC-based RAIDcoprocessor ofﬂoads all RAID 5 parity calcula-

tions from host server CPU.

Supports hot-swappable drives without interrupting data access.

Supports on-line hot-spare drives with auto rebuild.

Includes custom RAID software and Adaptec CI/O software for remote status

and performance monitoring of disk arrays and non-disk peripherals.

Unmatched scalability for additional performance and capacity.
