the way we use ken's file server is to connect it to
aoe storage which internally provides raid. in fact,
we use the properties of the mirrors in the file server
to provide off site backup. since the mirror always reads
from the first element which is very close, and since writes
are always done in the background and have no user
impact, the mirror doesn't change user-visable performance
at all.
