A method includes a plurality of voltage regulators distributing power to a plurality of components within a compute node, wherein each of the voltage regulators has a controller, volatile memory and non-volatile memory. The controller of each voltage regulator temporarily caches operating data for the voltage regulator in the volatile memory of the voltage regulator, wherein the controller temporarily caches the operating data collected from the voltage regulator over a sliding time period. When a first voltage regulator from among the plurality of voltage regulators experiences a fault event, the controller of each voltage regulator detects the fault event and automatically copies the cached operating data for the voltage regulator from the volatile memory of the voltage regulator to the non-volatile memory of the voltage regulator in response to detecting the fault event. |
