I fully realise there are arguments both ways.
We normally have a local disk on cluster nodes. It is formatted at
install time, and either synced or formatted at reboot time.
We can choose a partition table on a per-node basis.
The clusters we put in for the NGS in the UK have two disks per node,
one for data as you describe. We don't software RAID them though!
I heard at CERN that if you are buying ATX cased systems it was more
expensive to have them without disks in large quantities.
(Let's not ignite the rack/ATX debate please)
