The ARC-1170D 24-Ports SATA II RAID Controller is a high-performance PCI-X bus to SATA II Disk Array host adapter. When properly configured, the SATA host adapter can provide non-stop service with a high degree of fault tolerance through the use of RAID technology and advanced array management features. Intel IOP331 processor has integrated the RAID 6 engine inside. It offers Areca the advantage of reduced engineering and development costs, by having the new RAID6 function build-in and integrated part saves on component costs and internal PCI bandwidth. Intel emphasis on architectural commonality in IOPs allows Areca developers to capitalize on their existing code base.
