AoE SAN Storage

Revolutionary Storage Area Networking (SAN)

Coraid’s EtherDrive® SR1521 Storage Appliance is a fast and simple alternative to iSCSI and Fibre Channel RAID boxes. EtherDrive® storage uses the open ATA-over-Ethernet (AoE) storage protocol. AoE is a simple way to move storage out of your servers and onto an Ethernet storage network. With AoE, disk read/write requests are placed directly into Ethernet frames. The AoE protocol doesn’t need TCP/IP so its easy to process and doesn’t require special network interface cards.

EtherDrive® storage is accessible and shared by any server/host machine attached to the storage network. Disks inside the storage appliance are assembled into RAID volumes and presented as AoE block storage devices. Servers discover and mount AoE storage devices by using an AoE software driver. The AoE driver presents an AoE device, to the host OS, as a local disk drive. AoE storage is fast and can be used like any other disk drive.

Unlimited Storage

Users save money by installing their own disk drives. The SR1521 storage appliance accepts any standard SATA or SATA2 disk. As disk capacity increases, higher density disks can be installed quickly and easily.

There are no limits to how many disks can be attached to a server. There are no constraints to how big an AoE storage network can be expanded. Each time a new EtherDrive® Storage Appliance is added to the storage network, more processing power is added and therefore aggregate throughput and IOPS performance of the storage system is also increased.
