I would like to implement some CPU frequency scaling on a prospective server that I intend to build.
My question is this: For the power management features in ESXi5 - is it necessary for BIOS support for frequency scaling? I know the CPU obviously must support it but ESS boards have a separate feature for selecting a power saving profile within the BIOS - is it necessary to have this support in the BIOS too?
I only intend to use the power management features within ESXi.
Thanks.
