Description
Technical Field
The invention relates to the technical field of computers, in particular to a method and a device for server heat dissipation.
Background
In the existing server design, fans or water cooling and the like are mostly adopted as heat dissipation systems.
The cooling system can regulate and control the rotating speed of a fan or the flow rate of water according to the temperature of each component, namely a component PID (proportion-integral-derivative) regulation mode, a sensor linear regulation mode or two parallel regulation modes are adopted. The mode based on component PID regulation is to regulate the fan speed or water flow rate based on the temperature of the component, and the mode based on sensor linear regulation is to regulate the fan speed or water flow rate based on the inlet air temperature.
In the process of implementing the invention, the inventor finds that at least the following problems exist in the prior art:
1. the temperature of the component can be reported by mistake or have a fault, and the real temperature condition of the component cannot be accurately obtained only based on temperature regulation, so that regulation and control misoperation is easily caused;
2. some parts cannot feed back temperature by themselves, and the full-load operation condition is usually defaulted in a regulation strategy for the heat dissipation of the parts, so the setting of the rotating speed of a fan or the water flow rate is higher;
3. the inlet air temperature is usually only one server inlet air temperature, once the abnormal common method is that a fan or water flow directly runs at full speed, the power consumption and the noise are high;
4. if the two regulation and control modes are adopted simultaneously, the highest rotating speed obtained by the two modes is taken to set the rotating speed of the fan or the water flow rate, and the rotating speed of the fan or the water flow rate is higher, so that the power is increased and the electric energy is wasted.

Detailed Description
Exemplary embodiments of the present invention are described below with reference to the accompanying drawings, in which various details of embodiments of the invention are included to assist understanding, and which are to be considered as merely exemplary. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the invention. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.
It should be noted that the embodiments of the present invention and the technical features of the embodiments may be combined with each other without conflict.
According to the server heat dissipation method, the regulation and control modes are graded, and the rotating speed or the water flow rate of the fan is regulated step by step based on the conditions of the temperature of the heating device, the power consumption of the heating device, the inlet temperature and the like, so that the condition that regulation and control misoperation, the rotating speed or the water flow rate of the fan is set to be higher, or the fan or the water flow runs at full speed due to the abnormal feedback of the temperature of the heating device or the temperature of the inlet is avoided, the adjustment of the heat dissipation system as required is realized, the power of the heat dissipation system is reduced, and the electric energy is saved.
Fig. 1 is a schematic diagram of main steps of a method for dissipating heat of a server according to an embodiment of the present invention. As shown in fig. 1, the method for dissipating heat of a server according to the embodiment of the present invention mainly includes the following steps:
step S101: and monitoring the real-time temperature of the heating device, and adjusting the rotating speed or the flow rate of the heat dissipation system based on the temperature deviation value between the real-time temperature and the expected temperature.
Generally, the higher the load of a server is, the higher the temperature of a heating device in the server is, the heat dissipation system is utilized to dissipate heat and cool the heating device, so that the server can run quieter, the efficiency is higher, and the stability is more reliable. The heat dissipation system may be a fan or a water cooling system, etc. When the rotating speed or the flow rate of the heat dissipation system is adjusted, the real-time temperature of the heating device is firstly compared with the expected temperature, if the real-time temperature is higher than the expected temperature (the temperature deviation value is positive), the rotating speed or the flow rate of the heat dissipation system is increased, if the real-time temperature is equal to the expected temperature (the temperature deviation value is zero), the rotating speed or the flow rate of the heat dissipation system is not adjusted, if the real-time temperature is lower than the expected temperature (the temperature deviation value is negative), the rotating speed or the flow rate of the heat dissipation system is reduced, a fan or water flow runs at a lower speed under the condition of meeting the heat dissipation requirement, and when the server is in a lower load, the adjusting mode is more energy-saving. It should be noted that the desired temperature may be set according to actual conditions or historical data. When the server is provided with a plurality of heating devices, the real-time temperature of one heating device can be selected to calculate the temperature deviation value, and the value of the expected temperature is correspondingly set to correspond to one heating device; it is also possible to calculate a temperature deviation value by superimposing the real-time temperatures of all the heat generating devices, and accordingly, the value of the desired temperature is set as the corresponding server.
In the embodiment of the present invention, step S101 may be implemented by the following steps: monitoring the real-time temperature of the heating device by using a temperature sensor; acquiring a real-time temperature, and calculating a temperature deviation value between the real-time temperature and an expected temperature; and adjusting the rotating speed or the flow rate of the heat dissipation system by adopting a PID control technology based on the temperature deviation value so as to enable the real-time temperature to approach the expected temperature.
The real-time temperature of the heating device can be actively reported by the heating device, and can also be monitored by a temperature sensor. A temperature sensor is a sensor that senses temperature and converts it into a usable output signal. The real-time temperature of the heating device can be monitored through the temperature sensor. When the cooling system is regulated and controlled based on the temperature deviation value, the rotating speed or the flow rate of the cooling system can be regulated by adopting a PID control technology. PID control technology: the control amount is calculated by using the proportion, the integral and the derivative so that the target value tends to a desired value. The server heat dissipation method of the embodiment of the invention presets a desired temperature, monitors the real-time temperature of each heating device, calculates the temperature deviation value between the real-time temperature and the desired temperature, outputs a correction value (namely the amount to be adjusted) based on the temperature deviation value, and adjusts the rotating speed or the flow speed of the heat dissipation system according to the correction value, thereby adjusting the real-time temperature of the heating devices to reduce the temperature deviation value, and finally enabling the real-time temperature of all the heating devices to finally approach the desired temperature.
Step S102: and when the real-time temperature feedback is abnormal, acquiring the real-time power consumption of the heating device, and adjusting the rotating speed or the flow rate of the cooling system based on the power consumption deviation value of the real-time power consumption and the expected power consumption.
When the real-time temperature feedback of the heating device is abnormal, the heat dissipation condition of the heating device or the server cannot be accurately known, at the moment, the server heat dissipation method can also obtain the real-time power consumption of the heating device, wherein the power consumption refers to the heat energy dissipated by the heating device in the working process, generally, the higher the load of the heating device is, the higher the real-time power consumption is, the higher the temperature is, and the real-time power consumption of the heating device can reflect the heat dissipation requirement of the heating device, so the rotating speed or the flow speed of a heat dissipation system can be adjusted according to the power consumption deviation value between the real-time power consumption of the heating device and the expected power consumption, a fan or water flow runs at a lower speed under the condition of meeting the heat dissipation requirement, and when the server is at a lower load, the regulation mode is more energy-saving. That is, if the real-time power consumption is greater than the expected power consumption (the power consumption deviation value is positive), the rotation speed or the flow speed of the heat dissipation system is increased, if the real-time power consumption is equal to the expected power consumption (the power consumption deviation value is zero), the rotation speed or the flow speed of the heat dissipation system is not adjusted, and if the real-time power consumption is less than the expected power consumption (the power consumption deviation value is negative), the rotation speed or the flow speed of the heat dissipation system is reduced. It should be noted that the expected power consumption may be set according to actual conditions or historical data. When the server is provided with a plurality of heating devices, the real-time power consumption of one heating device can be selected to calculate the power consumption deviation value, and the expected power consumption value is correspondingly set to correspond to one heating device; the power consumption deviation value may also be calculated by superimposing the real-time power consumptions of all the heat generating devices, and accordingly the value of the expected power consumption is set as the corresponding server.
For the determination of the real-time temperature feedback abnormality, in the embodiment of the invention, the real-time temperature of the heating device can be inquired periodically; and if the feedback cannot be obtained or the feedback is unavailable, judging that the real-time temperature feedback of the heating device is abnormal. For example, when the real-time temperature of a certain heating device is inquired, the feedback of the temperature sensor or the heating device cannot be obtained, or the value fed back by the temperature sensor or the heating device has no practical significance (the temperature value fed back is not in the normal interval), the real-time temperature feedback of the heating device is judged to be abnormal.
In the embodiment of the present invention, step S102 may be implemented by the following steps: when the real-time temperature feedback is abnormal, acquiring the real-time power consumption of the heating device, and calculating the power consumption deviation value of the real-time power consumption and the expected power consumption; and adjusting the rotating speed or the flow rate of the heat dissipation system by adopting a PID control technology based on the power consumption deviation value.
The real-time power consumption of the heating device can be actively reported by the heating device, and can also be obtained by inquiring and converting the load of the heating device. When the cooling system is regulated and controlled based on the power consumption deviation value, the rotating speed or the flow rate of the cooling system can be regulated by adopting a PID control technology. The server heat dissipation method of the embodiment of the invention presets a desired power consumption, monitors the real-time power consumption of each heating device, calculates the power consumption deviation value between the real-time power consumption and the desired power consumption, outputs a correction value (namely the amount to be adjusted) based on the power consumption deviation value, and adjusts the rotating speed or the flow rate of the heat dissipation system according to the correction value. It should be noted that, although the real-time power consumption of all the heat generating devices cannot finally approach the expected power consumption after the rotation speed or the flow rate of the heat dissipating system is adjusted according to the correction value, the real-time temperature of the heat generating devices can be accurately adjusted.
Step S103: when the real-time power consumption feedback is abnormal, the server inlet temperature and the mainboard inlet temperature are obtained, and the rotating speed or the flow speed of the heat dissipation system is adjusted based on the server inlet temperature or the mainboard inlet temperature.
When the real-time power consumption feedback of the heating device is abnormal, the heat dissipation condition of the heating device or the server cannot be accurately known, and at the moment, the rotating speed or the flow speed of the heat dissipation system can be adjusted according to the inlet temperature of the server or the rotating speed or the flow speed of the heat dissipation system can be adjusted according to the inlet temperature of the mainboard.
It should be noted that the server inlet refers to an inlet where wind or water enters the server, such as a mounting position of a fan; the main board inlet refers to a position where wind or water flows through the main board.
For the determination of the real-time power consumption feedback abnormality, in the embodiment of the invention, the real-time power consumption of the heating device can be inquired periodically; and if the feedback cannot be obtained or the feedback is unavailable, judging that the real-time power consumption feedback of the heating device is abnormal.
In the embodiment of the present invention, step S103 may be implemented by the following steps: monitoring the temperature of a server inlet by using a server inlet sensor and monitoring the temperature of a mainboard inlet by using a mainboard inlet sensor; when the real-time power consumption feedback of the heating device is abnormal, acquiring the inlet temperature of the server and the inlet temperature of the mainboard, and fitting the linear relation between the inlet temperature of the server and the inlet temperature of the mainboard; adjusting the rotating speed or flow rate of the heat dissipation system by adopting a linear control technology based on the inlet temperature of the server; and when the server inlet temperature feedback is abnormal, adjusting the rotating speed or the flow rate of the heat dissipation system by adopting a linear control technology based on the linear relation and the mainboard inlet temperature.
When the real-time temperature and the real-time power consumption of the heating device are both fed back abnormally, the PID control technology is not adopted for adjusting the heat dissipation system, and the linear control technology is adopted for adjusting the heat dissipation system. The linear control technology comprises the following steps: the heat dissipation is to take the heat in the server out of the server, and finally to reduce the temperature in the server to a certain value or not higher than the certain value. If the required heat and time are fixed, the higher the inlet temperature is, the higher the required rotating speed or flow speed is, so that the inlet temperature and the rotating speed or flow speed of the heat dissipation system are in a linear relation, and the rotating speed or flow speed of the heat dissipation system can be determined according to the inlet temperature value.
Fitting: figuratively, a series of points on a plane are connected by a smooth curve, which has numerous possibilities, and a generally fitted curve can be represented by a function. The server inlet temperature and the mainboard inlet temperature are in a nearly linear relation on the premise of stable pressure, the server inlet temperature is represented by the mainboard inlet temperature, the difference curve of the two temperatures under different environment temperatures and different system loads can be actually measured, and the curve is formulated in a mathematical mode. The server heat radiation method can respectively fit the server inlet temperature and the mainboard inlet temperature to obtain two curves corresponding to the server inlet temperature and the mainboard inlet temperature, and obtain the linear relation between the server inlet temperature and the mainboard inlet temperature according to the two curves, namely the server inlet temperature can be predicted according to the mainboard inlet temperature, so that when the server inlet temperature is fed back abnormally, the server inlet temperature can be predicted according to the mainboard inlet temperature, and further, the rotating speed or the flow speed of a heat radiation system can be determined to be adjusted.
The server inlet sensor and the motherboard inlet sensor may be temperature sensors. In addition, regarding the determination of the abnormal feedback of the server inlet temperature, a mode of periodically inquiring the server inlet temperature can be adopted, and if the feedback is not obtained or an abnormal value is fed back, the abnormal feedback of the server inlet temperature is judged.
In the embodiment of the present invention, the method for dissipating heat of the server may further include: inquiring the temperature of the inlet of the mainboard at regular intervals; if the feedback or the feedback abnormal value is not obtained, judging that the temperature feedback of the main board inlet is abnormal; when the temperature feedback of the mainboard is abnormal, the rotating speed or the flow speed of the heat dissipation system is adjusted to the maximum value.
When all indexes such as the temperature of the mainboard inlet are abnormal, the heat dissipation system can run at full speed in order to ensure good running of the server.
According to the server heat dissipation method, the real-time temperature of the heating device is obtained, and the rotating speed or the flow speed of the heat dissipation system is adjusted based on the temperature deviation value between the real-time temperature and the expected temperature; when the real-time temperature feedback is abnormal, acquiring the real-time power consumption of the heating device, and adjusting the rotating speed or the flow rate of the heat dissipation system based on the power consumption deviation value of the real-time power consumption and the expected power consumption; when the real-time power consumption feedback is abnormal, the server inlet temperature and the mainboard inlet temperature are obtained, the rotating speed or the flow speed of the heat dissipation system is adjusted based on the server inlet temperature or the mainboard inlet temperature, the adjusting and controlling mode of the heat dissipation system is classified, the problem that the adjusting and controlling misoperation is easily caused is solved, the setting of the rotating speed or the flow speed of a fan is higher, the power consumption and the noise are higher, the technical problem of wasting electric energy is solved, the step-by-step adjusting and controlling of the heat dissipation system is further achieved, the adjustment on the heat dissipation system as required is achieved, the adjusting and controlling misoperation is avoided, the power and the noise of the heat dissipation system are reduced, and the technical effect of saving electric energy is achieved.
Fig. 2 is a schematic diagram of regulation mode classification of a method for server heat dissipation according to an embodiment of the present invention.
As shown in fig. 2, the method for server heat dissipation according to the embodiment of the present invention divides the regulation mode into five levels:
a first stage: regulating and controlling based on the real-time temperature of the heating device;
and a second stage: regulating and controlling based on the real-time power consumption of the heating device;
and a third stage: regulating and controlling based on the inlet temperature of the server;

It should be noted that, the first stage and the second stage adopt PID control technology to adjust the heat dissipation system, the third stage and the fourth stage adopt linear control technology to adjust the heat dissipation system, and the fifth stage does not limit the fan speed or the water flow rate of the heat dissipation system.

The method for radiating the server can be executed by a Baseboard Management Controller (BMC), wherein the BMC is a special service processor for executing remote management control of the server and can perform operations such as firmware upgrading, checking or controlling on the server.
