ESXi

Hello.

We got server with two Intel X5550 processors.

How can i verify what Intel Turbo Boost is working?

It works, its built into the hardware, you can't control it, you can't "see" if it's working.

So what is your interpretation of what Turbo Boost is supposed to do? It's not like a "turbo" button despite it's name.

I think it is a complex feature. It may not work due to BIOS misconfiguration or error.

I found some tools for Windows, but not ESX.

Have a look at this thread:

Do you have "blower whine" coming from the processor? It's how you (typically) know when a turbo is "working"...

Sorry, just couldn't resist... :smileygrin:

Consider awarding points for "helpful" and/or "correct" answers.

would you not be able to see it working by it reducing the CPU % ready times in esxtop?

I would of thought when it kicks in it will drop the wait times significantly.

If turbo boost were working, you would first see "un-used" processors "park" and then you would see the remaining processors core frequency increase. I do not know of a way to monitor the processor core freq from within ESX but a hardware SNMP agent might be able get that info from under ESX.

As an indirect measurement, I use ESX in Workstation 7 to sandbox some scenarios for work. For a fact, the processors never slow down but some do park in ESX on Workstation 7.

If you have your manufacturer's hardware SNMP agents running or have ILO (or simular functionality from your BMC) you might be able to see what Turbo Boost doing when ESX is loaded directly on the hardware.

I have not pursued this on my own because I do not run ESX in a manner where I would ever expect that boost to a core or two would be desireable in that that would require some physical cores to shut down. For me more cores == more better.
