ATA over Ethernet, take a look here for explanation:

700 MHz PIII should be fast enough for a disk server. You can put all
your extra drives in it, run RAID/LVM on it and export it with AoE.
At this point you mount it on your other machine as if it was a local
drive. For something fancy you can use a cluster file system and have
the same drives mounted on other machines. The possibilities are endles
on what you can do.

One more example is to have multiple computers with exported AoE drives
and run LVM on top of them and present them to the Myth backend.
