[0059] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be described clearly and completely. Obviously, the described embodiments are only a part of the embodiments of the present application, but not all embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0060] The core of the present application is to provide a computer system, a bandwidth configuration method, a product, a server and a medium, so as to solve the problems of the limitation of only one bandwidth type corresponding to the first preset protocol and poor compatibility in the conventional bandwidth configuration.

[0061] The development demand of the Internet promotes the continuous development of infrastructure. In the current Internet era, the server is the most important basic equipment of various Internet manufacturers. Different businesses are arranged on the server to meet the use needs of different Internet groups. Further, different business scenarios require different components inside the server to be matched to achieve. Common components include network cards, intelligent network cards, hard disks, redundant array of independent disks (RAID) cards, etc.

[0062] Corresponding to the Peripheral Component Interconnect Express (PCIE) device, such as a Graphics Processing Unit (GPU), a network card, an intelligent network card, etc., the interface form meets the Peripheral Component Interconnect Express Card Electromechanical Specification (PCIE CEM) of the high-speed serial computer expansion bus standard, and is connected to the PCIE mark slot at the end of the server mainboard in the form of a golden finger. The PCIE mark slot is divided into X4, X8, X16, etc. X4, X8, X16 here refers to the PCIE bandwidth. The PCIE CEM specification is a detailed specification about the physical size, shape, connector and hot plug characteristics of the PCIE card. It ensures the compatibility between the PCIE cards and slots produced by different manufacturers.

[0063] The core of the smart NIC is to assist the central processing unit (CPU) to process network load through the field-programmable gate array (FPGA), program network interface functions, and release part of the resources of the server CPU and dual in-line memory module (DIMM) as the master device of the server. The smart NIC can ensure the maximum processing capacity for the application. At the same time, the smart NIC can also provide distributed computing resources, so that users can develop their own software or provide access services, thereby accelerating specific applications. With the exponential growth of data, enterprises and cloud providers require servers and computing resources to have higher performance to analyze a large amount of data in real time. Therefore, the ability of the smart NIC to release the resources of the server CPU and the DIMM is increasingly valuable, the role of the smart NIC in the entire data center is becoming more and more important, and the application scenarios of the smart NIC are becoming increasingly diversified.

[0064] Unlike common PCIE devices, the smart NIC internally contains key devices such as FPGAs, baseboard management controllers (BMCs), and complex programmable logic devices (CPLDs), which ensure that the smart NIC can run as an independent system. The FPGA inside the smart NIC is a PCIE terminal device connected to the server system, and the maximum bandwidth supported by the FPGA itself is X16. At the same time, under different configurations, it can be presented as one X16 or two X8 devices. The implementation of the configuration here is determined by the firmware burned in the FPGA itself. When allocated as two X8 devices, a single smart NIC can simultaneously connect two server systems to realize the multihost function (multi-host support), further expand the application scenarios of the smart NIC, and improve the value and efficiency of a single smart NIC. However, the actual situation of the current server system motherboard or adapter card cannot meet this 2X8 application situation, which will inevitably limit the application scenarios of the smart NIC, which is contrary to the increasingly diversified needs of the current smart NIC.

[0065] In a conventional bandwidth configuration process, only one type of bandwidth can be used. FIG. 1 is a system architecture diagram of a conventional expansion card system of a general network card. As shown in FIG. 1, a gold finger of a mainboard connector and an expansion card is connected by a cable to realize connection of a X16 bandwidth PCIE signal in the server mainboard to a PCIE X16 slot of the expansion card. After a system management bus (SMBUS) signal corresponding to an inter-integrated circuit (I2C) of the server is connected to the expansion card, 4-way I2C signals are converted by a first processor (I2C-to-multiple processor, such as CA9646), which are Channel[3:0], and I2C after channel0 is connected to a field replaceable unit (FRU), a temperature sensor (Temp Sensor), an input output (IO) expansion processor (such as CA9555) and the like in the expansion card. The use process of the expansion card of one type of bandwidth in FIG. 1 has limited corresponding functions, and cannot realize a configuration process of multiple types of bandwidth on one expansion card. The expansion card provided in the present application can solve the above technical problems.

[0066] Compatibility of different bandwidth types generally refers to the ability of devices with different rates or performance to work together in a computer network or data communication system. Key factors to ensure compatibility of different bandwidth types include:

[0067] 1. Adaptive technology: Many devices and interfaces use adaptive technology, which can automatically detect the performance of the other end of the connection and adjust its own rate to match.

[0068] 2. Backward compatibility: New technologies or standards are usually designed to be backward compatible, that is, they can work with old versions of devices or technologies, although at a lower rate.

[0069] 3. Protocol support: Network protocols are designed to allow devices of different rates to communicate through the protocol, for example, Ethernet can support rates from 10 Mbps to 100 Gbps.

[0070] 4. Rate limiting: In some cases, the system may need to manually configure rate limiting to ensure that devices of different bandwidths can work together without causing data loss or overload.

[0071] 5. Switches and routers: Network switches and routers are usually designed to support multiple rates and types of connections, and can intelligently handle data streams of different bandwidths.

[0072] 6. Signal modulation: In wireless communication, different modulation techniques can be used to accommodate different bandwidth requirements, for example, more complex modulation schemes can provide higher data rates.

[0073] 7. Encoding and decoding techniques: Devices compatible with different bandwidths may need to use the same encoding and decoding techniques to ensure accurate data transmission.

[0074] 8. Buffering and flow control: Buffering can be used to balance data flow between devices of different rates, while flow control mechanisms can prevent data overflow or loss.

[0075] 9. Middleware: In some cases, using middleware or adapters can serve as a bridge between devices of different bandwidths, providing necessary conversion or adaptation functions.

[0076] 10. Standards and specifications: Following common standards and specifications helps ensure compatibility between different devices and systems.

[0077] When designing and deploying systems, it is important to consider the bandwidth compatibility of different devices to ensure the performance and reliability of the entire system. As technology evolves, new solutions and standards are emerging to improve compatibility between different bandwidth types.

[0078] Figure 2 is a schematic diagram of a computer system according to an embodiment of the present application. As shown in Figure 2, it includes an expansion card 1, which includes a slot 4 and a connector 2.

[0079] The slot 4 defines configuration information corresponding to the target bandwidth type according to the first preset protocol;

[0080] The connector 2 is used to connect the slot 4 to the server motherboard 10;

[0081] The slot 4 is connected to the corresponding device 11, and is used to send the storage information of the device 11 to the server motherboard 10;

[0082] The server motherboard 10 is used to identify the target bandwidth type according to the storage information of the device, and to distribute the configuration information corresponding to the device 11 according to the target bandwidth type.

[0083] Specifically, in some embodiments, the slot in the expansion card is used to connect and install various expansion cards using the first preset protocol interface, allowing users to add or upgrade hardware devices such as GPUs, solid state drives, network cards, sound cards, etc. as needed. The corresponding transmission rate is not limited and can be set according to actual conditions, including but not limited to:

[0084] PCIe1.0: Maximum rate up to 250MB / s (per lane);

[0085] PCIe2.0: up to 500 MB / s (per lane);

[0086] PCIe3.0: up to 985 MB / s (per lane);

[0087] PCIe4.0: up to 1.98 GB / s (per lane);

[0088] PCIe5.0: up to 3.96 GB / s (per lane);

[0089] The slot has different lengths and numbers of lanes, and common ones are X4, X8, X16, etc. The more lanes the slot has, the stronger its data transmission capability is. When selecting an expansion card, it is necessary to ensure that the interface type and number of lanes of the card are compatible with the slot of the mainboard. The slot is configured according to the configuration information corresponding to the predefined target bandwidth type based on the first preset protocol. It can be understood that the predefined target bandwidth type is based on the configuration information of different target bandwidth types, which is listed through the slot mode, and at least one target bandwidth type. The specific process of predefinition can define the target bandwidth type that the reserved pins in the original slot want to be compatible with according to the first preset protocol, mainly adding the function definition of the pins.

[0090] Predefinition is mainly based on the redefinition of the reserved pins marked in the PCIE CEM specification to be compatible with various target bandwidth types.

[0091] The connector is used to connect the slot of the expansion card and the server mainboard, which can be in the form of a plug or a socket, and is mainly used for transmitting high-speed data. In some embodiments, the specific model and type of the connector are not limited, and can be set according to the actual situation, such as Mini Cool Edge Input Output (MICO), which can also be other Slimline connectors, etc. The MICO connector supports the transmission of high data rate signals and is commonly used in server, storage device, data center and network device application scenarios.

[0092] The slot is connected with the corresponding device, and the device is mainly an external peripheral component, such as a GPU, a network card, a smart network card, etc. The target bandwidth type of the device and the connector is the same. The slot is connected with the corresponding device, and the storage information of the device is mainly sent to the server mainboard. The storage information is the specific bandwidth information of the target bandwidth type, so as to identify the target bandwidth type according to the storage information. The configuration information of the device is distributed according to the target bandwidth type to complete the configuration requirement of the target bandwidth type of the device. The identification process can be determined by feature extraction or analysis and identification based on register information. The target bandwidth type of the present application can be one or more, which is not limited herein, but is of the same target bandwidth type at the same time. Multiple bandwidth types are included at different times, that is, multiple target bandwidth types are compatible on one expansion card.

[0093] In some embodiments of the present application, a computer system is provided, which includes an expansion card including a slot and a connector; the slot predefines the configuration information corresponding to the target bandwidth type according to a first preset protocol; the connector is used to connect the slot with the server mainboard; the slot is connected with the corresponding device, and is used to send the storage information of the device to the server mainboard; the server mainboard is used to identify the target bandwidth type according to the storage information of the device, and distribute the configuration information corresponding to the device according to the target bandwidth type. The slot predefines the configuration information corresponding to the target bandwidth type according to the first preset protocol. The first preset protocol in the conventional bandwidth configuration has the limitation of only one bandwidth type. The target bandwidth type can be set to different bandwidth types to improve the hardware compatibility of the expansion card. By setting the configuration information of each target bandwidth type, the devices under different bandwidth types can share a set of expansion cards under the computer system, realize the compatibility of different target bandwidth types, and further realize the seamless compatibility of each network card type.

[0094] In some embodiments, as shown in FIG. 2, the pads of the solder wire are used to connect the connector 2 with the slot 4 in the expansion card 1.

[0095] Specifically, the pad of the solder wire is a flat metal area used for soldering the solder wire in the electronic assembly process. The pad of the solder wire is a specific position designed for soldering with the pins or terminals of electronic components. The pad of the solder wire can be circular, square or any other shape, and its size and shape depend on the pin size and shape of the components to be soldered. As shown in FIG. 2, the pad of the solder wire is located between the connector and the slot. Each X8 bandwidth PCIE high-speed signal in the figure corresponds to one MCIO X8 connector.

[0096] In some embodiments, the pad of the solder wire is used to connect the connector and the slot, which ensures that the data transmission is as short and direct as possible, and helps to reduce signal loss and interference.

[0097] In some embodiments, as shown in FIG. 2, the connector 2 includes a connector male head and a connector female head; the connector male head is located in the expansion card 1; the connector female head is located in the server motherboard 10.

[0098] The connector male head and the connector female head are connected in a plug-in manner to realize the connection between the server motherboard 10 and the expansion card 1.

[0099] Specifically, as shown in FIG. 2, taking two MCIO x8 connectors as an example, the connector 1' corresponds to the target bandwidth type, and the connector 2' corresponds to the target bandwidth type. One MCIO x8 connector male head can be plugged into the MCIO x8 connector female head of the server motherboard. The connector male head and the connector female head are connected through mechanical interlocking and electrical contact. When connected, the pins of the male head are aligned with and tightly combined with the pins of the female head to form a closed circuit.

[0100] The connector male head usually refers to a plug, which is designed to be plugged into the female head. The male head has protruding pins, which can be needle-shaped, cylindrical or other shapes. When connected, the pins of the male head are inserted into the corresponding holes of the female head to achieve electrical connection.

[0101] The connector female head usually refers to a socket, which is designed to receive the insertion of the male head. The female head has grooves or holes inside, which match the pins of the male head. The female head is usually fixed on a device or a panel, such as a Universal Serial Bus (USB) port on a computer motherboard, a wall socket, etc. The female head is designed to be more stable in maintaining the connection, as it does not need to bear the mechanical stress of frequent plugging and unplugging.

[0102] When designing a connector, the shape, size, spacing and material of the pins need to be considered to ensure reliable connection and signal transmission. The locking mechanism of the connector, such as snap, screw lock or push-pull lock, also needs to be considered to prevent accidental disconnection during use.

[0103] In some embodiments, the connector female head is located in the server motherboard, and the connector male head is located in the expansion card, which is connected in a plug-in manner to realize the connection between the server motherboard and the expansion card, to ensure the interchangeability and flexibility between electronic devices.

[0104] In some embodiments, when the target bandwidth type is N*M bandwidth type, the number of connectors is N, and the slot pins of the slot are pre-defined with N*M bandwidth type configuration information; wherein N and M are positive integers.

[0105] Specifically, the number of connectors is N, and the corresponding slot pin of the connector defines the configuration information of N bandwidth types; for example, when the target bandwidth type is a 2X8 bandwidth type, the number of connectors is 2, and the preset slot pin of the first preset protocol slot respectively defines the configuration information of the 2X8 bandwidth type. When the target bandwidth type is a 4X4 bandwidth type, the number of connectors is 4, and the preset slot pin of the first preset protocol slot respectively defines the configuration information of the 4X4 bandwidth type. When the target bandwidth type is a 1X8 bandwidth type or a 1X4 bandwidth type, the number of connectors corresponds to 1, and the preset slot pin of the first preset protocol slot corresponds to the configuration information of the 1X8 bandwidth type or the 1X4 bandwidth type.

[0106] In some embodiments, the slot pin of the slot includes a reference clock pin, an independent reset pin, and a channel information pin corresponding to the target bandwidth type based on the first preset protocol.

[0107] Specifically, whether it is a target bandwidth type or a plurality of bandwidth types, the slot pin includes a reference clock pin (CLK pin), an independent reset pin (RESET pin), and a channel information pin (PCIE_Gen pin) corresponding to the target bandwidth type based on the first preset protocol. When there are a plurality of bandwidth types of slot pins, the corresponding different groups of slot pins need to be defined based on the reserved slot pin of the slot, which includes the three pin names mentioned above.

[0108] In some embodiments, the number of devices is the same as the number of bandwidth types of the target bandwidth type.

[0109] It can be understood that when configuring the corresponding device, the number of bandwidth types of the target bandwidth type needs to be the same to ensure the storage of the respective configuration information.

[0110] In some embodiments, the setting process of the target bandwidth type and the pin information of the slot pin ensure the universality and compatibility of the target bandwidth data in the same expansion card, and save the occupied area of the expansion card.

[0111] In some embodiments, as shown in FIG. 2, the expansion card 1 further includes a first component 5 and a first processor 6;

[0112] The first component 5 is connected with the first processor 6 and connected with the server mainboard 10.

[0113] The first processor 6 is connected with the slot 4.

[0114] Specifically, the first component is used for replacing the device component on site or at the user's location without the need for maintenance or replacement of the entire system. The first component is usually stored in a non-volatile storage, and by reading the memory of the first component, product number, manufacturer, etc. information can be obtained. Here, the storage information is obtained to facilitate subsequent maintenance and replacement operations.

[0115] The first processor is used to convert the signal into a 4-way I2C signal. The first component is connected to the first processor, the first component is connected to the server mainboard, and the first processor is connected to the slot.

[0116] The relationship between the first component and the first processor provided in some embodiments facilitates the server mainboard to receive the storage information of the device stored by the first processor and identify the corresponding target bandwidth type.

[0117] In some embodiments, as shown in FIG. 2, the expansion card further comprises a connector 7.

[0118] The connector 7 is connected to the slot 4.

[0119] Specifically, the connector is used to connect the interface or pin configuration required by the second preset protocol device. It can be a physical connector for second preset protocol communication, including data lines and clock lines, etc. The second preset protocol is different from the first preset protocol and is used for data transmission, which specifically allocates bandwidth and other information. The connector is connected to the slot. The connector can be an I2C Header, and it can also be a connector of other protocols.

[0120] It should be noted that the number of connectors is the same as the number of bandwidth types of the target bandwidth type. In FIG. 2, two X8 target bandwidth types are taken as an example, which correspond to two connectors, namely connector 1' and connector 2'. For example: two I2C Headers are placed in the expansion card, which can be connected to the server mainboard in the form of a cable. When an x16 bandwidth smart network card or a normal network card is needed, only one I2C Header is needed, and when a 2x8 bandwidth smart network card is needed, two I2C Headers are connected to two server mainboards respectively.

[0121] In some embodiments, the connector 7 is also connected to the first processor 6.

[0122] The connector is connected to the first processor. Here, the storage information is stored in the first processor so that the first processor can be given to the server mainboard through the first component, that is, the device is interacted through the second preset protocol to which the connector belongs, so as to facilitate the subsequent power-on control logic and bandwidth allocation requirements.

[0123] In some embodiments, a second processor is further included.

[0124] The second processor is connected to the slot and the connector, and is connected to the first processor.

[0125] Specifically, as shown in FIG. 2, the second processor 8 is connected to the slot 4 and the connector 7, and is connected to the first processor 6. The second processor functions as an arbitration function, and is used for the design of the dual-master I2C bus application requiring high reliability. The second processor has an intelligent arbitration function, and can select one master as a winner when two masters compete to use the bus, so that the winner can complete the operation without interference. The failed master takes over the control of the bus after the winner completes the operation or the reserved time expires. Software reset is also supported, which allows the master to send a reset command through the I2C bus. The registers of the second processor are reset to the power-on reset state. In addition, the identity document (ID) of the second processor can be read by the master, which contains the manufacturer, device type and version information. After a period of inactivity of more than 100 milliseconds, the second processor can automatically disconnect the downstream bus from the two masters to avoid bus lock.

[0126] The second processor also provides an interrupt output for indicating which master has the control of the bus and which master loses the use of the downstream bus. In addition, the second processor also has a bus initialization and recovery function, which allows remote recovery when the I2C bus is suspended.

[0127] In terms of electrical characteristics, the second processor supports voltage level conversion, allowing 1.8V, 2.3V, 2.5V and 3.3V devices to communicate with 3.3V devices without additional protection. In addition, all I / O pins of the processor can tolerate a voltage of 3.6V, and the design takes into account hot insertion and low on-resistance switches to support high data rate transmission.

[0128] The applications of the second processor include but are not limited to high-reliability systems, I2C bus applications with dual master, bus initialization and recovery, and allowing masters without arbitration logic to share resources.

[0129] In some embodiments, the connection relationship of the second processor provided improves the efficiency of data transmission, avoids bus lock and completes the operation without interference.

[0130] It can be understood that the reserved slot pins are redefined according to the function definition table of the reserved pins in Table 1. As shown in Table 1, the reserved pins A19, A32, A33, A50, B82 marked in the PCIE CEM specification are redefined. On the basis of compatibility with the specification, the design goal of compatible 2X8 smart network card and X16 smart network card and ordinary network card is achieved. The latest function definition of each pin is defined in combination with FIG. 2, and the difference points from the PCIE CEM specification are listed as follows:

[0131] Table 1

[0132] As shown in Figure 2, in combination with Table 1, part of the newly predefined pin information is shown, in which the connector 1' of the target bandwidth type corresponds to two pins A13 and A14 connected with the slot for the transmission of the clock signal; the pin A11 is used for the reset signal of the connector 1' of the target bandwidth type; the connector 2' of the target bandwidth type corresponds to two pins A32 and A33 connected with the slot for the transmission of the clock signal; the pin A50 is used for the reset signal of the connector 2' of the target bandwidth type; the two pins B5 and B6 connected with the slot of the connector 1' are used for the transmission of the system management bus; the two pins A19 and B82 connected with the slot of the connector 2' are used for the connection of the system management bus. The expansion card compatible with the X16 and 2X8 bandwidth intelligent network card and the ordinary PCIE device is used in the form of soldering pad, and each X8 bandwidth PCIE high-speed signal corresponds to an MCIO X8 connector male head, which can be connected to the MCIO X8 connector female head of the server mainboard. Two I2C headers are placed in the expansion card, which can be connected to the server mainboard in the form of cable. When the X16 bandwidth intelligent network card or the ordinary network card is used, only one I2C header is needed, and when the 2X8 bandwidth intelligent network card is used, two I2C headers are connected to two server mainboards respectively.

[0133] The BMC and the BIOS identify the memory of the adapter card through the I2C link, learn that the current adapter card is a specially defined adapter card, and then the BMC and the BIOS communicate with the device behind the PCIE slot through the I2C link to obtain whether the current inserted device is an intelligent network card or an ordinary network card, identify the device type, and then the BMC and the BIOS respectively inform the CPLD, and the CPLD automatically selects the corresponding power-on control logic.

[0134] After the BIOS communicates with the device behind the PCIE slot, it confirms whether the device type is an x16 bandwidth intelligent network card or a 2x8 bandwidth intelligent network card, or an ordinary intelligent network card, and automatically allocates the required PCIE bandwidth. When the device type is an x16 bandwidth intelligent network card or an ordinary network card, the BIOS allocates 1x16 bandwidth, and when the device type is a 2x8 bandwidth intelligent network card, the BIOS allocates 2x8 bandwidth, so as to meet the demand of different devices for PCIE bandwidth.

The S0 state here is the standard working state in the computer system, in which all components of the computer are in a fully running and responsive state, and the user can normally use the computer for work and entertainment. The S5 state is referred to as a "soft shutdown" state or a "complete shutdown" state, which is a defined state in computer power management, indicating that the computer has been completely shut down and does not consume power except for maintaining the real-time clock and other basic monitoring functions.
