Fig. 4 is a schematic diagram of a fan speed control device of an air-cooled server, where fig. 4 includes a BMC control management chip, a CPLD logic implementation chip, a connector for a fan and a device, and so on.
Because the BMC needs a certain time to start, during the BMC starting, the rotating speed of the fan cannot be adjusted and can only be carried out in a full-speed rotating mode, and the noise is very high, the data strobe MUX is arranged in the mainboard CPLD, and the state detection of the BMC is realized through the waveform output by the watchdog of the BMC. Specifically, if the square wave is output, the BMC normally works, and at this time, the gate is switched on to a first rotational speed control register (working PWM register), further, the BMC can output a duty ratio to the first rotational speed control register of the CPLD through a SMB_I2C11_PLD channel, wherein the duty ratio is the duty ratio obtained by the BMC according to the acquired temperature information of the temperature sensor, and TACH information of the fan in a CPLD FAN TACH register (rotational speed monitoring module) is acquired through the channel, so that the fan state is monitored. When the BMC is in the start-up phase and cannot normally output square waves, the motherboard CPLD controls the gating device to gate to a second rotational speed control register (FIXED rotational speed control register), and at this time, the rotational speed of the fan is controlled by the duty cycle output by the FIXED PWM register, and the FIXED PWM register is a FIXED value PWM selection table set according to the on-site condition (DEVICE PRESENT) of the connector of the device, and the number of PWM values selectable in the selection table depends on the configuration developed by the server. Taking the configuration of only the OCP network card and the GPU as an example except the PCIE standard card, when the DEVICE is in place, the corresponding CPLD GPIO is pulled to GND by hardware, and the fixed PWM selection table references table 1.
TABLE 1
According to the selection of the duty ratio in table 1, it can be ensured that the rotation speed of the fan can be controlled by selecting a fixed PWM value according to the configuration during the period that the BMC does not enter normal operation, high decibel noise caused by too high rotation speed of the fan under the condition that the fan cannot be controlled in a full rotation state is avoided, and electric energy consumption is saved for users. According to the method and the device, high decibel noise generated by high-speed rotation of the fan when the server is started during abnormal operation of the BMC is greatly reduced, good experience of a user in the use process is greatly enhanced, and the use comfort of the product is improved; the invention effectively reduces the waste of electric energy of the server during the use and starting, reduces the electric charge support for the client and simultaneously reduces the pollution to the environment.

In this embodiment, after the data gate is gated to the first rotational speed control register, the baseboard management controller determines a first duty ratio according to the acquired temperature sensor information and outputs the first duty ratio to the first rotational speed control register, so as to accurately control the rotational speed of the fan by the first duty ratio.
Step S13: and after the data strobe is detected to be strobed by the data strobe, determining a second duty ratio based on the in-place condition of connectors of all devices in the air cooling server, and controlling the rotating speed of the fan according to the second duty ratio.
In this embodiment, after detecting that the data strobe device is strobed, determining the second duty ratio based on the in-place situation of the connectors of each device in the air-cooled server, and controlling the rotational speed of the fan according to the second duty ratio specifically includes: when the data strobe is detected to be strobed by the data strobe, determining the second duty ratio by using a preset duty ratio selection table, and controlling the rotating speed of the fan according to the second duty ratio; the preset duty ratio selection table sets a corresponding relation between the in-place condition of connectors of different devices and the second duty ratio, where the connectors of the devices include, but are not limited to, an OCP (Open Compute Project, open source server hardware) network card, a GPU (Graphics processing unit, a graphics processor), a PCIE (high-speed serial computer expansion bus standard) label card, and the like.
In summary, the present application not only can control the rotational speed of the fan by the complex programmable logic device during the startup of the baseboard management controller, but also can completely take over the control right of the rotational speed of the fan when the baseboard management controller fails, and the rotational speed of the fan is controlled by the complex programmable logic device.
As can be seen, the present application provides a method for controlling a fan rotation speed of an air-cooled server, including: when the baseboard management controller is in a normal working state, the data gate is controlled to gate to a first rotating speed control register, and when the baseboard management controller is in a starting state, the data gate is controlled to gate to a second rotating speed control register; after the data strobe device is strobed to the first rotating speed control register, determining a first duty ratio according to the acquired temperature sensor information, and controlling the rotating speed of the fan according to the first duty ratio and the first rotating speed control register; and after the data strobe is detected to be strobed by the data strobe, determining a second duty ratio based on the in-place condition of connectors of all devices in the air cooling server, and controlling the rotating speed of the fan according to the second duty ratio. In summary, in the baseboard management controller in the present application, during the startup period, the data strobe device will strobe to the second rotational speed control register, the second rotational speed control register determines the second duty ratio based on the in-place condition of the connectors of each device in the air cooling server, and further controls the rotational speed of the fan according to the second duty ratio, that is, the fan can rotate according to the in-place condition of the connectors of the devices rather than in the full-speed full-rotation state, thus, the high db noise generated by the high-speed rotation of the fan during the startup period of the baseboard management controller is greatly reduced, the good experience of the user in the use process is greatly enhanced, and the waste of the electric energy of the baseboard management controller during the startup period is effectively reduced.
