I'm closing in on purchasing a Dell PowerEdge R710 rack server and am curious to know the difference between Dell's power saving bios setting and their performance bios setting. Should I be concerned about choosing the power saving setting? I'll be using this rack for terminal services and definitely want performance when performance is needed. That being said, for the other 3/4's of the day when employees have gone home I'd prefer it if this server wasn't running at 110%.

Thanks in advance.

I don't know the details but the R710 has a BIOS Power/Performance options page. In it you can select to turn on and off features which will either save power and boost performance.

You can change these settings so I wouldn't worry about it.

That said, I think it's really awesome that dell offers this option rather than just shipping the random collection of arbitrary bios settings most vendors seem to use. –  mattdm Dec 4 '10 at 3:55

Donno about r710, but for servers my approach is to have BIOS in performance mode and eventually let the OS manage power consumption when on low load via ACPI, cpuperf or whatever you like

I hooked up a WattsUp! meter to our R710 and I couldn't tell much of a difference between the two either at idle or at full tilt. So I left it at Maximum Performance. At idle they only draw 185 watts, full tilt I got it up to 295 watts (in our config.)

Great thinking. I bought a WattsUp Pro for my father last Christmas. Thanks for posting your findings. –  JohnyD Oct 16 '09 at 11:08
