That means you either need a bigger central server or something like
pNFS or Lustre.
http://www.opensolaris.org/os/project/nfsv41/

The later also owned by SUN, now.
The stuff you want is really mainly found in gear provided by vendors
that supply storage for HPC-clusters...

I'm not sure what the status of pNFS is in Linux (given the fact that
NFS on Linux has only relatively recently "matured").
