If you want to know more about power profiles and power regulator: HP has a whitepaper on the topic. ![]() Strangely, the settings are named differently in BIOS and iLO. Switching it to HP Static High Performance Mode fixed the issue. Sure enough, the “bad” VM was on a server with incorrectly configured power profile. It can even be changed from iLO, taking effect immediately: Luckily the power profile setting is not only available from the BIOS, but from the iLO console, too. I suspected the power profile setting of the server hosting the “bad” VM to be wrong, but how to check without rebooting the server and accessing the BIOS? These are production systems and we cannot use vMotion to move the VMs off the server because the VMs are on local storage. I ran some benchmarks, comparing it to a “good” VM:ĭepending on the benchmark, the “good” VM is between 28% and 244% faster than the “bad” VM. When I looked at the problem I soon found a VM with bad CPU performance. But still – some VMs were performing worse than others. Consistent with FAR 12.211 and 12. Currently i have HPDM 4.7 SP10 version installed in my environment it works good and i just saw that there is new released 5.0 with new features, components and GUI it looks completely different and cool. ![]() I have some question upgrading to new released HPDM 5.0. That fixed the problems with really awful CPU performance we had in the beginning. Valid license from HP required for possession, use or copying. Downloading HP Power Manager software - HP Support. When we prepared our servers for use as virtualization hosts for Citrix XenDesktop we took great care to configure the HP Power Profile for Maximum Performance: That sounds good but is bad – at least for CPU performance in a VDI environment. When you buy a new HP server it comes with the BIOS setting HP Power Profile set to Balanced Power and Performance.
