Hi,   It seems that you will need the 2nd CPU. [URL]
I am looking to run a set of 3 Dell R630's, each with a CPU in Slot 1, all Side A RAM filled. I need to have 4 10 Gig NIC's per machine, so I would like to add 2 expansion cards to each. Is there a configuration that will let CPU 1 run 2 expansion cards without needing to have CPU and RAM in Slots 2 / Side B?
