Description

Technical Field

[0001] This invention relates to the field of computers, and more specifically to a method, apparatus, device, and readable medium that supports different models of smart network interface cards (NICs). Background Technology

[0002] The core of a SmartNIC is to assist the CPU (Central Processing Unit) in handling network load through an FPGA (Field-Programmable Gate Array), program the network interface functions, improve application and virtualization performance, and realize Software-Defined Networking (SDN) and Network Functions Virtualization (NFV). The goal is to free up expensive CPU computing resources on servers and provide maximum CPU processing power. In addition, SmartNICs provide distributed computing resources, allowing users to develop their own software or provide access services, thereby accelerating specific applications.

[0003] Currently, common smart network interface card (NIC) brands on the market include Yinsong, Alibaba MOC2.0, NVIDIA-Bluefied2, and NVIDIA-Bluefied3. These smart NICs have the same appearance and specifications as standard PCIe (Serial Bus) cards, expanding server NIC functionality by inserting into a PCIe slot. However, due to the high power consumption of smart NICs, an external power supply is required to meet their power needs. Some smart NICs also require an external NCSI (Network Controller Sideband Interface) connector to support ShareNIC functionality. Although smart NICs from different manufacturers appear similar, their power supply and PCIe signaling differ, and they are inconsistent with standard PCIe cards (generally standard NICs). Therefore, server systems typically require a dedicated PCIe slot designed specifically for a particular smart NIC. This slot cannot support other smart NICs or standard NICs, reducing the slot's expandability and flexibility. If a system needs to support multiple smart NICs, additional dedicated slots are required, significantly increasing design costs. Summary of the Invention

Obviously, the drawings described below are only some embodiments of the present invention. For those skilled in the art, other embodiments can be obtained based on these drawings without creative effort.

[0040] Figure 4 This is a schematic diagram of a computer-readable storage medium according to an embodiment of the present invention. Detailed Implementation

[0041] To make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be further described in detail below with reference to specific examples and the accompanying drawings.

[0042] Based on the above objectives, a first aspect of the embodiments of the present invention provides an embodiment of a method for supporting different models of smart network interface cards. Figure 1 The diagram shown is a schematic flowchart of the method.

[0043] like Figure 1 As shown, the method may include the following steps:

[0044] S1 connects the NCSI connector of the smart network card to the NCSI connector of the motherboard via an NCSI cable and inserts the gold fingers of the smart network card into the PCIe slot of the motherboard.

[0045] S2 switches the power supply timing of the motherboard based on the presence signal of the smart network card. A presence signal for the smart network card can be added to a reserved or preset pin in the NCSI connector of the motherboard, such as SMART_NIC_PRSNT_N, MOC_PRSNT_N, and LAN_CARD_PRSNT_N signals. When the smart network card's NCSI connector is connected to the motherboard's NCSI connector via an NCSI cable, the smart network card sends a presence signal to the motherboard's NCSI connector. The motherboard's NCSI connector determines the model of the smart network card based on the received presence signal. For example, when a smart network card is inserted into the motherboard, it sends a presence signal, and the SMART_NIC_PRSNT_N signal in the motherboard's NCSI connector is pulled from high to low. The motherboard can determine the model of the smart network card inserted into the motherboard based on this signal level change. Then, based on the model of the smart network card, it outputs the control signal P12V_STBY_EFUSE_EN to control the Efuse of the P12V_EDGE power supply on the motherboard, switching the power supply timing to STBY or Normal. For example, when the Silver Shirt smart network card is inserted into the motherboard, the power supply timing will be switched to STBY.

[0046] S3 switches between different PCIe bifurcation configurations based on the high and low levels of preset expansion pins in the motherboard's PCIe slots. The preset expansion pin in the motherboard's PCIe slots is monitored; this preset pin is B82. In the Yinsheng Smart Network Card's specifications, pin B82 is defined as an extension beyond the PCIe specification. In the Yinsheng Smart Network Card, this pin is a 1Kohm pull-up P3V3_AUX. This pin B82 is not used in other smart network cards, therefore it can be used as the basis for system PCIe bifurcation switching. When the system detects a high level on this pin, it indicates that the Yinsheng Smart Network Card is present, and the PCIe bifurcation is configured as x8x8. When the system detects a low level on this pin, it indicates that the Yinsheng Smart Network Card is not present, and the PCIe bifurcation is configured as x16.

[0047] By using the technical solution of this invention, a single PCIe slot can simultaneously support multiple smart network cards and standard network cards, improving the flexibility of a single slot and the expandability of the system, and effectively reducing design costs.

[0048] In a preferred embodiment of the present invention, the power supply timing of switching the motherboard power supply according to the presence signal of the smart network card includes:

[0049] The smart network card's NCSI connector connects to the motherboard's NCSI connector via an NCSI cable, and the smart network card sends an in-position signal to the motherboard's NCSI connector.

[0050] The NCSI connector on the motherboard determines the model of the smart network card based on the received presence signal;

[0051] Based on the model of the smart network card, the output control signal P12V_STBY_EFUSE_EN controls the effuse of the P12V_EDGE power supply on the motherboard.

[0052] The presence signal of the smart network card can be added to the reserved or preset pins in the NCSI connector of the motherboard. For example, SMART_NIC_PRSNT_N, MOC_PRSNT_N, and LAN_CARD_PRSNT_N signals can be added. When the NCSI connector of the smart network card is connected to the NCSI connector of the motherboard through the NCSI cable, the smart network card will send the presence signal to the NCSI connector of the motherboard. The NCSI connector of the motherboard determines the model of the smart network card based on the received presence signal. For example, when the SilverShan smart network card is inserted into the motherboard, it will send a presence signal to the motherboard. The SMART_NIC_PRSNT_N signal in the NCSI connector of the motherboard will be pulled from high level to low level. The motherboard can obtain the model of the smart network card inserted into the motherboard based on the change of this signal level. Some smart network cards (NICs) do not have an NCSI connector, such as the Alibaba MOC2.0 smart NIC. In these cases, the presence signal of the smart NIC needs to be sent to the motherboard via an NCSI cable. When the Alibaba MOC2.0 smart NIC is inserted into the motherboard, the MOC_PRSNT_N signal in the motherboard's NCSI connector is pulled from high to low, and the power supply timing is switched to 3.3VSTBY. When a standard NIC is inserted into the motherboard, the LAN_CARD_PRSNT_N signal in the motherboard's NCSI connector is pulled from high to low, and the power supply timing is switched to Normal.

[0053] In a preferred embodiment of the present invention, controlling the effuse of the P12V_EDGE power supply on the motherboard by outputting the control signal P12V_STBY_EFUSE_EN according to the model of the smart network card includes:

[0054] Switch the power supply sequence to STBY or Normal power according to the model of the smart network card.

[0055] In a preferred embodiment of the present invention, switching different PCIe bifurcation configurations based on the high or low level of a preset expansion pin in the PCIe slot of the motherboard includes:

[0056] In response to a high level on the B82 pin in the PCIe slot on the motherboard, the PCIe bifurcation is configured as x8x8;

[0057] In response to a low level on pin B82 in the motherboard's PCIe slot, the PCIe bifurcation is configured to x16. A preset extension pin in the motherboard's PCIe slot is monitored; this preset pin is B82. In the Yinsheng Smart Network Card's specifications, pin B82 is defined as an extension beyond the PCIe specification. In the Yinsheng Smart Network Card, this pin is a 1Kohm pull-up P3V3_AUX. This pin B82 is not used in other smart network cards, therefore it can be used as a basis for system PCIe bifurcation switching. When the system detects a high level on this pin, it indicates that the Yinsheng Smart Network Card is present, and the PCIe bifurcation is configured to x8x8. When the system detects a low level on this pin, it indicates that the Yinsheng Smart Network Card is not present, and the PCIe bifurcation is configured to x16.

[0058] By using the technical solution of this invention, a single PCIe slot can simultaneously support multiple smart network cards and standard network cards, improving the flexibility of a single slot and the expandability of the system, and effectively reducing design costs.
