Of course, if you let the servers handle the AFR, then there's no need
for Unify, as the AFR'd volumes can be exported directly to the
clients.  If combined with RRDNS, this creates a fault-tolerant
mirrored cluster, as the clients will just keep trying until they get
a working server, and the servers will replicate among themselves
until the missing node(s) return(s).
