TECHNICAL FIELD

[0001] The present application relates to the technical field of computer, in particular to a network card testing method and device, computer equipment and storage medium. BACKGROUND

[0002] Multi-Host (multiple host administration) technology is a powerful multi-host management and scheduling technology. Using a network card device supporting Multi-Host technology chips, multiple computing nodes and / or multiple storage nodes can be interconnected with the outside world through a single network card, reducing the number of switches, network cards and cables, and using a single network card to provide services for multiple hosts at the same time. This implementation of virtual machine or container cross-host migration and scheduling improves resource utilization and service availability and enables efficient collaboration between multiple computing nodes.

[0003] In order to protect the performance and stability of the network card, the network card needs to be tested. However, the current method for testing the network card is to test the function, performance, pressure and stability of the network card when a single node exclusively uses the network card. Moreover, the testing of the network card mainly focuses on a single test item of the network card. However, in the application scenario of multiple computing nodes and / or multiple storage nodes using a network card supporting Multi-Host technology chips, each node operates independently, and each node has different usage and working conditions for the multiplexed network card at the same time. The current method for testing the network card cannot effectively simulate the actual working conditions of the multiplexed network card when multiple nodes operate the network card, and cannot simultaneously meet the working conditions of the multiplexed network card when each node operates independently.

[0004] Therefore, the related art has the problem that the multiplexed network card cannot be tested to simulate the actual working conditions of the network card when multiple nodes operate the network card differently. SUMMARY

[0005] Therefore, the present application provides a network card testing method and device, computer equipment and storage medium to solve the problem that the multiplexed network card cannot be tested to simulate the actual working conditions of the network card when multiple nodes operate the network card differently.

[0054] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0055] Multi-Host technology is a powerful multi-host management and scheduling technology that achieves efficient connection, management, and scheduling between multiple server nodes through the construction of a centralized control plane or the use of advanced network architecture. The main advantage of this technology is that it enables direct connection between multiple server nodes and a centralized network controller, thereby optimizing data access paths, reducing latency, and significantly improving data transmission efficiency and system density. Using a network card device that supports Multi-Host technology chips, multiple computing nodes and storage nodes can be interconnected with the outside world through a single network card, reducing the number of switches, network cards, and cables. A single network card can provide services for multiple hosts simultaneously. This application can achieve cross-host migration and scheduling of virtual machines or containers, improve resource utilization and service availability, optimize network architecture, reduce network latency and bandwidth bottlenecks, improve overall performance, enable efficient collaboration between multiple computing nodes, and accelerate scientific computing and data analysis tasks. This technology has wide application prospects in cloud computing, data centers, high-performance computing, and other fields. However, current testing methods only test the functionality, performance, stress, and power-on stability of a single server node's exclusive network card. However, in the application scenario of multiple computing nodes and storage nodes sharing a single network card that supports Multi-Host technology chips, each server node operates independently, so there are different usage and working conditions of the shared single network card at the same time. Therefore, the same test operation performed at the same time cannot satisfy the multiple different operation working conditions of each node operating independently in the multi-server node sharing a single network card scenario.

[0056] Based on the above, this invention provides a network interface card (NIC) testing method. Building upon the testing method for a single server node using a dedicated NIC, this method employs mathematical permutations and combinations to randomly generate different combinations of test items. Each test item combination contains test content equal to the number of nodes. These test item combinations are used to test compute and storage nodes. This allows for the execution of different NIC test contents across multiple server nodes using single NICs that support Multi-Host technology chips within the same timeframe, effectively simulating specific scenarios in real-world applications. This achieves the goal of executing different NIC test contents across multiple server nodes using single NICs that support Multi-Host technology chips, covering the operational scenarios of multi-host NIC reuse in real-world applications and improving the technical effectiveness of product development acceptance quality assessment.

[0057] According to an embodiment of the present invention, a network card testing embodiment is provided. It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer device with data processing capabilities, such as a computer, server, etc. Furthermore, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order than that shown here.

[0058] This embodiment provides a network card testing method. Figure 1 This is a flowchart of a network card testing method according to an embodiment of the present invention, such as... Figure 1 As shown, the process includes the following steps:

[0059] Step S101: Obtain the test content set, wherein the test content set contains a first preset number of test contents.

[0060] Specifically, obtain the test content set, where test content refers to test cases. The test content set includes a first preset number of test cases, such as: operating system (OS) restart test, server power on / off test, network card stress test, network card performance test, network card driver upgrade test, etc. The first preset number indicates multiple tests, and its specific value is set according to actual needs.

[0061] Step S102: Obtain a second preset number of test contents to be executed from the test content set, and use the second preset number of test contents to be executed to test the second preset number of nodes sharing the network card respectively. Here, the second preset number is the number of nodes, and the second preset number of test contents to be executed is included in the first preset number of test contents.

[0062] Specifically, the nodes are server nodes, and the server nodes can be divided into computing nodes and storage nodes according to their functions. The second preset number is the number of nodes, for example: 4, 5, and the specific value is set according to actual needs. In the test content set, a second preset number of different test contents are obtained, for example: if the number of nodes is 4, 4 test contents in the test content set are obtained as the test contents to be executed. The second preset number of nodes sharing the network card are tested by using the second preset number of test contents to be executed, for example: controlling 4 nodes to execute 1 test content to be executed respectively. At this time, different nodes execute different test contents.

[0063] It should be noted that different test contents are selected to simulate actual application scenarios. In normal applications, it is rare for multiple server nodes to perform the same type of work, so different test contents are selected to make different nodes execute different test contents, which can better simulate actual application scenarios. However, there is a possibility that two nodes perform the same type of work at the same time. If there is a demand, different nodes can also execute the same test content, for example: 4 nodes, node 1 and node 2 perform operating system restart test. However, this situation can be covered by the whole machine executing OS restart test at the same time.

[0064] The above content is as shown in Figure 2 The test contents for node 1 to node N are selected in the test content set, and different nodes are controlled to execute the corresponding test contents for execution test.

[0065] In step S103, a second preset number of candidate test contents are obtained in the test content set, and it is judged whether the second preset number of candidate test contents are the same as the second preset number of test contents to be executed.

[0066] Specifically, the network card needs to be tested for multiple rounds. After executing the next round of test after step S102, the test contents to be executed need to be reacquired. In order to avoid the situation that the same test content to be executed is selected in the adjacent two rounds of test with a small probability, resulting in a single test and wasting system resources, the test contents to be executed selected in the two rounds of test are compared. If they are the same, the test contents to be executed are reselected in the next round of test.

[0067] In the test content set, a second preset number of candidate test contents are obtained, and it is judged whether the second preset number of candidate test contents are the same as the second preset number of test contents to be executed.

[0068] Step S104: If they are the same, then start executing the subsequent steps from obtaining the second preset number of candidate test contents from the test content set. If they are different, then take the candidate test contents as the new test contents to be executed, replace the test contents to be executed with the new test contents to be executed, and start executing the subsequent steps from testing the second preset number of nodes with the second preset number of test contents to be executed respectively, until the end command is detected, then the process ends.

[0069] Specifically, if the second preset number of candidate test contents are the same as the second preset number of test contents to be executed, it means that the same test contents to be executed have been selected in two adjacent rounds of testing, and the test contents to be executed need to be reselected and step S103 needs to be executed again. If they are different, the candidate test contents are used as new test contents to be executed, and step S102, "using the second preset number of test contents to be executed to test the second preset number of nodes sharing the network card", is executed again up to step S104.

[0070] When the network card testing process meets the cutoff conditions, the node generates an end command. When the end command is detected, the network card test ends. Cutoff conditions include, for example, 20 test rounds, each node executing each test item in the test content set at least once, and the total test time exceeding 10 minutes.

[0071] The above content is as follows Figure 2 As shown, after all nodes have been tested in the first round, test content is reselected for nodes 1 to N in the test content set and compared with the previous test content combination. If they match, new test content is selected; otherwise, testing continues, controlling different nodes to execute the corresponding test content. This round of testing ends, and the above loop repeats.

[0072] The network interface card (NIC) testing method provided in this embodiment obtains a second preset number of candidate test contents from the test content set, and uses these second preset number of test contents to test a second preset number of nodes sharing a NIC. This allows for the execution of different test contents on multiple nodes within the same timeframe, effectively simulating specific scenarios in real-world applications. It covers the working scenarios of multi-host NIC reuse in practical applications, and the multiple rounds of testing improve the acceptance quality of product development. This solves the problem of being unable to simulate the actual working state of the NIC when multiple nodes perform different operations on it during testing of NICs reused by multiple nodes.

[0073] In some alternative implementations, the test content set is obtained, including:

[0074] Obtain the first preset number of test items;

[0075] Generate the first sequence number corresponding to each test item;

[0076] Generate a test content set containing a first preset number of test content items and their corresponding first sequence numbers.

[0077] Specifically, a first preset number of test items are acquired. These test items include, for example: operating system (OS) restart test, server power-on / off test, network card stress test, network card performance test, network card driver upgrade test, network card firmware upgrade test, network card NCSI (Network Controller Sideband Interface, a protocol defined for communication between the baseboard management controller (BMC) and the network card) stress test, network card NCSI and data port interaction test, RoCE (RDMA over Converged Ethernet, a cluster network communication protocol that enables RDMA over Ethernet) / RDMA (remote direct memory access) test, etc. The first preset number represents multiple items; its specific value is set according to actual needs.

[0078] Generate a first sequence number for each test item. For example: the first sequence number for the operating system (OS) restart test is 1, the first sequence number for the server power on / off test is 2, the first sequence number for the network card stress test is 3, the first sequence number for the network card performance test is 4, the first sequence number for the network card driver upgrade test is 5, the first sequence number for the network card firmware upgrade test is 6, the first sequence number for the network card NCSI stress test is 7, the first sequence number for the network card NCSI and data port interaction test is 8, and the first sequence number for the RoCE / RDMA test is 9.

[0079] Generate a test content set containing a first preset number of test content items and their corresponding first sequence numbers.

[0080] In this embodiment, a test content set is generated, which includes a first preset number of test contents and corresponding first sequence numbers. This facilitates the subsequent selection of test contents to be executed from the test content set using the first sequence numbers, ensuring randomness during selection and covering the working scenarios of multi-host multiplexed network cards in practical applications.

[0081] In some optional implementations, determining whether a second preset number of candidate test items are the same as a second preset number of test items to be executed includes:

[0082] Obtain the first sequence number of the candidate test content and the first sequence number of the test content to be executed;

[0083] The candidate test items are sorted according to the first preset order to obtain the first sequence;

[0084] According to the first preset order, the first serial numbers of the test contents to be executed are sorted to obtain a second sequence;

[0085] It is judged whether the first sequence and the second sequence are same. If they are same, it is determined that the second preset number of candidate test contents are same as the second preset number of test contents to be executed.

[0086] Specifically, after steps S101 to S102 are executed, it is considered that a round of test is executed. The next round of test needs to be executed, i.e. steps S103 to S104 are executed. In step S102, the second preset number of test contents to be executed are randomly selected by using the permutation and combination method in mathematics. In step S103, the candidate test contents are selected in the same way. The probability that the candidate test contents are same as the test contents to be executed in step S102 is relatively small.

[0087] However, in order to avoid that the same test contents to be executed are selected in the adjacent two rounds of test with a small probability, the same test contents to be executed are selected in the two rounds of test, the single test is caused, and the system resources are wasted. Therefore, the test contents to be executed selected in the two rounds of test are compared. If they are same, the test contents to be executed are reselected in the next round of test.

[0088] The first serial numbers of the candidate test contents and the first serial numbers of the test contents to be executed are obtained. For example, the first serial numbers of the candidate test contents include 1, 3 and 4, and the first serial numbers of the test contents to be executed include 2, 4 and 9.

[0089] The first preset order is, for example, from large to small. According to the first preset order, the first serial numbers of the candidate test contents are sorted to obtain a first sequence, for example, 134. According to the first preset order, the first serial numbers of the test contents to be executed are sorted to obtain a second sequence, for example, 249.

[0090] It is judged whether the first sequence and the second sequence are same. If they are same, it is determined that the second preset number of candidate test contents are same as the second preset number of test contents to be executed. If they are not same, the second preset number of candidate test contents are not same as the second preset number of test contents to be executed, which can be used as new test contents to be executed.

[0091] In the embodiment, by sorting the first serial numbers of the candidate test contents and the first serial numbers of the test contents to be executed according to the first preset order, and by comparing the two sequences generated, it is determined whether the second preset number of candidate test contents are same as the second preset number of test contents to be executed. The method is convenient and fast, saves the calculation resources, and avoids that the system resources are wasted due to the same test contents to be executed in the adjacent two rounds of test.

[0092] In some optional embodiments, the second preset number of test contents to be executed are obtained in the test content set, and the second preset number of nodes are tested respectively by using the second preset number of test contents to be executed, including:

[0093] The first preset function is used to generate the first preset number of random numbers in a preset range, and the second sequence number of the random numbers is generated;

[0094] The second preset function is used to sort the random numbers according to the size of the random numbers and the second preset sequence, and a random number queue is obtained;

[0095] The first preset number of random numbers in the random number queue are selected as target random numbers;

[0096] The first sequence number same as the second sequence number of the target random number is taken as a target sequence number, and the third preset function is used to obtain the test content corresponding to the target sequence number from the test content set according to the target sequence number, as the test content to be executed;

[0097] The third sequence number of the node is obtained, and the test content to be executed is distributed to the node according to the position of the target random number in the random number queue and the third sequence number, wherein the node is used to execute the distributed test content to be executed in the network card test process.

[0098] Specifically, the first preset function is a function that can generate a plurality of random numbers in a preset range, for example, (0, 1). The first preset function is used to generate the first preset number of random numbers between (0, 1), and the second sequence number of the random numbers is generated according to the sequence of the random numbers, for example, the first preset number is 9, and the 9 random numbers and the corresponding second sequence numbers are 0.73 (R1), 0.96 (R2), 0.05 (R3), 0.44 (R4), 0.51 (R5), 0.32 (R6), 0.89 (R7), 0.21 (R8), and 0.38 (R9).

[0099] The second preset function is a function that can sort numbers according to the second preset sequence. The second preset sequence is, for example, from large to small or from small to large. The second preset function is used to sort the random numbers according to the size of the random numbers and the second preset sequence, and a random number queue is obtained, for example, the second preset sequence is from large to small, and the random number queue is R2, R7, R1, R5, R4, R9, R6, R8, and R3.

[0100] The second preset number is the number of nodes, for example, 4. The first preset number of random numbers in the random number queue are selected as target random numbers, for example, R2, R7, R1, and R5.

[0101] The first serial number same as the second serial number of the target random number is taken as the target serial number, and the target serial number is 2, 7, 1, or 5. The third preset function is a function of querying a query result including the keyword in the search area according to the keyword, for example, using the third preset function, taking the target serial number as the keyword, and taking the test content set as the search area, obtaining the test content corresponding to the target serial number from the test content set according to the target serial number, taking the query result as the test content to be executed, for example, the test content to be executed includes "2. Server power-on / off test", "7. Network card NCSI stress test", "1. Operating system (OS) restart test mapping", and "5. Network card driver upgrade test".

[0102] The third serial number of the node is obtained, for example, the first server node is node 1, and the second server node is node 2. According to the position of the target random number in the random number queue and the third serial number, the test content to be executed is allocated to the node, for example, "2. Server power-on / off test" is executed on node 1 which multiplexes the same Multi-host network card, node 2 executes "7. Network card NCSI stress test", node 3 executes "1. Operating system (OS) restart test mapping", and node 4 executes "5. Network card driver upgrade test".

[0103] In addition, the embodiment can also use a more complex mathematical model to upgrade the selected test item combination selection method to obtain a more random and more simulated actual test combination.

[0104] In the embodiment, random numbers are generated and sorted, the first second preset number of random numbers are selected as target random numbers, the test content corresponding to the second serial number of the target random number is obtained from the test content set as the test content to be executed. Using the method of permutation and combination in mathematics, the test content to be executed is randomly selected, which covers the working scenario of the multi-host multiplexing network card in actual application.

[0105] In some optional embodiments, the method further includes:

[0106] Obtaining a running log of the node executing the test content to be executed;

[0107] According to the running log, the test result state and the test process information of the node are determined;

[0108] Generating a test report containing the test result state and the process information.

[0109] Specifically, during the process of the node executing the test content to be executed, the process information, execution result and other information need to be written into the running log.

[0110] By running the log, it is determined whether the node successfully executes the corresponding to-be-executed test content. If yes, the node test result state in this round is test passed. It is judged whether there is a fault code in the running log. If yes, a fault occurs in the execution process. The time used by the node to execute the to-be-executed test content is determined through the running log. Whether a fault occurs and the time used are included in the test process information. A test report including the test result state and the process information is generated.

[0111] In some optional embodiments, the method further comprises:

[0112] obtaining a test duration and a total amount of to-be-executed test content executed by the node;

[0113] If the test duration exceeds a first preset threshold, or the total amount exceeds a second preset threshold, an end command is generated.

[0114] Specifically, the cutoff condition is, for example, that the test round reaches 20 times, the total amount of to-be-executed test content executed by the node is 100, each node has executed each test content in the test content set at least once, the total test duration exceeds 10 minutes, etc.

[0115] The test duration and the total amount of to-be-executed test content executed by the node in the network card test are obtained. The first preset threshold is, for example, 10 minutes, 15 minutes, etc. The second preset threshold is, for example, 100, 150, etc. The specific value is set according to actual needs. If the test duration exceeds the first preset threshold, or the total amount exceeds the second preset threshold, it indicates that the cutoff condition is met, the network card test is completed, and an end command is generated.

[0116] In this embodiment, the end command is generated according to the test duration and the total amount of to-be-executed test content executed, and the multi-round test on the network card is ended. The network card is tested in multiple rounds, and different test contents are executed in multiple nodes in each test process. This effectively simulates specific scenarios in actual applications, covers the working scenarios of the multi-host multiplexing network card in actual applications, and improves the acceptance quality of product development.

[0117] In some optional embodiments, before the second preset number of nodes are tested by using the second preset number of to-be-executed test contents respectively, the method further comprises:

[0118] determining all nodes sharing the network card;

[0119] installing and configuring a preset test tool on the node, wherein the node executes the to-be-executed test content by using the preset test tool.

[0120] Specifically, all nodes sharing the network card, i.e., server nodes multiplexing the same Multi-host network card, are determined.

[0121] The preset test tools are, for example, Iperf3, Ethtool, Tcpdump, Ping, etc. Iperf3 is a widely used network performance test tool that can measure network bandwidth, throughput and latency. Ethtool is a Linux command line tool for displaying and setting network card parameters. Tcpdump is a tool for capturing network packets and can be used for network monitoring and troubleshooting. Ping is a basic network diagnostic tool for testing network connectivity and response time. When the node is installed and configured with the preset test tools, the preset test tools are used to perform the test content to be performed, such as operating system (OS) restart test, server power-on / off test, network card stress test, network card performance test, network card driver upgrade test, etc.

[0122] In some optional embodiments, the specific process of the node performing the test content to be performed can include steps A1 and A2.

[0123] Step A1, determining the test platform type and test script associated with the test case based on the knowledge base.

[0124] Specifically, the test content to be performed is a test case to be performed. The knowledge base is shown in Table 1.

[0125] Table 1: Knowledge base example

[0126] Test case Component name Test platform type Test script address Run time Use case 1 Component a Type 1 / ceshi / test case1.rb 120s Use case 2 Component a Type 1 / ceshi / test case2.rb 135s Use case 3 Component a Type 2 / ceshi / test case3.rb 68s

[0127] The example data table in Table 1 includes the name of each test case, the name of the component to which it belongs, the required test platform type, the corresponding test script address, and the running time required to run the test case. The test cases in the table can be pre-collected test cases. In the scenario of, for example, automatic regression testing, the test cases in the table can be historical test cases that have already been executed.

[0128] For the test case to be performed, the test platform type and test script associated with the test case are determined based on the knowledge base. For example, the test platform type, test script address, component name to which it belongs, and running information of each test case are determined by querying the knowledge base. The knowledge base can store multiple test cases written in various programming languages, and the test platform on which they run varies according to the test case. The test platform is the running platform of the test case, such as a hardware system and / or an operating system.

[0129] Step A2, determining the test subset to which the test case belongs according to the test platform type; and executing the test case in the test subset based on the test script.

[0130] Specifically, according to the test platform type, a test subset, i.e., a test suite, to which the test case belongs is determined, for example: test cases of the same test platform type are grouped in a test suite. When dividing the test suite, in addition to considering the test platform type of the test case, the running time of each test case can also be considered, so that the running time of all test suites is similar, to adapt to the parallel processing of multiple test suites. In addition, some test cases will cause damage to the system during execution, so the test platforms cannot be shared between these test cases. Therefore, the test suite division not only considers improving the efficiency of the test, but also considers some other internal needs.

[0131] Based on the test script, the test case in the test subset is executed. For example: based on the test platform type, a test environment for the test platform type is instantiated, and for each test suite, a plurality of test scripts associated with a plurality of test cases in the test suite are executed in sequence. During the execution of the test script, the running parameters of the network card are obtained by using the test script. During the test run, parameter substitution is performed, and abnormal handling and fault retry are automatically performed. After completing the execution of the test case, the test results can be collected from the running log, and a test report is generated based on the collected test results.

[0132] In this embodiment, in combination with steps S102 and S103, the test content to be executed is automatically obtained in the test content set, and the control node is used to execute the test content to be executed by using steps A1 and A2, so as to test the network card, realize the automatic generation and execution of the test content, improve the running efficiency of the test, realize reliable fault handling, and output a detailed test report.
