Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. 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 invention.
Referring to fig. 1, fig. 1 is a flowchart of a method for adapting a heat dissipation policy of a BMC according to an embodiment of the present invention. The method can comprise the following steps:
step 101: acquiring a heat dissipation strategy control parameter corresponding to each component in a heat dissipation strategy file; wherein each heat dissipation strategy control parameter comprises component information and a heat dissipation parameter.
It is understood that the heat dissipation policy file in this step may be a file storing the heat dissipation policy control parameter corresponding to each component, such as a BMC _ thermal. Each of the heat dissipation strategy control parameters in this step may include information (i.e., component information) of a respective corresponding component and a heat dissipation parameter for forming a heat dissipation strategy with a corresponding preset calculation strategy. The heat dissipation parameter in this step may be a parameter that can be adjusted correspondingly according to a component change and a server model change in the heat dissipation policy, such as a P parameter, an I parameter, a D parameter, a temperature difference parameter, an integral parameter, a regulated temperature point parameter, and the like in a heat dissipation policy regulated and controlled in a current general PID manner (i.e., a PID control heat dissipation policy), where the heat dissipation parameter may include the P parameter, the I parameter, the D parameter, the temperature difference parameter, the integral parameter, and the regulated temperature point parameter, and may form a PID control heat dissipation policy with a preset calculation policy regulated and controlled in the PID manner (i.e., a PID control calculation policy).
Specifically, the specific content of the heat dissipation strategy file in the embodiment can be set by a designer according to a practical scene and user requirements, for example, the BMC adopts a unified calculation strategy (such as a PID control calculation strategy), determines the heat dissipation strategy corresponding to each component, i.e. the number of the preset calculation strategies is 1, the heat dissipation strategy file may include the heat dissipation strategy control parameters corresponding to each component, for example, when the heat dissipation policy file may be a standard formatted file (such as a BMC _ thermal. bin file), each row of the heat dissipation policy file includes a heat dissipation policy control parameter of a component, and a heat dissipation parameter in the heat dissipation policy control parameters may include a P parameter, an I parameter, a D parameter, a temperature difference parameter, an integral parameter, and a regulation temperature point parameter, a format (i.e., a structure) of each row of the heat dissipation policy file may be as follows:
typedefstruct
{
INT8U SensorNumber; // corresponding part number
float Kp; // policy parameter P
float Ki; // policy parameter I
float Kd; // policy parameter D
int Le; // temperature difference
int Integral; // integral
intSetpoint; v/control of temperature Point
}FAN_CONTROL_T；
The specific parameter values of the P parameter, the I parameter, the D parameter, the temperature difference parameter, the integral parameter, and the temperature point parameter in the above format may be set by a user (e.g., a heat dissipation engineer).
Correspondingly, when the number of the preset calculation strategies is multiple, the heat dissipation strategy file may further include parameters, namely heat dissipation strategy selection parameters, corresponding to each component, for selecting the required preset calculation strategy; therefore, the BMC can select parameters according to the heat dissipation strategy corresponding to each component, and determine the preset calculation strategy which is correspondingly needed to be used by the heat dissipation strategy forming each component. This embodiment does not set any limit to this.
Similarly, the specific file type of the heat dissipation policy file in this embodiment may be set by a designer, for example, the heat dissipation policy file may be a BMC _ thermal.
It should be noted that, for the specific manner in which the BMC obtains the heat dissipation policy control parameter corresponding to each component in the heat dissipation policy file in this step, the specific manner may be set by a designer according to a use scenario and a user requirement, for example, when the BMC firmware is compiled, the heat dissipation policy file may be compiled into the BMC firmware, and after the BMC of the server runs, the heat dissipation policy file may be written into an EEPROM (a storage chip whose data is not lost after power failure), so that the BMC may read the heat dissipation policy control parameter corresponding to each component from the EEPROM. As long as the BMC can read and load the heat dissipation policy control parameter corresponding to each component from the heat dissipation policy file, this embodiment does not set any limitation to this.
Step 102: and determining the heat dissipation strategy corresponding to each component by using the preset calculation strategy corresponding to each component according to the heat dissipation strategy control parameters.
It can be understood that the purpose of this step may be to determine, by the BMC, the respective heat dissipation policy of each component by using the preset calculation policy corresponding to each component and the heat dissipation parameter in the heat dissipation policy control parameter, so that the heat dissipation control of the component can be completed by using the respective heat dissipation policy of each component.
The component for determining the heat dissipation policy in this step may be a component corresponding to component information in each heat dissipation policy control parameter, such as a CPU, a PSU, a GPU, a network card, and the like in the server. The preset calculation strategy in this step may be a preset calculation strategy for forming a corresponding heat dissipation strategy with the corresponding heat dissipation parameters; the specific number and storage manner of the preset calculation strategies are not limited in this embodiment, for example, when the number of the preset calculation strategies may be 1, the preset calculation strategy may be a calculation strategy (i.e., a PID control calculation strategy) that is formed by editing BMC codes and is regulated and controlled in a current general PID manner, so that the heat dissipation parameters corresponding to each component and the uniform PID control calculation strategy form the heat dissipation strategies corresponding to each component.
Specifically, for the specific manner of determining the respective heat dissipation strategy of each component by using the preset calculation strategy corresponding to each component according to the heat dissipation strategy control parameters in this step, the specific manner can be set by a designer according to a practical scene and a user requirement, and if the number of the preset calculation strategies is 1, the BMC can determine the respective heat dissipation strategy of each component according to the preset calculation strategy and the respective heat dissipation strategy control parameters corresponding to each component, that is, determine the heat dissipation strategy of the component corresponding to the component information in each heat dissipation strategy control parameter. When the number of the preset calculation strategies is multiple (namely, greater than 1), the BMC may first determine the preset calculation strategy corresponding to each component according to the heat dissipation strategy selection parameter corresponding to each component in the heat dissipation strategy file; determining a heat dissipation strategy corresponding to each component according to a preset calculation strategy corresponding to each component and a heat dissipation strategy control parameter corresponding to each component; that is, the BMC may first determine a preset calculation policy corresponding to each component according to a heat dissipation policy selection parameter corresponding to each component information in each heat dissipation policy control parameter in the heat dissipation policy file; and determining the heat dissipation strategy corresponding to each component by using the heat dissipation parameters in the preset calculation strategy and the heat dissipation strategy control parameters corresponding to each component. This embodiment does not set any limit to this.
Step 103: and performing heat dissipation control on each component by using the heat dissipation strategy corresponding to each component.
It can be understood that the purpose of this step may be to implement, for the BMC, heat dissipation control of each component by using the determined heat dissipation policy corresponding to each component.
Specifically, the present embodiment does not limit the specific manner in which the BMC performs heat dissipation control on each component by using the respective heat dissipation policy corresponding to each component, for example, the specific manner may be implemented in the same or similar manner as the heat dissipation policy execution method in the prior art.
Further, in order to facilitate the adjustment of the user on the heat dissipation policy of the component, the embodiment may further include a step of the BMC correspondingly adjusting the content in the heat dissipation policy file according to the obtained file adjustment command, so that the user may directly adjust the content in the heat dissipation policy file during the start operation of the BMC.
Specifically, the specific type and the obtaining mode of the file adjusting command can be set by a designer, and the file adjusting command can be a command (i.e., a file adjusting IPMI command) of an Intelligent Platform Management Interface (IPMI) protocol, so that the IPMI protocol inside and outside the band can modify and replace the heat dissipation policy file, thereby further realizing the rapid adaptation of the heat dissipation policy; that is, the BMC in the server may receive the file adjustment IPMI command transmitted by the server, or may receive the file adjustment IPMI command transmitted by a device external to the server. That is, the embodiment may further include obtaining a file adjustment IPMI command; and adjusting the IPMI command according to the file, and correspondingly adjusting the content in the heat dissipation strategy file.
In this embodiment, according to the heat dissipation strategy control parameters in the heat dissipation strategy file, the preset calculation strategy corresponding to each component is utilized to determine the heat dissipation strategy corresponding to each component, so that the adjustment of the content and the number of the heat dissipation strategies can be realized by adjusting the heat dissipation strategy file without modifying a BMC code, the quick adaptation of the heat dissipation strategies is realized, the workload of BMC research and development and the heat dissipation test is reduced, and the user experience is improved.
