What location did you desire to Colocate this C6100 machine?
You should be able to get away with just 3U of space, one network uplink, and 2-3 power ports (depending if using redundant power on the C6100 or not).
FYI...the C6100 is a pain for configuring the remote kvm functions. Our staff complains about them all the time. Once you get used to it, not so bad, but really not as simple as alot of other ones out there.
Wouldn't you need someone physically at the datacenter to setup the KVM / IPMI functions for you? Those do have to be set in the BIOS which would require either someone physically there or an already-functioning KVM device such as a Spider.
In order to avoid the data center charging you extra you need to pre-configure the network before shipping it to DC.
This requires at least basic knowledge plus obtaining IP details from DC before shipping.
