[0003] Currently, server hardware monitors the system through control logic, and the entire process uses GPIO (General Purpose Input / Output) pins for monitoring. However, the following problems exist in actual operation:

[0004] 1) The board status information is monitored through BMC (Block Controller) and CPLD (Complex Programmable Logic Device). It can only perform logic control on power-on timing, power consumption and mode configuration, but the amount of information obtained by this method is relatively limited.

[0005] 2) The BMC and CPLD chips only perform the relevant logic control, but do not effectively record the monitoring signals. They cannot be converted into overall status information and transmitted to the BMC. The status of the steps where problems occur cannot be recorded, which makes it impossible for maintenance personnel to obtain information about the problems of the board.

[0006] 3) After the monitoring chip obtains the status signal, it does not analyze the overall status of the board in a timely manner, thus failing to output fault diagnosis information. Summary of the Invention

[0055] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0056] Example 1

[0057] A method for monitoring board status, such as Figure 1 and 2 As shown, it includes the following steps:

[0058] Step S1: Divide the register address ranges of general input / output according to the number of information categories of the board to be monitored, and each address range corresponds to an information management module.

[0059] In one specific embodiment, after dividing the register address range of general input / output according to the number of information categories of the board to be monitored, the method further includes:

[0060] Monitoring signals of the same category from the boards to be monitored are connected to the same address range; wherein the category of the monitoring signal corresponds to the category of the information management module.

[0061] The register address ranges for general-purpose input / output are divided according to the number of information categories of the boards to be monitored. The specific information categories of the boards to be monitored include board version information, power management, clock management, reset signal management, function configuration management, LED module, etc. Register address ranges are allocated sequentially according to the information categories of the boards to be monitored. For example, power management is allocated "[0x0000-0x01FF]". Then, monitoring signals of the same category of the boards to be monitored are connected to the same address range, so that each information management module manages one type of information.

[0062] like Figure 2 As shown, the CPLD is equipped with several information management modules, including the version information module of the board to be monitored, the power management module of the board to be monitored, the clock management module of the board to be monitored, the reset signal module of the board to be monitored, the function configuration module of the board to be monitored, and the LED module of the board to be monitored. The power management module of the board to be monitored is used to collect monitoring signals from “GPIO

[00] ~GPIO

[03] ”, where “GPIO

[00] ” corresponds to “PowerGood signal”, “GPIO

[01] ” corresponds to “EN signal”, “GPIO

[02] ” corresponds to “Fault signal”, and “GPIO

[03] ” corresponds to “Vsense signal”. These “PowerGood signal”, “EN signal”, “Fault signal” and “Vsense signal” come from the board to be monitored, board 1, board 2... board N, respectively. The reset signal module of the board to be monitored is used to collect the reset signals from “GPIO

[10] ~GPIO

[13] ”, and the corresponding reset signals are respectively from the board to be monitored 1, board 2... board N.

[0063] Furthermore, the BMC also monitors modules including the FRU module, Sensor module, and I2C Switch module. Specifically, the sensor module detects the temperature at the corresponding location using a temperature sensor.

[0064] Step S2: In response to the detection of the presence information of the board to be monitored, the information management module collects monitoring signals related to the information category from the general input / output and generates a status code.

[0065] In one specific embodiment, it includes:

[0066] Step S2.1: The information management module collects monitoring signals related to information categories from the general input and output;

[0067] Step S2.2: Record the timing data corresponding to the monitoring signal and convert the timing data into a state code.

[0068] Once the corresponding board insertion interface is identified, the information management module collects monitoring signals related to the information category from the GPIO. For example, one information management module might be the power management module of the board under monitoring. CPLD code is embedded in the CPLD to receive all power control signals, such as PG, EN, Vsense, and Fault signals. During board power-up, timing begins with the EN signal of each power supply, and a preset time interval is set. If the preset time interval is exceeded, a power-up fault is confirmed, and the corresponding timing data is recorded. Similarly, if the PG signal received by the power management module times out or is not output, the corresponding fault code for that power supply is recorded in the appropriate register. The reset signal management module, based on the PG signal collected by the power management module, outputs the chip's Reset signal according to the specifications, provided the power timing requirements are met. If the timing requirements are not met, a Reset exception is output and recorded in the corresponding register. The clock management module is responsible for controlling the CPLD's GPIO to output the OE signal after monitoring that all power supplies to the Clock Generate or the corresponding Clock Buffer are normal, thereby driving the Clock chip to output the clock signal.

[0069] In one specific embodiment, if the presence information of the board under test is not identified, the status information of the board will not be presented, thereby reducing the waste of resources.

[0070] Step S3: The complex programmable logic device transmits the status code to the baseboard management controller.

[0071] Each management module collects its own GPIO signal, records the corresponding timing data, and converts it into a status code, which is then sent to the BMC via I2C.

[0072] In one specific embodiment, after the complex programmable logic device transmits the status code to the baseboard management controller, it further includes:

[0073] The baseboard management controller parses the status code to obtain the real-time timing data;

[0074] The BMC code embeds monitoring logic into each management module, and extracts the real-time timing data through this monitoring logic to obtain the summarized real-time timing data of the boards to be monitored.

[0075] Step S4: The baseboard management controller compares the real-time timing data in the status code with the preset timing and outputs the status of the board to be tested.

[0076] In one specific embodiment, information about all the boards to be monitored, the general inputs and outputs corresponding to the boards to be monitored, and the preset timing data of the boards to be monitored are obtained;

[0077] The information of the board to be monitored, the general inputs and outputs, and the preset timing are combined into an information table.

[0078] The BMC code embeds monitoring logic into each management module. This monitoring logic summarizes the data from each management module and uses a list method to form an information table by combining each board under test with its corresponding GPIO and the preset timing requirements of the board under test.

[0079] In one specific embodiment, step S4 specifically includes:

[0080] Step S4.1: Obtain the preset time-series data from the information table;

[0081] Step S4.2: Compare the real-time timing data corresponding to the board to be monitored with the preset timing data;

[0082] Step S4.3: If the real-time timing data meets the preset timing requirements, the output board status is normal; if the real-time timing data does not meet the preset timing requirements, the output board status is abnormal.

[0083] The BMC integrates all monitoring signals from the board under test, as well as temperature data read by the temperature sensor, and then compares them with the preset timing requirements in the information table. If the real-time timing data meets the preset timing requirements, the overall status of the board under test is output as normal. If the real-time timing data does not meet the preset timing requirements, the board status is output as abnormal, and the BMC prints out the monitoring report information.

[0084] Furthermore, maintenance personnel can remotely access the BMC WEB to print fault diagnosis reports via the IPMI interface, thereby quickly obtaining information about problematic boards and improving board maintenance efficiency.

[0085] Specific implementation process: In this application, the register address ranges in the CPLD are divided according to the information categories of the boards to be monitored. Register address ranges are allocated sequentially according to power management, clock management, reset signal management, and function configuration management. Each management module collects its corresponding GPIO signals, records the corresponding timing data, and converts the timing data into status codes, which are then sent to the BMC via I2C. The BMC obtains the real-time timing data of the board under test and compares it with preset timing data. If the real-time timing data meets the preset timing requirements, the overall status of the board under test is output as normal; if the real-time timing data does not meet the preset timing requirements, the board status is output as abnormal, and a monitoring report is printed by the BMC. This enables accurate and rapid acquisition of information about problematic boards even when there are many boards under test, effectively improving the efficiency of locating the problem board and the cause of the fault.

[0086] Example 2

[0087] Corresponding to the above embodiments, this application provides a board status monitoring system, such as... Figure 3 As shown, the system includes:

[0088] The allocation module is used to divide the register address range of general input and output according to the number of information categories of the board to be monitored, and each address range corresponds to an information management module;

[0089] The acquisition module is used to respond to the identification of the presence information of the board to be monitored. The information management module acquires monitoring signals related to the information category from the general input and output and generates a status code.
