  • 1.  vSphere w/ Dell Controlled Turbo?

    Posted Aug 10, 2018 01:02 PM

    I'm just getting back into Dell HW after a 10-year stint on HP. I'm looking at some specific settings within the Dell BIOS and came across the "Controlled Turbo" Proc option. At first I thought it was their hyper-threading tech, but now I'm reading it more as Proc over-clocking. Can someone verify that? Is there any information on performance gains vs. MTTF? or increased failure rates? I can only guess that as there is more wear and tear on the HW that would shorten product life (proc, fans, etc...)?

    Can anyone recommend or otherwise?


    Edit: Is there any effect on vSAN performance?

    I notice what looks like CPU cycling spikes to ~8-10% when idle (no load, no powered on VMs), while other hosts my cycle the same, but the intervals are spaced further apart.

    I followed one of the Performance Series session on last VMworld and one of the talks was about the powersaving options can C,P states stuff. The presentation contains the vmware prefered settings for HP and Dell servers for the general purpose use, which means that VMware would like to see to get the controll more to the ESXi hypervisor instead the "Maximum performance" setting which disable powersaving options which negative effect the CPU turbo clocks.

    I remember that you watch the vmworld session on youtube. I'll see if i can find it.
