I have been following a storage technology called "AoE" and wondered if in ever ending quest for affordable space, had anybody given it a try on this forum.

AoE enables an export of a storage device (hard drive, raid) over standard Ethernet network to other computers on the network that can use the device as if it was a local device. In short, one should be able to format and use a hard drive locally that physically sits on another box. Apparently there is no limit to how many devices can be exported this way.

There is a commercial company that builds storage devices using this technology http://www.coraid.com/ but being an Open source company this technology is available under GPL. It all started with Linux, but currently there are drivers available for Win, Mac, FreeBSD and few other os.

There is a wiki in wikipedia that contains some links, including this one http://www.lbserver.org/aoe/ that actually provides a liveCD for testing and a way to create a simple permanent server that exports its drives as devices.

Also, Coraid has created a special Linux distro to set up a fileserver that consolidates device from across the network and exports them as file systems to clients (NFS and Samba).

This technology matures and is very tempting to try, as it eliminates the limits of fileserver growth and for non-commercial use can breath new live into discarded hardware.

Has anybody tried this technology ? Any experiences to share ?

A friend of mine has done a bunch of ATAoE testing, he says it works fairly well, but of course is not a published standard. (it's only standard because only one company makes the code right now)

Another cool thing I found the other day:

AoE driver is standard in later releases of 2.6 of kernel, it kind of makes it a standard, but I agree that there are not many implementaions of it (the one I know of is Coraid). I'm glad that your friend had good experiences, I'm planning to set one box as soon as I get Gigabye router.
