All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
At present, server cabinets in a cloud computing data center are independent, related technologies also provide that the temperature of a single server is monitored by using a sensor, heat dissipation operation is carried out on the server cabinets based on the monitored temperature value, and a heat radiator is kept running when the temperature of the server reaches a certain condition. Although this heat dissipation method can prevent unnecessary idling to some extent and reduce the power consumption of the heat sink as compared with a heat dissipation method that keeps the heat sink operating all the time, the inventors have found that this method still has the following drawbacks:
(1) The heat exchange between the server cabinet and a contact medium in a machine room is realized by the heat dissipation device of the server cabinet, but the related technology only detects the temperature of a single server, so that the heat dissipation of the cabinet is carried out by taking the temperature as a reference, the condition of starting the heat dissipation is not accurate, and the possibility of wasting power resources or untimely heat dissipation is caused;
(2) In the related technology, the specific situation that the server cabinet needs to dissipate heat is not considered, but a radiator with fixed power is used for dissipating heat of the server cabinet, so that the possibility of untimely heat dissipation is provided under the high-temperature condition of the server cabinet, and the possibility of wasting power resources is provided under the low-temperature condition of the server cabinet;
(3) Because the server needs to judge and calculate whether heat dissipation is carried out or not, each server cabinet needs to be provided with independent electronic equipment containing a calculation chip, and higher requirements are put forward on the cost;
(4) The heat dissipation of each server cabinet is independent, and managers of the data center are not convenient to know the heat dissipation conditions of all the server cabinets in the data center, and are not favorable for collective heat dissipation debugging and management.
Based on the analysis of the above problems, embodiments of the present application provide a method for controlling heat dissipation of a server cabinet, a system for controlling heat dissipation of a server cabinet, a readable storage medium and an electronic device, which utilize the advantage of communication connection between a cloud platform and a server, can precisely control heat dissipation of a server cabinet where a server in communication connection with the cloud platform is located, comprehensively consider the temperature of the server cabinet and the room temperature of a machine room where the server cabinet is located, determine whether a heat dissipation device of a target server cabinet needs to be started, further determine the operating power of the heat dissipation device, and allow the heat dissipation device to dissipate heat of the server cabinet with the power, so as to meet the requirements of the server on heat dissipation in the current operating state and the environmental state, avoid waste of electric power caused by directly dissipating heat with the rated maximum power, further save electric power resources, and help to prolong the service life of the heat dissipation device.
The embodiments of the present application will be described below with reference to the drawings.
Referring to fig. 1, fig. 1 is a technical environment configuration diagram for controlling heat dissipation of a server cabinet according to an embodiment of the present application. As shown in fig. 1, the cloud platform may establish a remote communication connection with a preset server communication host, where the preset server communication host may be located in the same machine room as the target server cabinet. One machine room at least comprises one server cabinet, and the server cabinet at least comprises one server.
The preset server communication host is located locally in the server data center, and the temperature of the target server cabinet and the room temperature of the machine room where the target server cabinet is located can be obtained through the temperature sensor.
The preset server communication host can respond to a control command sent by the cloud platform and control the heat dissipation devices in the server cabinets. The controlling includes at least one of: and controlling to start, close and work at the target power.
Referring to fig. 2, fig. 2 is a flowchart illustrating steps of a method for controlling heat dissipation of a server cabinet according to an embodiment of the present application. As shown in fig. 2, an embodiment of the present application provides a method for controlling heat dissipation of a server cabinet, where the method may be applied to a cloud platform, and the cloud platform establishes a communication connection with a server, including the following steps:
and S31, determining the current target server cabinet to be detected.
In the embodiment of the application, the target server cabinet to be detected currently can be determined by confirming the server placed in the cloud platform and the target server cabinet.
The target server cabinet to be detected may be a server cabinet in which any server among all servers that have established communication connection with the cloud platform is located.
Through this embodiment, utilize the communication connection advantage between cloud platform and the server, detect the radiating server rack of needs control, can aim at ground and carry out accurate control to the heat dissipation of the server rack at the server place that establishes communication connection with the cloud platform.
And S32, obtaining the temperature of the target server cabinet and the room temperature of the machine room where the target server cabinet is located.
The temperature of the target server cabinet can be obtained by a temperature sensor preset inside or outside the target server cabinet. The room temperature of the machine room where the target server cabinet is located can be obtained through a temperature sensor which is arranged in the machine room where the target server cabinet is located in advance.
The present embodiment is not limited to the type of the temperature sensor, and a non-contact type thermal resistance temperature sensor, a thermocouple temperature sensor, an infrared temperature sensor, or the like may be specifically used.
Furthermore, the temperature sensor can transmit the temperature signal carrying the temperature of the target server cabinet and the room temperature of the machine room where the target server cabinet is located to a preset server communication host in a data center in real time, and the server host periodically transmits the updated temperature signal to the cloud platform, so that the cloud platform can periodically obtain the updated temperature of the target server cabinet and the room temperature of the machine room where the target server cabinet is located.
The preset server communication host may be any one or more of all server hosts in the data center, and the preset server communication host establishes communication connection with the cloud platform in advance. The number of the preset server communication hosts may be set according to the communication capability and the calculation capability of the preset server communication hosts.
And S33, determining whether the heat dissipation device of the target server cabinet needs to be started or not according to the temperature of the target server cabinet and the room temperature of the machine room.
Considering that the heat dissipation is needed after the temperature of the target server cabinet reaches a high enough value; and, the higher the room temperature of the machine room, that is, the higher the temperature of the contact medium for exchanging heat with the server rack, the deterioration of the heat dissipation effect is caused, and therefore, the room temperature of the machine room reaches a sufficiently high value, and heat dissipation is also required.
Therefore, in this embodiment of the application, the cloud platform may determine that the heat dissipation device of the target server cabinet needs to be started when the temperature of the target server cabinet is higher than a preset value and when the room temperature of the machine room is also higher than a preset value.
For example, it may be determined that the heat sink of the target server cabinet needs to be activated if the temperature of the target server cabinet is higher than 30 ℃ and if the room temperature of the machine room is higher than 25 ℃.
The heat dissipation device of the target server cabinet can be a device for directly dissipating heat of the target server cabinet body, and exemplarily can be a liquid cooling heat dissipation device which is arranged on the target server cabinet and connected with a solid contact medium outside the cabinet, so that heat exchange with the server cabinet is realized by utilizing contact media such as ground, a wall, a steel frame and air in a machine room. The heat dissipation device of the target server cabinet may also be a device for directly dissipating heat of the internal space and structure of the target server cabinet, and may exemplarily be an air-cooled heat dissipation device arranged on the target server cabinet so as to realize heat exchange with the server cabinet by using contact media such as air in a machine room.
Through this embodiment, can be based on cloud platform's communication ability and computing power, the temperature of considering server rack and the room temperature of place comprehensively, judge whether the heat abstractor of target server rack needs to start, avoided not needing carrying out invalid heat dissipation under the radiating condition, saved electric power resource, help prolonging heat abstractor's life.
And S34, determining target power according to the temperature of the target server cabinet and the room temperature of the machine room under the condition that the heat dissipation device of the target server cabinet needs to be started.
In this embodiment of the application, under the condition that the heat dissipation device of the target server cabinet needs to be started, the cloud platform may control the heat dissipation device of the target server cabinet to be started through a preset server communication host. The cloud platform can control the heat dissipation devices of all server cabinets in the data center which is in communication connection with the cloud platform through the preset server communication host, and then control the heat dissipation devices of the target server cabinets. The heat dissipation device of the target server cabinet can be in communication control connection with the preset server communication host in advance, and can respond to a starting control command of the preset server communication host.
Considering that the higher the temperature of the target server cabinet is, the more heat dissipation is needed, and the higher the heat dissipation requirement is put forward; and, the higher the room temperature of the machine room, that is, the higher the temperature of the contact medium for exchanging heat with the server rack, the higher the heat dissipation effect is, and therefore, the higher the room temperature of the machine room, the more powerful heat dissipation is also required.
Therefore, in this embodiment of the application, the cloud platform may determine the target power according to the temperature of the target server cabinet and the room temperature of the room, where the target power may be positively correlated with the temperature of the target server cabinet, and the target power may also be negatively correlated with the room temperature of the room. It can be said that the higher the temperature of the target server cabinet is, the higher the target power is; the higher the room temperature of the machine room, the higher the target power.
In addition, the temperature of the target server cabinet and the room temperature of the machine room are used as the basis for selecting the target power. Illustratively, in the case that the temperature of the target server cabinet is 40 ℃ and the room temperature of the machine room is 20 ℃, the target power is selected to be 10W; selecting the target power to be 10W under the conditions that the temperature of the target server cabinet is 35 ℃ and the room temperature of a machine room is 25 ℃; in the case where the temperature of the target server cabinet is 40 ℃, and the room temperature of the machine room is 25 ℃, the target power is selected to be 20W.
And S35, controlling a heat dissipation device of the target server cabinet to dissipate heat of the target server cabinet according to the target power.
The heat dissipation device of the target server cabinet can be a heat dissipation device capable of selecting multi-gear power output, and each gear corresponds to different target power. The heat dissipation device of the server cabinet can also be a heat dissipation device which realizes stepless power regulation according to set power.
Further, under different target powers, the heat dissipation capability and the heat dissipation effect of the heat dissipation device of the target server cabinet are also different. The higher the target power is, the stronger the heat dissipation capacity of the heat dissipation device of the target server cabinet is, and the better the heat dissipation effect is. Specifically, the higher the target power is, the faster the liquid circulation speed of the liquid cooling heat dissipation device is, and the higher the rotation speed of the fan blades of the air cooling heat dissipation device is, both of which can bring about the improvement of the heat dissipation effect.
In this embodiment of the application, the cloud platform may control the heat sinks of all server cabinets in the data center that establishes communication connection with the cloud platform through the preset server communication host, so as to control the heat sink of the target server cabinet. The heat dissipation device of the target server cabinet can be in communication control connection with the preset server communication host in advance, and can respond to a power control command of the preset server communication host.
Through the embodiment, the operating power of the heat dissipation device can be determined according to the temperature of the server cabinet and the room temperature of the machine room where the server cabinet is located based on the communication capacity and the computing capacity of the cloud platform, so that the heat dissipation of the server cabinet is realized by the power, the requirements for heat dissipation under the current operating state and the environmental state of the server are met, the waste of electric power caused by direct heat dissipation with rated maximum power is avoided, the electric power resource is further saved, and the service life of the heat dissipation device is prolonged.
Considering that the room temperature change of a computer room provides a smaller change for heat dissipation, and a cloud platform may need to process heat dissipation of server cabinets in thousands of data centers, in order to further reduce the amount of computation, the present application provides a method for simplifying the room temperature condition of the computer room when determining whether to start a heat dissipation device, and for this reason, in an optional implementation manner, the present application further provides a method for determining whether the heat dissipation device needs to be started, including:
and S331, determining that the heat dissipation device of the target server cabinet needs to be started under the condition that the temperature of the target server cabinet is higher than a first preset temperature value and the room temperature of the machine room is higher than the first preset temperature value.
When judging whether to start the heat abstractor, the embodiment of the application divides the room temperature of the machine room into two conditions, and the room temperature of the machine room is higher than the first preset temperature value, and at the moment, the room temperature of the machine room already puts forward a certain requirement on heat dissipation, and when the temperature of the target server cabinet is higher than the first preset temperature value, the heat abstractor of the target server cabinet is determined to be started.
The first preset temperature value is an initial cabinet temperature value at which the heat dissipation device should start dissipating heat when the room environment is higher than the first preset temperature value, and the first preset temperature value can be obtained by fitting analysis according to multiple heat dissipation tests of the server cabinet. And may be, for example, one of the values between 20 c and 25 c.
S332, determining that the heat dissipation device of the target server cabinet needs to be started under the condition that the temperature of the target server cabinet is higher than a second preset temperature value and the room temperature of the machine room is not higher than a first preset temperature value; wherein the second preset temperature value is greater than the first preset temperature value.
The second preset temperature value is an initial cabinet temperature value at which the heat dissipation device should start dissipating heat when the room environment is not higher than the first preset temperature value, and can also be obtained by fitting analysis according to multiple heat dissipation tests of the server cabinet. Illustratively, it may be one of the values between 30 ℃ and 35 ℃.
The method comprises the steps that a heat dissipation device of a target server cabinet is started when the temperature of the target server cabinet is higher than a second preset temperature value, and the second preset temperature value is larger than the first preset temperature value.
For example, when the temperature of a target server cabinet is higher than 20 ℃ and the room temperature of the machine room is higher than 20 ℃, it is determined that a heat dissipation device of the target server cabinet needs to be started; and under the condition that the temperature of the target server cabinet is higher than 25 ℃ and the room temperature of the machine room is not higher than 20 ℃, determining that the heat dissipation device of the target server cabinet needs to be started.
Through this embodiment, consider that the room temperature of computer lab is less to the heat dissipation influence dynamics, simplify the room temperature's of computer lab condition to judge whether start heat abstractor, further reduced cloud platform's data processing and calculated volume, help improving computational efficiency.
The foregoing embodiment realizes the processing of starting different heat dissipation devices under different room temperature conditions, and the embodiment of the present application further considers the setting of different target powers under different room temperature conditions. To this end, in an alternative embodiment, the present application further provides a method of determining a target power, comprising:
s341, determining the target power having the first positive correlation with the temperature of the target server cabinet under the condition that the room temperature of the machine room is higher than the first preset temperature value.
Specifically, with reference to the foregoing embodiment, when the room temperature of the machine room is higher than the first preset temperature value, the target power starts to have a positive correlation with the temperature of the target server cabinet after the temperature of the target server cabinet is higher than the first preset temperature value.
And S342, determining the target power with the second positive correlation relation with the temperature of the target server cabinet under the condition that the room temperature of the machine room is not higher than the first preset temperature value.
Specifically, with reference to the foregoing embodiment, under the condition that the room temperature of the machine room is not higher than the first preset temperature value, after the temperature of the target server cabinet is higher than the second preset temperature value, the target power starts to have a positive correlation with the temperature of the target server cabinet, which is dynamically changed.
Furthermore, considering that the maximum rated power of the heat sink is a finite value, in the process of determining the target power by positive correlation in the two cases, the temperature of the target server cabinet required by the maximum rated power of the heat sink varies differently, and when the room temperature of the computer room is higher than the first preset temperature value, the temperature of the server cabinet varies more greatly than when the room temperature of the computer room is not higher than the first preset temperature value, so that the correlation coefficient of the first positive correlation may be lower than the correlation coefficient of the second positive correlation.

S42, under the condition that the temperature of the target server cabinet is not higher than a second preset temperature value and the room temperature of the machine room is not higher than a first preset temperature value, closing a heat dissipation device of the target server cabinet; wherein the second preset temperature value is greater than the first preset temperature value.
The method comprises the steps that when the temperature of a target server cabinet is not higher than a second preset temperature value, the heat dissipation device of the target server cabinet is determined to be closed, and the second preset temperature value is larger than the first preset temperature value.
Through this embodiment, consider that the room temperature of computer lab is less to the heat dissipation influence dynamics, simplify the room temperature's of computer lab condition to whether judge and close heat abstractor, further reduced cloud platform's data processing and calculated volume, help improving computational efficiency.
