12Gb/s SAS External RAID Controller


ARC-8088-SAS
ARC-8088-2FC/4FC
ARC-8088-iSCSI

The ARC-8088 supports flexibility interface configuration; 8 x 12Gb/s SAS ports, 2/4 x 16Gb/s fibre channels or 2 x 10Gb/s iSCSI channel host and 4 x 12Gb/s SAS ports expander for performance and easy expansion. When used with 12Gb/s SAS expanders, the controller can provide up to (256) devices through one or more SAS JBODs, making it an ideal solution for enterprise class storage applications that called for maximum configuration flexibility.

The ARC-8088 RAID controller provides a rack-mounted external storage chassis capable of accommodating up to 12/16/24 12.0-Gb/s, Serial-Attached SCSI (SAS) drives or 6.0-Gb/s Serial ATA (SATA) drives. It provides three kinds of host interface link to the host board on the server system. The redundant controller model provides fault-tolerant links across separate host interface, while the single controller model provides a single, straight-through data path.

    An ATX I/O Shield is a small metal plate located at the back of each rackmount chassis that provide openings for different I/O ports of a motherboard.

    ARC-8028MB-Mounting Bracket for user to leverage the ATX I/O Shield position as ARC-8088 box I/O port. You can use ARC-8028MB to fit ARC-8088 box I/O port in the standard ATX I/O-Slot found in a Rackmount Chassis.
