Some people use an extra NIC for command and control.  Others use it for I/O 
throughput. Others use an extra NIC for redundancy.  It just depends upon the 
applications that they are running.  You may want to setup a small cluster 
and see what works best for your application, before setting up a larger 
cluster.
