For example, without departing from the scope of the embodiments of this application, "first XX" may also be referred to as "second XX," and similarly, "second XX" may also be referred to as "first XX." Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of that feature.

[0029] First, some terms involved in this invention will be explained:

[0030] BMC: Baseboard Management Controller. A BMC is an embedded controller used to monitor and manage the hardware status of a server. It can run independently of the operating system and provides remote access and management capabilities. It can monitor and manage server temperature, voltage, fan speed, expansion cards, etc., and typically communicates with external systems via the IPMI (Intelligent Platform Management Interface) protocol.

[0031] I 2 C:I 2 I²C is a commonly used multi-master, bidirectional communication protocol for data transmission between short-distance, low-speed devices. It uses two lines for data transmission: a serial data line (SDA) and a serial clock line (SCL). The I²C protocol is widely used in embedded systems, including for communication between sensors, BMCs, and other peripheral devices.

[0032] Adapter Card: An adapter card is a hardware component typically used to facilitate data and signal transmission between the server motherboard and other devices. Through adapter cards, the motherboard can expand its interfaces to connect with hardware such as RAID cards, GPU cards, and storage devices, thereby enhancing system functionality and scalability.

[0033] MCIO: Multi-Channel I / O. MCIO is an interface type that supports high-speed data transmission, featuring multi-channel data transfer capabilities. It is commonly used to connect motherboards and expansion cards. It provides high-bandwidth I / O channels, enabling connections to high-performance hardware such as RAID cards and GPU cards in high-performance computing devices like servers. MCIO interfaces are typically flexibly configurable; different adapter cards can connect to the motherboard through different MCIO interfaces.

[0034] PCA9548 chip: PCA9548 is an I 2 C-bus switch chip, also known as I 2 C-type multiplexer. This chip allows a single host to control up to 8 I / O lines. 2 C sub-channel, therefore can be in an I 2 Multiple slave devices can be connected to the C-bus without being limited by address conflicts. By controlling the internal registers of the PCA9548 chip, a sub-channel can be selectively enabled or disabled to access slave devices on that channel.

[0035] SKU Number: In server configuration, SKUs can help manage different hardware configurations, such as specific card combinations and wiring methods. Each SKU clearly expresses a specific server configuration, and each SKU has a unique number indicating the specific hardware configuration.

[0036] Sensor ID: The sensor ID is used to identify a specific sensor device, and this ID is unique.

[0037] The following explains the method for marking the physical slots of an adapter card from the perspective of the marking device on the physical slot. Please refer to the relevant documentation. Figure 1 This is a flowchart illustrating a method for identifying the physical slot of an adapter card according to an embodiment of the present invention. The method for identifying the physical slot of the adapter card includes:

[0038] 101. Scan the communication bus to obtain the target combination information corresponding to the target adapter card combination to be connected, wherein the combination information is a set of adapter card numbers in the adapter card combination.

[0039] 102. Determine the target configuration number based on the connection information of the adapter card and the first mapping relationship, wherein the first mapping relationship is a preset mapping relationship between the configuration number and the connection information of the adapter card.

[0040] In this embodiment, the adapter card combination is a combination of adapter cards connected to the server. The adapter card can be connected to the server through the MCIO interface to realize the functional expansion of the server. The server is connected to different adapter card combinations, which are called different server configurations. Pre-defined adapter card combinations that meet different needs are called server configurations. A unique number is set for each server configuration, that is, the first mapping relationship between the configuration number and the adapter card is established.

[0041] The physical slot identification device of the adapter card can obtain the serial number of the adapter card connected to the server by scanning the communication bus, and then obtain the target combination information composed of the serial numbers of all connected adapter cards. Specifically, the connected adapter card can be located by polling the communication bus through the bus device address, and the adapter card number can be read.

[0042] Understandably, the adapter card number is used to identify the adapter card, is unique, and is assigned by the manufacturer during production.

[0043] To facilitate understanding, the following will be combined with Figure 2 Please provide a detailed explanation. Figure 2 This diagram illustrates a specific connection between an adapter card and a motherboard. Adapter cards 10 and 20 are connected to the server's motherboard 30 via the MCIO interface. 2 C bus, motherboard 30 sets BMC, via I 2 C-bus switch chip PCA9548 manages I 2 C-bus channel. Adapter card 10 has physical slots 0, 1, and 2. Expansion devices 11 and 12 are connected to physical slots 1 and 2 respectively. Physical slot 1 is connected to mcio0 via a cable, which is connected to the communication bus I2C16; physical slot 2 is connected to mcio2 via a cable, which is connected to the communication bus I2C18. Adapter card 20 has physical slots 3, 4, and 5. Expansion device 25 is connected to physical slot 5. Physical slot 5 is connected to mcio3 via a cable, which is connected to the communication bus.

[0044] By scanning the communication bus, the BMC locates the adapter cards 10 and 20 connected to the motherboard, reads the adapter card numbers of adapter cards 10 and 20, and thus obtains the number, type, and corresponding communication bus of the adapter cards connected to the motherboard 30, as a server configuration.

[0045] It should be noted that the identification device of the physical slot of the adapter card pre-stores the first mapping relationship. The first mapping relationship can be stored by establishing a two-dimensional array mapping table, and a unique configuration number can be set for each predefined server configuration. The configuration number can be a SKU number.

[0046] Therefore, a unique target configuration number can be determined based on the target adapter card combination and the first mapping relationship.

[0047] In some embodiments, to increase recognition accuracy, steps 101 and 102 can be repeated, specifically including:

[0048] Repeat the step of scanning the communication bus to confirm the target configuration number until a preset number of the same target configuration number are obtained consecutively.

[0049] Set the flag corresponding to the target configuration number to 1;

[0050] If the target configuration number cannot be obtained, the default configuration number is recorded.

[0051] The preset number can be set to 3 times. When the same target configuration number is obtained three times in a row, it can be considered that the correct target configuration number has been obtained. The flag corresponding to the target configuration number is set to 1, which is regarded as the sign that the correct target configuration number has been obtained. The step of scanning the communication bus to confirm the target configuration number can be stopped.

[0052] 103. Determine the target slot connection information corresponding to the target configuration number based on the target configuration number and the second mapping relationship. The second mapping relationship is a predefined mapping relationship between the configuration number and the slot connection information. The slot connection information includes the correspondence between the slot number and the communication bus number. The communication bus number is the number of the communication bus connected to the physical slot of the adapter card corresponding to the slot number.

[0053] In this embodiment, the physical slot identification device of the adapter card pre-stores a second mapping relationship. By establishing a two-dimensional array mapping table, a one-to-one mapping relationship is established between the configuration number and the slot connection information. After obtaining the target configuration number, the physical slot identification device of the adapter card can determine the correspondence between the target slot number and the target communication bus number of the adapter card connected to the server according to the second mapping relationship.

[0054] Understandably, the adapter card connects to the motherboard's communication bus via the MCIO interface. Different types of adapter cards have different physical slot configurations, and there is a fixed one-to-one mapping relationship between the physical slots and the MCIO interfaces, such as... Figure 3 The diagram shows four types of internal connection channels of the adapter card. Therefore, a mapping relationship can be established between the configuration number and the slot connection information based on the connection information of the adapter card.

[0055] 104. Determine the correspondence between the target sensor number and the target slot number based on the target slot connection information and the third mapping relationship. The third mapping relationship is a predefined mapping relationship between the sensor number and the communication bus number. The sensor is a virtual device mounted on the communication bus. The target sensor number is the number of the sensor mounted on the target communication bus. The target communication bus number is the number of the communication bus corresponding to the target slot connection information.

[0056] In this embodiment, the identification device for the physical slot of the adapter card pre-stores a third mapping relationship. By establishing a two-dimensional array mapping table, a one-to-one mapping relationship is established between the communication bus number and the sensor number of the sensor mounted on it. After obtaining the target slot connection information, the correspondence between the target sensor number and the target slot number can be obtained based on the composite mapping of the slot number, communication bus number, and sensor number.

[0057] In some embodiments, the correspondence between the target sensor number and the target slot number is determined based on the target slot connection information and the third mapping relationship, specifically including:

[0058] The sensors are iterated through to obtain the target sensor number;

[0059] Determine if the flag corresponding to the target configuration number is set to 1;

[0060] If it is 1, then the total target communication signal corresponding to the target sensor number is determined according to the target sensor number and the third mapping relationship;

[0061] The target slot number corresponding to the target sensor number is determined based on the target communication total signal and the target slot connection information.

[0062] 105. Based on the correspondence between the target sensor number and the target slot number, write the target slot number into the name of the target sensor.

[0063] In this embodiment, after the identification device of the physical slot of the adapter card obtains the correspondence between the target sensor number and the target slot number, it can rename the name of the target sensor and add the slot number to the target sensor number. The sensor number will be displayed on the sensor interface, so the user can intuitively view the actual position of the physical slot of the adapter card on the sensor interface.

[0064] Compared to related technologies, the method for identifying the physical slot of an adapter card provided by the embodiments of the present invention predefines a first mapping relationship between configuration number and combination information, a second mapping relationship between configuration number and slot connection information, and a mapping relationship between sensor number and communication bus number. By scanning the communication bus, the configuration number is confirmed, the physical slot of the adapter card is identified, and the slot number of the physical slot is written into the name of the sensor. This method has the following advantages:

[0065] Reducing manual intervention and improving operational efficiency: In complex hardware configurations, manually recording slot information is time-consuming and prone to errors.

[0066] By utilizing pre-defined mapping files, the BMC automatically identifies mapping relationships, reducing the need for manual calibration, lowering maintenance costs, and improving management efficiency. It also facilitates visualization of the management interface; by feeding back the identified physical slot locations to the sensor interface, system administrators can intuitively view the actual location of each adapter card, thereby simplifying the management process and improving the visualization and ease of use of expansion card management.
