Abstract: A method and apparatus for system control of a central processing unit (CPU) maximum power detector are provided. in accordance with at least one embodiment, a decision is made as to whether a response of a maximum power detector of the CPU is to be altered. When the response is to be altered, a modified input level is provided to the maximum power detector to alter the response. As an example, the modified input level can prevent the maximum power detector from triggering a power throttling function. When the response is not to be altered, an existing input level for the maximum power detector is maintained. In accordance with at least one embodiment, an apparatus or information handling system can comprise a voltage regulator (VR), a current sensor, a CPU comprising a maximum power detector, and a digital to analog converter (DAC).

Abstract: An information handling system determines a system configuration including a hardware module, and determines an adjusted power budget for the hardware module. The adjusted power budget is based on a calculation including a difference between a date code read from the hardware module and a baseline date, a baseline power budget, a power reduction period and a power reduction interval. The calculation may optionally include a risk factor. In alternate embodiments, an adjusted power budget for a hardware module may be calculated by an order processing system for information handling systems, or by a planning tool for a data center which contains information handling systems.

Abstract: A computer-implemented method dynamically limits peak power consumption in processing nodes of an IHS. A power management micro-controller receives processing node-level power-usage and workload data from several node controllers, including current power consumption and a current workload, for each processing node within the IHS. A total available system power of the IHS is identified including a peak power output capacity and a sustained output power capacity. At least one node peak power threshold is determined based on the power-usage and workload data for each of the processing nodes. The node controllers are triggered to determine and set a central processing unit (CPU) peak power limit for each of several CPUs within each of the processing nodes based on the node peak power threshold, wherein each of the CPUs dynamically adjusts an operating frequency based on the CPU peak power limit.
