A compute cluster (ie number crunching), resilience is not the issue.
Currently file sharing is via NFS (although each node has some hard disk),
they have a SAN so use of GFS is possible - not looked at that yet.
The nodes talk to each other by MPI (Message Passing Interface).

They want to be able to refesh (rebuild) the compute nodes with different
installs.
