Dell R210 power consumption

Just recording the power ratings I measured with this plug-in meter and a Dell R210 server. Firstly some base readings with no operating system installed and the machine powered up (with no power applied the Drac Express draws about 26W).

No OS, with 2 Seagate 2.5” drives, 2x4GB RAM, DVD, Drac Express: 60.75W
No OS, with 1 Seagate 2.5” drive, 2x4GB RAM, DVD, Drac Express: 58.32W
No OS, with 2 Seagate 2.5” drives, 2x4GB RAM, Drac Express: 60.75W
No OS, with 2 Seagate 2.5” drives, 2x2GB RAM, Drac Express: 61.25W
No OS, with 2 Seagate 2.5” drives, 1x4GB RAM, Drac Express: 60.75W
No OS, with 1 Western Digital RE2, 2x4GB RAM, DVD, Drac Express: 57.6W
No OS, 2x4GB RAM, DVD, Drac Express: 55.0W

Now putting an OS on the machine and actually optimising so the OS can power down the CPU, etc.

FreeBSD 8 (base), with 2 Seagate 2.5” drives (RAID1), 2x4GB RAM, DVD, Drac Express: 60.75W
FreeBSD 8 (optimised), with 2 Seagate 2.5” drives (RAID1), 2x4GB RAM, DVD, Drac Express: 55.0W
FreeBSD 8 (heavily optimised), with 2 Seagate 2.5” drives, 2x4GB RAM, DVD, Drac Express: 51.0W

On a more expensive properly calibrated meter we tickled 47VA with that last configuration.
