Patent number: 11150709Abstract: An apparatus for monitoring and maintaining thermal exhaust temperatures for monitored servers may include a processor in communication with an exhaust temperature control system. The processor may implement various control loops to monitor inlet and exhaust temperatures for one or more servers, and the processor may monitor temperatures of various hardware components within those one or more servers. When the processor determines that a hardware component for a given server is overheating, the processor may take steps to decrease the temperature of the overheating hardware component for the given server. To determine whether a hardware component is overheating, the processor may leverage the hardware component's operating temperature margin.Type: GrantFiled: August 5, 2019Date of Patent: October 19, 2021Assignee: Google LLCInventors: Gregory Imwalle, David W. Stiver, Andrew J. Schran, Thomas Chris Newcomb

Patent number: 9565790Abstract: A system includes a first computing component and a second computing component. A first measurement indicative of a temperature of a first computing component is received. A second measurement indicative of a temperature of a second computing component is received. A thermal value is calculated for the first computing component based on the first measurement and the second measurement. In response to determining that the calculated thermal value exceeds the threshold, an operational or physical parameter of the system is modified.Type: GrantFiled: February 10, 2014Date of Patent: February 7, 2017Assignee: Google Inc.Inventors: David W. Stiver, Gregory P. Imwalle
