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 device peak power limit for each of several variable performance devices within each of the processing nodes based on the node peak power threshold, wherein each of the variable performance devices dynamically adjusts a value of a corresponding device performance metric based on the device peak power limit.
