Coraid EtherDrive EM22 Storage Mirror Appliance

CORAID, Inc. announced the EtherDrive EM22 Storage Mirror appliance, an in-band network appliance providing block level LUN mirroring and partitioning. By enabling LUNs and RAID sets to be synchronously mirrored across multiple enterprise-wide storage chassis, the EM22 enables users to easily build fault tolerant storage systems with ‘No Single Point of Failure’ (NSPOF).

Responding to the market’s need for a highly available and affordable fault tolerant SAN, CORAID developed the EM22 Storage Mirror to provide seamless redundancy of EtherDrive storage appliances. "Upgrading an existing EtherDrive SAN to a fully redundant, fault tolerant SAN is as simple as adding the EM22 with an additional EtherDrive storage appliance," said James Kemp, CEO of CORAID. "Because our EtherDrive SAN solutions are so extremely affordable, customers can have a completely redundant, fault tolerant SAN at a fraction of the cost of a comparable iSCSI or Fibre Channel solution."

Enhancing the virtualization environment, the EtherDrive EM22 Storage Mirror provides a fault tolerant layer for SAN storage that is very complimentary to a VMware Infrastructure solution. Built upon the open ATA-over-Ethernet (AoE) lightweight SAN protocol, a single EM22 mirrors up to 255 AoE targets, an important factor for savvy users that manage sophisticated LUN groups that require fault tolerance.

EtherDrive SAN solutions are built upon the open ATA-over-Ethernet (AoE) lightweight storage area network protocol. AoE, an elegantly simple protocol, leverages the advantages of Ethernet to transport ATA disk commands without the burden of TCP/IP overhead. EtherDrive SAN solutions deliver affordable, fast SAN solutions that are simple to understand and easy to use.

The EtherDrive EM22 Storage Mirror is available for $1,995.
