Systems and methods for thermal control of a storage enclosure

A method comprising:

• measuring a physical quantity in order to detect an overcurrent condition of a power supply module, wherein the power supply module is configured to shut down in response to detection of the overcurrent condition;
• based on the physical quantity, determining a power delivered from the power supply module;
• based on the power delivered from the power supply module, determining a desired rate of a flow of air from at least one air mover configured to cool one or more storage resources received by a storage enclosure by delivering the flow of air within the storage enclosure and causing the at least one air mover to deliver the flow of air in accordance with the desired rate;
• calculating an estimated power delivered to the one or more storage resources based on the power delivered from the power supply module;
• periodically receiving from the one or more storage resources a signal indicative of a thermal status of the one or more storage resources;
• responsive to receiving the signal, storing to a data structure data correlating the thermal statuses to the estimated power delivered to the one or more storage resources at the time the signal indicative of a thermal status is received;
• and
• determining the desired rate of the flow of air based on the data stored to the data structure in addition to the physical quantity.

A controller for thermal control of an enclosure comprising one or more storage resources, the controller configured to:

• measure a physical quantity in order to detect an overcurrent condition of a power supply module, wherein the power supply module is configured to shut down in response to detection of the overcurrent condition;
• based on the physical quantity, determine a power delivered from the power supply module;
• based on the power delivered from the power supply module, determine a desired rate of a flow of air from at least one air mover configured to cool one or more storage resources received by the enclosure by delivering the flow of air within the enclosure and causing the at least one air mover to deliver the flow of air in accordance with the desired rate;
• calculate an estimated power delivered to the one or more storage resources based on the power delivered from the power supply module;
• periodically receive from the one or more storage resources a signal indicative of a thermal status of the one or more storage resources;
• responsive to receiving the signal, store to a data structure data correlating the thermal statuses to the estimated power delivered to the one or more storage resources at the time the signal indicative of a thermal status is received;
• and
• determine the desired rate of the flow of air based on the data stored to the data structure in addition to the physical quantity.
