12Gb/s SAS to SAS RAID Storage Subsystem


The ARC-72xx RAID subsystem is a family of 8/12/16 12.0Gbps SAS hard drive ports depending upon the amount of storage required. The 12Gb/s SAS interface supports both 12Gb/s SAS disk drives for data-intensive applications and 6Gb/s SATA drives for low-cost bulk storage of reference data. The SAS to 12Gb/s SAS RAID controllers attach directly to SATA/SAS midplanes and increase capacity using one additional HD SFF-8644 external connector.

The ARC-72xx SAS to SAS RAID subsystem provides 12Gb/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 ARC-72xx provides 2U/3U rack-mounted external storage chassis capable of accommodating up to 8/12/16 12.0-Gb/s, Serial-Attached SCSI (SAS) drives or 6.0-Gb/s Serial ATA (SATA) drives.
