|> What exactly are you trying to gain, avoid, or do?

Gain: seperate database storage from processing. This lets me move
clusters from one server to another easily. Just stop the postgres
instance on server A and unmount it's filesystem. Then mount it on
server B and start postgres instance on server B. It gives me some
fail-over capability as well as scalability and a lot of flexibility in
balancing load over multiple servers.

Avoid: paying for brutally expensive FC gear.
