Description

Technical Field

[0001] The present invention relates to the field of computer technology, and in particular to a bandwidth setting method, device, computer equipment and storage medium. Background Art

[0002] With the rapid development of artificial intelligence and big data analysis, the demand for high-performance computing and graphics processing is also increasing. Traditional computer systems often cannot meet these needs, so high-performance computing servers based on graphics processing units (GPUs) have emerged. High-performance servers usually need to integrate multiple peripheral component interconnect express (PCIE) devices, such as high-performance graphics cards, high-speed solid-state drives, professional network cards, and field-programmable gate array (FPGA) acceleration cards to achieve different functions. Different PCIE devices require different working bandwidths.

[0003] In the related art, a switch (PCIe Switch) is an important PCIE expansion device that can allocate bandwidth for each PCIE device. PCIe Switch will allocate default bandwidth to each PCIE device according to the current server model, that is, a certain amount of bandwidth resources will be fixedly allocated to each PCIE device when the system starts. However, the bandwidth requirements of PCIE devices may vary greatly in different working scenarios. The traditional static bandwidth allocation method cannot match the appropriate bandwidth resources for the device based on different working scenarios, resulting in a waste of bandwidth resources or insufficient bandwidth for some key devices, affecting the overall performance of the system. Summary of the invention

[0004] In view of this, the present invention provides a bandwidth setting method to solve the problem that it is impossible to match appropriate bandwidth resources for devices based on different working scenarios, resulting in bandwidth resource waste or insufficient bandwidth for certain key devices.

[0005] In a first aspect, the present invention provides a bandwidth setting method, the method comprising: obtaining bandwidth association information and current working status information of each device in at least one device associated with a host; obtaining the priority of configuring bandwidth for each device in at least one device; determining each target bandwidth parameter value corresponding to each device based on the priority, bandwidth association information and current working status information; recording each target bandwidth parameter value in a register corresponding to each device, so that a switch reads from the register and sets at least one bandwidth of at least one device based on each target bandwidth parameter value.

[0006] The method provided in this aspect can obtain bandwidth association information and current working status information of each device in at least one device associated with the host, as well as the priority of each device to configure the bandwidth; based on the priority, bandwidth association information and current working status information, determine each target bandwidth parameter value corresponding to each device to set at least one bandwidth of at least one device.

[0007] Since the target bandwidth parameter value is determined based on the bandwidth association information, current working status information and priority of each device, and the determined target bandwidth parameter value can be recorded in the corresponding register, the switch can set the bandwidth of each device based on the target bandwidth parameter value in the register. Compared with the method in the related art where the switch directly sets the default bandwidth for each device, the present invention can match the appropriate bandwidth parameter value for each device based on different working scenarios and the bandwidth association information of each device, thereby avoiding the waste of bandwidth resources or the problem of insufficient bandwidth of certain key devices, and improving the utilization rate of bandwidth resources.

[0008] In an optional implementation, the bandwidth association information includes a manufacturer identification code and a device identification code, and obtaining the priority of configuring the bandwidth for each device in at least one device includes: obtaining a service weight value corresponding to each device, the service weight value is used to indicate the criticality of each device to the service; determining the device type of each device based on the manufacturer identification code and the device identification code; determining the priority corresponding to each device based on the device type and the service weight value.

[0009] Based on the above method, the priority of each device can be determined based on the criticality of each device to the business and the device type, so as to facilitate the subsequent allocation of bandwidth resources based on priority and ensure that the devices corresponding to the key business can obtain sufficient bandwidth resources.

[0010] In an optional implementation, the bandwidth association information includes a maximum bandwidth parameter value supported by each device, and the current working status information includes a current working mode and current operation information of each device; based on the priority, the bandwidth association information and the current working status information, each target bandwidth parameter value corresponding to each device is determined, including: determining a first bandwidth parameter value corresponding to each device according to the current working mode, the first bandwidth parameter value being a minimum bandwidth parameter value required for the current working mode; determining a second bandwidth parameter value corresponding to each device according to the current working status information; determining each bandwidth parameter value corresponding to each device based on the first bandwidth parameter value, the second bandwidth parameter value and the maximum bandwidth parameter value; adjusting each bandwidth parameter value based on the priority, and determining each target bandwidth parameter value corresponding to each device.

[0011] Based on the above method, by determining the first bandwidth parameter value, that is, the minimum bandwidth required for the current working mode, it can be ensured that each device can obtain sufficient bandwidth to maintain basic operations under any circumstances. The second bandwidth parameter value determined based on the current working status information, that is, the bandwidth parameter value consistent with the current actual working status can be determined in combination with the current actual working status of each device; and the maximum bandwidth parameter value can limit the maximum bandwidth resources that can be allocated to each device, avoiding the situation where too many resources are allocated to each device that the device does not support. Adjust each bandwidth parameter value based on priority to avoid allocating too much bandwidth to low-priority or inactive devices, thereby improving overall bandwidth utilization and ensuring that high-priority devices always have sufficient bandwidth to ensure the stability and high performance of key services.

[0012] In an optional implementation, the current operation information includes the bandwidth utilization rate and bandwidth power consumption value of each device; based on the current working status information, the second bandwidth parameter value corresponding to each device is determined, including: obtaining the available bandwidth resources of the host at the current moment; determining the second bandwidth parameter value corresponding to each device according to the available bandwidth resources and the bandwidth utilization rate, or determining the second bandwidth parameter value corresponding to each device according to the available bandwidth resources and the bandwidth power consumption value.

[0013] Based on the above method, the real-time demand of each device is determined according to the bandwidth usage rate or bandwidth power consumption value of each device, and real-time adjustment is made according to the available bandwidth resources of the host at the current moment to ensure that the second bandwidth parameter value corresponding to each device matches the actual demand.

[0014] In an optional implementation, a second bandwidth parameter value corresponding to each device is determined based on available bandwidth resources and bandwidth usage, including: determining a bandwidth allocation ratio for each device based on a bandwidth power consumption value of each device in at least one device; and determining a second bandwidth parameter value corresponding to each device based on the bandwidth allocation ratio and available bandwidth resources.

[0015] Based on the above method, the bandwidth allocation ratio of each device can be accurately determined through the bandwidth usage rate of each device, so that bandwidth resources can be accurately allocated to each device to ensure that each device obtains the most appropriate bandwidth.

[0016] In an optional implementation, at least one device includes a first device; based on the first bandwidth parameter value, the second bandwidth parameter value and the maximum bandwidth parameter value, determining each target bandwidth parameter value corresponding to each device includes: determining the bandwidth parameter value corresponding to the first device based on the first bandwidth parameter value, the second bandwidth parameter value and the maximum bandwidth parameter value of the first device; wherein, based on the first bandwidth parameter value, the second bandwidth parameter value and the maximum bandwidth parameter value of the first device, determining the bandwidth parameter value corresponding to the first device includes: comparing the first bandwidth parameter value and the second bandwidth parameter value of the first device; if the second bandwidth parameter value of the first device is greater than or equal to the first bandwidth parameter value, and the second bandwidth parameter value of the first device is less than or equal to the maximum bandwidth parameter value, determining the bandwidth parameter value corresponding to the first device is the second bandwidth parameter value; if the second bandwidth parameter value of the first device is greater than or equal to the first bandwidth parameter value, and the second bandwidth parameter value of the first device is greater than or equal to the maximum bandwidth parameter value, determining the bandwidth parameter value corresponding to the first device is the maximum bandwidth parameter value; if the second bandwidth parameter value of the first device is less than the first bandwidth parameter value, and the first bandwidth parameter value of the first device is less than the maximum bandwidth parameter value, determining the bandwidth parameter value corresponding to the first device is the first bandwidth parameter value.

[0017] Based on the above method, the first bandwidth parameter value and the second bandwidth parameter value can be compared, and based on the maximum bandwidth parameter value, each target bandwidth parameter value corresponding to the first device can be accurately determined.

[0018] In an optional implementation, after the switch sets at least one bandwidth of at least one device, the average throughput and average delay of each device in the at least one device within a preset time period are obtained; it is detected whether the average throughput and average delay of each device meet preset conditions, and the preset conditions are associated with the throughput and delay required by each device; if not, it is determined that the average actual bandwidth does not meet the business requirements of supporting each device, and each target bandwidth parameter value is adjusted.

[0019] Based on the above method, by monitoring the average throughput and average latency of each device, it is possible to determine whether the average actual bandwidth of each device meets the business needs of each device, thereby avoiding service interruption or user experience degradation caused by insufficient bandwidth resources of each device. When it is detected that the bandwidth of some devices fails to meet the preset conditions, the target bandwidth parameter value can be adjusted in time.

[0020] In a second aspect, the present invention provides a bandwidth setting device, which includes: an acquisition module, used to obtain bandwidth association information and current working status information of each device in at least one device associated with a host; the acquisition module is also used to obtain the priority of configuring the bandwidth of each device in at least one device; a processing module is used to determine each target bandwidth parameter value corresponding to each device based on the priority, bandwidth association information and current working status information; the processing module is also used to record each target bandwidth parameter value in a register corresponding to each device, so that the switch reads from the register and sets at least one bandwidth of at least one device based on each target bandwidth parameter value.

[0021] In a third aspect, the present invention provides a computer device, comprising: a memory and a processor, the memory and the processor are communicatively connected to each other, the memory stores computer instructions, and the processor executes the bandwidth setting method of the first aspect or any corresponding embodiment thereof by executing the computer instructions.

[0022] In a fourth aspect, the present invention provides a computer-readable storage medium having computer instructions stored thereon, the computer instructions being used to enable a computer to execute the bandwidth setting method of the first aspect or any corresponding embodiment thereof.

[0023] In a fifth aspect, the present invention provides a computer program product, including computer instructions, where the computer instructions are used to enable a computer to execute the bandwidth setting method of the first aspect or any corresponding embodiment thereof.

[0030] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0031] The embodiment of the present invention is applied in a server, in a scenario where a PCIe Switch allocates bandwidth for each PCIE device.

[0032] High-performance servers are usually equipped with a variety of PCIE devices, and different PCIE devices require different working bandwidths. Based on the use of business, the same PCIE device may also have different bandwidth working modes. The traditional static bandwidth allocation method cannot match the appropriate bandwidth resources for the device based on different working scenarios, resulting in bandwidth resource waste or insufficient bandwidth for some key devices, affecting the overall performance of the system.

[0033] In order to solve the above technical problems, an embodiment of the present invention provides a bandwidth setting method, which determines each target bandwidth parameter value corresponding to each device through the priority, bandwidth association information and current working status information of each device, so as to achieve the effect of matching the appropriate bandwidth parameter value for each device in different working scenarios.

[0034] Below Figure 1 Taking the bandwidth setting system 100 of the device shown as an example, the method provided in the embodiment of the present application is described. Figure 1 It is only a schematic diagram and does not constitute a limitation on the applicable scenarios of the technical solution provided in this application.

[0035] like Figure 1 As shown, Figure 1 4 is a topological diagram of a bandwidth setting system according to an embodiment of the present invention. Figure 1 In the embodiment, the bandwidth setting system 100 may include a baseboard management controller 101 , a register 102 , a switch 103 , a first device 104 , and a second device 105 .

[0036] The baseboard management controller 101 in the embodiment of the present invention may be a controller (Baseboard Management Controller, BMC) integrated in a server, a network device, or other computer systems.

[0037] The register 102 in the embodiment of the present invention may be any register. For example, the register 102 may be a register in a complex programmable logic device (CPLD), a general register, a special register, a base address register, a floating point register, or a status register. The register 102 is used to store the bandwidth parameter value of each device.

[0038] The switch 103 in the embodiment of the present invention is also called a PCIe Switch. As an important PCIe expansion device, the PCIe Switch can effectively solve the problem of limited number of PCIe slots on the motherboard. Multiple PCIe devices are connected to the host system through one or more PCIe Switches.

[0039] The first device 104 or the second device 105 in the embodiment of the present invention may be any PCIE device. For example, the first device 104 may be a network card, and the second device 105 may be a hard disk.

[0040] Figure 1 The bandwidth setting system 100 shown is only used as an example and is not used to limit the technical solution of the present application. Those skilled in the art should understand that in the specific implementation process, the bandwidth setting system 100 may also include other devices without limitation.

[0041] According to an embodiment of the present invention, a bandwidth setting method embodiment is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0042] In this embodiment, a bandwidth setting method is provided, which can be used in the above-mentioned baseboard management controller. Figure 2 is a flow chart of a bandwidth setting method according to an embodiment of the present invention. Figure 2 As shown, the process includes the following steps:

[0043] S201: Obtain bandwidth association information and current working status information of each device in at least one device associated with the host.

[0044] The bandwidth-related information includes a manufacturer identification code, a device identification code, and a maximum bandwidth parameter value supported by each device.

[0045] The current working status information includes the current working mode and current operation information of each device. The current operation information includes the bandwidth usage rate and bandwidth power consumption value of each device.

[0046] Exemplarily, the BMC uses a built-in PCIe scanning function or a PCIe bus enumeration tool to scan the PCIe bus on the host, and obtains bandwidth association information and current working status information of each device in at least one device associated with the host.

[0047] Optionally, the BMC may also obtain a bus number, a device number, and a function number of each device in the at least one device to determine a physical location of each device.

[0048] S202: Obtain a priority of bandwidth configuration for each device in at least one device.

[0049] In some optional implementations, the BMC obtains a service weight value corresponding to each device; determines the device type of each device based on the manufacturer identification code and the device identification code; and determines the priority corresponding to each device based on the device type and the service weight value.

[0050] The service weight value is used to indicate the criticality of each device to the service. Optionally, the service weight value is associated with the degree of impact of each device on the overall performance of the system. For example, for a server system, the service weight values ​​of network communication and storage devices are high, and the service weight values ​​of other devices are low. For a graphics processing system, the service weight values ​​corresponding to graphics card devices are high, and the service weight values ​​of other devices are low.

[0051] The device type can be a high-performance graphics processing type (e.g., graphics card), a network communication type (e.g., 10 Gigabit network card), a storage type (e.g., high-speed solid-state hard disk), or a computing acceleration type (e.g., Field-Programmable Gate Array (FPGA)). Different device types have different priorities for configuring bandwidth. For example, the priority of configuring bandwidth for a high-performance graphics processing device is higher than the priority of configuring bandwidth for a computing acceleration device.

[0052] In one example, taking at least one device including a first device and a second device as an example, if the first device and the second device are of the same device type, the BMC compares the first business weight value of the first device and the second business weight value of the second device; if the first business weight value is higher than the second business weight value, it is determined that the priority of the first device is higher than the priority of the second device.

[0053] In another example, taking at least one device including a first device and a second device as an example, if the service weight values ​​of the first device and the second device are consistent, the BMC determines the priority of the first device and the second device according to the first device type of the first device and the second device type of the second device.

[0054] In some optional embodiments, the baseboard management controller determines a first priority value corresponding to the device type of each device based on the device type of each device and a preset correspondence; obtains a weight coefficient corresponding to the business weight value of each device; calculates the product between the business weight value of each device and the weight coefficient to obtain a second priority value corresponding to the business weight value of each device; calculates the sum of the first priority value and the second priority value to obtain a total priority value for each device, and determines the priority of each device based on the total priority value of each device.

[0055] The preset corresponding relationship is the corresponding relationship between the device type and the first priority value.

[0056] It is understandable that the larger the total priority value, the higher the priority of the device. BMC calculates the total priority value of each device by combining the device type, the criticality of each device to the business, and the impact on the overall system performance, so that BMC can determine the allocation of bandwidth resources according to the priority of each device to ensure that the devices corresponding to key businesses can obtain sufficient bandwidth resources.

[0057] S203: Determine each target bandwidth parameter value corresponding to each device based on the priority, bandwidth association information and current working status information.

[0058] The target bandwidth parameter value may be a link speed value and a number of virtual channels of a port of the switch connected to the PCIE device.

[0059] In some optional embodiments, the baseboard management controller determines a first bandwidth parameter value corresponding to each device according to the current working mode; determines a second bandwidth parameter value corresponding to each device according to the current working status information; determines each bandwidth parameter value corresponding to each device based on the first bandwidth parameter value, the second bandwidth parameter value and the maximum bandwidth parameter value; and adjusts each bandwidth parameter value based on a priority to determine each target bandwidth parameter value corresponding to each device.

[0060] The first bandwidth parameter value is the minimum bandwidth parameter value required for the current working mode. The current working mode is associated with the performance of each device. For example, for a storage device, the current working mode may be an idle mode, a data read / write mode, or an initialization mode. The first bandwidth parameter value corresponding to the data read / write mode is greater than the first bandwidth parameter value corresponding to the initialization mode.

[0061] In some optional embodiments, the baseboard management controller obtains the available bandwidth resources of the host at the current moment; determines the second bandwidth parameter value corresponding to each device based on the available bandwidth resources and the bandwidth utilization rate, or determines the second bandwidth parameter value corresponding to each device based on the available bandwidth resources and the bandwidth power consumption value.

[0062] In one example, the baseboard management controller determines the bandwidth allocation ratio of each device according to the bandwidth power consumption value of each device in at least one device; and determines the second bandwidth parameter value corresponding to each device according to the bandwidth allocation ratio and the available bandwidth resources.

[0063] For example, taking at least one device including a first device and a second device, and the ratio of the first bandwidth power consumption value of the first device to the second bandwidth power consumption value of the second device is 2:3, the baseboard management controller determines that the bandwidth allocation ratio of the first device to the second device is 2:3 according to the first bandwidth power consumption value of the first device and the second bandwidth power consumption value of the second device; and determines the second bandwidth parameter value corresponding to each device according to the ratio of 2:3 for the available bandwidth resources.

[0064] In one example, the baseboard management controller determines the bandwidth allocation ratio of each device according to the bandwidth usage rate of each device in at least one device; and determines the second bandwidth parameter value corresponding to each device according to the bandwidth allocation ratio and the available bandwidth resources.

[0065] In one example, for a network card device, the BMC can obtain the current flow of the network card port at the current moment and the maximum flow of the network card port in a preset time period, and calculate the bandwidth usage rate of the network card device.

[0066] It is understandable that the preset time period can be set according to actual needs without limitation.

[0067] In some optional embodiments, the baseboard management controller compares the first bandwidth parameter value and the second bandwidth parameter value of the first device; if the second bandwidth parameter value of the first device is greater than or equal to the first bandwidth parameter value, and the second bandwidth parameter value of the first device is less than or equal to the maximum bandwidth parameter value, the bandwidth parameter value corresponding to the first device is determined to be the second bandwidth parameter value; if the second bandwidth parameter value of the first device is less than the first bandwidth parameter value, and the second bandwidth parameter value of the first device is greater than or equal to the maximum bandwidth parameter value, the bandwidth parameter value corresponding to the first device is determined to be the maximum bandwidth parameter value; if the second bandwidth parameter value of the first device is less than the first bandwidth parameter value, and the first bandwidth parameter value of the first device is less than the maximum bandwidth parameter value, the bandwidth parameter value corresponding to the first device is determined to be the first bandwidth parameter value.

[0068] It can be understood that each bandwidth parameter value of each device is greater than or equal to the first bandwidth parameter value, and less than or equal to the maximum bandwidth parameter value.

[0069] In one example, the baseboard management controller adjusts each bandwidth parameter value based on the priority and determines each target bandwidth parameter value corresponding to each device.

[0070] It is understandable that, since the working state of each device in at least one device changes dynamically, and the service tasks performed by each device at different times are also different, that is, the priorities of different devices also change dynamically. Therefore, in the case of limited bandwidth resources, for high-priority devices, the BMC can give priority to allocating sufficient bandwidth resources to ensure the execution of key services. For example, during the data backup period of the storage device, the BMC can give priority to allocating sufficient bandwidth resources to the storage device to ensure the success of the data backup.

[0071] S204: Record each target bandwidth parameter value in a register corresponding to each device, so that the switch reads from the register and sets at least one bandwidth of at least one device based on each target bandwidth parameter value.

[0072] Exemplarily, the BMC obtains a register mapping document of the CPLD to determine a register address and a function description related to PCIe Switch control; based on the register address and the function description, determines a register address corresponding to a bandwidth of a PCIe Switch port to which each device is connected; and writes a register value corresponding to each target bandwidth parameter value into a register address corresponding to each determined device through a communication interface with the CPLD, so as to record each target bandwidth parameter value in a register corresponding to each device.

[0073] It is understandable that in the process of the BMC writing each target bandwidth parameter value into the register address corresponding to each determined device, a data check and error handling mechanism (eg, a cyclic redundancy check mechanism) may be used to prevent a write error from causing a system failure.

[0074] In one example, after the BMC records each target bandwidth parameter value in a register corresponding to each device, the CPLD may return response information to the BMC. The BMC receives the response information returned by the CPLD and determines that the register value modification operation is successfully completed.

[0075] It is understandable that if the BMC cannot receive the response information returned by the CPLD, it can rewrite the register or send a prompt message to prompt the administrator that the writing fails.

[0076] Furthermore, the CPLD generates a corresponding control signal and sends it to the PCIe Switch according to the register value modified by the BMC. The control signal is used to adjust the routing configuration and port bandwidth allocation parameters inside the PCIe Switch. The PCIe Switch reconfigures its internal circuit structure according to the received control signal and sets at least one bandwidth of at least one device connected to each port. For example, the PCIe Switch can set the link speed and number of virtual channels of the port to set the bandwidth of each device.

[0077] In some optional embodiments, after the switch sets at least one bandwidth of at least one device, the baseboard management controller obtains the average throughput and average delay of each device in the at least one device within a preset time period; detects whether the average throughput and average delay of each device meet preset conditions, and the preset conditions are associated with the throughput and delay required by each device; if not, it is determined that the average actual bandwidth does not meet the business requirements of supporting each device, and each target bandwidth parameter value is adjusted.

[0078] The preset condition is that the average throughput of each device is greater than or equal to the throughput required by each device, and the average delay of each device is less than or equal to the minimum delay corresponding to each device.

[0079] Based on the above Figure 2 According to the method, the BMC can obtain bandwidth association information and current working status information of each device in at least one device associated with the host, as well as the priority of each device to configure the bandwidth; based on the priority, bandwidth association information and current working status information, determine each target bandwidth parameter value corresponding to each device to set at least one bandwidth of at least one device.

[0080] Since the target bandwidth parameter value is determined based on the bandwidth association information, current working status information and priority of each device, and the determined target bandwidth parameter value can be recorded in the corresponding register, the switch can set the bandwidth of each device based on the target bandwidth parameter value in the register. Compared with the method in the related art where the switch directly sets the default bandwidth for each device, the present invention can match the appropriate bandwidth parameter value for each device based on different working scenarios and the bandwidth association information of each device, thereby avoiding the waste of bandwidth resources or the problem of insufficient bandwidth of certain key devices, and improving the utilization rate of bandwidth resources.

[0081] In this embodiment, another bandwidth setting method is provided, which can be used for the above-mentioned baseboard management controller. Figure 3 is a flow chart of another bandwidth setting method according to an embodiment of the present invention. Figure 3 As shown, the process includes the following steps:

[0082] S301: The host is powered on.

[0083] S302: The BMC accesses at least one device associated with the host and determines whether the access is successful.

[0084] S303: If not, if the BMC access fails, the PCIeSwich sets the bandwidth of each device to the default bandwidth.

[0085] S304: If yes, the BMC obtains bandwidth association information, current working status information and priority of each device associated with the host.

[0086] S305: The BMC determines each target bandwidth parameter value corresponding to each device based on the priority, bandwidth association information and current working status information.

[0087] S306: The BMC determines whether to record each target bandwidth parameter value in a register corresponding to each device.

[0088] S307: If not, the register setting fails, and PCIeSwich sets the bandwidth of each device to the default bandwidth.

[0089] S308: If yes, PCIeSwich determines whether the target bandwidth parameter value recorded in the register is obtained.

[0090] S309: If not, obtaining the target bandwidth parameter value fails, and PCIeSwich sets the bandwidth of each device to the default bandwidth.

[0091] S310: If yes, the PCIeSwich sets at least one bandwidth of at least one device according to the target bandwidth parameter value.

[0092] In this embodiment, a bandwidth setting device is also provided, which is used to implement the above embodiments and preferred implementation modes, and the descriptions that have been made will not be repeated.
