RAID controller question...

[Joel Jaeggli]

In many clusters (the bulk data server being a noteable exception) a
single, or a few machines provide large blocks of nfs exported space to
all of the nodes, so that binares or data files can be shared in common
between all the machines. This keeps the per-node cost down since the
machines don't need to have much, or in some cases any local disk. This
can also make administration of the cluster more sane if you only have to
change things in one place.
