Abstract

Servers, methods, and computer-readable media for performing thermal management of a server including a plurality of data storage devices. In one example, a server includes a controller configured to apply a machine learning model to identify a first portion of the plurality of data storage devices located in a hot zone relative to a second portion of the plurality of data storage devices located outside of the hot zone. The controller identifies the hot zone based on thermal data received from each of the plurality of data storage devices. Based on an identification of the first portion of the plurality of data storage devices located in the hot zone, the controller performs thermal management of the plurality of data storage devices by logically shuffling the plurality of data storage devices to create a distributed hot zone.
