Detailed Description

The present application will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present application more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the application.

In one embodiment, as shown in fig. 1, a heat dissipation method is provided, and an embodiment of the present application is described by taking a BMC (Board Management Controller, baseboard management controller) applied to a server as an example, where an execution device of the heat dissipation method is not limited, and includes the following steps 102 to 106:

And 102, under the condition that the internal temperature of the server is abnormal, determining a target fan according to the partition configuration data.

The partition configuration data comprises the association relation between each temperature sensor and each fan in the server and each fan domain. Each fan domain includes fans in the same enclosed area.

In an implementation, the BMC obtains the temperature of each temperature sensor within the server. If the temperature of the target temperature sensor is larger than a preset temperature threshold, the BMC determines that the internal temperature of the server is abnormal. Under the condition that the internal temperature of the server is abnormal, the BMC determines a target fan with an association relation with a target temperature sensor according to the partition configuration data.

In an exemplary embodiment, after the server is powered on, the BMC initializes various services and starts a heat dissipation and speed regulation process. The heat dissipation and speed regulation process can preload partition configuration data in a Json (JavaScript Object Notation, a lightweight data exchange format) configuration file and heat dissipation and speed regulation parameters into a program structure body for use in subsequent logic. And the normal heat dissipation speed regulation logic and the heat dissipation partition disaster recovery function under abnormal conditions are realized through the heat dissipation speed regulation process.

Step 104, determining an adjustment fan in the server based on the partition configuration data, the status data of the target fan, and the type of the target fan.

In an implementation, the BMC obtains status data of the target fan and a type of the target fan. Then, the BMC judges whether the state data of the target fan represents the state of the target fan to be normal or not. If the state data of the target fan indicates that the target fan is normal, the BMC determines to adjust the fan in the server according to the type of the target fan. If the state data of the target fan indicates that the target fan is abnormal, the BMC determines to adjust the fan in the server according to the type of the target fan and each fan domain.

And 106, controlling the adjusting fan to perform heat dissipation control according to the target rotating speed.

In implementation, the BMC is preset with a heat dissipation speed regulation parameter. The BMC determines and adjusts the target rotating speed corresponding to the fan through configuring and adjusting the heat dissipation speed regulation parameter, and adjusts the wind speed of the fan to the target rotating speed so as to realize heat dissipation of the server.

In one exemplary embodiment, partition configuration data is constructed prior to determining the target fan based on the partition configuration data. As shown in fig. 2, the specific processing procedure of the heat dissipation method further includes steps 202 to 206 before the step 102 is performed. Wherein:

Step 202, grouping the fans based on the position data of the fans in the server to obtain the fan domains.

In an implementation, the BMC obtains location data for each fan and configuration data for the server. And dividing each fan belonging to the same closed space into the same fan domain according to the position data of each fan and the structure data of the server by the BMC to obtain each fan domain.

Step 204, establishing an association relationship between each fan and each temperature sensor according to the position data of each fan and the position data of each temperature sensor.

In implementation, the BMC determines, for each fan, a temperature sensor close to each fan according to the position data of the fan and the position data of each temperature sensor, and establishes an association relationship between the temperature sensor and the fan.

Optionally, the association relationship between the temperature sensor and the fan may be adaptively adjusted according to the changes of the circuit and the structure in the server, and the establishment condition of the association relationship is not limited in the embodiment of the present application.

Step 206, constructing partition configuration data based on each fan domain and each association relationship.

In an implementation, the BMC builds partition configuration data based on each fan domain and each association.

In an exemplary embodiment, it is necessary to monitor whether the internal temperature of the server is normal based on the temperature of each temperature sensor in the server. As shown in fig. 3, the specific process of the heat dissipation method further includes steps 302 to 304 before the step 102 is performed. Wherein:

step 302, the temperature of each temperature sensor in the server is obtained, and whether the temperature of each temperature sensor exceeds a preset temperature threshold is determined.

In practice, a temperature threshold is preset in the BMC. The BMC acquires temperature data of each temperature sensor in the server. Then, the BMC judges whether the temperature data of each temperature sensor exceeds a preset temperature threshold value, so as to determine whether the temperature data detected by the temperature sensor is normal.

Optionally, the temperature threshold is set according to a heat dissipation requirement, and the embodiment of the application does not limit the temperature threshold.

And step 304, if the temperature of the temperature sensor exceeds the temperature threshold, determining the temperature sensor as a target temperature sensor, and determining that the internal temperature of the server is abnormal.

In practice, if the temperature of the temperature sensor exceeds the temperature threshold, the BMC determines the temperature sensor as the target temperature sensor. The BMC then determines that the server internal temperature is abnormal.

In the embodiment, the heat dissipation condition of the server is defined by monitoring the temperature of each temperature sensor in the server, so that the subsequent adjustment of each fan in the server based on the heat dissipation condition of the server is facilitated, the server is always in the condition of stable internal temperature, and the normal operation of the server is ensured.

In an exemplary embodiment, as shown in FIG. 4, the specific process of step 104 includes steps 402 through 406. Wherein:

Step 402, it is determined whether the status data of the target fan indicates that the target fan is normal.

The state data comprises the rotating speed of the target fan and an in-place signal.

In implementation, the BMC determines whether the rotational speed of the target fan is below a preset rotational speed threshold. Meanwhile, the BMC judges whether the in-place signal of the target fan represents the in-place state of the target fan. If the speed of the target fan is lower than the speed threshold or the presence signal of the target fan indicates that the target fan is not present, the BMC determines that the state data indicates that the target fan is abnormal. If the rotating speed of the target fan is greater than or equal to the rotating speed threshold value and the in-place signal of the target fan indicates that the target fan is in place, the BMC determines that the state data indicates that the target fan is normal.

Step 404, if the status data indicates that the target fan is normal, determining whether the target temperature sensor corresponding to the target fan is an air inlet temperature sensor.

The air inlet temperature sensor is a temperature sensor for monitoring the air inlet of the server.

In implementation, if the state data indicates that the target fan is normal, the BMC determines whether the target temperature sensor corresponding to the target fan is a temperature sensor for monitoring an air inlet of the server.

In an alternative embodiment, if the target temperature sensor corresponding to the target fan is the air inlet temperature sensor, the BMC determines that all fans in the server are adjustment fans.

If the target temperature sensor is not the intake temperature sensor, step 406, the target fan is determined to be an adjustment fan.

In an implementation, if the target temperature sensor is not a temperature sensor monitoring the air intake of the server, the BMC determines the target fan to be an adjusting fan.

In this embodiment, the running condition of the target fan is determined according to the state data of the target fan, so that the relationship between the abnormal temperature inside the server and the target fan is clarified. Then, the fan is regulated according to the type of the target fan, so that the fan which needs to be regulated is obtained, the subsequent targeted regulation of the rotating speed of the regulated fan is facilitated, and the power consumption of the server is reduced.

In an exemplary embodiment, as shown in FIG. 5, the specific process of step 402 includes steps 502 through 506. Wherein:

Step 502, determining whether the rotation speed in the status data is lower than a preset rotation speed threshold, and determining whether the in-place signal in the status data represents that the target fan is in place.

Wherein the status data includes a rotational speed of the target fan and an on-line signal of the target fan. The in-place signal indicates whether the fan is operating properly.

In practice, the BMC is preset with a rotation speed threshold. The BMC judges whether the rotating speed is lower than a preset rotating speed threshold value. Meanwhile, the BMC judges whether the in-place signal represents that the target fan is in place or not.

Optionally, the rotation speed threshold is determined according to the characteristics of the fan and the heat dissipation requirement, and the embodiment of the application does not limit the rotation speed threshold.

If the rotational speed is below the rotational speed threshold and/or the presence signal indicates that the target fan is not present, a determination is made that the target fan is abnormal, step 504.

In an implementation, if the speed is below a speed threshold or the presence signal indicates that the target fan is not present, the BMC determines that the target fan is abnormal. If the speed is below the speed threshold and the presence signal indicates that the target fan is not in place, the BMC determines that the target fan is abnormal.

Step 506, if the rotational speed is greater than or equal to the rotational speed threshold and the in-place signal indicates that the target fan is in place, determining that the target fan is normal.

In an implementation, if the rotational speed is greater than or equal to the rotational speed threshold and the presence signal indicates that the target fan is in place, the BMC determines that the target fan is normal.

In one exemplary embodiment, where the status data characterizes a target fan anomaly, the fan needs to be adjusted based on the partition configuration data and the type of target fan. As shown in fig. 6, after the step 402 is performed, the specific processing procedure of the heat dissipation method further includes steps 602 to 606. Wherein:

Step 602, if the status data indicates that the target fan is abnormal, determining whether the type of the target fan is dual-rotor.

In an implementation, if the state data characterizes a target fan anomaly, the BMC determines that the server internal temperature anomaly is related to the target fan. Then, the BMC determines whether the type of the target fan is a dual rotor.

In step 604, if the type is dual-rotor, another fan of the dual-rotor fans where the target fan is located is determined as the adjustment fan.

In practice, if the type of the target fan is a dual rotor, the BMC determines another fan of the rotor fans in which the target fan is located as the tuning fan.

In step 606, if the type is not dual rotor, determining a target fan domain in which the target fan is located according to the partition configuration data, and determining other fans in the target fan domain as adjustment fans.

Wherein the partition configuration data comprises fan domains. The other fans are fans other than the target fan in the target fan domain.

In practice, if the type is not birotor, the BMC determines the target fan domain in which the target fan is located in each fan domain. The BMC then determines the other fans in the target fan domain as the adjustment fans.

In an exemplary embodiment, as shown in FIG. 7, the specific process of step 108 includes steps 702 through 704. Wherein:

Step 702, determining and adjusting a target rotating speed duty ratio corresponding to the fan according to the heat dissipation speed regulation parameter.

In implementation, the BMC is preset with a heat dissipation speed regulation parameter. And the BMC determines the target rotating speed duty ratio of the fan in the heat dissipation speed regulation parameters according to the abnormal condition.

Specifically, if the abnormal condition is that the target fan is normal and the target temperature sensor corresponding to the target fan is an air inlet temperature sensor, the BMC determines the rotating speed duty ratio of the disaster recovery fan in the air inlet temperature loss state in the heat dissipation speed regulation parameter. Then, the BMC determines the rotating speed duty ratio of the disaster recovery fan in the air inlet temperature loss state as the target rotating speed duty ratio of the adjusting fan. If the abnormal condition is that the target fan is normal and the target temperature sensor corresponding to the target fan is not the air inlet temperature sensor, the BMC determines the rotating speed duty ratio of the disaster recovery fan in the over-temperature state in the heat dissipation speed regulation parameter. Then, the BMC determines the rotating speed duty ratio of the disaster recovery fan in the over-temperature state as the target rotating speed duty ratio of the adjusting fan. If the abnormal condition is that the target fan is abnormal and the target fan is not a double-rotor fan, the BMC determines the rotating speed duty ratio of the disaster recovery fan in the abnormal state of the fan in the heat dissipation speed regulation parameters. The BMC determines the fan abnormal state disaster recovery fan rotating speed duty ratio as a target rotating speed duty ratio of the adjusting fan. If the abnormal condition is that the target fan is abnormal and the target fan is a double-rotor fan, the BMC determines the disaster recovery rotating speed duty ratio in the heat dissipation speed regulation parameter. The BMC determines the disaster recovery rotational speed duty ratio as a target rotational speed duty ratio for adjusting the fan.

Step 704, determining a target rotation speed according to the target rotation speed duty ratio, and adjusting the rotation speed of the adjusting fan to the target rotation speed to perform heat dissipation.

In an implementation, the BMC determines the target rotational speed of the fan to adjust based on the target rotational speed to air ratio. Then, the BMC adjusts and adjusts the rotation speed of the fan to the target rotation speed so as to radiate heat of the server.

In an exemplary embodiment, a method of dissipating heat is provided. Specifically, after the server is powered on, the BMC initializes various services and starts a heat dissipation speed regulation process. The normal heat dissipation speed regulation logic and the heat dissipation partition disaster recovery function under abnormal conditions are mainly realized by the heat dissipation speed regulation process. Specifically, the heat dissipation and speed regulation process loads disaster recovery partition configuration and heat dissipation and speed regulation parameters in the Json configuration file into the program structure body for use in subsequent logic. After loading the configuration parameters, executing the temperature abnormal partition disaster recovery logic and the fan abnormal partition disaster recovery logic by the heat dissipation speed regulation process. In the partitioned disaster recovery mode, because reasons and influences of each abnormal condition are different, different partitioned disaster recovery strategies are adopted in the heat dissipation speed regulation process, the fans are determined to participate in disaster recovery after calculation by combining disaster recovery logic, the lowest fan duty ratio required by disaster recovery is determined, and the fans which do not participate in disaster recovery continue to adopt normal speed regulation logic. In the normal speed regulation mode, the speed regulation duty cycle of each fan is calculated using the normal speed regulation parameters and the fan weight. And finally, obtaining the speed regulation duty ratio of each fan from the disaster recovery logic to drive the corresponding fan, and enabling the heat dissipation speed regulation process to enter the next speed regulation cycle. Fig. 8 is a flow chart of a heat dissipation speed regulation process, including:

Step 801, disaster recovery zone configuration data and heat dissipation parameters are read from the Json file to the structural body.

Step 803, executing the fan abnormal partition disaster recovery logic.

Step 804, driving the corresponding adjusting fans according to the target rotation speed duty ratio of each adjusting fan obtained by the temperature abnormal partition disaster recovery logic and the fan abnormal partition disaster recovery logic.

The specific execution flow of step 802 is shown in fig. 9, and includes:

Step 901, judging whether the temperature of the temperature sensor in the server exceeds a preset temperature threshold. If there is a temperature of the target temperature sensor exceeding the temperature threshold, step 902 is performed. If the temperature of the non-existence temperature sensor exceeds the temperature threshold value, the process is ended.

Step 902, determining whether the target temperature sensor is an air inlet temperature sensor. If the target temperature sensor is an intake air temperature sensor, step 907 is performed. If the target temperature sensor is not the intake air temperature sensor, step 903 is performed.

Step 903, a speed regulation algorithm of the target temperature sensor is obtained.

Step 904, determining a target fan corresponding to the target temperature sensor according to the speed regulation algorithm, and determining the target fan as the regulation fan.

Step 905, reading the rotating speed duty ratio of the disaster recovery fan in the over-temperature state.

Step 906, determining the rotating speed duty ratio of the disaster recovery fan in the over-temperature state as the target rotating speed duty ratio of the adjusting fan.

In step 907, all fans in the area of the air inlet temperature sensor are determined as adjustment fans.

Step 908, the rotation speed duty cycle of the disaster recovery fan in the air inlet temperature loss state is read.

Step 909, determining the rotation speed duty ratio of the disaster recovery fan in the air inlet temperature loss state as the target rotation speed duty ratio of the adjusting fan.

In addition, as shown in fig. 10, the specific execution flow of step 803 includes:

In step 1001, it is determined whether there is a target fan out of place or a target fan running at a low speed in the server. If there is no fan out of position and there is no fan running, the process is ended. If there is a target fan out of position or if there is a target fan running colloquially, then step 1002 is performed.

Step 1002, determine whether the target fan is a dual rotor fan. If the target fan is a dual rotor fan, step 1006 is performed. If the target fan is not a dual rotor fan, step 1003 is performed.

In step 1003, the target fan domain to which the target fan belongs is determined, and other fans in the target fan domain are determined as adjustment fans.

Step 1004, reading the rotation speed duty ratio of the disaster recovery fan in the abnormal state of the fan.

Step 1005, determining the fan abnormal state disaster recovery fan rotating speed duty ratio as the target rotating speed duty ratio of the adjusting fan.

In step 1006, the dual rotor fans to which the target fan belongs are determined, and the other fan of the dual rotor fans is determined as the adjustment fan.

Step 1007, determining a disaster recovery rotational speed duty cycle of the adjusting fan.

When the BMC finds that the heat dissipation of the server is abnormal, finer heat dissipation and disaster recovery can be performed according to the preset disaster recovery partition parameters, and the power consumption of the server is reduced on the premise of ensuring the disaster recovery effect. In addition, the heat dissipation method can be executed on the BMC, is independent of a specific hardware platform, and has good portability.

The server is divided into a main board bin and a GPU (Graphics Processing Unit, graphics processor) bin, the air channels of the two spaces are independent, and the fans are required to radiate heat from the two spaces simultaneously.
