DETAILED DESCRIPTION

[0011] The following will be combined with the accompanying drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0012] It should be noted that, in the description of this application, the terms "comprises," "includes," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or elements inherent to such process, method, article, or device. The terms "first," "second," etc., in this application are used to distinguish similar objects, and are not used to describe a particular order or sequence.

[0013] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0014] Smart NICs primarily include encryption / decryption, firewall, TCP / IP, and HTTP processing, making them ideal for high-traffic web servers. They offload all network, security, and storage functions from the host server, freeing up valuable processing power so the server can focus on running critical applications and operating systems more efficiently. Smart NICs can also perform virtualization, load balancing, and data path optimization.

[0015] SmartNICs are programmable. SmartNICs are flexible and programmable network cards that can perform network traffic processing workloads typically performed by CPUs, such as TCP / IP and HTTP processing. SmartNICs require the assistance of FPGAs. The core of SmartNICs is to assist the CPU in processing network loads through FPGAs (field programmable gate arrays), thereby achieving hardware acceleration. SmartNICs support local programming of the data plane and control plane, allowing users to customize network functions according to their needs. SmartNICs typically contain multiple ports and internal switches, enabling fast data forwarding and intelligent mapping to relevant applications. SmartNICs can detect and manage network traffic, providing real-time network monitoring and troubleshooting capabilities.

[0016] The network card stability testing method provided in this application can be applied to Figure 1In the application environment shown, terminal 102 communicates with server 104 via a network. Terminal 102 can test the stability of the network card in server 104. The network card includes a controller, preferably an FPGA (field programmable gate array). Terminal 102 can be, but is not limited to, various personal computers, laptops, smartphones, tablets, and portable wearable devices. Server 104 can be implemented as a standalone server or a server cluster consisting of multiple servers.

[0017] like Figure 2 As shown, an embodiment of the present application provides a network card stability testing method. The controller of the network card is burned with a normal installed version of network firmware and an abnormal mirror version of network firmware. The network card stability testing method includes the following steps: Step S1, in response to the network card running a normal installed version of network firmware, performing a service usage performance test on the network card and monitoring the network performance data flow value of the network card; Step S2, determining the service usage performance test result of the network card according to the network performance data flow value; Step S3, in response to the normal installed version network firmware completing the service usage performance test, setting the normal installed version network firmware to invalid, and restarting the network card to run the abnormal mirror version network firmware; Step S4, in response to the network card running an abnormal mirror version of the network firmware, performing a storage network flow test on the network card and monitoring the bandwidth value of the network card; Step S5: determining the storage read / write performance test result of the network card according to the bandwidth value.

[0018] The normal installed version of network firmware is the service version that matches the network card's properties, while the abnormal mirror version of network firmware is the service version that does not match the network card's properties. For example, if an FM8 rpd file is written to an FM7 device, the FM8 rpd file will be the abnormal mirror version of network firmware. The rpd file is the programming data file.

[0019] In this embodiment, a normal installed version of network firmware and an abnormal mirror version of network firmware are burned into the controller of the network card. When the normal installed version of network firmware and the abnormal mirror version of network firmware are running, a network card stability test is performed. The abnormal mirror version of network firmware can be set according to actual needs, and comprehensive test data can be obtained so that performance test results can be compared and analyzed based on different versions of test data to identify defects in the network card, thereby achieving a comprehensive test of the network card stability.

[0020] like Figure 3 As shown, in this embodiment, the network card stability testing method further includes: Obtain the storage space of the controller in the network card to be tested, and divide the storage space into tool reserved space, image file space, and application file space according to the storage address; The abnormal image version network firmware is burned in the image file space. The abnormal image version network firmware has functions including flash memory burning, network port and communication interface. The abnormal image version network firmware does not match the device type of the network card. Burn the normal installation version of the network firmware in the application file space. The normal installation version of the network firmware matches the device type of the network card.

[0021] like Figure 3 As shown in the figure, an abnormal image version of network firmware is written at the Flash start address 0x01400000 (general).

[0022] In this embodiment, the network card stability testing method further includes: Determine whether the normal installed version network firmware and the abnormal mirror version network firmware exist independently of each other; In response to the normal installed version network firmware and the abnormal mirror version network firmware not existing independently, the normal installed version network firmware and the abnormal mirror version network firmware are combined to produce a first programming data file; when the normal installed version network firmware or the abnormal mirror version network firmware is upgraded, the corresponding network firmware in the first programming data file is upgraded; In response to the fact that the normal installed version network firmware and the abnormal mirror version network firmware exist independently of each other, the normal installed version network firmware is made into a second programming data file; when the normal installed version network firmware is upgraded, the second programming data file is upgraded; when the abnormal mirror version network firmware is upgraded, the abnormal mirror version network firmware in the mirror file space is upgraded.

[0023] As shown in the figure, in the topology diagram of the storage network flow test, the host, network card, switch and test server are interconnected.

[0024] First, modify grub (Multi-OS Boot Manager) to configure SOC (Controller) huge pages and IOMMU (Input-Output Memory Management Unit).

[0025] In the grub (Multi-OS Boot Manager) configuration file (vi / etc / default / grub) of the controller (SOC), add default_hugepagesz=1Ghugepagesz=1G hugepages=7 iommu=pt intel_iommu=on to the end of kernel cmdline. Update the grub file: grub2-mkconfig -o / boot / efi / EFI / ctyunos / grub.cfg; Restart the system: reboot.

[0026] Secondly, install the spdk (storage application) software and configure it in the same directory as the compressed package soc_sw.tar of the software source file.

[0027] Finally, check the running status of the FPGA on the SOC side under the abnormal image version network firmware (Golden version): After the SOC side of the network card (SmartNIC) is powered on, it defaults to the normal installed version network firmware (APP image). If the normal installed version network firmware is invalid, it directly enters the abnormal image version network firmware. Log in to the SOC side of the network card (SmartNIC) and operate the mailbox remote system update (RSU) command to switch. After the remote system update (RSU), you can rescan the PCIE device by rescanning or restarting the network card, but you cannot shut down the network card. The shutdown operation will default to the normal installed version network firmware.

[0028] like Figure 4 As shown, in this embodiment, the network card stability testing method further includes: In response to the upgrade of the normal installed version network firmware, performing an in-band update on the abnormal mirror version network firmware according to the update content of the normal installed version network firmware, obtaining a manager associated with the normal installed version network firmware, and performing an out-of-band update on the manager; In response to burning the abnormal image version network firmware in the image file space or upgrading the abnormal image version network firmware, the network card is restarted.

[0029] like Figure 4 As shown, in this embodiment, the network card stability testing method further includes: In response to the abnormal image version network firmware being upgraded, the normal installed version network firmware is updated in-band according to the updated content of the abnormal image version network firmware, the manager (BMC) associated with the abnormal image version network firmware is obtained, and the manager is updated out-of-band.

[0030] The host configuration method is as follows: a. Add default_hugepagesz=1G hugepagesz=1G hugepages=20 to the end of kernel cmdline in the grub configuration file (vi / etc / default / grub) on the backend host, save the configuration, and reboot. b. Install the SPDK (storage application) RPM package on the cloud disk backend host: rpm -ivh spdk-22.01-4.ctl2.x86_64.rpm; c. Execute kill -9 `pidof nvmf_tgt` to kill the existing process (if it exists); d. Then execute the start-nvmf.sh script to start the nvmf target process (you need to change the target_ip in the script to the corresponding IP in advance).

[0031] Among them, the controller in the network card configures the IP and ensures that the soc and target ip can be connected: a. Configure the network card IP address: ifconfig ens6f7 10.61.0.21 netmask 255.255.248.0 up; b.systemctl restart bss.service starts the SPDK process; c. Then execute the attach-nvme-disk.sh script to attach the disk (you need to change the target_ip in the script to the IP address configured on the storage backend in advance).

[0032] Among them, storage network traffic test: a.Configure IP Configure host pf0 (MAC address is 00:01:02:03:04:00) and the corresponding network interface IP address is 12.0.0.3 / 24; The host network card IP address is configured as 12.0.0.8 / 24; Configure the MTU (maximum transmission unit) of the host to be tested to 4000: ifconfig ethx mtu 4000; b. Flow test Run on the test host: iperf -s -P 4 -D; Run on the host: iperf -c 12.0.0.8 -i 1 -t 10000 -P 4.

[0033] In this embodiment, in response to the normal installed version network firmware completing the service usage performance test, setting the normal installed version network firmware to invalid, and restarting the network card to run the abnormal mirror version network firmware includes: Set to control the network card to start the normal installed version of the network firmware when the network card is turned on; In response to switching the normal installed version network firmware to the abnormal mirror version network firmware, the version switch is triggered through the email remote system update command, the normal installed version network firmware is controlled to be invalid to shut down the normal installed version network firmware, the network card is switched to the abnormal mirror version network firmware, and after the function is switched, the network card is restarted to rescan the solid-state hard disk device.

[0034] In which, in response to the network card being powered on again after being powered off, the network card is controlled to start the normal installed version of the network firmware.

[0035] like Figure 5 As shown, in this embodiment, in response to running an abnormal mirror version of network firmware in the network card, performing a storage network flow test on the network card and monitoring the bandwidth value of the network card include: The types of storage network traffic tests for the network card include storage traffic test and network traffic test. Perform storage traffic testing in response to testing the network card's storage read / write performance, throughput limit, or latency; In response to testing the bandwidth capacity, packet loss rate, delay jitter or protocol processing capability of the network card, a network flow test is performed.

[0036] Specifically, such as Figure 5 As shown in the figure, the storage flow test includes: A storage application (SPDK), a first physical network port function module (PF1), and a second physical network port function module (PF2) are provided in a controller (SOC) in the network card, and the first physical network port function module and the second physical network port function module are connected through the storage application; A first address table (mac0) and a second address table (mac1) are set in the network card, and the first address table and the second address table are connected to the accompanying test server through a switch; The host machine (Host) is configured to include a paravirtualized block device driver (virtio-blk) and a paravirtualized network communication driver (virtio-net), the first address table is connected to the second physical network port function module, the first physical network port function module is connected to the paravirtualized block device driver (virtio-blk), and the paravirtualized network communication driver (virtio-net) is connected to the second address table; After the companion test server is connected to the network card through a switch, the network card sends a one-way data stream to the paravirtualized block device driver (virtio-blk). The host transmits data back to the network card through the reverse link. The companion test server monitors the data flow and bandwidth and determines whether it exceeds the preset bandwidth value. If so, it records the network card's storage read and write performance as qualified. Otherwise, it records the network card's storage read and write performance as unqualified. The accompanying test server is connected to the switch and connected to the paravirtualized network communication driver (virtio-net) through the second address table. The accompanying test server monitors the network performance data flow and determines whether it is greater than the preset bandwidth value. If so, it records the storage read and write performance of the network card as qualified, otherwise it records the storage read and write performance of the network card as unqualified.

[0037] The paravirtualized block device driver (virtio-blk) is used in virtualization technology to implement high-performance block devices (such as virtual disks). Part of the virtio standard framework, it significantly improves disk performance in virtualized environments by optimizing storage I / O communication between virtual machines (VMs) and hosts.

[0038] Among them, the paravirtualized network communication driver (virtio-net) is a paravirtualization driver used for network communication in a virtualized environment. It provides efficient network data transmission between the host and the virtual machine (Guest) through the virtio framework.

[0039] It is understandable that, in response to the normal installation version of the network firmware running in the network card, the service usage performance test of the network card is performed, and the network performance data flow value of the network card is monitored. The storage network flow test method of the network card can be the same as the storage network flow test when the abnormal image version of the network firmware is running, including: A storage application (SPDK), a first physical network port function module (PF1), and a second physical network port function module (PF2) are provided in a controller in the network card, and the first physical network port function module and the second physical network port function module are connected through the storage application; A first address table (mac0) and a second address table (mac1) are set in the network card, and the first address table and the second address table are connected to the accompanying test server through a switch; The host machine (Host) is configured to include a paravirtualized block device driver (virtio-blk) and a paravirtualized network communication driver (virtio-net), the first address table is connected to the second physical network port function module, the first physical network port function module is connected to the paravirtualized block device driver (virtio-blk), and the paravirtualized network communication driver (virtio-net) is connected to the second address table; After the companion test server is connected to the network card through a switch, the network card sends a one-way data flow to the paravirtualized block device driver (virtio-blk). The host sends data back to the network card through the reverse link. The companion test server monitors the data flow and bandwidth and determines whether it exceeds the preset bandwidth value. If so, the network card's service performance is recorded as qualified. Otherwise, the network card's service performance is recorded as unqualified. The accompanying test server is connected to the switch and connected to the semi-virtualized network communication driver (virtio-net) through the second address table. The accompanying test server monitors the network performance data flow and determines whether it is greater than the preset bandwidth value. If so, it records the business performance of the network card as qualified, otherwise it records the business performance of the network card as unqualified.

[0040] That is, if Figure 5 As shown, when the normal installed version network firmware or the abnormal mirror version network firmware is running, when the network card is tested for storage network flow, two types of detection data are included: the controller performance data flow from the host machine to the network card and the network performance data flow of the accompanying test server.

[0041] Among them, the link of the controller performance data flow from the host machine to the network card is: the companion server, switch, the first address table (mac0) of the network card controller, the first physical network port function module (PF1), the storage application (SPDK), the second physical network port function module (PF2), and the paravirtualized block device driver (virtio-blk) of the host machine (Host).

[0042] The link of the network performance data flow of the companion test server is: the companion test server, the switch, the second address table (mac1) of the network card controller, and the paravirtualized network communication driver (virtio-net) of the host (Host).

[0043] Specifically, such as Figure 6 As shown, in this embodiment, when performing a network flow test, the following steps are included: A first address table (mac0) and a second address table (mac1) are set in the network card, and the first address table and the second address table are connected to the accompanying test server through a switch; A third physical network port function module (PF3) is set in the controller of the network card, and a host machine (Host) is set to include a first network card function module (pf0), a second network card function module (pf1), and a third network card function module (pf2), the first network card function module is connected to the second address table, the second network card function module is connected to the first address table, and the third network card function module is connected to the third physical network port function module; The control traffic is sent from the second network card function module to the first address table, passes through the switch to the accompanying test server and is routed back to the second network card function module; Control traffic flows from the first network card function module to the second address table, passes through the switch to the accompanying test server and is routed back to the first network card function module; Control the third network card function module and the third physical network port function module to establish traffic between each other; The accompanying test server monitors the network performance data flow and determines whether it is greater than the preset bandwidth value. If so, it records that the network transmission performance of the network card is qualified; otherwise, it records that the network transmission performance of the network card is unqualified.

[0044] It is understandable that, in response to the normal installation version of the network firmware running in the network card, the service usage performance test of the network card is performed, and the network performance data flow value of the network card is monitored. The network flow test method can be the same as the storage network flow test performed on the network card when the abnormal mirror version of the network firmware is running, including: A first address table (mac0) and a second address table (mac1) are set in the network card, and the first address table and the second address table are connected to the accompanying test server through a switch; A third physical network port function module (PF3) is set in the controller of the network card, and a host machine (Host) is set to include a first network card function module (pf0), a second network card function module (pf1), and a third network card function module (pf2), the first network card function module is connected to the second address table, the second network card function module is connected to the first address table, and the third network card function module is connected to the third physical network port function module; The control traffic is sent from the second network card function module to the first address table, passes through the switch to the accompanying test server and is routed back to the second network card function module; Control traffic flows from the first network card function module to the second address table, passes through the switch to the accompanying test server and is routed back to the first network card function module; Control the third network card function module and the third physical network port function module to establish traffic between each other; The accompanying test server monitors the network performance data flow and determines whether it is greater than the preset bandwidth value. If so, it records the service transmission performance of the network card as qualified; otherwise, it records the service transmission performance of the network card as unqualified.

[0045] That is, if Figure 6As shown, when the normal installed version of the network firmware or the abnormal mirror version of the network firmware is running, when the network card is tested for storage network flow, it includes the data flow of the second network card function module (pf1) of the host (Host), the data flow of the first network card function module (pf0) of the host (Host), the data flow of the third network card function module (pf2) of the host (Host) and the third physical network port function module (PF3) of the network card controller.

[0046] Among them, the link of the data flow of the second network card function module (pf1) of the host (Host) is: the accompanying test server, the switch, the first address table (mac0) of the network card controller, and the second network card function module (pf1) of the host (Host).

[0047] Among them, the link of the data flow of the first network card function module (pf0) of the host (Host) is: the accompanying test server, the switch, the second address table (mac1) of the network card controller, and the first network card function module (pf0) of the host (Host).

[0048] Among them, the link of the data flow between the third network card function module (pf2) of the host (Host) and the third physical network port function module (PF3) of the network card controller is: the third physical network port function module (PF3) of the network card controller and the third network card function module (pf2) of the host (Host).

[0049] In this embodiment, when performing a storage network traffic test on a network card, the following steps are also included: Determine whether the network card has performed a storage network flow test. If so, stop the storage input and output performance test and execute the disk mounting script to delete the disk. If not, execute the storage network flow test and skip executing the disk mounting script.

[0050] In this embodiment, when performing a storage network traffic test on a network card, the following steps are also included: Set the maximum transmission rate thresholds for the first, second, and third network card function modules in the host. When the transmission rate of any of the first, second, or third network card function modules exceeds the maximum transmission rate threshold, the speed is reduced.

[0051] As shown in the figure, the steps of performing a storage network flow test on the network card in this embodiment are as follows: Step 1. SoC environment configuration Modify grub to configure SoC huge pages and IOMMU; In the SoC's grub configuration file (vi / etc / default / grub), add default_hugepagesz=1G hugepagesz=1G hugepages=7 iommu=pt intel_iommu=on to the end of kernel cmdline; Update the grub file: grub2-mkconfig -o / boot / efi / EFI / ctyunos / grub.cfg; Restart the system: reboot.

[0052] Step 2: Configure the host network card IP If you have run a mixed traffic test before, you need to stop fio on the host side first; Run the detach-nvme-disk script to remove the disk. If you have not executed the mount script before, you can skip this step. 1) Hot-swap three network cards on the SoC side and set the mtu to 9000 (-m specifies the mac (address table), which can be configured by yourself); snictool -p -r 0; snictool -p -r 1; snictool -p -a port0 -f 0 -u 9000 -m 00:01:02:03:04:00; snictool -p -a port1 -f 1 -u 9000 -m 00:02:02:03:04:00; snictool -p -a port2 -f 2 -u 9000 -m 00:03:02:03:04:00.

[0053] 2) Configure three elastic network interfaces (ENIs) on the host. The network interface names need to be modified according to the actual situation. You can first use the ifconfig command to view the MAC addresses of the network interfaces and confirm that pf0, pf1, and pf2 correspond to the network interfaces.

The soc and host sides have already set the MTU to 9000 in the steps. When the performance critical point is exceeded, the speed will be reduced and the speed limit will be strictly followed.

[0057] Among them, test step 1: HOST---MAC flow Start the iperf client and iperf server.

[0058] Start the iperf server on the host, soc, and companion test host respectively: iperf -s -w 1M -u -D; The host sends traffic to the companion host. In this example, the traffic rate is limited to 24G.

[0059] iperf -c 12.12.12.13 -i 1 -b 8G -w 1M -t 3000 -u -l 8000 -P 3; iperf -c 13.13.13.13 -i 1 -b 8G -w 1M -t 3000 -u -l 8000 -P 3; The accompanying host sends traffic to the host.

[0062] Start the iperf server on the host and soc respectively: iperf -s -w 1M -u -D; The host sends traffic to the soc, with a speed limit of 45G.

Secondly, the host's pf0 flows to mac1 under the SOC, passes through the switch, and is routed back to pf0 on the accompanying test server. Finally, pf2 and pf3 on the host and soc sides create traffic between each other; the accompanying test server monitors the network performance data flow to determine whether it meets the declared bandwidth value, thereby verifying the stable performance test.
