Can I using Power Capping with VxRail?

Hi norick-san,

For reference, the vSAN Design guide says follows.

Processor Power Management Considerations

While not specific to Virtual SAN, processor power management settings can have an impact on overall performance. Certain applications that are very sensitive to processing speed latencies may show less than expected performance when processor power management features are enabled.

A best practice is to select a balanced mode and avoid extreme power-saving modes.

There are further details found in VMware KB article 1018206(http://kb.vmware.com/kb/1018206).

VxRail default power management policy is "balanced".

I think I should not change.

If you have to set a limit, I think it is simpler to use a resource pool setting.
