[0002] PCI-Express (Peripheral Component Interconnect Express, PCIE) is a high-speed serial computer expansion bus standard. PCIE is a high-speed serial point-to-point dual-channel high-bandwidth transmission. Each connected device is allocated its own dedicated channel bandwidth and does not share the bus bandwidth. It mainly supports active power management, error reporting, end-to-end reliable transmission, hot-plugging, and Quality of Service (QoS) functions.

[0003] In a PCIe link, the port bandwidth of the sending and receiving devices is the same, and a PCIe link can only connect one sending device and one receiving device. As server performance requirements continue to increase, more and more devices are being mounted on the PCIe bus on the motherboard. To meet the ever-increasing performance requirements of servers, PCIe links can be expanded using peripheral device switches (PCIe switches) to connect multiple terminal devices. However, the number of terminal devices on the downlink port of a new link cannot be expanded indefinitely.

[0044] 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.

[0045] One of the core concepts of this invention is that by acquiring the uplink port slot information and saving it to a storage module, a terminal device is selected based on the uplink port slot information, the performance of the terminal device is detected, and performance data of the terminal device is generated. A judgment module determines whether the performance data meets preset conditions. When the performance data meets the preset conditions, an alarm module provides a prompt, and the next terminal device is selected for detection. After multiple terminal devices have been detected, the convergence ratio of the peripheral device switch is determined, a test report is generated, and the test report is displayed on a display module. This enables automatic testing through a detection device, making peripheral device switch bottleneck detection simpler and faster. The test results can be directly displayed through the display module, effectively improving the testing efficiency of peripheral device switch bottlenecks. At the same time, it allows people to understand the various data more clearly, facilitating testing and use.

[0046] Reference Figure 1 This document illustrates a flowchart of an embodiment of a method for detecting peripheral device switches according to the present invention, comprising: a processor, a detection device, a peripheral device switch, and terminal devices; the peripheral device switch has multiple ports, including one uplink port and at least two downlink ports, the uplink port being connected to the processor via a root component, and the detection device being connected to the downlink ports of the peripheral device switch and multiple terminal devices respectively; the method is applied to the detection device, which includes: a storage module, a judgment module, a display module, and an alarm module; specifically, it may include the following steps:

[0047] Step 101: Obtain the slot information of the uplink port and save the slot information of the uplink port to the storage module;

[0048] PCIe comes in various sizes, from PCIe x1 to PCIe x32, to meet the needs of both low-speed and high-speed devices for a certain period. In a single PCIe link, the port bandwidth of the sending and receiving devices is the same, and a single PCIe link can only connect one sending and one receiving device. To meet the ever-increasing performance requirements of servers, PCIe links can be extended using peripheral switches to connect multiple terminal devices. Peripheral switches provide expansion or aggregation capabilities, allowing more devices to connect to a single PCIe port. A peripheral switch acts as a packet router, identifying the path a given packet should take based on its address or other routing information. It is a PCIe-to-PCIe bridge.

[0049] Reference Figure 2 This diagram illustrates a PCIe link structure with an expanded peripheral device switch. The peripheral device switch has multiple ports, including one uplink port and at least two downlink ports. There is only one root complex (RC) in the link, used to connect the processor (CPU, Central Processing Unit) to the uplink port of the peripheral device switch. The processor allocates resources such as memory through the root complex. One processor can connect to multiple peripheral device switches through the root complex. The uplink ports of multiple peripheral device switches can include various slot information. A detection device can be placed between the peripheral device switch and the terminal device, connecting to both the downlink port of the peripheral device switch and the terminal device. When detecting the peripheral device switch, the slot information of the uplink port of the peripheral device switch must first be obtained. The slot information of the downlink port, FW (Firewall), Driver, Slot ID, etc., can also be obtained, and the obtained peripheral device switch information is saved to a storage module. In one example, the slot information of the uplink port of the peripheral device switch can be x16, PCIe 4.0. It will be understood by those skilled in the art that the above slot information is merely an example and the present invention does not limit it.

[0050] Step 102: Select the terminal device based on the slot information of the uplink port;

[0051] In one example, if the uplink port slot information of the peripheral device switch is x16, PCIe 4.0, then its throughput (available bandwidth) is approximately 256Gb / s. A terminal device with the same uplink port bandwidth as the peripheral device switch can be selected for testing. In this case, a 100G GEN4 (fourth-generation solid-state drive) network card is initially determined for testing. Those skilled in the art will understand that the selected slot information and terminal device described above are merely examples, and this invention does not limit the scope of the invention.

[0052] Step 103: Detect the performance of the terminal device and generate performance data of the terminal device;

[0053] When the number of terminal devices is expanded to a certain extent through the peripheral device switch, the peripheral device switch will create a performance bottleneck, which will affect the performance of the terminal devices. When the performance bottleneck of the peripheral device switch is reached, the performance of the terminal devices may not meet the test requirements. Therefore, after initially determining the terminal devices, it is necessary to test the performance of the terminal devices through a testing device to generate performance data of the terminal devices.

[0054] Step 104: The judgment module determines whether the performance data meets the preset conditions. When the performance data meets the preset conditions, the alarm module provides a prompt and selects the next terminal device for testing.

[0055] After generating the performance data of the terminal device, the judgment module can determine whether the performance data meets the preset conditions. When the performance data meets the preset conditions, it means that the performance bottleneck of the peripheral device switch is affecting the performance of the terminal device. The alarm module of the peripheral device switch will issue a prompt, and then the next terminal device will be selected for testing.

[0056] Step 105: After the multiple terminal devices have been detected, determine the convergence ratio of the peripheral device switch, generate a detection report, and display the detection report on the display module.

[0057] After multiple terminal devices have completed their testing, the slot information of the uplink port of the peripheral device switch and the information of the terminal devices are obtained to determine the convergence ratio of the peripheral device switch. Based on the obtained peripheral device switch information and terminal device information, a test report is generated and displayed on the display module.

[0058] This invention acquires uplink port slot information and saves it to a storage module. Based on this information, it selects a terminal device, tests its performance, and generates performance data. A judgment module determines whether the performance data meets preset conditions. When the data meets these conditions, an alarm module alerts the user, and the next terminal device is selected for testing. After multiple terminal devices have been tested, the peripheral device switch convergence ratio is determined, a test report is generated, and displayed on a display module. This enables automated testing via a detection device, simplifying peripheral device switch bottleneck detection and allowing for rapid identification of bottlenecks. The display module provides direct access to test results, effectively improving the efficiency of peripheral device switch bottleneck testing. Furthermore, it allows users to clearly understand the various data points, facilitating testing and use.

[0059] Reference Figure 3 This document illustrates a flowchart of another embodiment of a method for detecting peripheral device switches according to the present invention, comprising: a processor, a detection device, a peripheral device switch, and terminal devices; the peripheral device switch has multiple ports, including one uplink port and at least two downlink ports, the uplink port being connected to the processor via a root component, and the detection device being connected to the downlink ports of the peripheral device switch and multiple terminal devices respectively; the method is applied to the detection device, which includes: a storage module, a judgment module, a display module, and an alarm module; specifically, it may include the following steps:

[0060] Step 301: According to preset rules, connect the port of the peripheral device switch via cable to put the peripheral device switch into test state.

[0061] Before testing the peripheral device switch, according to the design requirements of the server to which the processor belongs, the uplink port is connected to the processor, the downlink port is connected to the testing device, and the testing device is connected to the terminal device to form a link, so that the peripheral device switch enters the test state.

[0062] Step 302: Obtain the slot information of the uplink port and save the slot information of the uplink port to the storage module;

[0063] When testing a peripheral device switch, it is necessary to first obtain the slot information of the switch's uplink port. It is also possible to obtain the slot information, FW, Driver, Slot ID, etc., of the downlink port, and save the obtained peripheral device switch information to the storage module. In one example, the slot information of the peripheral device switch's uplink port can be x16, PCIe 4.0. Those skilled in the art will understand that the above slot information is merely an example, and the present invention does not limit its scope.

[0064] Step 303: The processor allocates resources based on the slot information of the uplink port of the peripheral device switch;

[0065] The processor is the core of a computer's computation and control. Its main functions are interpreting computer instructions and processing data in computer software. Computer memory temporarily stores the processor's computational data, providing read and write capabilities. Each processor has a fixed number of PCIe lanes; some processors support 32, while others support 48. Processors can connect to peripheral device switches via a root component, which allocates resources based on the peripheral device switch's uplink slot information.

[0066] Step 304: Determine the terminal devices according to the order of resource usage by the terminal devices.

[0067] When the uplink bandwidth of the peripheral device switch is the same as that of the terminal device, the terminal device will occupy the most resources. Therefore, a terminal device with the same uplink bandwidth as the peripheral device switch can be selected for testing.

[0068] In one example, if the uplink port slot information of the peripheral device switch is x16, PCIe 4.0, then its throughput (available bandwidth) is approximately 256Gb / s. In this case, it is initially determined that a 100G GEN4 network card will be used for testing. Those skilled in the art will understand that the slot information and terminal device selected above are merely examples, and this invention does not limit the scope of the invention.

[0069] Step 305: Detect the performance of the terminal device and generate performance data of the terminal device;

[0070] When the number of terminal devices is expanded to a certain extent through a peripheral device switch, the peripheral device switch will create a performance bottleneck, which will affect the performance of the terminal devices. When the performance bottleneck of the peripheral device switch is reached, it may affect the performance of the terminal devices. Therefore, after initially determining the terminal devices, it is necessary to use a testing device to test the performance of the terminal devices and generate performance data of the terminal devices.

[0071] In an optional embodiment of the present invention, the detection device includes multiple testing tools, and the multiple terminal devices include multiple device types. Step 305 includes:

[0072] Sub-step S11: Determine the device type of the terminal device;

[0073] Terminal devices can be of different types, such as network interface cards (NICs), GPUs (Graphics Processing Units), and NVMe (Non-Volatile Memory Express) hard drives. Therefore, the device type of the terminal device must be determined during testing.

[0074] Sub-step S12: Select a testing tool based on the device type of the terminal device;

[0075] Those skilled in the art will understand that different types of terminal devices require different testing tools. When the terminal device is a network card, netperf (a network performance measurement tool) is used to test its performance; when the terminal device is a GPU, nvqual (a performance testing tool) is used; and when the terminal device is an NVMe hard drive, fio (a flexible I / O tester) is used. Once the type of terminal device is determined during testing, the appropriate testing tool can be selected accordingly.

[0076] Sub-step S13: The performance of the terminal device is detected by the testing tool, and performance data corresponding to the device type of the terminal device is generated.

[0077] Those skilled in the art will understand that the performance data required for testing differs for different types of terminal devices. When the terminal device is a network card, netperf detects the performance data of the terminal device as bandwidth. When the terminal device is a GPU, nvqual detects the performance data of the terminal device as P2P (Peer to Peer) bandwidth. When the terminal device is an NVMe hard drive, fio detects the performance data of the terminal device as 4K random read, 4K random write, etc.

[0078] In an optional embodiment of the present invention, the method for determining whether the performance data meets preset conditions includes:

[0079] The judgment module determines whether the performance data exceeds a preset percentage of the standard performance data of the terminal device.

[0080] When the performance data is lower than a preset percentage of the standard performance data of the terminal device, it is determined that the performance data meets the preset conditions.

[0081] In this embodiment, the test performance data detected by the testing tool can be compared with a preset percentage of the standard performance data of the terminal device. In one example, it can be compared with 90% of the standard performance data of the terminal device. If the terminal device is a 100G GEN4 network card and the test performance data detected by the testing tool is lower than 90G, the judgment module can determine that the performance data of the terminal device is lower than 90% of the standard performance data, and determine that the performance data meets the preset condition. Those skilled in the art will understand that the terminal device selected above and the value of the preset percentage are only examples, and the present invention does not limit them.

[0082] Step 306: When the judgment module determines that the performance data exceeds a preset percentage of the standard performance data of the terminal device, it determines that the performance data does not meet the preset conditions and replaces the current terminal device.

[0083] When the judgment module determines that the performance data exceeds the preset percentage of the standard performance data of the terminal device, it determines that the performance data does not meet the preset conditions, indicating that the peripheral device switch performance bottleneck has not been reached and the current terminal device needs to be replaced.

[0084] In one example, if the terminal device is a 100G Gen4 network card and the test performance data detected by the testing tool exceeds 90G, the judgment module can determine that the terminal device's performance data is below 90% of the standard performance data, and has not reached the performance bottleneck of the peripheral device switch. A higher-level terminal device, such as a single-port 200G Gen4 network card, can then be replaced. Those skilled in the art will understand that the terminal device selected above, and the preset percentage values, are merely examples, and this invention does not impose limitations.

[0085] Step 307: When the judgment module determines that the performance data is lower than the preset percentage of the standard performance data of the terminal device, it determines that the performance data meets the preset conditions, the alarm module provides a prompt, and the next terminal device is selected for testing.

[0086] When the judgment module determines that the performance data is lower than the preset percentage of the standard performance data of the terminal device, it determines that the performance data meets the preset conditions, indicating that the peripheral device switch performance bottleneck has been reached and the test requirements are met. The alarm module will then issue a prompt and select the next terminal device for testing.

[0087] In one example, if the terminal device is a 100G Gen4 network card and the test performance data detected by the testing tool exceeds 90G, the judgment module can determine that the terminal device's performance data is below 90% of the standard performance data, and has not reached the peripheral device switch performance bottleneck. A higher-level terminal device can be replaced, such as a single-port 200G Gen4 network card. If the peripheral device switch performance bottleneck is still not reached after replacing the terminal device, a dual-port 200G Gen4 network card can be replaced until the peripheral device switch performance bottleneck is reached. At this point, the alarm module will issue a prompt, and the next terminal device can be tested. Those skilled in the art will understand that the terminal devices selected above, and the preset percentage values, are merely examples, and this invention does not limit the scope of the invention.

[0088] Step 308: Based on the slot information of the uplink port and the device types of the multiple terminal devices, determine the convergence ratio of the peripheral device switch;

[0089] After all the terminal devices connected to the peripheral device switch have completed the detection, the slot information of the downstream port of the peripheral device switch can be determined by the device type of the multiple terminal devices. Based on the slot information of the upstream port and the slot information of the downstream port of the peripheral device switch, the convergence ratio of the peripheral device switch can be determined.

[0090] Step 309: Based on the convergence ratio, the performance data, and the slot information of the uplink and downlink ports of the peripheral device switch, generate a test report and display the test report on the display module.

[0091] After obtaining the convergence ratio of the peripheral device switch, a test report is generated based on the convergence ratio, performance data, and the slot information of the uplink and downlink ports of the peripheral device switch. The test report is then displayed on the display module, making it easier for testers to understand the various data more clearly.

[0092] In an optional embodiment of the present invention, the terminal device is a host channel adapter (HCA) card.

[0093] HCA (Host Channel Adapter) cards are primarily used to achieve high-performance computing with infinite bandwidth. RDMA (Remote Direct Memory Access) is a new direct memory access technology that allows a computer to directly access the memory of other computers without processor processing. RDMA is essentially a high-speed remote memory access technology with a fully optimized intelligent network card and software architecture. It achieves its high-performance remote direct data access goal by embedding the RDMA protocol on the hardware (i.e., the HCA card) and supporting both zero-copy and kernel bypass methods. HCA cards do not require CPU involvement—applications can access remote host memory without consuming any CPU resources on the remote host. Therefore, using HCA cards reduces the impact of CPU performance during testing, allowing for more accurate testing of peripheral device switch bottleneck performance.

[0094] This invention embodiment acquires uplink port slot information and saves it to a storage module. The processor allocates resources based on the uplink port slot information of the peripheral device switch. It determines the terminal device according to the order of resource usage by the terminal devices, detects the terminal device's performance, and generates performance data. When the judgment module determines that the performance data exceeds a preset percentage of the terminal device's standard performance data, it determines that the performance data does not meet the preset conditions and replaces the current terminal device. When the judgment module determines that the performance data is lower than a preset percentage of the terminal device's standard performance data, it determines that the performance data meets the preset conditions, the alarm module provides a prompt, and the next device is selected. The terminal equipment is tested. Based on the uplink port slot information and the device types of multiple terminal devices, the convergence ratio of the peripheral device switch is determined. Based on the convergence ratio, performance data, and the uplink and downlink port slot information of the peripheral device switch, a test report is generated and displayed on the display module. This enables automatic testing through the testing device, making peripheral device switch bottleneck detection simpler and faster. The test results can be directly displayed through the display module, effectively improving the testing efficiency of peripheral device switch bottlenecks. At the same time, it allows people to understand various data more clearly, facilitating testing and use.

[0095] To enable those skilled in the art to better understand the present invention, reference is made to... Figure 4 The flowchart illustrates an embodiment of a method for detecting peripheral device switches according to the present invention:

[0096] Step 401, peripheral device switch information collection;

[0097] It can collect information such as the slot information of the uplink port, the slot information of the downlink port, FW, Driver, and Slot ID of the peripheral device switch.

[0098] Step 402: Obtain the slot information of the uplink port of the peripheral device switch;

[0099] Obtain the slot information of the uplink port of the peripheral device switch from the collected peripheral device switch information.

[0100] Step 403: Select a terminal device based on the slot information of the uplink port;

[0101] You can select a terminal device with the same uplink bandwidth as the peripheral device switch for testing.

[0102] Step 404: Detect the performance of the terminal device and generate performance data of the terminal device;

[0103] After initially identifying the terminal equipment, its performance needs to be tested using a testing device to generate performance data.

[0104] Step 405: Determine whether the performance data of the terminal device meets the preset conditions. If yes, proceed to step 406; otherwise, proceed to step 407 and return to step 404.

[0105] Step 406: The peripheral device switch performance bottleneck is reached, proceed to step 408.

[0106] Step 407: Replace the current terminal device.

[0107] When the performance data meets the preset conditions, it indicates that the peripheral device switch has reached its performance bottleneck and the test requirements are met.

[0108] When the performance data does not meet the preset conditions, it means that the peripheral device switch performance bottleneck has not been reached, and the current terminal device needs to be replaced and retested.

[0109] Step 408: Determine whether all terminal devices have completed the detection. If not, proceed to step 409 and return to step 404. If yes, end the detection.

[0110] Step 409: Select the next terminal device.

The storage module 501 stores the slot information of the uplink port of the peripheral device switch. The judgment module 502 determines whether the performance data of the terminal device meets preset conditions.
