Summary of the Invention

[0025] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Modern computer systems are becoming increasingly complex, and various application scenarios require a large number of backend servers for support, placing higher demands on server stability. Memory failures are a key factor affecting server stability. Accurately diagnosing memory failures, recording memory alarm information, and reducing the probability of memory-triggered crashes have become core technical challenges in the industry and a focus of customer attention. Related technologies primarily focus on fault diagnosis and repair after system crashes, but they cannot provide early detection and warnings for potential memory failures, thus failing to guarantee server system stability.

[0027] To address the aforementioned issues, the purpose of this specification is to propose a server memory fault detection method, system, and electronic device. By utilizing a Baseboard Management Controller (BMC) to monitor system interrupt signals of the server system, determine the relevant attribute information of the memory unit corresponding to the system terminal signal, and perform fault diagnosis and detection based on the relevant attribute information, memory faults can be detected in advance to provide early warning, avoid server downtime, and ensure the stability of server system operation.

[0028] To achieve the above objectives, one aspect of this specification provides a method for detecting server memory faults.

[0029] like Figure 1 As shown, this specification provides a server memory fault detection method according to one or more optional embodiments, applied to a baseboard controller (BMC). The method includes:

[0030] S1: Monitor the target server. When the target server triggers a system interrupt signal, collect basic error information of the memory unit corresponding to the system interrupt signal.

[0031] During server operation, an interrupt signal is triggered when an abnormal situation occurs in the server memory. Various system signals of the target server can be monitored during its operation to intercept system interrupt signals triggered during system operation, thereby identifying memory units where abnormal situations may exist based on these interrupt signals.

[0032] In some alternative implementations, the following methods can be used to monitor the target server:

[0033] The baseboard controller (BMC) is communicatively connected to the basic input / output system (BIOS) in the target server. The BIOS system receives various system signals related to the target server and performs real-time monitoring and identification of these system signals.

[0034] The system signals are identified to determine if a system interrupt signal is present. When an abnormality occurs in the server memory, a system interrupt signal, namely the System Management Interrupt (SMI) signal, will be triggered during the operation of the target server system.

[0035] When the system interrupt signal SMI exists in the target server, the SMI signal is extracted for further analysis.

[0036] By parsing the system interrupt signal, basic error information of the corresponding memory unit can be obtained. In some optional embodiments, the following methods can be used to collect the basic error information of the memory unit corresponding to the system interrupt signal:

[0037] The interrupt handler function that triggers the system interrupt signal SMI in the target server system is identified. Reverse engineering the SMI based on this interrupt handler function allows us to determine the source of the system interrupt, namely the memory cell where an anomaly may exist. Simultaneously, the coordinates and system physical address of the memory cell can also be determined.

[0038] The basic error information includes the system interrupt signal and the coordinate information and system physical address of the corresponding memory unit.

[0039] S2: Analyze the basic error information to determine the corresponding memory unit attribute information, and store the memory unit attribute information in the internal database.

[0040] For memory units that may have abnormal conditions, further analysis can be performed based on their corresponding basic error information to determine more comprehensive related attribute information.

[0041] like Figure 2 As shown, in one or more optional embodiments of this specification, a server memory fault detection method is provided, in which the basic error information is parsed to determine the corresponding memory unit attribute information, including:

[0042] S201: Based on the coordinate information and the corresponding local hardware configuration information of the target server, query and determine the memory module to which the memory unit belongs in the target server and the positioning row and column information in the memory module.

[0043] The local hardware configuration information of the target server is obtained. This local hardware configuration information records the specific hardware attribute information of the memory device modules in the server. The hardware attribute information may include the number of memory modules configured in the memory device module, the corresponding firmware parameters, the manufacturer, the corresponding installation location, the storage unit row and column information of the memory sticks in each memory module, silkscreen information, etc.

[0044] The local hardware configuration information can be stored on the server in the form of an asset information list, and the local hardware configuration information can be obtained through query commands.

[0045] Based on the local hardware configuration information, the memory module to which the memory unit belongs in the target server can be determined according to the coordinate information, as well as the specific row and column information within the memory module. This coordinate information helps staff accurately locate specific memory units.

[0046] S202: Translate the physical address of the system to generate the corresponding logical memory address of the memory unit in the target server.

[0047] During server system operation, data transmission, read / write operations utilize the system logical addresses of various memory units. These system physical addresses can be translated into corresponding memory logical addresses based on the server system architecture information. These memory logical addresses facilitate the system's execution of instructions to the appropriate memory units.

[0048] The memory unit attribute information includes the memory module corresponding to the memory unit, the positioning row and column information in the memory module, and the corresponding memory logical address.

[0049] After determining the memory attribute information corresponding to the memory unit, the memory attribute information can be stored in a dedicated internal database. The internal database is used to maintain memory unit information for the entire server system and can include multiple data items, each recording relevant information for one memory unit.

[0050] In some optional implementations, the memory unit attribute information can be stored in an internal database by: formatting the memory unit attribute information to form a uniformly formatted command message, and sending the command message to the internal database to generate corresponding data items. The command message can be an IPMI command message.

[0051] like Figure 3 As shown, in a server memory fault detection method provided by one or more optional embodiments of this specification, the data items include memory cell coordinates, error flags, error counts, physical memory addresses, and logical memory addresses.

[0052] The memory cell coordinates are used to record the row and column information of the corresponding memory cell, and the row and column information is used to indicate the specific physical location of the memory cell.

[0053] The error flag is used to indicate whether a memory error has occurred in the corresponding memory unit, causing a system interrupt signal to be triggered. Figure 3The “CE (Correctable Error) flag” indicates the error flag item.

[0054] The error count item represents the number of times that the corresponding memory unit triggers a memory error, resulting in the triggering of a system terminal signal. Figure 3 The "CE (Correctable Error) Quantity" in the text refers to the number of errors mentioned above.

[0055] The physical memory address is used to represent the actual physical address information of the corresponding memory unit in the target server.

[0056] The memory logical address is used to represent the specific logical address information of the corresponding memory unit in the target server system.

[0057] The data items in the internal database can record detailed information about the corresponding memory units.

[0058] like Figure 4 As shown, in one or more optional embodiments of this specification, a server memory fault detection method further includes, when sending the command message to the internal database:

[0059] S401: Determine whether an associated data item corresponding to the command message already exists in the internal database. The associated data item refers to the data item that corresponds to the same memory unit as the command message.

[0060] S402: In response to the existence of the associated data item in the memory database, update the associated data item according to the command message.

[0061] Updating the associated data item mainly involves updating the specific value of the Error Count (CE) item within that associated data item. Taking memory unit A as an example, during server operation, when memory unit A triggers a system interrupt signal for the first time, the fault detection method writes a data item corresponding to memory unit A into the internal database, where the CE count is recorded as 1. When memory unit A triggers a system interrupt signal again, the associated data item already exists in the internal database, and the CE count in the associated data item is updated to 2.

[0062] S403: In response to the absence of the associated data item in the memory database, a new data item is generated based on the data content in the command message.

[0063] If the associated data item does not exist in the memory database, it means that the corresponding memory is likely to trigger a system interrupt signal for the first time within a preset time period. In this case, a new data item is generated in the internal database, which records various information of the corresponding memory unit.

[0064] S3: Query and detect the data content in the internal data to determine the information frequency of the memory unit attribute information corresponding to multiple memory units within a preset time period.

[0065] The frequency of the memory unit attribute information generated corresponding to the memory unit within a preset time period can be determined based on the number of CEs recorded in the data items of the internal database. This information frequency characterizes the number of times the memory unit triggers a system interrupt signal within the preset time period, that is, the number of times the memory unit may experience abnormal conditions within the corresponding time period. It is understood that the number of times a memory unit may experience abnormal conditions can, to some extent, characterize the risk of a memory failure leading to server system downtime; a higher number indicates a higher risk of failure.

[0066] Based on the above analysis, in some optional embodiments, the following method can be used to determine whether the corresponding memory unit has a memory fault: compare the information frequency with a preset error frequency threshold; in response to the information frequency exceeding the preset error frequency threshold, determine that the corresponding memory unit has a memory fault.

[0067] The frequency of information, i.e., the number of times an anomaly occurs in a corresponding memory unit, can be used to measure and characterize the risk of memory failure. Comparing it to a preset error threshold, exceeding the threshold confirms a memory failure in the memory unit, which could potentially cause server system crashes. The preset error threshold can be flexibly set and adjusted according to actual conditions; generally, it can be set to 2 or 3. That is, if a memory unit experiences two or more anomalies within a preset time period, it can be determined that the memory unit is faulty and poses a significant risk. The preset time period can also be set and adjusted according to actual conditions; for example, it can be set to 24 hours or 12 hours.

[0068] S4: Based on the frequency of the information, determine whether the corresponding memory unit has a memory fault. When it is determined that the memory unit has a memory fault, generate corresponding alarm information according to the memory unit attribute information and report it.

[0069] When a memory fault is detected in the memory unit, an alarm should be issued in a timely manner. An alarm message should be generated based on the corresponding memory unit attribute information and reported to the relevant personnel so that they can take appropriate action and eliminate the memory fault.

[0070] In some alternative implementations, the following methods can be used to generate warning information:

[0071] Based on the memory cell attribute information, the memory module corresponding to the faulty memory cell and the location row and column information of the memory cell within that memory module are determined. When a fault is determined in a memory cell, relevant memory coordinate information can also be extracted from the data item corresponding to the memory cell in the internal database. This includes the memory module to which the memory cell belongs and its location row and column information within the corresponding memory module. The alarm information includes the memory module, the corresponding location row and column information, a memory fault alarm prompt, and the corresponding prompt time information.

[0072] The memory module and corresponding row and column positioning information in the warning information help staff quickly locate the actual physical location of the faulty memory unit, perform fault recovery processing, or replace the faulty memory unit or memory module, thereby ensuring the safe operation of the server system, avoiding server system downtime due to memory failure, and improving the stability of server system operation.

[0073] The described server memory fault detection method utilizes BMC to monitor system interrupt signals of the server system, analyzes the system interrupt signals to determine the memory cell information corresponding to the memory unit, and diagnoses whether a memory fault exists based on the frequency of the memory cell attribute information. This method can efficiently and quickly accurately determine memory cell faults and promptly generate alarm information for notification when a memory cell fault is determined, so that staff can carry out recovery processing. It can detect memory faults in advance and provide early warning, effectively avoiding server downtime and ensuring the stability of server system operation.

[0074] like Figure 5 As shown, one or more optional embodiments of this specification provide a server memory fault detection method, which, after determining that a memory unit has a memory fault, further includes:

[0075] S501: Determine the physical and logical memory addresses of the memory cells where memory faults exist.

[0076] The physical memory address and the logical memory address can be determined based on the corresponding memory unit attribute information, or they can be extracted from the data item corresponding to the memory unit in the internal database.

[0077] S502: Based on the physical memory address and the logical memory address, perform a memory isolation operation on the memory unit so that the target server ignores the memory unit.

[0078] The BIOS system's memory diagnostic interface can be invoked to perform memory isolation operations on faulty memory cells based on their physical and logical addresses. After memory isolation, the target server system will not access the faulty memory cell during operation, thus preventing system crashes caused by the memory cell's failure. Memory isolation can be performed simultaneously with alarm message generation. Memory isolation is achieved before staff receive the alarm and take appropriate action, effectively preventing memory failures from impacting the overall server system.

[0079] The server memory fault detection method provided in one or more optional embodiments of this specification further includes:

[0080] If the frequency of the information corresponding to the memory cell does not exceed the preset error frequency threshold within a preset time period, it is determined that the corresponding memory cell is not faulty.

[0081] The data content of the memory cells that do not have faults will be cleared in the internal data.

[0082] The maintenance of data content in the internal database is time-sensitive, and its corresponding maintenance duration is the preset time period. Within the preset time period, if the frequency of the information corresponding to the memory unit does not exceed the preset error threshold, it indicates that although the memory unit has an abnormal situation, it may be due to other reasons triggering a system interrupt signal, which is a false alarm, or the memory unit has already returned to normal. It can be classified as a normal memory unit and considered to be without fault. Therefore, the corresponding data content of the memory unit in the internal memory is cleared, and the internal memory is updated.

[0083] It should be noted that the methods of one or more embodiments of this specification can be executed by a single device, such as a computer or server. The methods of this embodiment can also be applied in a distributed scenario, where multiple devices cooperate to complete the task. In such a distributed scenario, one of these devices may execute only one or more steps of the methods of one or more embodiments of this specification, and the multiple devices will interact with each other to complete the method described.

[0084] It should be noted that the above description describes specific embodiments of this specification. Other embodiments are within the scope of the appended claims. In some cases, the actions or steps recorded in the claims may be performed in a different order than that shown in the embodiments and still achieve the desired results. Furthermore, the processes depicted in the drawings do not necessarily require the specific or sequential order shown to achieve the desired results. In some embodiments, multitasking and parallel processing are also possible or may be advantageous.

[0085] Based on the same inventive concept, and corresponding to any of the above embodiments, this specification also provides a server memory fault detection system, which is applied to a baseboard management controller.

[0086] refer to Figure 6 The server memory fault detection system includes:

If the associated data item exists in the memory database, the associated data item is updated according to the command message. If the associated data item does not exist in the memory database, a new data item is generated according to the data content in the command message.

[0096] In a server memory fault detection system provided in one or more optional embodiments of this specification, the internal database includes multiple data items corresponding to multiple memory units. Each data item includes memory unit coordinates, an error flag, an error count, a physical memory address, and a logical memory address. The memory unit coordinates record the row and column information of the corresponding memory unit, indicating its specific physical location. The error flag indicates whether the corresponding memory unit has triggered a memory error, causing a system interrupt signal.
