CPU Power Voltage Regulation Modules (EVRD 11.1)

Voltage regulation to the 5500 series 2S processor (Nehalem EP) is provided by EVRD (Enterprise
Voltage Regulator-Down). EVRDs are embedded on the planar. CPU core voltage is not shared between
processors. EVRDs support static phase shedding and power management via the PMBus.
