Method and apparatus for determining whether a cooling device in a computer system is responsive to control signals

摘要

Some embodiments of the present invention provide a system that determines whether a cooling device in a computer system is responsive to control signals. During operation of the computer system, a control signal is sent to the cooling device. Next, a response of the computer system to the control signal is measured, wherein the response includes a temperature profile. The frequency content of the control signal is then compared to the frequency content of the temperature profile to determine whether the cooling device is responsive to the control signal.

1. A method for determining whether a cooling device in a computer system is responsive to control signals, comprising:
sending a control signal to the cooling device to modulate an operation of the cooling device, wherein the control signal has a frequency content, and wherein modulating the operation of the cooling device comprises, when the cooling device is responsive to the control signal, using the cooling device to cause a temperature variation for the computer system based on the control signal; measuring a temperature profile of the computer system while modulating the operation of the cooling device; comparing the frequency content of the control signal to a frequency content of the temperature profile; determining that the cooling device is responsive to the control signal when the frequency content of the temperature profile includes one or more components of the frequency content to the control signal; and determining that the cooling device is not responsive to the control signal when the frequency content of the temperature profile does not include one or more components of the frequency content to the control signal.
