(12Gb/s SAS Expander Module)

ARC-8028 supports DataBolt™ Bandwidth Optimizer to buffer 6Gb/s data and then transfer it out to the host at 12Gb/s speeds in order to match the bandwidth between faster hosts and slower SAS or SATA devices. It also supports failover function for improving system reliability for today’s data center and storage subsystems.

The 12Gb/s SAS ARC-8028 expander module is designed with an integrated ARM Cortex-R4 processor for topology management functions such as discovery, enclosure and drive management, and LED management. The ARC-8028 expander module features three or four 12Gb/s SAS SFF-8644 ports. It is designed to fit into a stand-alone box and can be installed in a 5.25” mounting shell. The ARC-8028 is ideal for enclosure customers that want to support up to 24/32 channels 12Gb/s SAS or 6Gb/s and 3Gb/s SAS/SATA JBOD function units using SFF-8643 SAS cables. The ARC-8028 firmware has been included the failover to utilize the most up-to-date technology available, providing your system with reliable, high-quality performance. User can configure ARC-8028 redundant mode with multiple expander module using either RAID controllers or HBAs to achieve failover protection.
