I'd strongly recommend Lustre.  It will work perfectly well from a
single server node and give much higher bandwidths than NFS.  If you
have two nic's you can also serve up the file system over both and see
around 150MB/s total bandwidth.

Also, if you need more storage in the future, you can just add more
servers... and get linear scaling of bandwidth.
