Coraid ships AoE-based SAN arrays

By Kevin Komiega

-- Coraid has introduced new versions of its ATA-over-Ethernet (AoE)-based EtherDrive SRX-Series storage arrays with support for 10 Gigabit Ethernet (10GbE) connections and SATA, SAS, and solid-state disk (SSD) drives.

The new line includes the EtherDrive SRX2800, a 16-drive appliance with support for up to 32TB of capacity in a 3U form factor; the EtherDrive SRX3200, a 48TB, 4U, 24-drive appliance; and the EtherDrive SRX3500, a 12TB,  24-drive appliance with 2.5-inch drives in a 2U form factor.

Coraid's EtherDrive products use the AoE protocol to connect disks to servers using Ethernet. AoE is a block storage protocol that uses Ethernet to transport ATA disk commands, without the overhead associated with the TCP/IP protocol. The result, according to the company, is a massively scalable, high performance Ethernet SAN running on low-cost commodity hardware.

Kevin Brown, Coraid's CEO, claims that the EtherDrive architecture yields a price/ performance advantage of as much as 8x over Fibre Channel and iSCSI SANs.

The new EtherDrive SRX-Series storage appliances start at less than $500 per terabyte and support up to six Gigabit Ethernet or four 10GbE connections. The company claims performance of more than 500MBps.

Coraid is also prepping its EtherDrive HBAs for availability in Q2. The HBAs will be available in 2 x 1Gb Ethernet and 2 x 10GbE configurations. Multiple HBAs can be deployed in "port-flooding" mode to provide additional throughput and availability without the need for multi-pathing software, according to Brown.

The HBAs support Linux, Solaris and Windows, as well as Microsoft Hyper-V, Xen Server and ZFS.
