VMS is one of the few that can have a disk farm and a cpu farm as a result
of the clustering technology. It's nice in that my MV2000 with it's tiny
159mb disk can be a cluster member to the 3100 allowing common files and
all sorts of nice things including common configuration and diskless

I run three Nt servers (3.51 SP4) and they are extremely reliable but not
heavily loaded. My understanding the NT doesn't load well. Whats funny
is a could stuff a 3100m76 in there and replace the whole lot and still
have cpu left over. VMS does (over)load gracefully.
