I think you have fallen for the hype that everything should be run as a virtual machine ....... (always makes me laugh when vmware tell me I can get better performance as a vm than as a physical :-))
Hyperscale customers HATE hypervisors and "advanced" management, adds cost and complexity for no gain (we are talking 10,000+ physical boxes performing the same function).
You will find that most of these servers will be run with a stripped out linux core running apache or some other open source product acting as a huge scale out farm (usually web facing). In that case 4 DIMM's is more than adequate, throw in a bit of I/O (couple of 1Gb ports will do nicely thanks) and maybe a cheap 3.5" disk to run the OS on ....... and strip out everything else (no DRAC's, iLO's etc) to keep cost low.
For management you only want 2 things, ability to deploy an OS (simple PXE will do) and the ability to reboot the server. Troubleshooting these things goes as follows ........ if its broken turn it off, then turn it back on ....... if its still broken throw it in the bin put a new one in!
Oh and you are right that CPU's are too powerful. Most of these customers are investigating ARM or Atom based platforms (even 1 CPU and 4 DIMMs is too big!) as they are even smaller and more efficient (see the HP Moonshot announcement for what they are doing in this space and it should give you a good feel for what these people actually want and need)
