where Lustre and GPFS (IBM proprietary) are probably the only two
that are used in large scale HPC 'cos they're the only ones that scale
to 1000's of clients and beyond.

meaning block based shared SAN style storage only?

and now you're just deliberately trying to be confusing... ;-)

there's also appliance-like gizmos such as
- BlueARC
- NetApp
- EMC
but I don't know enough about them to say which categories they fit
into. they're generally too expensive for us cheapskates in HPC anyway.
