I have been reading the ongoing discussion on network usage with some interest, mainly because in all (admittedly very small, 4 to 8 node) clusters we have set up so far, we have always gone with doubling the network. Nowadays we mostly run a 100 MBit/s "el cheapo" FastEthernet for control, NFS and monitoring, while the faster Gigabit is exclusively for MPI. Applications are CFD, with various levels of granularity.
We are running a 1Gb network that has 10Gb connections to the head node and fileservers as well. We also have a 100Mb network that is seperate for management and BMC traffic. Since our systems have two ethernet ports on the motherboard, the only cost was the switches and cables. For the price, I think it is very worthwhile.
