We recently got 33 new cluster nodes all of which have two onboard GigE
nics. We also got two powerconnect 2748 48 port switches which support
IEEE 802.3ad (link aggregation). I have configured the nodes to do
Ethernet bonding to aggregate the two nics in to one bonded device:

Now I am wondering what is the best way to configure my switches. I
guess I could do it in two ways: use the IEEE 802.3ab on the switch,
plug both nics of a node into one switch, and have some nodes on either
switch, or perhaps for each node, plug one nic in one switch and the
second nic in the other switch.

So what in your experience is the best way to set up these
interconnects?
