DYNANMIC PEAK POWER LIMITING TO PROCESSING NODES IN AN INFORMATION HANDLING SYSTEM

摘要

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.

1. A computer-implemented method to dynamically limit peak power consumption in processing nodes of an information handling system (IHS), the method comprising:
receiving, at a power management micro-controller, a plurality of processing node-level power-usage and workload data from a plurality of node controllers, including a current power consumption and a current workload, for each processing node within the IHS; identifying a total available system power of the IHS including a peak power output capacity and a sustained output power capacity; determining at least one node peak power threshold based on the power-usage and workload data for each of the processing nodes; and triggering the node controllers to determine and set a central processing unit (CPU) peak power limit for each of a plurality of 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.
