[geeks] Ran the numbers - V240

[Josh Snyder]

Have you looked at any of the newer Xeon-D solutions? I have been 
playing around with a Supermicro Xeon-D "server" at work, 8 cores @ 
2.2Ghz all for about 35 watts of power. The board also includes 2 
10GBASE-T 10Gbit interfaces that if you disables them in the UFI it 
drops the power usage down to about 27 watts. Granted this is new 
hardware and not exactly cheap but performance per watt is rather 
impressive.
