Data center cooling method with critical device prioritization

摘要

A method and/or computer program product automatically adjusts room temperature in a data center room. A processor in a heating, ventilation and air conditioning (HVAC) system receives a throttle threshold temperature for each of multiple computing devices that are within a data center room, which is climate-controlled by the HVAC system. The processor in the HVAC system monitors a real-time temperature of at least one of the multiple computing devices. In response to the real-time temperature of said at least one of the multiple computing devices exceeding the throttle threshold temperature, an ambient air temperature in the data center room is decreased by adjusting a hardware thermostat in the HVAC system.

1. A method of automatically adjusting room temperature in a data center room, the method comprising:
receiving, by a processor in a heating, ventilation and air conditioning (HVAC) system, a throttle threshold temperature for each of multiple computing devices, wherein the multiple computing devices are physically located within a data center room that is climate-controlled by the HVAC system, wherein the throttle threshold temperature is a temperature that, if exceeded, causes operations of one or more components of a computing device to be reduced, and wherein the throttle threshold temperature is provided by a hardware management module (MM) associated with at least one of the multiple computing devices; monitoring, by the processor in the HVAC system, a real-time temperature of at least one of the multiple computing devices, wherein the real-time temperature is provided by the hardware MM associated with said at least one of the multiple computing devices; in response to the real-time temperature of said at least one of the multiple computing devices exceeding the throttle threshold temperature for said at least one of the multiple computing devices, decreasing an ambient air temperature in the data center room by adjusting a hardware thermostat in the HVAC system; identifying, by the processor in the HVAC system, a critical computing device from the multiple computing devices, wherein the critical computing device has been predetermined to be critical to a mission; identifying, by the processor in the HVAC system, a non-critical computing device from the multiple computing devices, wherein the non-critical computing device has been predetermined to be non-critical to the mission; and prioritizing, for the mission, cooling of the critical computing device over the non-critical computing device, the prioritizing including controlling the ambient air temperature in the data center room based on the throttle threshold temperature for the critical computing device, or a throttling history of the critical computing device.
