I have a user who is requesting that we change our VMWare Host Power Management Policy from Balanced to High Performance. 


Questions 1: Do Nutanix hosts support VMWare Power Management features?

Question 2: We are migrating to all AHV early next year. Does Nutanix have a corresponding setting for VMWare Host Power Management Policies?

Hello @Bryce_Smith 

Just to add a feature of AHV here regarding the second question.

 

Question 2: We are migrating to all AHV early next year. Does Nutanix have a corresponding setting for VMWare Host Power Management Policies?

 

To quote from the Power Policy Settings document 

https://portal.nutanix.com/#/page/solutions/details?targetId=BP-2015-Microsoft-SQL-Server:top_power_policy_settings.html

Nutanix AHV enables the high-performance mode automatically.

So when you will migrate to AHV environment, you don’t need to configure any setting for the power policy to be High Performance. 


Hope this helps!

Questions 1: Do Nutanix hosts support VMWare Power Management features?

Provided that the options is supported by BIOS version in which case High Performance Policy option is not greyed out in the vSphere client, it is supported.

That being said I feel obligated to remind about necessity of research on the feature itself and its best practices. I am certain you have done so already so it’s merely a per-caution on my part.

Question 2: We are migrating to all AHV early next year. Does Nutanix have a corresponding setting for VMWare Host Power Management Policies?

There is a way to disable cpuidle state to benefit performance of highly sensitive applications. I would suggest however to raise a case with Nutanix support to perform this task.
