i recently picked on ebay an old HP DL380 G7, i think it was a great deal, lots of disk space and a very low price, for what I need, it was a great deal.
These are the specs:
CPU: 2 x INTEL XEON E5530 2.40GHz 8MB QUAD CORE CPU
HDD: 2 x GENERIC 600GB 15k 3.5" SAS - 4x HP 2TB 6G 7.2K 3.5" SAS
RAID CONTROLLER: P410i/256MB
PSU: 2 x 460W HOT PLUG PSU
It does not have to do very heavy work, it is used mostly as a storage and backup device, the cpu idle at about 3-4% but the power consumption is very high. The ILO report 150W, even a power meter report 150W (wow, i didn't expect that to be so accurate). My PC that is much powerfull idle at about 60W.
So what is it using so much power? What i should change for better power consumption (CPU, PSU ecc).
Maybe it's normal that servers use so much power? (i don't think so), are maybe the 6 disk that use so much power?
Here there is the screenshot of the power meter page: Power Meter Screen
