Today, Fibre Channel is the dominant enterprise storage technology, but as with all technologies, eventually something better comes along. If you're lucky, that something is also less complex and less expensive. For storage, that something may be ATA over Ethernet (AoE), a simple and open network protocol that allows storage to be accessed over Ethernet.

AoE sends ATA commands over Ethernet frames without the overhead of IP. Communication is done via MAC addresses and is non-routable. Best of all, AoE devices appear as regular block storage. That means you can do with them whatever you would do with local storage. You can manage AoE storage with LVM, create RAID arrays out of your AoE devices, or put a cluster file system on top of them.
