At least the way I like to build infrastructure, physical servers don't really matter. If for whatever reason servers had to get moved, their mac address would be updated to reflect it's location. I wrote some code a while back which grabs all the mac addresses from a switch and use that to map their physical location. It's quite simple, it looks at a port to see if it has multiple mac addresses behind it, if it does, it ignores it, if not, it maps that port out and labels it appropriately. There's also a little bit of logic to figure out what kind of a device a port is (whether it's another switch, a server, a pdu, etc), which also helps with my own personal continuing de-emphasis on the physicality of computing.
