Areca has added the SGPIO function in its SATA ll RAID controller......
ARC-1110/1120 (4/8-port PCI-X to SATA ll RAID Adapters)
The ARC-11X0 Serial ATA ll RAID host adapter is a high-performance PCI-X bus to SATA ll Disk Array host adapter. The controller can provide up to 4 or 8 SATA ll peripheral devices on a single 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.
The 4/8 port Serial ATA RAID Host adapter is low-profile PCI cards-ideal for 1U or 2U rack-mount system. It is used the same RAID kernel of its field-proven external RAID controller.
