12-bays 12Gb/s SAS to SAS Desktop RAID Subsystem

The ARC-8042-12 SAS to SAS desktop RAID subsystem raises the standard to higher performance levels with several enhancements including new high performance 1.2GHz dual core ROC processor, a DDR3-1866 memory architecture and 12Gb/s SAS technology. The ARC-8042-12 includes 2GB DDR3-1866 and ECC SDRAM.

The ARC-8042-12 SAS to SAS desktop 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-8042-12 provides external storage chassis capable of accommodating up to 12 12.0-Gb/s Serial-Attached SCSI (SAS) drives or 6.0-Gb/s Serial ATA (SATA) drives.
