FWIW - we've got a bunch of the DL360 G4's and found a very nasty problem 
with the way the onboard Broadcom reacted to our HP switches - by default 
we forced the NIC's to 100Mbit/FDX. This resulted in a system that could 
send 'small' packets fine (e.g. dns) - but bogged down on anything large 
[it'd work, but not fun getting about 6k/sec for some transfers).

After fiddling with the switch ports, putting the NIC's back to 
'auto-select' fixed it - which is ironic, as we have a bunch of Intel 
Pro1000's that need exactly the opposite to work properly [i.e. we _have_ 
to lock them at 100/FDX to work with the switches].

I love 'standards' :)
