Bird's eye view: you have a block device, for example /dev/nda. It acts like any other block device, which means that you can create a file system on it, make it part of a mirror or RAID 5 array and so on. But the actual hardware is somewhere out on the network.
Most likely a *local* network, of course. Maybe someday you could do this on a public network, but local is scary enough. The bug list for this project makes you wonder why anyone would even think about deploying it for important data - it just goes on and on and on with hangs and crashes. Sounds like a great way to spend the weekend, doesn't it?
