DL380 G7 – 2 x L5640 (6-core @ 2.26GHz, 60W), 24gb (6 x 4gb DDR3), 6 x 2.5” SAS, 1 x HBA
- 24hr Avg usage 236W (Power regulator mode : Dynamic power)
DL380 Gen8 – 2 x E5-5670 (8-core @ 2.60GHz, 115W), 256gb (16 x 16gb DDR3) 2 x 2.5” SAS, 2 x HBA, 1 x 4-port 1G NIC
- 24hr Avg usage 178W (Power regulator mode : MAX (Static high))
This is a reasonably idle workload (G7 is stand alone running windows, Gen8 is running ESX) and last 24hrs is Sunday including evening until midday or so Monday.
Look at the extra memory in the 2011 system, that also adds some watts. Also windows is generally a better power saver than an ESX server.
Note that is the HP hardware , I really can't comment on white box stuff.
I do have blades all with 512gb ram on E5 v1,v3,v4 (no v2) config and all with same dual port 10g + 2 x dual port HBA i will check on when I get some time out of interest since that power usage will exclude fans and only the 2 x 300gb disks included so is about the closest you can get to same/same config.
Evan thanks for this I really appreciate it and it is certainly some interesting results! Is that at 230 V as we use 230V here but not sure that makes a difference with power wattage consumption given that all voltages are stepped down anyway. 115 Watts is not terrible at all and looks like a sweet spot, Its ML310e Gen 8 servers I am running at the moment but that is a figure I can live with and if I ran in single proc mode first then that would save even more. Interesting,..,.
