The method provided by the embodiments of the present application can be applied to any required electronic device, for example, a server, a terminal and the like, which are not specifically limited here, and for the convenience of description, are simply referred to as electronic devices hereinafter.

[0049] According to an aspect of the embodiments of the present application, a method embodiment of a bandwidth allocation method of a server is provided. Figure 1 A flowchart of a bandwidth allocation method of a server according to an embodiment of the present application is provided, as shown in Figure 1 The method comprises the following steps.

[0050] Step S11, read the target resource information currently corresponding to the expansion card in the chassis where the target server is located.

[0051] The method provided by the embodiment of the application is applied to a baseboard management controller in a target server, and the baseboard management controller is mainly used for acquiring different resource information of an expansion board in a chassis where the target server is located, and performing different bandwidth allocation by using the resource information.

[0052] Specifically, reading the target resource information currently corresponding to the expansion card in the chassis where the target server is located includes the following steps A1-A2.

[0053] Step A1, read the expansion card type, expansion card model and expansion card position of the expansion card in the chassis where the target server is located.

[0054] Step A2, take the expansion card type, expansion card model and expansion card position as the target resource information.

[0055] In the embodiment of the application, after the baseboard management controller is powered on and started, the expansion card type, expansion card model and expansion card position of the expansion card in the chassis are read through an I2C bus. Specifically, the baseboard management controller can identify the expansion card type and expansion card model of the expansion card in the server processing S5 state through an I2C port. The expansion card type can be a graphics processing unit (GPU) type, a network interface controller (NIC) type, a memory type and the like. The expansion card model can be a specification corresponding to a graphics processing unit, a network interface controller and a memory. The expansion card position is used to indicate which PCIe Switch chip the expansion card is connected to. Based on this, the baseboard management controller takes the expansion card type, expansion card model and expansion card position obtained as the target resource information of the expansion card.

[0056] Step S12, acquire the target application scenario of the target server currently, and acquire the target bandwidth allocation strategy by using the target application scenario and the target resource information.

[0057] In the embodiment of the application, acquiring the target application scenario of the target server currently, and acquiring the target bandwidth allocation strategy by using the target application scenario and the target resource information includes the following steps B1-B3.

[0058] Step B1, acquire the topology structure of the target server currently, and determine the target application scenario of the target server currently by using the topology structure.

[0059] In the embodiment of the present application, the target application scenario of the target server is determined by using the topology structure, including: obtaining an application scenario library, wherein the application scenario library includes preset topologies of the target server in multiple application scenarios; and determining the application scenario of the preset topology in the application scenario library that matches the topology as the target application scenario.

[0060] In the embodiment of the present application, in order to avoid manual query of the current application scenario of the target server, an application scenario library is set in the baseboard management controller, thereby improving the query efficiency of the current application scenario of the target server. The application scenario library includes preset topologies of the target server in multiple application scenarios, as shown in FIG. 1, the topologies of the server in different application scenarios are different. Based on this, the baseboard management controller can directly obtain the topology of the target server by detecting the connection information of each PCIe switch chip, the connection information includes: which expansion cards are connected to the PCIe switch chip, and then the application scenario of the preset topology in the application scenario library that matches the topology is determined as the target application scenario. Figures 2 to 4

[0061] Step B2, obtaining the target bandwidth demand of the target resource information of the target server in the target application scenario.

[0062] In the embodiment of the present application, the resource information of the target server in different application scenarios corresponds to different bandwidth demands, that is, it can be understood that the same expansion card type corresponds to multiple different expansion card models, and each expansion card model corresponds to different bandwidth demands. Based on this, in order to facilitate the baseboard management controller to quickly determine the bandwidth demand of the target resource information, the bandwidth demand corresponding to each expansion card model is pre-configured, so that the baseboard management controller can directly query the matching bandwidth demand by using the expansion card model in the target resource information, and determine the bandwidth demand as the target bandwidth demand. The bandwidth demand is a specific bandwidth value required by the expansion card.

[0063] Step B3, obtaining the target bandwidth allocation strategy that matches the target bandwidth demand from a bandwidth allocation strategy set, wherein the bandwidth allocation strategy set includes multiple bandwidth allocation strategies, and different bandwidth allocation strategies are used to configure the PCIe port of the PCIe switch chip into different PCIe bandwidths.

[0064] In the embodiment of the present application, after obtaining the bandwidth demand, the baseboard management controller queries the bandwidth allocation strategy set, and the bandwidth allocation strategy set includes the correspondence between the bandwidth demand and the bandwidth allocation strategy. The bandwidth allocation strategy includes: uplink and downlink PCIe port number, port bandwidth type, etc. The target bandwidth allocation strategy corresponding to the target bandwidth demand is determined from the above correspondence. ​

[0065] Step S13, configure the PCIe Switch chip of the target server by using the target bandwidth allocation strategy, so that the PCIe Switch chip performs bandwidth allocation according to the target bandwidth allocation strategy after being powered on in the target server.

[0066] In the embodiment of the present application, the PCIe Switch chip of the target server is configured by using the target bandwidth allocation strategy, including the following steps C1-C2:

[0067] Step C1, generate a configuration instruction by using the target bandwidth allocation strategy.

[0068] Step C2, configure the level data of the power-on configuration pins of the PCIe Switch chip by calling the GPIO interface based on the configuration instruction.

[0069] In the embodiment of the present application, the baseboard management controller first converts the target bandwidth allocation strategy into target level data of the power-on configuration pins in the PCIe Switch chip based on the association between the bandwidth allocation strategy and the level data, and the target level data includes the level values corresponding to each power-on configuration pin of the PCIe Switch chip. It can be understood that the level data of the power-on configuration pins represents the bandwidth allocation strategy allocated by the baseboard management controller to the PCIe Switch chip.

[0070] Based on this, the method provided in the embodiment of the present application realizes automatic allocation of PCIe bandwidth according to the bandwidth demand of the expansion card, does not need a configuration file, and realizes automatic and rapid allocation of PCIe bandwidth by determining the bandwidth allocation strategy of the bandwidth demand and converting it into level data.

[0071] In the embodiment of the present application, the baseboard management controller generates a configuration instruction by using the target bandwidth allocation strategy to convert the target level data, and the configuration instruction carries the level values of each power-on configuration pin. Then, the baseboard management controller configures the level data of the power-on configuration pins of the PCIe Switch chip by calling the GPIO interface through the configuration instruction, that is, configures the level data of each power-on configuration pin of the PCIe Switch chip according to the level values carried by the configuration instruction. Subsequently, after being powered on, the PCIe Switch chip performs bandwidth allocation according to the level values of the power-on configuration pins.

[0072] As an example, the PCIe Switch chip includes 4 power-on configuration pins, the pin identifiers of the 4 power-on configuration pins are 01, 02, 03, and 04, and meanwhile, 4 GPIO interfaces are needed, the interface identifiers of the 4 GPIO interfaces are 1-1, 1-2, 1-3, and 1-4 respectively. Assuming that the obtained target level data is 0001, and the target level data in the target level value combination is arranged in the order of the number of the power-on configuration pins, at this time, the baseboard management controller first configures the level value of the GPIO interface with the interface identifier 1-1 as 0, the level value of the GPIO interface with the interface identifier 1-2 as 1, the level value of the GPIO interface with the interface identifier 1-3 as 1, and the level value of the GPIO interface with the interface identifier 1-4 as 0. Correspondingly, the level value of the power-on configuration pin with the configuration pin identifier 01 corresponding to the GPIO interface with the interface identifier 1-1 is 0, the level value of the power-on configuration pin with the configuration pin identifier 02 corresponding to the GPIO interface with the interface identifier 1-2 is 1, the level value of the power-on configuration pin with the configuration pin identifier 03 corresponding to the GPIO interface with the interface identifier 1-3 is 1, and the level value of the power-on configuration pin with the configuration pin identifier 04 corresponding to the GPIO interface with the interface identifier 1-4 is 0. That is, the PCIe bandwidth is allocated to the PCIe Switch chip according to the bandwidth allocation strategy corresponding to the target level data 0110.

[0073] In addition, when the current application scenario of the server is an Nvme or a Riser card, flexible bandwidth allocation can also be performed through the GPIO interface. In this way, it is ensured that the baseboard management controller has learned the resource information of the expansion card before power-on, and can correctly configure the bandwidth allocation strategy of the PCIe Switch chip during power-on of the PCIe Switch chip.

[0074] The method provided by the embodiment of the present application automatically identifies the bandwidth requirement of the expansion card in the current application scenario by using the baseboard management controller, configures a corresponding bandwidth allocation strategy according to the bandwidth requirement of the expansion card, and finally automatically allocates PCIe bandwidth to the PCIe Switch chip by using the bandwidth allocation strategy. The automatic allocation of the PCIe bandwidth is realized through the resource information of the expansion card, even when the application scenario of the server changes, manual configuration of a file carrying the bandwidth allocation strategy by a staff is not needed, and more application scenarios can be flexibly adapted.

[0075] According to another aspect of the embodiment of the present application, a bandwidth allocation method of a server is also provided, Figure 5 A flowchart of the bandwidth allocation method of the server provided by the embodiment of the present application is shown in Figure 5

[0076] ​Step S21: Monitor the target level data of the power-on configuration pin of the PCIe Switch chip, wherein the target level data is configured by the baseboard management controller in the target server using the target bandwidth allocation strategy.

[0077] Step S22: Obtain the target bandwidth allocation strategy using the target level data, and allocate bandwidth according to the target bandwidth allocation strategy.

[0078] The method provided in this application is applied to a PCIe Switch chip. After the PCIe Switch chip is powered on, it monitors the voltage levels of each power-on configuration pin and obtains the final target voltage level data based on the voltage levels and the pin identification order of the power-on configuration pins. The PCIe Switch chip uses the obtained target voltage level data to acquire the corresponding target bandwidth allocation strategy and allocates PCIe bandwidth to each PCIe port of the PCIe Switch chip according to the target bandwidth allocation strategy.

[0079] The method provided in this application configures the level values ​​of each power-on configuration pin in the PCIe Switch chip through the baseboard management controller, so that after the server is powered on, the PCIe Switch chip monitors the level values ​​of the power-on configuration pins to obtain target level data. This realizes automatic bandwidth allocation using the target bandwidth allocation strategy corresponding to the target level data, and at the same time enables the PCIe Switch chip to avoid customizing differentiated configurations for multiple configurations.
