We have a very similar setup, and I can only second Kay's experience.
Best regards,
Dirk.

I have a very different experience with NFS: we are using Gigabit Ethernet, and
a 64bit RHEL6 clone with ECC memory as a file server; it has RAID1 ext4 home
directories and RAID6 ext4 for synchrotron data. We have had zero performance
or reliability problems with this in a computer lab with ~ 10 workstations, and
I have seen 115 MB/sec file transfers via NFS, at peak times.
Just make sure to export using the "async" option.
HTH,
Kay

Be careful that running data intensive jobs over NFS
is super slow (at least an order of magnitude compared
to writing things on a local disk).
Not only the computation is slow, but you may be slowing down
all other users of the cluster too...
