[0018] In order for those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the drawings and specific embodiments.

[0019] Embodiments of the present application provide an abnormality detection method of a server memory. The method is described in detail in combination with the execution flow of the abnormality detection method of the server memory.

[0020] S101: Obtain the device identifier of at least one extension device in the server, match the device identifier of the at least one extension device with the standard device identifier in the technical specification document, and determine a target extension device.

[0021] Here, the execution subject is BIOS, and the execution timing is before the BIOS runs.

[0022] Here, the expansion device can be a PCIE (Peripheral Component Interconnect Express) device, such as a GPU (Graphics Processing Unit), a smart network card, a RAID (Redundant Array of Independent Disks) card, and the like.

[0023] Among them, at least one expansion device can be a same type device or a non-same type device.

[0024] Among them, the device identifier can be a device ID (Identifier).

[0025] Among them, the expansion device is a device that has requirements for the total capacity of the server.

[0026] Here, the technical specification document can include architecture, core parameters, computing performance, memory specifications, power consumption, heat dissipation, interface specifications, encoding and decoding capabilities, and the like.

[0027] Specifically, the BIOS initializes and enumerates all expansion devices on the server corresponding machine during the startup process, reads the values of the four ID registers in the configuration space of each expansion device, matches the device identifier in the device identifier parameter, and determines the same expansion device.

[0028] In an embodiment, the method can also be used for other firmware, software, and OS (Operating System) in addition to the expansion device.

[0029] In an embodiment, the comparison and matching can be performed by using a hash table or a tree structure.

[0030] S102: Analyze the technical specification document to obtain device parameters of the target expansion device.

[0031] Here, the device parameters can include the offset address of the memory capacity of the expansion device and the memory requirements, and the like.

[0032] S103: Determine the memory capacity of the target expansion device and the memory requirements of the server corresponding to the target expansion device according to the device parameters, wherein the memory requirements of the server include the memory capacity correlation parameter between the target expansion device and the server and the memory installation specification of the server.

[0033] Among them, the memory requirements of the server are obtained by reading the technical specification document, that is, the memory requirements are included in the device parameters.

[0034] Specifically, the memory capacity correlation parameter between the target expansion device and the server can include that the memory capacity of the server must be 1.5 times of the memory capacity of the expansion device.

[0035] Specifically, the memory installation specification can include that the server memory needs to be symmetrically inserted into all CPU memory controller slots.

[0036] In one embodiment, when the memory requirement is not directly included in the device parameter, the theoretical estimated value of the server memory is obtained through information collection and business load estimation; the theoretical estimated value is tested through test environment establishment and benchmark testing, and the test data is analyzed to obtain the configuration suggestion.

[0037] Among them, information collection can include determining the operating system, middleware, database and core application of the expansion device and the server, and can also include querying the recommended configuration of each component.

[0038] Among them, the business load estimation can be quantified by the number of expansion devices, reporting frequency, etc. The memory dynamic demand is calculated according to the continuous overhead and data processing buffer.

[0039] Among them, the theoretical estimated value of the server memory can be obtained according to the fixed overhead and dynamic demand.

[0040] In this way, an effective technical means for system optimization design and dynamic management is realized under the condition of incomplete information.

[0041] S104: According to the memory installation specification of the server, the memory installation mode of each memory bar inserted into the server is detected.

[0042] Here, the memory bar is the physical carrier of the random access memory in the computer.

[0043] Among them, the memory installation mode can include the installation position.

[0044] S105: In response to the detection result of the memory installation mode being normal, the memory capacity of the server is obtained, and the detection result of the server memory capacity is determined according to the memory capacity of the server, the memory capacity correlation parameter between the target expansion device and the server, and the memory capacity of the target expansion device.

[0045] Here, when the test result is abnormal, it can also include what problems will occur, what specific performance, etc. For example, which condition does not meet the memory bar (the memory is not symmetrically inserted, or not all inserted, or both), which device will be affected, and what impact will be produced, such as it may not run to the maximum bandwidth.

[0046] Among them, the detection result can include normal and abnormal.

[0047] Here, the detection result can also include a processing suggestion. The processing suggestion can include how many more same type of memory needs to be inserted on the server to meet the design requirements while ensuring the number of expansion device configurations; or how many expansion device cards need to be reduced to meet the design requirements while keeping the number of existing memory bars on the server unchanged.

[0048] Specifically, the processing suggestion can be displayed on the display screen during the machine startup process by using the corresponding screen display processing function of the BIOS; the processing suggestion can be output to the serial port log of the BIOS by using the serial port output function; and the BIOS sends the abnormal information to the BMC, and the BMC records it in the log through the interaction function between the BIOS and the BMC.

[0049] Specifically, in response to the memory installation mode not passing the detection, a processing suggestion can be generated, which can include symmetrically inserting the memory, expanding the number of memory bars to full configuration, etc.

[0050] In one embodiment, assuming that the expansion device is a GPU, in the case of keeping the number of memories unchanged, the user can remotely access the setting function on the BIOS user interface of the machine to close the upper PCIE device port connected to the corresponding number of GPUs; or use other software, operating system functions, etc. to close the PCIE device port. Specifically, in the BIOS Setup interface, the setting can be performed by using a dedicated Get / SetVariable() control function, or a Redfish command for interacting with the BMC (Baseboard Management Controller, baseboard management controller), system software, etc.

[0051] It should be noted that the present application realizes intelligent identification of the implicit requirements of the expansion device on the server memory by analyzing the technical document of the expansion device, and automatically detects the memory installation specification and capacity during the deployment stage, thereby advancing the fault discovery node from the business runtime to the system deployment stage, effectively eliminating performance and function problems caused by improper memory configuration, realizing the transition from passive troubleshooting to active prevention, and significantly improving the automation level, system reliability and economic benefits of large-scale data center operation and maintenance.

[0052] In some specific embodiments, the device identifier includes a first sub-identifier and a second sub-identifier, the standard device identifier includes a first sub-standard identifier and a second sub-standard identifier, the device identifier of the at least one expansion device in the server is obtained, the device identifier of the at least one expansion device is matched with the standard device identifier in the technical specification document, and the target expansion device is determined, including:

[0053] The first sub-identity of at least one expansion device in the acquisition server is obtained, the first sub-identity is compared with the first sub-standard identity in the technical specification document, and the first expansion device of the same device type is determined in response to the first comparison result being the same, wherein the first sub-identity is used to identify the device type of the expansion device.

[0054] The second sub-identity of each first expansion device is compared with the second sub-standard identity in the technical specification document, and the target expansion device is determined in response to the second comparison result being the same, wherein the second sub-identity is used to identify the device model of the expansion device.

[0055] Here, the device identity of one expansion device can be one or multiple.

[0056] For example, the device identity can include Device ID, Vendor ID, Subsystem ID, and SubsystemVendor ID.

[0057] In some embodiments, comparing the second sub-identity of each first expansion device with the second sub-standard identity in the technical specification document, and determining the target expansion device in response to the second comparison result being the same, includes:

[0058] In response to the presence of multiple second sub-identities, sequentially matching the multiple second sub-identities with the multiple second sub-standard identities in the technical specification document;

[0059] In response to all the multiple second sub-identities passing the matching, determining that the expansion device is the target expansion device.

[0060] Specifically, assuming that the device identity is 4 ID values, the 4 obtained ID values are compared with the 4 ID values in the technical specification document, and only when the 4 ID values are completely matched, the server can determine that the machine corresponding to the server is connected with the expansion device, if only part of the 4 ID values are matched, the matching cannot be completed.

[0061] In this way, false judgments can be prevented.

[0062] In some embodiments, the device parameters include device attribute parameters, and the memory capacity of the target expansion device is determined according to the device parameters, including:

[0063] In response to the device parameters including the memory capacity of the target expansion device and the fixed offset address of the memory capacity, the base address of the configuration space of the target expansion device is determined according to the device attribute parameters of the target expansion device through an expansion device specification algorithm;

[0064] The target address of the memory capacity of the target expansion device is determined according to the base address and the fixed offset address of the memory capacity.

[0065] read the data of the memory capacity of the extension device through a preset access method, and obtain the memory capacity of the target extension device;

[0066] In response to the memory capacity of the target extension device and the fixed offset address of the memory capacity not being included in the device parameters, the memory capacity of the target extension device is determined according to the device identifier of the target extension device through a preset memory capacity library.

[0067] Here, the device attribute parameters can be Bus, Device, Function Number, etc.

[0068] The preset access method can include memory mapping read-write, read-write functions defined in the EFI_PCI_IO_PROTOCOL in the UEFI (Unified Extensible Firmware Interface) specification, etc.

[0069] Specifically, assuming that the extension device is a GPU, the configuration space address of the GPU is calculated through the Bus, Device, and Function Number attributes of the GPU device according to the algorithm defined in the PCIe specification, and then the address position of the video memory is calculated according to the offset address of the display in the configuration space in the technical specification document. Then, the video memory size value is read through memory mapping read-write or read-write functions defined in the EFI_PCI_IO_PROTOCOL in the UEFI specification, etc.

[0070] Here, the preset memory capacity library includes a data structure associated with the device identifier and the memory capacity.

[0071] The memory capacity of the target extension device can not be included in the device parameters, which means that the key parameters of the target extension device cannot be obtained by the BIOS itself, including the BIOS, other firmware and software that cannot obtain and interact with the BIOS.

[0072] In this way, the device configuration space is directly calculated and accessed according to the extension device specification, and the memory capacity data is read in real time, which has the advantages of strong universality and no need to preset information; relying on the preset memory capacity library, the data is obtained by matching the identifier ID, which has higher execution efficiency and better stability.

[0073] In some specific embodiments, the method further comprises:

[0074] Collecting technical specification documents of different extension devices and parsing to obtain standard device identifiers and design parameter data of different extension devices, wherein the design parameter data is related to the memory capacity;

[0075] According to the design parameter data, the memory capacity of the expansion device corresponding to the design parameter data is determined;

[0076] The association data structure of the standard equipment identifier and the memory capacity is constructed;

[0077] The association data structure of different expansion devices is counted to obtain a preset memory capacity library.

[0078] Here, different expansion devices can include different models of the same type of device, or different models of different types of devices.

[0079] Among them, the data structure includes but is not limited to data Table, linked list, etc.

[0080] Among them, the technical specification document of different expansion devices can be collected by artificial investigation, with the help of in-band, out-of-band, operating system command or software, driver and other tools.

[0081] In this way, it is ensured that necessary equipment information can be obtained in the absence of automatic identification capability.

[0082] In some specific embodiments, before detecting the memory installation mode of each memory stick inserted by the server according to the memory installation specification of the server, the method further comprises:

[0083] By accessing the instruction, the memory slot in signal of each memory stick inserted by the server is read;

[0084] According to the memory slot in signal, the in-place condition of each memory stick is determined;

[0085] According to the memory requirement, the memory insertion mode of each in-place memory stick inserted by the server is detected.

[0086] Among them, when the memory stick design includes the in-place signal design of hardware, the in-place signal of hardware is directly read, and when the in-place signal is included in the CPU chip register, the in-place signal is obtained by reading the chip register.

[0087] Specifically, by corresponding instruction, read-write function, accessing chip register or in-place signal, whether the memory stick is installed on the slot is obtained.

[0088] In this way, invalid advanced function detection on the basis of missing or unstable hardware is avoided, and the efficiency and reliability of system startup are effectively improved.

[0089] In some specific embodiments, detecting the memory installation mode of each memory stick inserted by the server according to the memory installation specification of the server comprises:

[0090] Obtain the insertion mode of each memory stick, and detect whether each memory stick is symmetrically inserted;

[0091] In response to the symmetrical insertion of each memory stick, the detection result of the memory installation mode of each memory stick is determined to be normal.

[0092] For example, the memory installation specification can be included in the Intel system architecture, the insertion slot corresponding to one logical unit is set to 0, 1, 2 and 3, and when only one memory stick is inserted, it needs to be inserted into slot 0. If the memory stick is inserted into other slots, the memory installation specification is not met.

[0093] For example, the memory installation specification can be included in the Intel system architecture, one CPU includes multiple logical units, and the insertion slot corresponding to one logical unit is set to 0, 1, 2 and 3. It is required that multiple logical units insert memory sticks into slot 0.

[0094] In some embodiments, the memory capacity of the server is obtained, including:

[0095] The slave address of each memory stick inserted by the server is obtained.

[0096] According to the slave address, the serial presence detect register corresponding to each memory stick is read through the bus protocol.

[0097] The serial presence detect register is parsed to determine the memory capacity of each memory stick.

[0098] According to the memory capacity of each memory stick, the memory capacity of the server is obtained.

[0099] Here, the serial presence detect register is a small electrically erasable programmable read-only memory chip, which is welded on the memory stick and stores key parameter information of the memory stick.

[0100] Here, the bus protocol can be the SMBUS protocol. SMBUS is a two-wire serial bus protocol for system management communication based on I²C (Inter-Integrated Circuit, two-wire serial bus).

[0101] Wherein, the slave address refers to the slave address of the SPD register on the memory stick.

[0102] Specifically, according to the in-place condition of the memory stick, the slave address of the in-place memory stick is obtained.

[0103] Specifically, through the SMBUS protocol, the address / register accessed and parsed by SMBUS access PROTOCL is judged according to the slave address of the memory and the SPD register, so as to obtain the capacity size of each memory stick.

[0104] Specifically, the analysis of the SPD register can include: reading basic information, reading key registers for capacity calculation, calculating data of the key registers, and obtaining the memory capacity of the memory bank.

[0105] In this way, the memory bank configuration of the server is automatically, accurately and non-intrusively discovered and managed.

[0106] In some embodiments, the memory capacity of the server is obtained, and a detection result of the server memory capacity is determined according to the memory capacity of the server, a memory capacity correlation parameter between the target expansion device and the server, and the memory capacity of the target expansion device, including:

[0107] The memory capacity correlation parameter between the target expansion device and the server is analyzed, and a comparison type is determined.

[0108] According to the number of target expansion devices corresponding to the central processing unit and the memory capacity of the target expansion device, a first total memory capacity of the target expansion device is determined, wherein different central processing units correspond to different first total memory capacities.

[0109] According to the number of central processing units in the server and the first total memory capacity, an expansion device total memory capacity of the target expansion device is determined.

[0110] According to the memory capacity of each memory bank and the number of memory banks plugged by the central processing unit, a central processing unit memory capacity of each central processing unit is determined.

[0111] According to the number of central processing units in the server, a server memory capacity of the server is determined.

[0112] In response to the comparison type being the first type, the central processing unit memory capacity of each central processing unit and the first total memory capacity are compared in sequence to determine the detection result of the server memory capacity.

[0113] In response to the comparison type being the second type, the server memory capacity and the expansion device total memory capacity are compared to determine the detection result of the server memory capacity.

[0114] In response to the comparison type being the third type, the central processing unit memory capacity of each central processing unit, the first total memory capacity, the expansion device total memory capacity, and the server memory capacity are compared to determine the detection result of the server memory capacity.

[0115] Wherein, the expansion device connected to one CPU can include one card or multiple cards. One CPU can be connected to one expansion device or multiple expansion devices.

[0116] Specifically, the first total memory capacity of the expansion device can be obtained by acquiring the number of cards of at least one expansion device connected to the CPU, multiplying the number of cards by the memory capacity, and accumulating the values of all expansion devices.

[0117] Specifically, the expansion device total memory capacity of the target expansion device can be obtained by accumulating the first total memory capacity corresponding to each CPU included in the server, or by adding the memory capacities of all target expansion devices to obtain the expansion device total memory capacity on the machine.

[0118] Here, the first comparison type is to compare the correlation between the central processor memory capacity and the first memory capacity of the expansion device. For example, whether the total memory capacity of the memory plugged on each CPU exceeds 1.5 times the first total memory capacity of the connected expansion device.

[0119] When each CPU meets the correlation parameter, the detection result of the server memory is determined to be normal; when there is a CPU that does not meet the correlation parameter, the detection result of the server memory is determined to be abnormal, and improvement suggestions are generated according to the current data and fed back to the user.

[0120] Here, the second comparison type is to compare the correlation between the server memory capacity and the expansion device total memory capacity. For example, whether the total memory capacity plugged on the server exceeds 1.5 x CPU number times the total memory capacity of all expansion devices of this type.

[0121] When the server total memory capacity meets the correlation parameter, the detection result of the server memory is determined to be normal; when the server total memory capacity does not meet the correlation parameter, the detection result of the server memory is determined to be abnormal, and improvement suggestions are generated according to the current data and fed back to the user.

[0122] Here, the third comparison type is to first compare the correlation between the central processor memory capacity and the first memory capacity of the expansion device, and then compare the correlation between the server memory capacity and the expansion device total memory capacity.

[0123] Specifically, when the CPU memory capacity of each CPU meets the correlation parameter, the server memory capacity detection is not performed, and the detection result of the server memory is directly determined to be normal; when there is a CPU memory capacity that does not meet the correlation parameter, an alarm prompt is generated, and the detection of the server memory capacity is continued, when the server memory capacity meets the correlation parameter, the detection result of the server memory is determined to be normal, but an alarm prompt is generated for the CPU memory capacity and fed back to the user, when the server memory capacity does not meet the correlation parameter, the detection result of the server memory is determined to be abnormal and a prompt is generated.

[0124] Thus, the process crash, task unexpected interruption and other problems caused by insufficient memory during long time running are avoided.

[0125] In one embodiment, Figure 2 For the flowchart in the embodiments of the present application, as Figure 2 shown, the flow in the present application includes: investigating the special design requirements of the equipment and the equipment ID; collecting all special equipment and requirements in the BIOS, and matching the equipment ID and the design requirements; the BIOS enumerates all hardware equipment on the server, and matches the collected special equipment ID; determining whether the matching is successful; if not, ending the flow; if yes, obtaining and calculating the design requirement related parameters of the equipment in the comparison; determining whether the equipment design requirements are met according to the related parameters, if yes, ending the flow, if not, explaining the situation to the user and giving processing suggestions; the user receives the information and performs remote processing.

[0126] It should be understood that, although Figure 1 and Figure 2 the steps in the flowcharts are shown in sequence according to the arrows, these steps are not necessarily executed in sequence according to the arrows. Unless otherwise specified herein, the execution of these steps is not strictly limited in sequence, and these steps can be executed in other sequences. Moreover, Figure 1 and Figure 2 at least some of the steps can include multiple sub-steps or multiple stages, which are not necessarily executed at the same time, but can be executed at different times, and the execution sequence of these sub-steps or stages is not necessarily sequential, but can be alternately or alternately executed with other steps or sub-steps or stages of other steps.

[0127] Through the above description of the embodiments, those skilled in the art can clearly understand that the method according to the above embodiments can be realized by means of software and the necessary general hardware platform, of course, it can also be realized by hardware, but in many cases the former is a better embodiment.
