Re: DL385 + RHEL, performance issue

Well, if I did not check the performance (bad practice) I would be very angry about HP. And just buy IBM next time.

Re: DL385 + RHEL, performance issue

You really should not have to mess with the BIOS CPU settings as having it set at maximal power will:

1) make your server less GREEN (if you care)
2) will always have your fans at full speed
3) power onsumption
4) shorten the life of your machine

a properly configured Proliant G6/G7 should have the HP bits ON to interact with the backend BIOS/iLO "properly" and do such things as on-demand CPU throttling, etc.

RHEL 6.0 from what I have heard has the functionality "built-in".

Re: DL385 + RHEL, performance issue

Solution :

Users of RHEL 5 + DL350 (All HP server ?) should be advise to get rid of the power capping (In the BIOS). Otherwise, the machine will perform at about 50% of the CPU capacity.

Thanks to Alzhy for pointing this.
