And what are the clients of this fileystem?  So far you have only
specified the servers.  What machines will actually use this filesystem?

Well, technically it's possible as long as you can run a Lustre patched
kernel on those workstations (which might contradict the requirements of
the workstation users).

What about the performance impact of Lustre on those students'
workstations?  Are they going to be happy sharing the resources of their
workstations with Lustre object storage services?

Generally we advise against doing anything on a Lustre server except run
Lustre.
