Pictures or it didn't happen.
Give this a try. It very good at tracking physical assets such as rack/server. It doesn't doe a whole datacenter but we modified the code to give just back rows of racks.
Now the physical asset track is in one place, for inter-dependency, I create an diagram of the interconnect at a more logical level since I know the physical will be correct. This could be say a set of switches connecting to a distribution switch and etc..
