FWIW we run two NFS servers (dual 2.0GHz Opteron 240's) with users split 
across the two and they cope with 3 clusters, two with ~180 CPUs and one with 
~30 CPUs, all run at an average of 83% utilisation over the last 12 months 
(one at around 92% utilisation for the last 3 months).

So yes, NFS should be fine.  Just don't try and run Gaussian on it. :-)

cheers,
Chris
