SECONDARY MANAGEMENT DEVICE DETERMINING DESIRED FAN SPEED UPON FAILURE OF PRIMARY MANAGEMENT DEVICE

A power device powers a hardware component and a fan cools the component. A primary management device monitors a first characteristic, which is the temperature of the component or the power provided by the power device, and determines a desired fan speed of the fan based on the first characteristic....

Zusammenfassung:	A power device powers a hardware component and a fan cools the component. A primary management device monitors a first characteristic, which is the temperature of the component or the power provided by the power device, and determines a desired fan speed of the fan based on the first characteristic. A secondary management device monitors a second characteristic, which is the temperature of the component or the power provided by the power device, and sets the fan speed to the desired fan speed determined by the primary management device. The secondary management device constructs a profile of the fan speed in relation to the second characteristic by periodically recording the fan speed and the second characteristic. In response to the primary management device failing, the secondary management device determines the desired fan speed based on the profile and set the fan speed to the desired fan speed that it determined.
