In my last training Fabian Lenz and I discuss pro and con of power management in ESXi.
We thought DPM is mostly used in VDI-environments. In those environments the savings would be the best, because the virtual desktops didn’t work at night and many of the ESXi hosts could be powered off. But DPM ist not the only thing which affects the power consumption. ESXi could use ACPI C- and P-States from the CPU to control the power of the physical cores. Fabian experiements with a bigger VDI environment and gets interessting informations with activated DPM (watch his blog).
