The invention discloses a heat dissipation method for intelligently regulating fan rotational speed according to equipment power consumption, which relates to the technical field of cloud server architecture. The method comprises the following steps: a hot swap circuit is arranged on a power supply path of a high power consumption device; The hot-swap chip monitors the power consumption information of the high-power equipment in real time and transmits it to the BMC. The BMC calculates the fan speed required by the current equipment under different power consumption according to the power consumption information of the equipment, and intelligently adjusts the fan speed according to the obtained fan speed data. The invention discloses a heat dissipation method for intelligently regulating fan rotational speed according to equipment power consumption, For some high-power devices which can not get the temperature directly through I2C in the server, the function of intelligently regulatingthe fan speed through power consumption is realized, which reduces the power consumption of the whole system at low load, and under some conditions, the power consumption of the device can be limitedthrough BMC, so as to achieve the effect of load balance and energy saving.
Description
technical field [0001] Embodiments of the present invention relate to the technical field of cloud server architecture, and in particular to a heat dissipation method for intelligently adjusting fan speed according to device power consumption. Background technique [0002] With the vigorous development of artificial intelligence, new product forms are constantly appearing in the server. A single AI server contains multiple GPUs or FPGA cards with high power consumption. With the increase of device power consumption, a single PCIe card or other form of device has already exceeded the 75W specified by the PCIe specification. Most of these devices or cards use external power supply to Support high-power equipment. The increase in device power consumption is bound to increase the heat generation, and the density of high-power consumption cards in the server is also increasing. The heat dissipation bottleneck provided by the whole machine is gradually shifted from the CPU to the...
