Detailed ways

The following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of this application.

The core of the present application is to provide a server power adaptive communication method, equipment and medium.

In order to enable those skilled in the art to better understand the solution of the present application, the present application will be further described in detail below in conjunction with the drawings and specific implementation methods.

At present, the software communication interaction between the server power supply and the BMC is mainly based on the standard PMbus communication protocol, in which the address and data format of the power supply information register are clearly defined. However, as the application and reliability requirements become more and more complex, the addresses and information formats of the original PMbus registers are gradually changed and adjusted. For example, the addition of some customized information needs to add registers again, the format data length defined by the register information is not enough, and new functions need to add registers, or adjust the register address and data format. Any addition and adjustment of functions not defined by PMbus will require BMC to make corresponding adjustments. When the execution of some new functions requires more complex calculation and decision logic, BMC resources will be occupied and the overall communication and processing speed will be affected. Therefore, in order to solve the above problems, an embodiment of the present application provides a server power adaptive communication method. FIG. 1 is a flow chart of a server power adaptive communication method provided by an embodiment of the present application. The method is applied to a server including an adaptive communication device, and the adaptive communication device is connected to each power supply and BMC, and is used to switch the communication protocol of the power supply and transmit data to the BMC; wherein, the adaptive communication device includes multiple communication protocols; as shown in the figure 1, methods include:

S10: transmit the register information including the protocol value of the communication protocol to the power supply, so that the power supply selects the communication protocol according to the protocol value;

S11: receiving the data transmitted by the power supply according to the communication protocol;

S12: Transmit data to BMC.

Since any function additions and adjustments not defined by PMbus before require BMC to make corresponding adjustments, so in order not to occupy BMC resources in the case of executing complex calculation and decision logic, in this embodiment, the server adds adaptive communication device. FIG. 2 is a schematic diagram of connections between an adaptive communication device, a power supply, and a BMC provided by an embodiment of the present application. As shown in FIG. 2 , the adaptive communication device is set in the server, connected with each power supply and BMC, and used for switching the communication protocol of the power supply and transmitting data to the BMC. FIG. 3 is a schematic structural diagram of an adaptive communication device provided by an embodiment of the present application. As shown in Figure 3, the adaptive communication device can be realized by a digital signal processing (Digital Signal Processing, DSP) single-chip microcomputer or other similar specifications of the single-chip microcomputer, which is not limited in this embodiment; only keep the I2C communication line with the BMC, Realize basic information reading and polling; 3.3V power supply is provided through the server motherboard, and the software modules in the self-adaptive communication device are used to realize corresponding functions.

Specifically, in order to realize the communication protocol of switching the power supply and transmit data to the BMC, the server power supply adaptive communication method provided by the embodiment of the present application is applied to an adaptive communication device, specifically to a multi-protocol communication compatible module as a software module. The multi-protocol communication compatible module edits a variety of power supply communication protocols, and selects the communication protocol used by adding the protocol value of the communication protocol to the power supply. This function requires the power supply to add the protocol code of each design protocol. For example, the conventional communication protocol is PMbus1.2. If a new communication protocol is added, it is necessary to obtain the corresponding protocol name for the new protocol, and replace the register information of the original PMbus1.2 communication protocol with the protocol name synchronously. The multi-protocol communication compatible module will poll to confirm the communication protocol code of each power supply every time it is powered on, so as to confirm which protocol is used for analysis. Therefore, in this embodiment, by transmitting the register information including the protocol value of the communication protocol to the power supply, the power supply can select the communication protocol according to the protocol value; after the communication protocol used by the power supply is determined, the data transmitted by the power supply according to the communication protocol can be received , and transmit the data to the BMC, thereby realizing the communication between the power supply and the BMC.

It should be noted that when the communication protocol is selected for the power supply, the PMbus1.2 communication protocol is used for analysis by default; if the analysis fails, the power supply will try to use other existing protocols for analysis, so that data can be effectively realized for different communication protocols. Recognize and convert the data into a format that can be recognized by BMC uniformly to realize data transmission with BMC.

In this embodiment, the server power adaptive communication method is applied to a server including an adaptive communication device, and the adaptive communication device is connected to each power supply and BMC for switching the communication protocol of the power supply and transmitting data to the BMC. Wherein, the self-adaptive communication device includes multiple communication protocols. The method specifically includes: transmitting the register information including the protocol value of the communication protocol to the power supply for the power supply to select the communication protocol according to the protocol value; receiving the data transmitted by the power supply according to the communication protocol; and transmitting the data to the BMC. It can be seen that the above scheme improves the design method of direct communication between the power supply and BMC, and adds an adaptive communication device between the power supply and BMC to realize the secondary communication control between the power supply and BMC. The protocol value of the communication protocol is transmitted to the power supply, so that the power supply can obtain the communication protocol according to the protocol value, and transmit the data generated according to the communication protocol to the BMC through the adaptive communication device. It is no longer necessary to change the structure of the BMC, and it can realize the use of different communication protocols and adapt to complex control logic judgments, which improves the sense of experience.

As shown in Figure 3, as a preferred embodiment, the server further includes a signal processing device;

The signal processing device is connected to each power supply and the adaptive communication device, and is used to receive and process the signal output by the power supply, and transmit the processed signal to the adaptive communication device.

Since the adaptive communication device is used to switch the communication protocol of the power supply and transmit data to the BMC, in order to improve the quality of data signal transmission, it is also necessary to protect and process the signal. The signal processing device is mainly responsible for the processing of the protection signal output by the power supply and the communication signal. By connecting each power supply and the adaptive communication device, it is used to receive the signal output by the power supply and process the signal, and transmit the processed signal to the adaptive communication device. device. Signal processing mainly includes signal pull-up and pull-down, signal isolation, electrostatic discharge (Electro-Static discharge, ESD) protection and signal filtering processing. As shown in Figure 3, the present signal represents the power supply in-position signal; the alert signal is an alarm signal, which will be pulled down when the power supply is over-temperature and over-current; the pwok signal is an output indication signal, which is high by default and pulled down when the power supply output is abnormal ; The Vin_good signal is an indication signal of the power supply input voltage.

In this embodiment, the server also includes a signal processing device; the signal processing device is connected to each power supply and the adaptive communication device, and is used to receive the signal output by the power supply and process the signal, and transmit the processed signal to the adaptive communication device to realize The protection signal of the power output and the processing of the communication signal are realized.

During the operation of the server, some power supply protection signals need to be processed with fast interrupts, but the design of the BMC itself needs to consider the information polling and processing of all components except the power supply, which leads to fast protection signals of the power supply and complex control logic decisions Failure to respond in a timely manner reduces the effectiveness of the function. Therefore, in order to solve this problem, the server power adaptive communication method also includes:

Stop polling the power supply when an abnormal signal of the power supply is detected;

Read the status information of the power supply and set the BMC communication to stop responding or respond with buffer data.

As shown in FIG. 3, the above steps are implemented by the fast interruption protection processing module in the adaptive communication device. Specifically, the fast interrupt protection processing module mainly solves the situation that the original BMC polling cycle is long and cannot quickly process the power fast protection signal. When abnormal signals such as the Alert signal of the power supply are detected, the polling power supply function will be turned off, and the status word information of the power supply and the information data of the power supply that needs to be collected for different fault performances will be read at the first time, and the communication part with the BMC will be set as Either do not respond or reply with buffered data. In this way, the autonomous control communication function under the fault state is realized through the self-adaptive communication device.

In addition, some signal noise can also be filtered through the fast interrupt protection processing module, so as to adjust the fault response time.

In this embodiment, when an abnormal signal of the power supply is detected, the fast interrupt protection processing module of the self-adaptive communication device stops polling the power supply; reads the status information of the power supply and sets the BMC communication to stop responding or use buffer data to respond, realizing Autonomous control communication function under fault condition.

As a preferred embodiment, the server power adaptive communication method further includes:

Read the black box data of the power supply when an abnormal signal of the power supply is detected;

Call the fault information in the buffer of the power supply before the exception, so that the BMC can read and analyze it.

As shown in Fig. 3, the above steps are realized by the black box data storage module in the adaptive communication device. Specifically, the black box data storage module mainly stores and reads the black box data of the power supply after detecting that the output signal of the power supply is abnormal or the power is lost, and retrieves the fault information of the power supply information buffer before the problem occurs, so that BMC separate data reading and parsing.

In this embodiment, when an abnormal signal of the power supply is detected, the black box data storage module of the self-adaptive communication device reads the black box data of the power supply; the fault information in the buffer of the power supply before the abnormality is called, so that the BMC can read fetch and parse. The information collection and cache of the fault state are realized, and the traceability of fault information is increased.

As a preferred embodiment, the server power adaptive communication method further includes:

When the information of the power supply is obtained for the first time, if no change in power supply is detected, the data will be refreshed according to the preset cycle to reduce the polling rate;

When the real-time data is obtained, the polling rate is increased, and the real-time data is collected multiple times and averaged.

As shown in FIG. 3 , the above steps are implemented by the data cache processing module in the adaptive communication device. Specifically, the data cache and processing module mainly realizes the abnormal transmission of non-changing data information and the accuracy of real-time data. Taking the name of the power supply as an example, when the data cache processing module reads the name information of the power supply for the first time, if it does not recognize the change of the power supply or the change of the on-position information, it will not refresh the data information in real time, but only do the preset cycle Data refresh, reduce the number of polling, and reduce the polling rate while ensuring the validity of the information. In this embodiment, there is no limitation on the preset period, which depends on specific implementation conditions.

For real-time data, the data cache processing module will increase the polling rate and perform fast polling. Considering the long polling cycle of BMC, real-time data can be collected multiple times and averaged to ensure data stability.

In addition, when abnormal data failure occurs, the data in the data cache processing module will also be synchronously recorded to the black box data storage module, ensuring that multiple sets of data before the fault state can be recorded.

In this embodiment, when the information of the power source is obtained for the first time, if the data cache processing module in the adaptive communication device does not detect that the power supply has changed, it will refresh the data according to the preset cycle to reduce the polling rate and ensure the information The effectiveness; when the real-time data is obtained, the polling rate is increased, and the real-time data is collected multiple times and averaged to ensure the stability of the data.

As a preferred embodiment, the server power adaptive communication method further includes:

When the power supply needs to be upgraded, turn off the information reading and processing functions of the power supply;

Transfer the program burned by BMC to the power supply that needs to be upgraded.

As shown in FIG. 3 , the above steps are implemented by the update module in the self-adaptive communication device. Specifically, the upgrade update module mainly realizes the program burning and online upgrading functions of the software, and the program burning can be performed through the burning pin. After the first programming is completed, it supports the programming of each module in the adaptive communication device from the system side through the SDA and SCL communication pins of the BMC.

In addition, the upgrade and update module also includes the transfer function of PSU online upgrade and burning. When entering the online upgrade mode of the power supply, the adaptive communication device will turn off the conventional power supply information reading and processing functions, and only perform data transfer and transfer the program programmed by the BMC to the power module that needs to be upgraded.

In this embodiment, when the power supply needs to be upgraded, the upgrade update module in the self-adaptive communication device closes the information reading and processing functions of the power supply; the program programmed by the BMC is transmitted to the power supply that needs to be upgraded, thereby realizing the upgrade 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, the fault information is transmitted to the CPLD through the input and output interface.

It can be understood that, in the above-mentioned embodiments, the fast interrupt protection processing module can turn off the polling power supply function when the power supply fails, and read the status word information of the power supply and the information data of the power supply that needs to be collected for different fault performances at the first time. , and the communication part with the BMC will be set to not respond or use buffer data to respond. In order to further reduce the impact of power failure, when an abnormal signal of the power supply is detected, the failure information is transmitted to the CPLD (Complex Programmable Logic Device) through the input and output interface.

It can be understood that, as shown in FIG. 3 , the adaptive communication device reserves a functional I/O interface. 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. When an abnormal signal of the power supply is detected, the fault information is transmitted to the CPLD through the I/O interface, so that the CPLD can perform corresponding processing according to the fault situation.

In the above embodiments, the server power adaptive communication method is described in detail, and the present application also provides corresponding embodiments of the server and the server power adaptive communication device.
