Sans Digital EliteRAID 2U Rackmount 8 Bay SATA to USB / eSATA Hardware RAID 6


SKU: ER208UT+B Category:


Product Overview

The EliteRAID ER208UT+B is a 2U 8-bay rackmount with USB 2.0 / eSATA interfaces (up to 200MB/s), and embedded hardware RAID 6 engine. The hardware RAID feature offloads complex RAID calculations from the client’s operating system to the RAID engine, which increases the overall read/write performance and eliminates OS compatibility issues. The built-in Web GUI management interface and event notification with SMTP E-mail and SNMP trap allow administrators to monitor unit status remotely via web browser without the need for additional software. In addition to RAID 5, Mirroring (RAID 1) and Striping (RAID 0), the ER208UT+B also supports RAID 6 to protect stored data against up to two hard drive failures. JBOD is supported via port multiplier and allows drives to be accessed individually. Utilizing both SATA I and SATA II drive interfaces, the ER208UT+B is guaranteed to achieve the high performance with fail-safe file protection.

The use of enterprise hard drives is recommended when in use with any RAID controller applications. Standard desktop or green desktop drive may not be supported and may compromise RAID system stability and performance.
