Description

Technical Field

[0001] This invention relates to the field of computer technology, and in particular to a method for adapting the working mode of a network interface card (NIC), a device for adapting the working mode of a NIC, an electronic device, and a readable storage medium. Background Technology

[0002] The NVIDIA BlueField-3 (BF3) network interface card is a 400Gb / s infrastructure computing platform that provides line-speed processing for software-defined networking, storage, and network security. Combining powerful computing capabilities, high-speed networking, and extensive programmability, the BF3 offers software-defined, hardware-accelerated solutions for demanding workloads.

[0003] As demand grows, BF3 network cards are being configured and installed in servers ordered by a wide range of customers. BF3 network cards have at least two working modes: NIC working mode and DPU working mode. Different customers often have different requirements for the working mode of BF3 network cards based on their own business scenarios.

[0004] Therefore, before the server ordered by the customer leaves the factory, it is necessary to adapt the working mode of the BF3 network card pre-installed on the server to ensure that the working mode of the BF3 network card pre-installed on the server matches the customer's requirements.

[0005] The current practice is to have staff manually check whether the working mode of the BF3 network card pre-installed on the customer's pre-installed server matches the customer's requirements before the server leaves the factory. If the working mode of the BF3 network card pre-installed on the customer's pre-installed server does not match the customer's requirements, the working mode of the BF3 network card pre-installed on the customer's pre-installed server will be manually modified to match the customer's requirements.

[0006] However, a customer often orders a large number of servers, and a large number of customers order servers, which leads to a huge workload for staff, high labor costs, and a long processing time, resulting in low efficiency in server delivery. Summary of the Invention

[0007] To address the aforementioned problems, the present invention provides a method for adapting the working mode of a network interface card (NIC), a device for adapting the working mode of a NIC, an electronic device, and a readable storage medium.

[0008] This invention provides a method for adapting the working mode of a network interface card (NIC), applied to a complete system testing system. The complete system testing system is installed in the server to be tested. The method includes:

[0009] Check whether a BF3 network card is installed in the server to be tested;

[0010] If a BF3 network card is installed in the server under test, obtain the PCIe bus number of the BF3 network card installed in the server under test; the PCIe bus number of the BF3 network card includes the unique identifier assigned to the BF3 network card by the PCIe bus in the server under test.

[0011] Obtain the original serial number of the BF3 network card installed in the server under test based on the PCIE bus number of the BF3 network card installed in the server under test.

[0012] Based on the original serial number of the BF3 network card installed in the server to be tested and the stored correspondence, obtain the predetermined working mode of the BF3 network card installed in the server to be tested; the correspondence includes the correspondence between the original serial number of the BF3 network card installed in the server and the predetermined working mode of the BF3 network card installed in the server.

[0013] Get the current operating mode of the BF3 network interface card installed on the server to be tested;

[0014] Compare the current operating mode of the BF3 network interface card (NIC) installed in the server under test with the intended operating mode of the BF3 NIC installed in the server under test to see if there are any differences.

[0015] If the current operating mode of the BF3 network card installed on the server under test differs from the intended operating mode of the BF3 network card installed on the server under test, the operating mode of the BF3 network card installed on the server under test will be changed from the current operating mode to the intended operating mode.

[0016] In an optional implementation, the method further includes:

[0017] After changing the operating mode of the BF3 network card installed on the server under test from the current operating mode to the predetermined operating mode, the step of obtaining the current operating mode of the BF3 network card installed on the server under test is executed again.

[0018] In an optional implementation, the method further includes:

[0019] After changing the operating mode of the BF3 network card installed in the server under test from the current operating mode to the predetermined operating mode, the corresponding entries in the mapping relationship, including the original serial number of the BF3 network card installed in the server under test and the predetermined operating mode of the BF3 network card installed in the server under test, are deleted.

[0020] In an optional implementation, detecting whether the server under test has a BF3 network card installed includes:

[0021] Invoke the first detection command lspci|grep"BlueField-3" pre-set in the whole machine testing system;

[0022] If the result returned by the first detection command is empty, it is determined that the BF3 network card is not installed in the server to be tested;

[0023] Alternatively, if the result returned by the first detection command is not empty, the second detection command "echo $?" can be called based on the result returned by the first detection command.

[0024] If the second detection command "echo $?" returns an empty result, it is determined that the BF3 network card is not installed on the server being tested.

[0025] Alternatively, if the result returned by the second detection command "echo $?" is not empty, it can be determined that the server under test has a BF3 network card installed.

[0026] In one optional implementation, the result returned by the first detection command includes the PCIe bus number of the BF3 network card installed in the server under test;

[0042] If the return values ​​of “INTERNAL_CPU_PAGE_SUPPLIER”, “INTERNAL_CPU_ESWITCH_MANAGER”, “INTERNAL_CPU_IB_VPORT0”, and “INTERNAL_CPU_OFFLOAD_ENGINE” are all the first preset values, then the current working mode of the BF3 network card installed in the server to be tested is determined to be NIC working mode.

[0044] If the return values ​​of “INTERNAL_CPU_PAGE_SUPPLIER”, “INTERNAL_CPU_ESWITCH_MANAGER”, “INTERNAL_CPU_IB_VPORT0”, and “INTERNAL_CPU_OFFLOAD_ENGINE” are all the second preset values, then the current working mode of the BF3 network card installed in the server to be tested is determined to be DPU working mode.

[0045] In an optional implementation, the step of changing the operating mode of the BF3 network card installed in the server to be tested from its current operating mode to a predetermined operating mode includes:

[0046] When the predetermined working mode is NIC working mode, the first modification instruction is invoked according to the PCIE bus number of the BF3 network card installed in the server under test, so as to change the working mode of the BF3 network card installed in the server under test from DPU working mode to NIC working mode.

[0130] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0131] Before introducing the solution of this application, the technical terms that may be involved in the solution of this application will be explained.

[0132] Network Interface Card (NIC) Management System: A management system for configuring and verifying network interface cards (NICs).

[0133] Complete Server Testing System: This system performs complete server testing. It is a server system-level complete server testing system used to ensure the quality of the shipped server. This includes testing whether the hardware / firmware configuration meets the requirements, whether the functions are normal, whether the load component stress test is stable, and whether the overall stability and performance meet the requirements and customer-specified requirements.

[0134] PCIe bus number: Each function in the PCIe bus has a unique identifier. This identifier is the PCIe bus number, which can also be seen as a BDF number, where B represents Bus, D represents Device, and F represents Function.

[0135] PCIe: is a high-speed serial computer expansion bus standard.

[0136] BUS: Bus number. A maximum of 256 bus numbers can be assigned via configuration software. The initial bus number, Bus 0, is typically assigned by hardware to the Root Complex. Bus 0 consists of a virtual PCI bus with integrated endpoints and a virtual PCI-to-PCI bridge (P2P) with hard-coded device and function numbers. Each P2P bridge creates a new bus, and additional PCIe devices can connect to that bus. Each bus must be assigned a unique bus number.

[0137] Device: Device number. PCIe allows up to 32 device numbers on a single PCI bus; however, the point-to-point nature of PCIe means that only a single device can be directly connected to a PCIe link, and that device always ends with device 0. RC and Switch have a virtual PCI bus that allows multiple devices to be "connected" to the bus. Each device must implement Function0 and may contain a set of up to 8 Functions.

[0138] Function: A function number; functions are included in each device. These functions may include hard drive interfaces, display controllers, Ethernet controllers, USB controllers, etc. Devices with multiple functions do not need to be implemented sequentially. For example, a device might implement Functions 0, 2, and 7. Therefore, when software detects a multi-functional device, it must check every possible function to determine which functions are present. Each function also has its own configuration address space for setting associated resources.

[0139] Reference Figure 1 This diagram illustrates a flowchart of an embodiment of a network interface card (NIC) working mode adaptation method provided by the present invention. The method is applied to a complete machine testing system, which is installed in the server to be tested. The method includes:

[0140] In step S101, it is detected whether a BF3 network card is installed in the server to be tested.

[0141] In one embodiment of this application, the first detection command lspci|grep"BlueField-3" pre-set in the whole machine testing system can be invoked.

[0142] Statistics show that when a BF3 network card is installed on the server, the result returned by the first detection command lspci|grep "BlueField-3" is often not empty.

[0143] When the BF3 network card is not installed on the server, the first detection command lspci|grep "BlueField-3" will often return an empty result.

[0144] Thus, after calling the first detection command lspci|grep "BlueField-3" pre-set in the whole machine test system, if the result returned by the first detection command is empty, it is determined that the BF3 network card is not installed in the server to be tested.

[0145] Furthermore, even if the result returned by the first detection command is not empty, it cannot be 100% certain that the server under test has a BF3 network card installed, and further verification is required.

[0146] For example, the second detection command "echo $?" is called in response to the result returned by the first detection command.

[0147] Statistics show that when a BF3 network card is installed on the server, after calling the second detection command "echo $?" in response to the result returned by the first detection command, the result returned by the second detection command is often not empty.

[0148] If the server does not have a BF3 network card installed, after calling the second detection command "echo $?" in response to the result returned by the first detection command, the result returned by the second detection command is often empty.

[0149] Therefore, if the second detection command "echo $?" returns an empty result, it can be determined that the server under test does not have a BF3 network card installed. Alternatively, if the second detection command "echo $?" returns a non-empty result, it can be determined that the server under test has a BF3 network card installed.

[0150] For example, the result returned by the first detection command can be seen in... Figure 2 As shown.

[0151] If a BF3 network card is installed in the server to be tested, in step S102, the PCIE bus number of the BF3 network card installed in the server to be tested is obtained.

[0152] The PCIe bus number of the BF3 network card includes the unique identifier assigned to the BF3 network card by the PCIe bus in the server under test.

[0153] Different devices in a server have different PCIe bus numbers.

[0154] In this application, if a BF3 network card is installed in the server to be tested, the BF3 network card will necessarily have its own PCIe bus number.

[0155] The first test command returns the PCIe bus number of the BF3 network card installed in the server under test. However, the result often includes other information, allowing the PCIe bus number of the BF3 network card to be indexed from the first command's return. For example, the command `lspci|grep"BlueField-3"|awk'{print$1}'` can be used to retrieve the PCIe bus number of the BF3 network card installed in the server under test, as returned by the first test command.

[0156] For example, the result returned by the PCIe bus number retrieval command can be found in [reference needed]. Figure 3 As shown. From Figure 3 As can be seen from the data, there are multiple PCIe bus numbers, which suggests that there are multiple BF3 network cards installed on the server being tested.

[0157] In step S103, the original serial number of the BF3 network card installed in the server under test is obtained based on the PCIE bus number of the BF3 network card installed in the server under test.

[0158] The original serial number of a BF3 network card is set by the manufacturer before the card leaves the factory; it is the card's serial number. Different BF3 network cards have different original serial numbers.

[0159] In the previous scenario of producing a server to be tested, a BF3 network card would be installed on the server to be tested. The server to be tested would then obtain the original serial number of the BF3 network card from the BF3 network card and store the original serial number of the BF3 network card on the server to be tested.

[0160] Then, the original serial number of the BF3 network card can be obtained through commands. For example, to retrieve the original serial number of the BF3 network card installed in the server under test, the command `lspci -vvv -s $[PCIE bus number field]|grep "Serial number"|awk -F':"{print$2}'|sed -e's / / / g'` will return the original serial number of the BF3 network card installed in the server under test.

[0161] For example, the result returned by the command to retrieve the original serial number can be found in [reference]. Figure 4 As shown.

[0162] In step S104, the predetermined operating mode of the BF3 network card installed in the server under test is obtained based on the original serial number of the BF3 network card installed in the server and the stored correspondence. The correspondence includes the correspondence between the original serial number of the BF3 network card installed in the server and the predetermined operating mode of the BF3 network card installed in the server.

[0163] The BF3 network card installed in the server is configured to operate in the mode requested by the customer who ordered the server.

[0164] The whole machine testing system has a corresponding cloud platform.

[0165] In one scenario, a customer can reserve a server through the ordering system. After reservation, the system automatically equips the server with a BF3 network interface card (NIC). The BF3 NIC is already in the manufacturer's inventory, and its original serial number is stored in the database. The system can then retrieve the BF3 NIC's original serial number from this database, linking the server to the automatically assigned BF3 NIC. Furthermore, the system prompts the customer to specify the intended operating mode for the BF3 NIC installed on the server. Once the customer specifies this mode, it is linked to the original serial number of the automatically assigned BF3 NIC.

[0166] The ordering system will transmit the scheduled operating mode of the BF3 network card installed in the server and the original serial number of the BF3 network card automatically assigned to the server to the cloud.

[0167] After obtaining the intended operating mode of the BF3 network card installed on the server and the original serial number of the BF3 network card automatically assigned to the server from the cloud, the original serial number of the BF3 network card automatically assigned to the server and the intended operating mode of the BF3 network card installed on the server can be combined into a corresponding table entry and stored in the correspondence between the original serial number of the BF3 network card installed on the server and the intended operating mode of the BF3 network card installed on the server.

[0168] The same applies to every other server booked through the ordering system.

[0169] Thus, in this step, the corresponding predetermined operating mode of the original serial number of the BF3 network card installed in the server can be found in the correspondence between the original serial number of the BF3 network card installed in the server and the predetermined operating mode of the BF3 network card installed in the server, and this predetermined operating mode can be used as the predetermined operating mode of the BF3 network card installed in the server to be tested.

[0170] The mapping relationship can be located in the cloud corresponding to the whole machine test system. The whole machine test system can remotely retrieve the mapping relationship from the cloud and find the predetermined working mode of the BF3 network card installed in the server to be tested.

[0171] This application allows customers to specify the intended operating mode of the BF3 network interface card (NIC) installed on the server directly in the ordering system when placing their order for the server. This ensures the completeness, accuracy, and reliability of the intended operating mode, guaranteeing that it meets the customer's requirements. The intended operating mode of the BF3 NIC is determined at the initial customer stage and remains unchanged throughout the backend production server process, ensuring accuracy.

[0172] In one example, the correspondence between the original serial number of the BF3 network card installed in the server and the predetermined operating mode of the BF3 network card installed in the server can be shown in the table below. The table includes two columns: the first column is the original serial number of the BF3 network card, and the second column is the predetermined operating mode of the BF3 network card.

[0173]

[0174]

[0175] In step S105, the current operating mode of the BF3 network card installed in the server to be tested is obtained.

[0176] In one embodiment of this application, a working mode acquisition command can be invoked for the PCIe bus number of the BF3 network card installed in the server under test, and the call result returned by the working mode acquisition command can be obtained. Then, the current working mode of the BF3 network card installed in the server under test can be determined based on the returned call result.

[0177] The instructions for obtaining the working mode include:

[0178] "mlxconfig -d [PCIE bus number field] q|grep -iE"

[0179] “INTERNAL_CPU_PAGE_SUPPLIER

[0180] INTERNAL_CPU_ESWITCH_MANAGER

[0181] INTERNAL_CPU_IB_VPORT0

[0182] INTERNAL_CPU_OFFLOAD_ENGINE"".

[0183] In one example, the call results returned by the working mode acquisition instruction include the return values ​​of "INTERNAL_CPU_PAGE_SUPPLIER", "INTERNAL_CPU_ESWITCH_MANAGER", "INTERNAL_CPU_IB_VPORT0", and "INTERNAL_CPU_OFFLOAD_ENGINE".

[0184] Thus, if the return values ​​of "INTERNAL_CPU_PAGE_SUPPLIER", "INTERNAL_CPU_ESWITCH_MANAGER", "INTERNAL_CPU_IB_VPORT0", and "INTERNAL_CPU_OFFLOAD_ENGINE" are all the first preset values, the current operating mode of the BF3 network card installed in the server under test is determined to be NIC operating mode. Alternatively, if the return values ​​of "INTERNAL_CPU_PAGE_SUPPLIER", "INTERNAL_CPU_ESWITCH_MANAGER", "INTERNAL_CPU_IB_VPORT0", and "INTERNAL_CPU_OFFLOAD_ENGINE" are all the second preset values, the current operating mode of the BF3 network card installed in the server under test is determined to be DPU operating mode.

[0185] The first preset value can include 1, and the second preset value can include 0, etc.

[0186] For example, the result returned by the working mode acquisition command can be found in [reference]. Figure 5 As shown. Figure 5 The return values ​​of “INTERNAL_CPU_PAGE_SUPPLIER”, “INTERNAL_CPU_ESWITCH_MANAGER”, “INTERNAL_CPU_IB_VPORT0”, and “INTERNAL_CPU_OFFLOAD_ENGINE” are all 1.

[0187] In step S106, a comparison is made between the current operating mode of the BF3 network card installed in the server under test and the predetermined operating mode of the BF3 network card installed in the server under test to determine if they differ.

[0188] If the current operating mode of the BF3 network card installed in the server under test differs from the predetermined operating mode of the BF3 network card installed in the server under test, in step S107, the operating mode of the BF3 network card installed in the server under test will be changed from the current operating mode to the predetermined operating mode.

[0189] In one embodiment of this application, when the predetermined working mode is NIC working mode, a first modification instruction is invoked according to the PCIE bus number of the BF3 network card installed in the server under test, so as to change the working mode of the BF3 network card installed in the server under test from DPU working mode to NIC working mode.

[0190] The first modification instructions include:

[0191] "mlxconfig -d$BDF S INTERNAL_CPU_MODEL = first preset value\"

[0192] INTERNAL_CPU_PAGE_SUPPLIER = First preset value\

[0193] INTERNAL_CPU_ESWITCH_MANAGER = First preset value\

[0194] INTERNAL_CPU_IB_VPORT0 = First preset value\

[0195] INTERNAL_CPU_OFFLOAD_ENGINE = First preset value\

[0196] INTERNAL_CPU_RSHIM = First preset value.

[0197] Alternatively, in another embodiment of this application, when the predetermined working mode is DPU working mode, a second modification instruction is invoked according to the PCIE bus number of the BF3 network card installed in the server under test, so as to change the working mode of the BF3 network card installed in the server under test from NIC working mode to DPU working mode.

[0198] The second modification instruction includes:

[0199] "mlxconfig -d$BDF S INTERNAL_CPU_MODEL = second preset value\"

[0200] INTERNAL_CPU_PAGE_SUPPLIER = Second preset value\

[0201] INTERNAL_CPU_ESWITCH_MANAGER = Second preset value\

[0202] INTERNAL_CPU_IB_VPORT0 = Second preset value\

[0203] INTERNAL_CPU_OFFLOAD_ENGINE = Second preset value\

[0204] INTERNAL_CPU_RSHIM = second preset value.

[0205] Alternatively, if the current operating mode of the BF3 network card installed in the server under test is the same as the predetermined operating mode of the BF3 network card installed in the server under test, the testing of the operating mode of the BF3 network card installed in the server under test can be terminated.

[0206] Furthermore, after executing step S107 to modify the working mode of the BF3 network card installed in the server under test from the current working mode to the predetermined working mode, steps S105 to S106 are executed again until it is determined that the modified working mode of the BF3 network card installed in the server under test is the same as the predetermined working mode of the BF3 network card installed in the server under test. After that, the test on the working mode of the BF3 network card installed in the server under test can be ended.

[0207] In another embodiment of this application, after changing the operating mode of the BF3 network card installed in the server under test from the current operating mode to the predetermined operating mode, the goal of matching the operating mode of the BF3 network card installed in the server under test with the customer's requirements for the server under test has been achieved. There is no need to further modify the operating mode of the BF3 network card installed in the server under test, nor is it necessary to test the operating mode of the BF3 network card installed in the server under test. Therefore, to save storage space, the corresponding entries for the original serial number and the predetermined operating mode of the BF3 network card installed in the server can be deleted from the mapping relationship between the original serial number and the predetermined operating mode of the BF3 network card installed in the server.
