[0002] In the server field, the server's BMC (Baseboard Management Controller) can use digital twin technology to simulate the overall state of the server: when the server is first powered on or at other times, the BIOS (Basic Input Output System) starts up and runs, performs hardware self-test, and sends all device component data to the BMC; the BMC uses this data to build a digital twin model, and in this way, it can realize real-time monitoring of the server's operating status such as device temperature and device failure.

[0003] In related technologies, the BIOS sends device data to the BMC by using industry-standard hardware data transmission. For example, the BIOS sends raw SMBIOS (System Management BIOS) data to the BMC. However, hardware data such as SMBIOS data is usually binary data, and its parsing depends on industry-standard hardware data specifications, making parsing difficult and resulting in poor readability.

[0025] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0026] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0027] The methods and embodiments provided in this application can be executed on a server, mobile terminal, computer terminal, or similar computing device. Taking running on a server as an example, Figure 1 This is a schematic diagram of the hardware environment for a method of constructing a server digital twin model according to an embodiment of this application. Figure 1 As shown, a server may include one or more ( Figure 1 Only one is shown in the diagram. A processor 102 (which may include, but is not limited to, a microprocessor MCU or a programmable logic device FPGA, etc.) and a memory 104 for storing data are also shown. The server may further include a transmission device 106 for communication functions and an input / output device 108. Those skilled in the art will understand that... Figure 1 The structure shown is for illustrative purposes only and does not limit the structure of the server described above. For example, the server may also include components that are more complex than... Figure 1 The more or fewer components shown, or having the same Figure 1 The different configurations shown.

[0028] The memory 104 can be used to store computer programs, such as application software programs and modules, like the computer program corresponding to the server digital twin model construction method in this embodiment. The processor 102 executes various functional applications and data processing by running the computer program stored in the memory 104, thus implementing the above-described method. The memory 104 may include high-speed random access memory and may also include non-volatile memory, such as one or more magnetic storage devices, flash memory, or other non-volatile solid-state memory. In some instances, the memory 104 may further include memory remotely located relative to the processor 102, and these remote memories can be connected to the mobile terminal via a network. Examples of such networks include, but are not limited to, the Internet, corporate intranets, local area networks, mobile communication networks, and combinations thereof.

[0029] The transmission device 106 is used to receive or send data via a network. Specific examples of the network described above may include a wireless network provided by a communication provider for the computer terminal. In one example, the transmission device 106 includes a Network Interface Controller (NIC), which can connect to other network devices via a base station to communicate with the Internet. In another example, the transmission device 106 may be a Radio Frequency (RF) module used for wireless communication with the Internet.

[0030] According to one aspect of the embodiments of this application, a method for constructing a server digital twin model is provided. The BIOS (Basic Input Output System), as the lowest-level and most direct hardware settings and control manager of the server motherboard, provides the server with more simple and easy-to-use functions. The BIOS is a set of programs embedded in a Flash ROM (Quick Eraser Read-Only Programmer) chip on the motherboard. It stores the computer's most important basic input / output programs, system settings information, power-on self-test programs, and system startup programs. Its main function is to provide the computer with the lowest-level and most direct hardware settings and control. During system startup, in addition to completing the system's hardware self-test and operating system boot, the BIOS also reports asset information of devices such as the CPU (Central Processing Unit), memory, and peripherals to the BMC (Baseboard Management Controller) for the BMC to display to the user via a webpage.

[0031] With the development of technology, digital twin technology has gradually emerged. Digital twins fully utilize data such as physical models, sensor updates, and operational history to integrate multi-disciplinary, multi-physical quantity, multi-scale, and multi-probabilistic simulation processes, completing a mapping in virtual space to reflect the entire lifecycle of the corresponding physical equipment. Digital twins are a concept that transcends reality, and can be viewed as a digital mapping system of one or more important, interdependent equipment systems. Among related technologies, BMC (Battery Management Center) can not only provide asset information management but also utilize digital twin technology to simulate the overall status of servers, monitor equipment temperature, faults, and other operational statuses in real time, and make predictions based on historical data, thereby reducing server failure rates and improving data center operation and maintenance efficiency.

[0032] When a server boots up for the first time, the BIOS performs a hardware self-test, sending all device component data to the BMC. The BMC uses this data to build a digital twin model for asset information management and device monitoring. There are several ways the BIOS sends device data to the BMC. Some use industry-standard hardware data, such as sending raw SMBIOS (System Management BIOS) data. The advantage of this method is that SMBIOS data is generated during BIOS execution and reported to the OS (Operating System), allowing for reuse without regenerating other data. The disadvantage is that SMBIOS data is binary data, parsing depends on the SMBIOS industry standard, making parsing difficult and resulting in poor readability; it also doesn't contain device topology information. Others use the Redfish (a management standard based on HTTPS) protocol to send device information. The advantage is that device information can be directly displayed to the user using the Redfish interface, but this data doesn't contain topology information and is unsuitable for building digital twin models. Still others use vendor-defined binary data. The advantage of binary data transmission is high efficiency, and it can be highly customized according to the model building method, but the disadvantage is poor data readability and maintainability.

[0033] Because the solution in this embodiment obtains the target device data transmitted by the server's basic input / output system through the baseboard management controller, the baseboard management controller parses the target device data to obtain a set of device association information, and the baseboard management controller constructs a digital twin model based on the set of device association information to obtain the server's digital twin model. The target device data in this solution is described using structured markup language, which achieves the purpose of quickly and efficiently parsing the target device data, thereby solving the problems of difficult data parsing and poor data readability in the construction methods of server digital twin models in related technologies.

[0034] The method for constructing a server digital twin model in this embodiment can be applied to scenarios involving the construction of a server digital twin model. Here, a server refers to a type of computer that is faster, has a higher load capacity, and is more expensive than a regular computer. Servers provide computing or application services to other clients (such as PCs, smartphones, ATMs, and even large equipment like train systems) on a network. Servers have high-speed CPU computing power, long-term reliable operation, powerful I / O external data throughput capabilities, and better scalability. Digital twins fully utilize physical models, sensor updates, operating history, and other data to integrate multi-disciplinary, multi-physical, multi-scale, and multi-probability simulation processes, completing mapping in virtual space to reflect the entire lifecycle of the corresponding physical equipment. The server's digital twin model can simulate the overall state of the server, enabling real-time monitoring of the server's operating status, such as equipment temperature and equipment failures.

[0035] Optionally, the method for constructing the server digital twin model in this embodiment can be executed by the server itself. Here, "server" refers to the entire server, including the relevant components within the server that need to execute the method for constructing the server digital twin model, as well as the processor, etc. Alternatively, the method for constructing the server digital twin model in this embodiment can be jointly executed by the BIOS and BMC. Here, when multiple devices jointly execute the method, information can be transmitted between different devices through communication connections, thereby enabling different devices to jointly execute the method for constructing the server digital twin model in this embodiment. In some examples of this embodiment, the method for constructing the server digital twin model is described using the execution by the server as an example.

[0036] See Figure 2 , Figure 2 This is a flowchart illustrating an optional method for constructing a server digital twin model according to an embodiment of this application, as shown below. Figure 2 As shown, the above method includes the following steps:

[0037] Step S202: Obtain the target device data transmitted by the server's basic input / output system through the server's baseboard management controller. The target device data is device association information of a group of devices on the server, described using structured markup language.

[0038] Here, a structured markup language (SML) is a programming language used to describe, define, and organize document structure. It uses tags, elements, and attributes to represent different parts of a document, facilitating parsing and display on different platforms and devices. Common SMLs include HTML (Hypertext Markup Language), XML (Extensible Markup Language), and JSON (JavaScript Object Notation). HTML is a markup language used to create web pages, describing their structure and content; XML is a markup language used to describe data, which can be used to store and transmit data; JSON is a lightweight data-interchange format used to store and transmit structured data. The structured markup languages ​​in this embodiment include, but are not limited to, at least one of the following: XML and JSON.

[0039] A set of devices on a server refers to the various components within the server. In this embodiment, since it is necessary to construct a digital twin model of the server, a set of devices on a server here refers to all the components within the server. A set of devices on a server includes, but is not limited to, at least one of the following: CPU, memory, southbridge, and PCIe (peripheral component interconnect express, high-speed serial computer expansion bus standard).

[0040] In this embodiment, target device data refers to device association information of a group of devices on a server, described using Structured Markup Language. This device association information is required by the server when building a digital twin model. The device association information may include, but is not limited to, at least one of the following: device information for each device in the group, and topology information for the group. Specifically, the device information for each device in the group is required during the construction of the digital twin model for each device, and may include, but is not limited to, at least one of the following: device ID, manufacturer, serial number, functional specifications, and parent device ID (identity document). The topology information for the group represents the topological relationships between each device.

[0041] The target device data is obtained by the server's baseboard management controller from the server's basic input / output system. Here, the baseboard management controller and the basic input / output system are connected in communication. The basic input / output system of the server can transmit the target device data to the baseboard management controller of the server in a way that includes, but is not limited to, at least one of the following: shared memory transmission method and data line transmission method.

[0042] Step S204: The target device data is parsed through the baseboard management controller to obtain a set of device association information.

[0043] The target device data described by the structured markup language is parsed to obtain a set of device association information. Here, the baseboard management controller calls the parsing library to parse the target device data. The parsing library is used to parse the target device data transmitted by the basic input / output system and convert the target device data into device association information that can be used to build a digital twin model for the server. In this embodiment, the parsing library can extract and parse structured data. In this embodiment, the parsing library can be Beautiful Soup (Python library), which can extract data from XML files.

[0044] Step S206: The digital twin model of the server is constructed by the baseboard management controller based on the device association information of a group of devices.

[0045] The baseboard management controller constructs a digital twin model based on the device association information of a group of devices. Here, the construction process of the server's digital twin model can be either directly constructed based on the device association information of a group of devices, or it can be that the digital twin model of each device in the group of devices on the server is constructed separately first, and then the digital twin models of each device are combined to construct the server's digital twin model.

[0046] The baseboard management controller can be configured with preset device models, and a digital twin model can be constructed based on these preset device models. When the construction process of the server's digital twin model is based directly on the device association information of a group of devices, the preset device model can be the preset device model of the entire server. In this case, the server's digital twin model can be constructed based on the preset device model of the entire server and the device association information. When the construction process of the server's digital twin model is based on first constructing the digital twin model of each device in a group of devices on the server separately, and then combining the digital twin models of each device to construct the server's digital twin model, the preset device model can be the preset device model of each device in a group of devices on the server. In this case, the digital twin model of each device in a group of devices on the server can be constructed based on the preset device model of each device in a group of devices on the server and the device association information, and then the digital twin models of each device in a group of devices on the server can be combined to obtain the server's digital twin model.

[0047] The embodiments provided in this application obtain target device data transmitted by the server's basic input / output system through the server's baseboard management controller. The target device data is device association information of a group of devices on the server, described using structured markup language. The baseboard management controller parses the target device data to obtain the device association information of a group of devices. The baseboard management controller constructs a digital twin model based on the device association information of the group of devices to obtain a digital twin model of the server. This solves the problems of difficult data parsing and poor data readability in the construction methods of server digital twin models in related technologies, and improves the construction efficiency of server digital twin models.

[0048] As an optional solution, see [link to relevant documentation]. Figure 3 , Figure 3 This is a flowchart illustrating another optional method for constructing a server digital twin model according to an embodiment of this application, as shown below. Figure 3 As shown, the device association information of a group of devices includes the device information of each device in the group and the topology information of the group of devices. The topology information of the group of devices describes the topological relationships between the devices. The baseboard management controller constructs a digital twin model based on the device association information of the group of devices to obtain a digital twin model of the server, including:

[0049] Step S302: The baseboard management controller calls the preset device model corresponding to each device according to the device information of each device to establish a digital twin model of each device.

[0050] In this implementation, the device association information of a group of devices includes the device information of each device in the group of devices and the topology information of the group of devices. Here, the device information refers to the relevant information that each device in the group of devices needs to use in the process of building a digital twin model. The device information may include, but is not limited to, at least one of the following: device ID, manufacturer, serial number, functional specifications, and parent device ID.

[0051] The baseboard management controller calls the preset device model corresponding to each device based on the device information of each device to build a digital twin model of each device. Here, the preset device model corresponding to each device is a preset model that each device needs to use in the process of building the digital twin model of each device. The specific process of building the digital twin model of the device based on the device information and the preset model has been described in related technologies and will not be repeated here.

[0052] Step S304: The digital twin model of each device is combined into a digital twin model of the server by the baseboard management controller according to the topological relationship between the devices indicated by the topology information of a set of devices.

[0053] The topology information of a set of devices is the information needed to combine the digital twin models of each device in a set of devices on the server into the digital twin model of the server. The topology information includes the topological connection relationship between each device in a set of devices on the server. Based on the topology information of a set of devices, the baseboard management controller can combine the digital twin models of each device into the digital twin model of the server.

[0054] The device association information provided in this application includes device information and topology information. A digital twin model of each device is constructed based on the device information. Based on the digital twin model of each device and the topology information, a digital twin model of the server is obtained. The baseboard management controller can quickly construct a digital twin model of the entire server using the topology information, saving the time of the baseboard management controller to re-extract the topology relationship and improving the efficiency of the baseboard management controller in constructing the digital twin model.

[0055] As an optional approach, the baseboard management controller combines the digital twin models of each device into a digital twin model of the server according to the topological relationships between a set of devices indicated by the topology information of a set of devices, including:

[0056] S11: In the event that the device information of the target device in a set of devices is damaged, the digital twin models of the other devices in the set of devices, except for the target device, are combined into a digital twin model of the server by the baseboard management controller according to the topological relationship between the devices indicated by the topological information of the set of devices.

[0057] Here, the target device refers to the device whose device information is corrupted in a group of devices.

[0058] In this embodiment, if the device information of the target device in a group of devices is damaged, it means that the baseboard management controller cannot build a digital twin model of the target device based on the device information of the target device. Since the topology information of a group of devices includes the upper-level or lower-level devices of the target device, the baseboard management controller can combine the digital twin models of the other devices in the group of devices, excluding the target device, into a digital twin model of the server based on the topology relationship between the devices.

[0059] Through the embodiments provided in this application, in the event that the device information of the target device in a group of devices is damaged, a digital twin model of the server can be constructed based on the topology information of the group of devices, thereby increasing the reliability of the method for constructing a digital twin model of the server.

[0060] As an optional approach, the device information for each device includes a parent device identifier that indicates the parent device of each device; before constructing a digital twin model of the server through the baseboard management controller based on the device association information of a set of devices, the method further includes:

[0061] S21: If the topology information of a group of devices is corrupted, update the topology information of the group of devices according to the parent device identifier in the device information of each device to obtain the updated topology information of the group of devices.

[0062] In this embodiment, the updated topology information of a set of devices refers to the topology information of a set of devices that are intact and undamaged.

[0063] Each device's device information includes a parent device identifier that indicates the parent device of each device. That is, the topology relationship is redundant in the topology information and detailed information. If the topology information of a group of devices is corrupted, the topology information of the group of devices is updated according to the parent device identifier in the device information of each device to obtain the updated topology information of the group of devices. Since each device's device information includes a parent device identifier that indicates the parent device of each device, that is, each device's device information includes the topology relationship between the device and other devices, if the topology information of a group of devices is corrupted, the topology information of the group of devices can be updated based on the device information of each device in the group to obtain the updated topology information of the group of devices.

[0064] Through the embodiments provided in this application, in the event of corrupted topology information, the topology information is updated using the device information of each device in a group of devices to obtain intact topology information, thereby increasing the reliability of the method for constructing a server digital twin model.

[0065] As an optional solution, see [link to relevant documentation]. Figure 4 , Figure 4 This is a flowchart illustrating another optional method for constructing a server digital twin model according to an embodiment of this application, as shown below. Figure 4 As shown, before obtaining the target device data transmitted by the server's basic input / output system through the server's baseboard management controller, the method further includes:

[0066] Step S402: During the initialization of a group of devices on the server, the device information of each device in the group is obtained through the basic input / output system to obtain a device linked list. The device information of each device includes a parent device identifier used to indicate the parent device of each device.

[0067] In this embodiment, a set of devices on the server is initialized using a Basic Input / Output System (PIS). This initialization process can be performed when the server is powered on. The PIS is used to obtain device information for each device in the set, resulting in a device list. Each device's information includes a parent device identifier indicating the parent device of that device; that is, each device's information contains the topological relationships between the devices in the set. A device list is a data structure used to store and manage information. It consists of multiple nodes, each node containing information about a device and pointing to the next node. The device list can be used to manage the connection order of devices and to find specific device information. Here, the device list stores the device information for each device in the set on the server.

[0068] Step S404: After all devices in a group have been initialized, the device list is traversed through the basic input / output system, and the device information of each device and the topology information of the group of devices are described by the structured markup language to obtain the target device data.

[0069] After all devices in a group have been initialized, the device list is traversed through the basic input / output system to obtain the device information of each device and the topology information of the group of devices. The device information of each device and the topology information of the group of devices are described through structured markup language to obtain the target device data.

[0070] Step S406: Transmit the target device data to the board management controller via the basic input / output system.

[0071] After obtaining the target device data, the target device data is transmitted to the baseboard management controller through the basic input / output system. Here, the data transmission method includes, but is not limited to, at least one of the following: shared memory transmission method and data line transmission method.

[0072] The embodiments provided in this application describe the process of acquiring target device data, which increases the stability of the method for constructing a server digital twin model.

[0073] As an optional solution, data from the target device is transmitted to the board management controller via a basic input / output system, including:

[0074] S31: The target device data is transmitted to the baseboard management controller via shared memory through the basic input / output system. The shared memory is the memory used for data transmission between the basic input / output system and the baseboard management controller.

[0075] In this embodiment, the specific steps for transmitting target device data to the baseboard management controller via shared memory through the basic input / output system can be as follows: the baseboard management controller maps memory to the basic input / output system for use as shared memory; the basic input / output system and the baseboard management controller determine the offset address of the target device data; and the basic input / output system stores the target device data in the shared memory at the specified offset address for the baseboard management controller to read by accessing the shared memory.

[0076] The embodiments provided in this application utilize shared memory to transmit target device data, thereby increasing the data transmission speed between the basic input / output system and the baseboard management controller, and thus improving the efficiency of building the server's digital twin model.

[0077] As an optional solution, the target device data is parsed through the baseboard management controller to obtain a set of device association information, including:

[0078] S41: The target device data is parsed by calling the parsing library corresponding to the structured markup language through the baseboard management controller to obtain a set of device association information, wherein the structured markup language is at least one of the following: Extensible Markup Language, JavaScript Object Graph; the obtained set of device association information is stored in the database of the baseboard management controller.

[0079] In this embodiment, the parsing library is used to parse the target device data transmitted by the basic input / output system and convert the target device data into device association information that can be used to build a digital twin model for the server. In this embodiment, the parsing library can extract and parse structured data. The parsing library in this embodiment can be Beautiful Soup (Python library), which can extract data from XML files.

[0080] After obtaining the device association information of a set of devices, the device association information of the set of devices is stored in the database of the baseboard management controller. When it is necessary to build a digital twin model of the server, the device association information of the set of devices in the database of the baseboard management controller is extracted, and the digital twin model of the server is built based on the device association information of the set of devices.

[0081] Optionally, using Structured Markup Language (SML) as the extensible markup language, taking the device association information of a group of devices, which includes the topological relationships between a group of devices, as an example, the following is the target device data of the device association information of a group of devices described using extensible markup language:

[0082] <cpu0>

[0083] <pcie>

[0084] <Device category=”Network”> ID_000

[0085] <Device category=”Network”> ID_001

[0086] <switch>

[0087] <Device category=”GPU”> ID_002

[0088] <Device category=”GPU”> ID_003

[0089] < / switch>

[0090] < / pcie>

[0091] < / cpu0>

[0092] After the baseboard management controller calls the parsing library corresponding to the Extensible Markup Language (which can be BeautifulSoup) to parse the target device data, the following topology can be obtained:

[0093] CPU0

[0094] |--NetworkID000

[0095] |--NetworkID001

[0096] |--Switch

[0097] |--GPUID002

[0098] |--GPUID003

[0099] Here, CPU0 is the parent device of NetworkID000, NetworkID001, and Switch, and Switch is the parent device of GPUID002 and GPUID003.

[0111] Step 9: Combine the digital twin models of each device to obtain the digital twin model of the server;

[0115] S2: After all devices are initialized, a binary data linked list of device details is obtained;

[0116] S3: Traverse the binary data of device details and construct the device topology information XML file and the device details XML file;

[0117] S4: Pass the device topology information XML and device details XML to the BMC via shared memory;

[0118] S5: The BMC parses the device topology information XML and device details XML to obtain raw data, which is then stored in the database for further processing.

[0119] S6: Based on the detailed device information stored in the database, extract and construct digital twin models of each device from the preset model library;

[0120] S7: Based on the device topology information stored in the database, combine the device models constructed in step S6 to generate the server whole machine model;

[0121] S8: Monitor and simulate the model for user use.
