core node (the one I mentioned above). I could do that with nfs but

so I
cannot use some other networks here. Is there a good way of doing
that? Some
words like i-scsi and cluster-FS come to mind but to be honest, up
to now I
never really worked with them.
Any ideas?

I am under the impression that NFS can saturate a gigabit link.
If for some reason that it cannot, you might want to try PVFS2 (http://www.pvfs.org
) over Open-MX (http://www.open-mx.org).
