Hi zaroth - We do not use Kill-o-Watt meters since we use calibrated Extech TrueRMS units for our "desktop" testing. We also have a few racks in Sunnyvale, California that we use APC metered by outlet PDUs for and that we actually calibrated by testing with the Extech units and found two of over a dozen that gave us consistent readings across PDUs and ports. This unit is in a SC515 chassis with redundant PSUs. Even with 4x 7200 rpm Seagate 2.5" drives, a 64GB mSATA drive and a Samsung SM951 m.2 SSD it is still pulling 0.24A on 208V (so 0.48A on 208V). If you were to gain a bit of efficiency running a single PSU, you could easily fit these in 1A on 120V power envelope. What we have seen several folks do with similar D-1540 machines is actually use 1U 1A/ 120V hosting (which is very inexpensive) to deliver cheap local PoPs for their applications. We have been strongly considering decommissioning our Las Vegas 1/2 cab DR site and moving to this sort of distributed model as there are a lot of benefits with this. We published more complete benchmark results ( http://www.servethehome.com/intel-xeon-d-1587-benchmarks-16-core-xeon-d-is-here/ http://www.servethehome.com/intel-xeon-d-1587-benchmarks-16-... )of the D-1587 yesterday, expect more in terms of reviewing the overall platform next week. The Xeon D is very platform dependent for power and the particular unit we have does have the additional LSI/ Avago/ Broadcom SAS 2116 (16 port SAS2) HBA onboard.
