[0002] Servers are equipped with network interface cards (NICs) to enable communication and information exchange. Based on server design requirements, NIC performance testing is necessary; only NICs that meet the test requirements can be added to the server's configuration list. NIC performance testing mainly includes latency testing and bandwidth testing. Bandwidth testing plays a primary role in NIC evaluation, making it a very time-consuming task to quickly achieve the required bandwidth performance.

[0003] Existing bandwidth testing methods include: in a computer network system, connecting the network card of the machine under test to the network card of the auxiliary test machine, and using netperf (performance testing tool), iperf (stress testing tool), and iperf3 (stress testing tool) to run on two servers, testing the bandwidth performance of the network card based on its basic configuration. When the network card under test maintains a speed of more than 90% of the bandwidth limit during the specified test time and there are no network card-related errors, the network card is deemed to have passed the test.

[0004] However, due to different network card connection methods, not all network cards can meet the standard.

[0051] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the various embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, those skilled in the art will understand that many technical details are presented in the various embodiments of the present invention to facilitate a better understanding of this application. However, the technical solutions claimed in this application can be implemented even without these technical details and various changes and modifications based on the following embodiments. The division of the various embodiments below is for ease of description and should not constitute any limitation on the specific implementation of the present invention. The various embodiments can be combined with and referenced by each other without contradiction.

[0052] Reference Figure 1 The flowchart of the network card testing method provided in the embodiment of the present invention is shown. Figure 1 The method may include:

[0053] Step 101: Obtain the target connection method of the target network card according to the first command.

[0054] This invention tests the bandwidth performance of the target network card (NIC) by connecting it to the auxiliary NIC within the system. However, since there are multiple connection methods between the two NICs, and the bandwidth performance varies depending on the connection method, to obtain the bandwidth performance of the target NIC, the two NICs are first installed on two servers. Then, a first command is used to obtain the connection method of the target NIC. For example, the NIC connection method can be confirmed by checking the numa_node corresponding to the logical port of the NIC. That is, the numa_node corresponding to the logical port of the target NIC and the auxiliary NIC is obtained. When the numa_nodes of the two NICs are the same, it is determined that the two NICs are not connected across DIEs. When the numa_nodes of the two NICs are different, it is determined that the two NICs are connected across DIEs. Of course, other commands can also be used to obtain other parameter information of the NICs to determine the connection method. This invention does not specifically limit this.

[0055] It should be noted that the connection method is determined by checking the numanodes corresponding to the logical ports of the target network card and the auxiliary network card using the first command. The specific steps include:

[0056] Obtain the numa node of the target network card and the auxiliary network card according to the first command;

[0057] If the numa node is found to be consistent, the target network card and the auxiliary network card are determined to be the first connection method;

[0058] If an inconsistency in the numa node is detected, the target network card and the auxiliary network card are determined to be the second connection method;

[0059] Obtain the target connection method of the target network card based on the first or second connection method.

[0060] The first connection method mentioned above is the connection method that does not cross the DIE, while the second connection method is the connection method that crosses the DIE.

[0061] Therefore, in this embodiment of the invention, after configuring the target network card and the auxiliary network card to two servers respectively, the target connection method of the target network card is obtained according to the first command, so as to obtain the bandwidth performance of the network card under the target connection method and perform optimized configuration.

[0062] Step 102: For the target connection method, obtain the first test result with the highest bandwidth performance among the test results of different stress testing tools. The first test result is obtained based on the target stress testing tool and the first bandwidth.

[0063] In this embodiment of the invention, after determining the target network card connection method, the bandwidth performance of the network card is tested. At this point, a stress testing tool is needed to obtain the test results. Since different stress testing tools will produce different network card bandwidth performance readings, several different stress testing tools are needed to obtain the best bandwidth performance of the network card at this time. For example, common stress testing tools include iperf, iperf3, and netperf. These tools are used on two servers respectively, and the test results are compared to obtain the first test result with the highest bandwidth performance. The first test result includes: the target stress testing tool from which the result was obtained, and the measured network card bandwidth at this time.

[0064] Step 103: If the first bandwidth of the target network card is less than the target threshold, the target stress test tool is used to perform core binding, interrupt binding, and interrupt binding core binding tests. The second test result with the highest bandwidth performance is obtained from the test results. The second test result is obtained based on the target binding method, the number of target threads, the target connection method, and the second bandwidth.

[0065] In this embodiment of the invention, after obtaining the first test result with the highest bandwidth performance through different stress testing tools, if the first bandwidth of the target network card is detected to be less than the target threshold, the network card needs to be configured. Here, the target threshold is the threshold for determining whether the bandwidth of the network card meets the standard. When it is less than this threshold, the bandwidth of the network card does not meet the configuration requirements of the server. At this time, the target stress testing tool with the best network card stress test performance is used to perform core binding test, interrupt binding test, and interrupt binding core test, and the obtained test results are compared to obtain the second test result with the highest bandwidth performance. The second test result obtained at this time includes: the target connection method of the target network card, the target stress testing tool that obtained the result, the target number of threads required to obtain the bandwidth performance, the target binding method at this time, and the second bandwidth.

[0066] It should be noted that when the first test result shows that the first bandwidth is greater than or equal to the target threshold, it means that the network card's bandwidth performance already meets the standard, and no further adjustments are needed. At this point, the first test result can be directly sent to the display screen for staff reference to configure the network card. Specifically, the implementation steps include:

[0067] If the first bandwidth of the target network card is detected to be not less than the target threshold, the first test result will be sent to the display screen.

[0068] Therefore, in this embodiment of the invention, after obtaining the best network card stress test performance tool and the first bandwidth at this time through the stress test tool, the first bandwidth is compared with the target threshold representing the bandwidth qualification standard, and the corresponding operation of directly sending the result to the display screen or further configuring the network card is performed according to the different results obtained.

[0069] Step 104: Send the second test result to the display screen.

[0070] In this embodiment of the invention, the second test result is printed on the display screen for testers to refer to, and the testers can configure the network card accordingly based on the target binding method, target number of threads, target connection method and second bandwidth in the second test result, so that the final bandwidth of the network card can reach the second bandwidth and meet the optimization configuration of the network card.

[0071] The network card testing method provided in this invention obtains the target connection method of the target network card according to a first command. For the target connection method, it obtains the first test result with the highest bandwidth performance among the test results of different stress testing tools. The first test result is obtained based on the target stress testing tool and the first bandwidth. When the first bandwidth of the target network card is detected to be less than the target threshold, the target stress testing tool is subjected to core binding, interrupt binding, and interrupt binding core binding tests to obtain the second test result with the highest bandwidth performance. The second test result is obtained based on the target binding method, the target number of threads, the target connection method, and the second bandwidth. The second test result is sent to the display screen, thereby realizing the network card test information of the network card connection method, the target number of threads, and the target binding method that can achieve the best bandwidth performance, which is sent to the display screen for reference by the staff, greatly saving time and manpower costs.

[0072] Reference Figure 2 The flowchart of the network card testing method provided in the embodiment of the present invention is shown. Figure 2 The method may include:

[0073] Step 201: For the target connection method, generate the third test result based on iperf, the fourth test result based on iperf3, and the fifth test result based on netperf.

[0074] In this embodiment of the invention, the stress testing tools include iperf, iperf3, and netperf. Therefore, a third test result is generated based on iperf, a fourth test result is generated based on iperf3, and a fifth test result is generated based on netperf. Specifically, the test command used to generate the third test result based on iperf is `nohup iperf -c network_interface_IP -i 1 -t 150 -P 11 >>3005.log&`. It should be noted that the parameters in this command mean: `nohup` refers to running in the background, `c` specifies the host IP, `i` refers to the interval between reports in seconds, `t` refers to the test duration, `P` refers to the number of concurrent packet sending threads, and `>>3005.log&` sends the test results to the corresponding file. Therefore, the above command means that the stress testing tool iperf runs in the background on the specified host IP with 11 concurrent packet sending threads for 150 seconds, reporting the obtained results every second, and sending all the reported results to the `3005.log&` file.

[0075] The fourth test result based on iperf3 is generated using the command `nohup iperf3 -c network_port_IP -t150 -i1 -p 5201 --forceflush 5 -P 11|tee -a 5201.log&`. The fifth test result based on netperf is generated using the command `nohup netperf -H network_port_IP -l 150 >>log&`. This invention can also use other stress testing tools to test the network card; however, this invention does not specifically limit the scope of the test results.

[0076] Step 202: Based on the third, fourth, and fifth test results, obtain the first test result with the highest bandwidth performance.

[0077] In this embodiment of the invention, the network card is tested using iperf, iperf3, and netperf, respectively, to obtain third, fourth, and fifth test results. The bandwidth performance parameters in these test results are compared, and the test result with the highest bandwidth performance is selected as the first test result. This includes the target stress testing tool and the first bandwidth. For example, if the bandwidth in the third test result generated by iperf is 8Mbps, the bandwidth in the fourth test result generated by iperf3 is 9Mbps, and the bandwidth in the fifth test result generated by netperf is 10Mbps, since 10Mbps > 9Mbps > 8Mbps, the fifth test result with a bandwidth of 10Mbps is selected as the first test result.

[0078] The network card testing method provided in this invention obtains the target connection method of the target network card according to a first command. For the target connection method, it obtains the first test result with the highest bandwidth performance among the test results of different stress testing tools. The first test result is obtained based on the target stress testing tool and the first bandwidth. When the first bandwidth of the target network card is detected to be less than the target threshold, the target stress testing tool is subjected to core binding, interrupt binding, and interrupt binding core binding tests to obtain the second test result with the highest bandwidth performance. The second test result is obtained based on the target binding method, the target number of threads, the target connection method, and the second bandwidth. The second test result is sent to the display screen, thereby realizing the network card test information of the network card connection method, the target number of threads, and the target binding method that can achieve the best bandwidth performance, which is sent to the display screen for reference by the staff, greatly saving time and manpower costs.

[0079] Reference Figure 3 The flowchart of the network card testing method provided in the embodiment of the present invention is shown. Figure 3 The method may include:

[0080] Step 301: Obtain all numa nodes.

[0081] In this embodiment of the invention, the selected target stress testing tool is subjected to core binding testing. First, the status of the CPU numa node is obtained. For example, the obtained full numa nodes are 1 and 0.

[0082] Step 302: According to the second command, bind the target network card and the auxiliary network card to the full number of numa nodes respectively to generate the full number of core binding methods.

[0083] In this embodiment of the invention, the target network card and the auxiliary network card are bound to all numa nodes according to the second command to generate a full binding method. For example, if the obtained full numa nodes are 1 and 0, then the full binding method includes: binding both the target network card and the auxiliary network card to 0, binding both the target network card and the auxiliary network card to 1, and binding the target network card and the auxiliary network card to 0 and 1 respectively.

[0084] Step 303: Generate full core binding test results based on the target stress testing tool and the full core binding method.

[0085] In this embodiment of the invention, after selecting the corresponding core binding method for both the target network card and the auxiliary network card, the test is performed using the selected target stress test tool to obtain the full core binding test results.

[0086] For example, if the target stress testing tool is selected as iperf, the test command can be used: `numactl --cpunodebind=0 --membind=0 iperf -c network_port_IP -i 1 -t 150 -P`

[0087] The command 11>>3005.log& is used to achieve this. Here, numactl--cpunodebind=0--membind=0 means binding the network card to numa node 0. The following commands have the same meaning as the iperf test commands mentioned above, and will not be elaborated on here.

[0088] The network card testing method provided in this invention obtains the target connection method of the target network card according to a first command. For the target connection method, it obtains the first test result with the highest bandwidth performance among the test results of different stress testing tools. The first test result is obtained based on the target stress testing tool and the first bandwidth. When the first bandwidth of the target network card is detected to be less than the target threshold, the target stress testing tool is subjected to core binding, interrupt binding, and interrupt binding core binding tests to obtain the second test result with the highest bandwidth performance. The second test result is obtained based on the target binding method, the target number of threads, the target connection method, and the second bandwidth. The second test result is sent to the display screen, thereby realizing the network card test information of the network card connection method, the target number of threads, and the target binding method that can achieve the best bandwidth performance, which is sent to the display screen for reference by the staff, greatly saving time and manpower costs.

[0089] Reference Figure 4 The flowchart of the network card testing method provided in the embodiment of the present invention is shown. Figure 4 The method may include:

[0090] Step 401: Obtain the number of cores according to the third command.

[0091] In this embodiment of the invention, the selected target stress testing tool is subjected to interrupt binding test. First, the number of cores is obtained according to the third command, where the third command refers to lscpu.

[0092] It should be noted that lscpu collects CPU architecture information from sysfs and / proc / cpuinfo. The command output includes information such as the number of CPUs, threads, cores, sockets and Nom-Uniform Memory Access (NUMA), cache, etc.

[0093] Step 402: Generate the target number of network ports based on the number of cores.

[0094] In this embodiment of the invention, a target number of network ports are generated based on the number of cores. The number of network ports generated for access is less than the number of cores. For example, if the number of cores is 48, the target number of network ports generated is 16, numbered 0-15.

[0095] Step 403: According to the fourth command, bind the target network card and the auxiliary network card to the target number of network ports respectively to generate the target binding interrupt mode.

[0096] In this embodiment of the invention, the target network card and the auxiliary network card are bound to the target number of network ports according to the fourth command to generate the target interrupt binding method. For example, the network port names corresponding to the generated network ports are 0-15. Then the interrupt binding method is to bind both the target network card and the auxiliary network card to the corresponding network ports.

[0097] Step 404: Generate target-bound interruption test results based on the target stress testing tool and the target-bound interruption method.

[0098] In this embodiment of the invention, after selecting the corresponding interrupt binding method for both the target network card and the auxiliary network card, the test is performed using the selected target stress test tool to obtain the target interrupt binding test results.

[0099] For example, if the target stress testing tool is selected as iperf, it can be achieved using the test command `taskset -c 0-15 iperf -c network_port IP -i 1 -t 150 -P 11 >> 3005.log &`. Here, `taskset -c 0-15` means binding the network card to the network port 0-15. The following commands have the same meaning as the iperf test commands mentioned above, and will not be elaborated on here. The network card testing method provided in this invention obtains the target connection method of the target network card according to a first command. For the target connection method, it obtains the first test result with the highest bandwidth performance among the test results of different stress testing tools. The first test result is obtained based on the target stress testing tool and the first bandwidth. When the first bandwidth of the target network card is detected to be less than the target threshold, the target stress testing tool is subjected to core binding, interrupt binding, and interrupt binding core binding tests to obtain the second test result with the highest bandwidth performance. The second test result is obtained based on the target binding method, the target number of threads, the target connection method, and the second bandwidth. The second test result is sent to the display screen, thereby realizing the network card test information of the network card connection method, the target number of threads, and the target binding method that can achieve the best bandwidth performance, which is sent to the display screen for reference by the staff, greatly saving time and manpower costs.

[0100] Reference Figure 5 The flowchart of the network card testing method provided in the embodiment of the present invention is shown. Figure 5The method may include:

[0101] Step 501: Obtain all numa nodes.

[0102] The method for obtaining the full set of numa nodes in this embodiment of the invention is the same as step 301 above, and will not be described in detail here.

[0103] Step 502: According to the second command, bind the target network card and the auxiliary network card to the full number of numa nodes respectively to generate the full number of core binding methods.

[0104] In this embodiment of the invention, the method of binding the target network card and the auxiliary network card to the full number of numa nodes according to the second command to generate a full number of bound cores is the same as step 302 above, and will not be described in detail here.

[0105] Step 503: Generate full core binding and interruption binding test results based on the target stress testing tool, full core binding method, and target interruption binding method.

[0106] In this embodiment of the invention, core binding and interrupt binding means that the interrupt must be on the corresponding numa node. Therefore, based on the target stress testing tool, the full core binding method, and the target interrupt binding method, the full core binding and interrupt binding test results are generated. For example, this can be achieved by numactl --cpunodebind=0 --membind=0 taskset -c 0-15iperf -c network port IP -i 1 -t 150 -P 11>>3005.log&.

[0107] The network card testing method provided in this invention obtains the target connection method of the target network card according to a first command. For the target connection method, it obtains the first test result with the highest bandwidth performance among the test results of different stress testing tools. The first test result is obtained based on the target stress testing tool and the first bandwidth. When the first bandwidth of the target network card is detected to be less than the target threshold, the target stress testing tool is subjected to core binding, interrupt binding, and interrupt binding core binding tests to obtain the second test result with the highest bandwidth performance. The second test result is obtained based on the target binding method, the target number of threads, the target connection method, and the second bandwidth. The second test result is sent to the display screen, thereby realizing the network card test information of the network card connection method, the target number of threads, and the target binding method that can achieve the best bandwidth performance, which is sent to the display screen for reference by the staff, greatly saving time and manpower costs.
