6Gb/s SAS to SAS RAID Controller

The SAS to SAS 6Gb/s RAID controller provides 6Gb/s SAS host interface link to the host board on the server system. This RAID controller utilizes the same RAID kernel that has been field-proven in existing internal/external SATA/SAS RAID controller products, allowing to bring stable and reliable SAS RAID external subsystem. The SAS to SAS 6Gb/s RAID controller provides for 2U/3U/4U rack-mounted external storage chassis capable of accommodating up to 12/16/24 6.0-Gb/s, Serial-Attached SCSI (SAS) drives or 6.0-Gb/s Serial ATA (SATA) drives.

Optional Prouduct - Accessories

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-8068 box I/O port. You can use ARC-8028MB to fit ARC-8068 box I/O port in the standard ATX I/O-Slot found in a Rackmount Chassis.
