Detailed Description
The following description of the technical solutions in the embodiments of the present application will be made clearly and completely with reference to the drawings in the embodiments of the present application, and it is apparent that the described embodiments are only some embodiments of the present application, but not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments herein without making any inventive effort are intended to fall within the scope of the present application.
The core of the application is to provide a server power supply self-adaptive communication method, equipment and medium.
In order to provide a better understanding of the present application, those skilled in the art will now make further details of the present application with reference to the drawings and detailed description.
Currently, software communication interaction between a server power supply and a BMC is mainly based on a standard PMbus communication protocol, and addresses and data formats of power supply information registers in the protocol are well defined. However, as application and reliability requirements become more complex, the address and information formats of the original PMbus registers gradually change and adjust. For example, the addition of some customization information requires re-adding registers, the format data length defined by the register information is insufficient, and the new adding function and the like all require adding registers or adjusting register addresses and data formats. The BMC is required to make corresponding adjustment when any function increment and adjustment which is not defined by the PMbus occurs, and under the condition that more complex calculation judgment logic is required for executing some new functions, resources of the BMC are occupied to influence the overall communication and processing speed. Therefore, in order to solve the above-mentioned problems, the embodiments of the present application provide a server power supply adaptive communication method. Fig. 1 is a flowchart of a server power adaptive communication method according to an embodiment of the present application. The method is applied to a server comprising an adaptive communication device, wherein the adaptive communication device is connected with each power supply and the BMC, and is used for switching the communication protocol of the power supply and transmitting data to the BMC; wherein the self-adaptive communication device comprises a plurality of communication protocols; as shown in fig. 1, the method includes:
s10: transmitting register information containing protocol values of the communication protocol to the power supply for the power supply to select the communication protocol according to the protocol values;
s11: receiving data transmitted by a power supply according to a communication protocol;
s12: data is transferred to the BMC.
Since any function increase and adjustment not defined by PMbus occurs before, the BMC is required to make a corresponding adjustment, so in order to not occupy the resources of the BMC under the condition of executing the calculation decision logic which needs to be more complex, in this embodiment, the server is newly added with an adaptive communication device. Fig. 2 is a schematic diagram of connection between the adaptive communication device and a power supply and a BMC according to an embodiment of the present application. As shown in fig. 2, the adaptive communication device is disposed in the server, connected to each power supply and the BMC, and configured to switch a communication protocol of the power supply and transmit data to the BMC. Fig. 3 is a schematic structural diagram of an adaptive communication device according to an embodiment of the present application. As shown in fig. 3, the adaptive communication device may be implemented by a digital signal processing (Digital Signal Processing, DSP) single-chip microcomputer or other single-chip microcomputer with similar specifications, which is not limited in this embodiment; only an I2C communication line is reserved between the BMC and the BMC, so that basic information reading and polling are realized; and 3.3V power supply is performed through the server main board, and a software module in the self-adaptive communication device is used for realizing corresponding functions.
Specifically, in order to realize switching of a communication protocol of a power supply and transmitting data to a BMC, the server power supply adaptive communication method provided in the embodiment of the present application is applied to an adaptive communication device, and is specifically applied to a multi-protocol communication compatible module serving as a software module. The multi-protocol communication compatible module edits various power supply communication protocols, and the function requires the power supply to add protocol codes of each design protocol by selecting the used communication protocol from the protocol values of the power supply added communication protocol. For example, if a communication protocol is newly added, the corresponding protocol name is needed to be taken for the newly added protocol, and the register information of the original pmbuss 1.2 communication protocol is synchronously replaced by the protocol name. And the multi-protocol communication compatible module polls and confirms the communication protocol codes of all power supplies when the power is on each time, so that the analysis is confirmed according to what protocol. Therefore, in this embodiment, the power supply can select the communication protocol according to the protocol value by transmitting the register information including the protocol value of the communication protocol to the power supply; after the communication protocol used by the power supply is determined, the data transmitted by the power supply according to the communication protocol is received and transmitted to the BMC, so that the communication between the power supply and the BMC is realized.
It should be noted that when the power supply selects the communication protocol, pmbus1.2 is used as default for analysis; if analysis fails, the power supply can try to analyze by using other existing protocols, so that effective identification of data can be realized for different communication protocols, the data is converted into a format which can be uniformly identified by the BMC, and data transmission with the BMC is realized.
In this embodiment, the server power supply adaptive communication method is applied to a server including an adaptive communication device, where the adaptive communication device is connected to each power supply and the BMC, and is used to switch a communication protocol of the power supply and transmit data to the BMC. The adaptive communication device comprises a plurality of communication protocols. The method comprises the following steps: transmitting register information containing protocol values of the communication protocol to the power supply for the power supply to select the communication protocol according to the protocol values; receiving data transmitted by a power supply according to a communication protocol; data is transferred to the BMC. Therefore, according to the scheme, the self-adaptive communication device is added between the power supply and the BMC through improving the design mode of direct communication between the power supply and the BMC, the two-stage communication control between the power supply and the BMC is realized, the protocol value of the communication protocol in the self-adaptive communication device is transmitted to the power supply, so that the power supply can acquire the communication protocol according to the protocol value, and data generated according to the communication protocol is transmitted to the BMC through the self-adaptive communication device. The BMC structure does not need to be changed any more, different communication protocols can be used, complex control logic judgment is adapted, and experience is improved.
As shown in fig. 3, as a preferred embodiment, the server further comprises signal processing means;
the signal processing device is connected with each power supply and the self-adaptive communication device and is used for receiving signals output by the power supplies, processing the signals and transmitting the processed signals to the self-adaptive communication device.
Because the adaptive communication device is used for switching the communication protocol of the power supply and transmitting data to the BMC, in order to improve the transmission quality of the data signal, the signal needs to be protected and processed. The signal processing device is mainly responsible for processing protection signals and communication signals output by the power supply, and is used for receiving signals output by the power supply and processing the signals through connecting the power supply and the self-adaptive communication device, and transmitting the processed signals to the self-adaptive communication device. The signal processing mainly comprises signal pull-up and pull-down, signal isolation, electrostatic discharge (ESD) protection and signal filtering processing. As shown in fig. 3, the present signal represents a power supply on-bit signal; the alert signal is an alarm signal, and can be pulled down when the power supply is over-temperature and over-current; the pwok signal is an output indication signal, defaults to high, and is pulled down when the power supply output is abnormal; the vin_good signal is a power supply input voltage indication signal.
In this embodiment, the server further includes a signal processing device; the signal processing device is connected with each power supply and the self-adaptive communication device and is used for receiving and processing signals output by the power supply and transmitting the processed signals to the self-adaptive communication device, so that the processing of protection signals and communication signals output by the power supply is realized.
During the running process of the server, some power protection signals need to be rapidly interrupted, but the BMC itself needs to be designed to consider information polling and processing of all components except the power supply, which results in that the rapid protection signals of the power supply and complex control logic judgment cannot be responded in time, so that the effectiveness of functions is reduced. Thus, to solve this problem, the server power adaptive communication method further includes:
stopping polling the power supply when an abnormal signal of the power supply is detected;
and reading the state information of the power supply and setting BMC communication stop response or buffer data response.
As shown in fig. 3, the above steps are implemented by a fast interrupt protection processing module in the adaptive communication device. Specifically, the quick interrupt protection processing module mainly solves the problem that the original BMC polling period is long and cannot process the power supply quick protection signal quickly. When detecting abnormal signals such as an Alert signal of a power supply, the power supply polling function is turned off, state word information of the power supply and information data of the power supply, which need to be collected for different fault manifestations, are read at the first time, and a communication part with the BMC is set to be unresponsive or responds by using buffer data. Thus, the self-adaptive communication device realizes the function of autonomous control communication under the fault state.
In addition, the filtering processing can be performed on some signal noise through the rapid interrupt protection processing module, so that the time of fault response is adjusted.
In this embodiment, when an abnormal signal of the power supply is detected, the fast interrupt protection processing module of the adaptive communication device stops polling the power supply; and reading the state information of the power supply and setting BMC communication stop response or buffer data response, thereby realizing the autonomous control communication function under the fault state.
As a preferred embodiment, the server power adaptive communication method further includes:
reading black box data of the power supply when an abnormal signal of the power supply is detected;
and calling fault information in a buffer area of the power supply before abnormality so as to facilitate the BMC to read and analyze.
As shown in fig. 3, the above steps are implemented by a black box data storage module in the adaptive communication device. Specifically, the black box data storage module is mainly used for storing and reading black box data of a power supply after detecting that an abnormal or power failure occurs in a signal output by the power supply, and calling fault information of a power supply information buffer area before a problem occurs, so that independent data reading and analysis of the BMC are facilitated.
In this embodiment, when an abnormal signal of the power supply is detected, the black box data storage module of the adaptive communication device reads the black box data of the power supply; and calling fault information in a buffer area of the power supply before abnormality so as to facilitate the BMC to read and analyze. The information collection and the cache of the fault state are realized, and the traceability of the fault information is improved.
As a preferred embodiment, the server power adaptive communication method further includes:
when the information of the power supply is acquired for the first time, if the change of the power supply is not detected, data refreshing is carried out according to a preset period so as to reduce the polling rate;
when the real-time data is acquired, the polling rate is increased, and the real-time data is acquired for a plurality of times and averaged.
As shown in fig. 3, the above steps are implemented by a data buffer processing module in the adaptive communication device. Specifically, the data caching and processing module mainly realizes abnormal transmission of non-change data information and accuracy of real-time data. Taking the name of the power supply as an example, after the data cache processing module reads the name information of the power supply for the first time, if the power supply change or the bit information change is not recognized, the data information cannot be refreshed in real time, only the data refresh of a preset period is performed, the polling frequency is reduced, the polling rate is reduced, and meanwhile, the effectiveness of the information is ensured. In this embodiment, the preset period is not limited, and depends on the specific implementation.
And aiming at real-time data, the data caching and processing module can improve the polling rate and perform quick polling. Considering that the polling period of the BMC is longer, the method of collecting and averaging the real-time data for multiple times can be adopted, so that the stability of the data is ensured.
In addition, when abnormal failure of data occurs, the data in the data cache processing module can be synchronously recorded to the black box data storage module, so that multiple groups of data before a fault state can be recorded.
In this embodiment, when the information of the power supply is acquired for the first time, if the data cache processing module in the adaptive communication device does not detect that the power supply of the power supply changes, the data cache processing module performs data refreshing according to a preset period, so as to reduce the polling rate and ensure the validity of the information; when the real-time data is acquired, the polling rate is increased, the real-time data is acquired for multiple times and the average value is taken, so that the stability of the data is ensured.
As a preferred embodiment, the server power adaptive communication method further includes:
when the power supply needs to be upgraded, the information reading and processing functions of the power supply are turned off;
and transmitting the program burnt by the BMC to a power supply to be upgraded.
As shown in fig. 3, the above steps are implemented by an upgrade update module in the adaptive communication device. Specifically, the upgrade update module mainly realizes the program burning and online upgrade functions of the software, and the program burning can be performed through a burning pin. And after the first burning is finished, the burning of each module in the self-adaptive communication device is carried out from the system end through SDA and SCL communication pins of the BMC.
In addition, the upgrade update module also comprises a switching function of PSU online upgrade burning. When the on-line upgrading mode of the power supply is entered, the self-adaptive communication device can close the conventional power supply information reading and processing functions, only data transfer transmission is performed, and a program burnt by the BMC is directly jumped to a power supply module to be upgraded.
In this embodiment, when the power supply needs to be upgraded, an upgrade update module in the adaptive communication device turns off the information reading and processing functions of the power supply; and transmitting the program burnt by the BMC to a power supply to be upgraded, thereby realizing the upgrading of the power supply.
As a preferred embodiment, the server power adaptive communication method further includes:
when an abnormal signal of the power supply is detected, fault information is transmitted to the CPLD through the input/output interface.
It can be understood that in the above embodiment, the fast interrupt protection processing module can turn off the power supply polling function when the power supply fails, read the status word information of the power supply and the information data of the power supply that need to be collected for different fault manifestations at the first time, and set the communication part with the BMC to be non-responsive or respond by using the cache data. In order to further reduce the influence of the power failure, when an abnormal signal of the power is detected, failure information is transmitted to CPLD (Complex Programmable Logic Device) through the input-output interface.
It will be appreciated that the adaptive communication device reserves a functional I/O interface as shown in fig. 3. The corresponding I/O can be set according to the fault condition to feed back the fault condition to the CPLD or other components so that the CPLD or other components can perform corresponding processing according to the fault condition.
In this embodiment, the adaptive communication device reserves a functional I/O interface, and when an abnormal signal of the power supply is detected, fault information is transmitted to the CPLD through the I/O interface, so that the CPLD performs corresponding processing according to the fault condition.
In the above embodiments, the server power adaptive communication method is described in detail, and the present application further provides corresponding embodiments of the server and the server power adaptive communication device.
