This is a very common configuration for our clusters.
Most motherboards these days come with dual on-board gigabit.
One is used for general cluster traffic and NFS.
the other is dedicated to MPI traffic, using a separate switch or
stack of switches.
(The normal MPI implementation is the low-latency SCore)
On machines with separate service processors (for example Sun Galaxy)
we put in Netgear 10/100 switches and cabling for a management network.
With Serial Over LAN we don't have any need for serial console cabling
