I am looking to run a M1000e out of my residence for a home based business.  It has three Force10 panels, six E2700P-00 power supplies, and sixteen identical half height m620 blades with dual E5-2630L and 64gb of DDR3L.  I have two 120v -240v Chatsworth enterprise PDUs.

I am trying to figure out the recommended power requirements for this exact setup so I know what upgrades will need to be made to my residential power circuity to accommodate it at full load.

Is it recommended to run on a 240v circuit - should I switch to 240v power supplies rather than 120v and install 240v circuitry in my residence? 

Also, if I upgrade my blades to m630 or m640 in the future will the full load power requirement remain the same, or should I consider future-proofing my circuitry now?

Thanks.
