[0040] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0041] The terms "first," "second," etc., used in this application's specification are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class, without limiting the number of objects; for example, a first object can be one or more. Furthermore, in the specification, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects have an "or" relationship.

[0042] like Figure 1 As shown, two GPIO interfaces and four resistors (i.e., resistors 1-4) are used for server system configuration identification, and the GPIO interfaces are configured as general-purpose input interfaces.

[0043] For example, the server system configuration can be identified using Table 1.

[0044] Table 1

[0045] System Configuration GPIO_1 GPIO_2 NVME Sku 0 (Resistor 1 not connected, resistor 2 connected) 0 (Resistor 3 not used, resistor 4 used) SSD Sku 0 (Resistor 1 not connected, resistor 2 connected) 1 (Resistor 3 is on, resistor 4 is not on) GPU Sku 1 (Resistor 1 is on, resistor 2 is not on) 0 (Resistor 3 not used, resistor 4 used) Compute Sku 1 (Resistor 1 is on, resistor 2 is not on) 1 (Resistor 3 is on, resistor 4 is not on)

[0046] However, this solution requires multiple GPIO interfaces, which wastes too many GPIO ports. If there aren't enough GPIO ports, an additional IO expansion chip is needed. This not only wastes system layout space but also increases design costs.

[0047] Based on this, this application provides a server system configuration identification method. Since it only requires a variable resistor and a general-purpose input / output interface, the target server system configuration matching the corresponding current range can be queried based on the target current entering the general-purpose input interface of the BMC chip through the variable resistor, which can save system layout space and design cost.

[0048] The server system configuration identification method provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0049] Please refer to Figure 2 , Figure 2 This is a flowchart illustrating the server system configuration identification method provided in an embodiment of this application. Figure 2 As shown, the method may include the following steps:

[0050] Step 201: Obtain the target current entering the general-purpose input interface of the BMC chip through the variable resistor; the variable resistor is connected to the general-purpose input / output interface of the BMC chip; the general-purpose input / output interface is configured as a general-purpose input interface.

[0051] Specifically, only one variable resistor and a general-purpose input / output interface of a BMC chip are used, with the variable resistor connected to the general-purpose input / output interface of the BMC chip, which is configured as a general-purpose input interface. In this way, the target current entering the general-purpose input interface of the BMC chip through the variable resistor can be obtained.

[0052] Step 202: Read the system configuration mapping table. In the system configuration mapping table, various server system configurations correspond one-to-one with multiple current ranges. The resistance value of the variable resistor is configured to make the corresponding target current fall into the corresponding current range.

[0053] For example, the system configuration mapping table is shown in Table 2:

[0054] Table 2

[0055] System Configuration GPIO_1 NVME Sku <![CDATA[1A<I current ≤2A (resistance 1K) SSD Sku <![CDATA[2A<I current ≤3A (5K resistor) GPU Sku <![CDATA[4A<I current ≤5A (10K resistor) Compute Sku <![CDATA[6A<I current (20K resistance)

[0056] As shown in Table 2, the system configuration mapping table includes four server system configurations: NVME SKU, SSDS SKU, GPU SKU, and Compute SKU. The current range corresponding to NVME SKU is 1. current ≤2, the resistance value of the variable resistor is configured to make the corresponding target current I current This current range falls within the specified range; for example, the variable resistor value can be configured to 1KΩ. The corresponding current range for the SSD SKU is 2. current ≤3, the resistance value of the variable resistor is configured to make the corresponding target current I current This current range falls within the specified range; for example, the resistance value of the variable resistor can be configured to 5KΩ. The corresponding current range for GPUSku is 4. current ≤5, the resistance value of the variable resistor is configured to make the corresponding target current I current This current range falls within the specified range; for example, the resistance value of the variable resistor can be configured to 10KΩ. The current range corresponding to the Compute SKU is 6. current The resistance value of the variable resistor is configured to make the corresponding target current I... current If the current falls within this range, for example, the resistance value of the variable resistor can be configured to 20KΩ. ​​​​

[0057] Step 203: Identify the target server system configuration based on the target current and system configuration mapping table.

[0058] Specifically, the target server system configuration that matches the corresponding current range can be retrieved from the system configuration mapping table based on the target current.

[0059] Optionally, for the target server system configuration, the system configuration file corresponding to the server system configuration can be downloaded. This ensures that the system configuration file that matches the server system configuration is downloaded accurately, avoiding errors that may occur during server operation due to mismatch between the server system configuration and the system configuration file.

[0060] The server system configuration identification method provided in this application first obtains the target current entering the general-purpose input interface of the BMC chip through a variable resistor; the variable resistor is connected to the general-purpose input / output interface of the BMC chip; the general-purpose input / output interface is configured as a general-purpose input interface; that is, only one variable resistor and one general-purpose input / output interface are needed; then, the system configuration mapping table is read, in which various server system configurations correspond one-to-one with multiple current ranges; the resistance value of the variable resistor is configured to make the corresponding target current fall into the corresponding current range, and different servers can be configured with different resistance values; finally, based on the target current and the system configuration mapping table, the target server system configuration is identified; since only one variable resistor and one general-purpose input / output interface are needed, and the target server system configuration matching the corresponding current range can be found based on the target current entering the general-purpose input interface of the BMC chip through the variable resistor, system layout space and design costs can be saved.

[0061] In one embodiment, step 201 includes:

[0062] Step 2011: The analog-to-digital converter (ADC) inside the BMC chip converts the analog current signal entering the general-purpose input interface of the BMC chip through the variable resistor into a binary digital current signal, and then obtains the binary digital current signal from the output of the ADC; the input of the ADC is connected to the general-purpose input interface of the BMC chip.

[0063] Specifically, the BMC chip internally incorporates an analog-to-digital converter (ADC). The ADC's input is connected to the BMC chip's general-purpose input interface, and its output is connected to the BMC chip's processor. The ADC converts the analog current signal entering the BMC chip's general-purpose input interface through a variable resistor into a binary digital current signal. The BMC chip's processor then obtains the binary digital current signal from the ADC's output.

[0064] Step 2012: Convert the binary digital current signal from binary to decimal to obtain the target current. The binary digital current signal includes either an integer current value represented in binary or a fractional current value represented in binary; the target current is either the integer current value represented in binary as a decimal integer current value, or the fractional current value represented in binary as a decimal fractional current value.

[0065] For example, suppose the binary integer current value is represented as 11. Converting it from binary to decimal gives 3, then the target current is 3A.

[0066] Assuming the binary fractional current value is represented as 1.101 using fixed-point notation, converting it from binary to decimal gives 1.625, then the target current is 1.625A.

[0067] Step 202 includes:

[0068] Step 2021: Query the target current range that the target current falls into from the system configuration mapping table.

[0069] Step 2022: Query the target server system configuration corresponding to the target current range from the system configuration mapping table.

[0070] For example, assuming the target current is 3A, the target current range that the target current of 3A falls into, as shown in Table 2, is 2A. current ≤3A. Query the target current range (2A) from the system configuration mapping table. current The target server system configuration corresponding to ≤3A) is SSD SKU.

[0071] Assuming the target current is 1.625A, the target current range falling within the target current range of 1A is found by querying the system configuration mapping table shown in Table 2. current ≤2A. Query the target current range (1A) from the system configuration mapping table. current The target server system configuration corresponding to ≤2A) is NVME SKU.

[0072] In this embodiment, the analog-to-digital converter inside the BMC chip can acquire analog current signals and perform analog-to-digital conversion on the analog current signals. The processor inside the BMC chip can convert binary digital current signals from binary to decimal, thereby identifying the target server system configuration based on the system configuration mapping table.

[0073] ​​​​In one embodiment, before step 2021, the method further includes retaining a preset number of decimal places of the target current and performing rounding to obtain the processed target current; step 2021 includes querying the target current range into which the processed target current falls from the system configuration mapping table.

[0074] For example, assuming the target current is 1.625A and the preset number of decimal places is 2, the target current of 1.625A is retained to two decimal places and rounded to obtain a processed target current of 1.63A. Looking up the system configuration mapping table shown in Table 2, the processed target current of 1.63A falls within the target current range of 1A. current ≤2A.

[0075] In this embodiment, if the target current has too many decimal places, it will affect the query efficiency. Only a preset number of decimal places of the target current are retained and rounded to obtain the processed target current. The target current range into which the processed target current falls is then queried from the system configuration mapping table, which can improve the query efficiency.
