Dear John, et al.,
I could bond all the nodes in my cluster (Dell 1750s and Dell1850s with dual Gig ethernets on the motherboard). However, I cannot tell if I would get more bandwidth that way or just more ethernet packet resends because of out of order packets.
Do you get improved performance on your "bonded" cluster?
Does bonding two ethernet cards add to the performance of an NFS beowulf cluster, with the master node being the NFS server? Or is bonding just a method to improve availability to the node if one ethernet card fails?
I cannot find any metrics on bonding or teaming ethernet cards.

We recently put in a cluster with bonded gigabit, however that was done
using a separate dual-port PCI card.
On Supermicro, the IPMI card by default uses the same MAC address as the
eth0 port which it shares. You could reconfigure this I think.
(lan set 1 maccaddr <x:x:x:x:x:x>
Also Supermicro have a riser card00:30:48:2d:49:44
which provides a separate network and serial port for the IPMI card.
Tyan probably have similar.
