Description

Technical Field

[0001] The present invention relates to the technical field of servers, and in particular to a method, device, equipment and medium for processing a network card in a server. Background Art

[0002] With the development of information technology, servers are increasingly used. In industries such as government, finance, healthcare, and energy, there's a growing demand for large core databases, virtualization consolidation, in-memory computing, and high-performance computing. Many modern services rely on high-performance computing (HPC), such as weather forecasting, DNA sequencing in biology, complex model deduction in physics, aerospace simulation in the industrial sector, and artificial intelligence. These applications require massive amounts of computing power, using scientific computational models to simulate and deduce data.

[0003] High-performance computing is often achieved through computing clusters composed of a large number of stacked high-performance computing hardware. Multi-node servers can support multiple computing nodes on a single server, and each computing node can support multiple CPUs. Therefore, multi-node servers are widely used in HPC scenarios and are typically equipped with high-bandwidth network cards to support large data throughput. OCP3.0 network cards are a common high-bandwidth network card. Currently, each computing node in a multi-node server requires a separate OCP3.0 network card for data communication between nodes and between node servers. It is also impossible to share the Multi-Host OCP3.0 network card function among different computing nodes. As a result, the application component cost of multi-node servers is high, the server structure is fixed, and the structural flexibility and scalability are lacking. Summary of the Invention

[0054] To make the above-mentioned objects, features, and advantages of the present invention more clearly understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0055] In order to enable those skilled in the art to better understand the technical solutions in the embodiments of the present invention, some technical features involved in the embodiments of the present invention are explained and illustrated below:

[0056] High-performance computing (HPC) refers to the use of supercomputers or computer clusters to solve complex scientific, engineering, and business problems. HPC systems typically consist of large numbers of processors, memory, and storage resources, enabling massively parallel computing to process massive amounts of data and execute complex simulations.

[0057] The Open Compute Project (OCP) is an open-source hardware project launched by Facebook in 2011 to design more efficient and cost-effective data center hardware. OCP's goal is to drive innovation and cost-effectiveness in data center hardware through open standards and shared designs.

[0058] OCP3.0 card refers to a network interface card (NIC) that complies with the OCP3.0 specification. As part of the OCP project, the OCP3.0 card is designed to provide high-bandwidth, low-latency data communication and is suitable for high-performance computing (HPC) and data center environments.

[0059] The Multi-Host OCP3.0 network card (shared interface network card) is a network card designed for multi-node servers. It supports multiple computing nodes sharing the same network card for data communication. This design aims to improve resource utilization, reduce hardware costs, and simplify system architecture.

[0060] High-speed connectors are electronic connectors used for high-speed data transmission. They are typically used in computers, communications equipment, data centers, servers, and other applications that require high-bandwidth data transmission. These connectors must meet specific electrical performance standards, such as signal integrity, impedance matching, crosstalk control, and electromagnetic compatibility.

[0061] A BMC (Board Management Controller) is an embedded microcontroller designed specifically to monitor and manage server hardware components. The BMC operates independently of the rest of the server and communicates with external management systems through specific interfaces (such as IPMI and Redfish), providing functions such as system status monitoring, fault diagnosis, and firmware updates.

[0062] As an example, in order to achieve the high-performance computing required in various service areas, computing clusters composed of a large number of high-performance computing hardware stacks are often used. In these clusters, different computing hardware usually use high-bandwidth network cards for data communication. At present, multi-node servers with OPC network cards provide high computing power. However, since each computing node needs to be equipped with an independent OCP3.0 network card to achieve data communication between computing nodes and node servers, the component cost of the multi-node server is relatively high, and the connection structure between different nodes and network cards cannot be adjusted according to actual needs. The board card structure equipped with computing nodes has low flexibility and scalability.

[0063] To this end, in an embodiment of the present invention, any computing node is selected from the computing nodes of the server and a shared interface network card is inserted, and interface adapter cards are inserted into the remaining computing nodes. Based on the in-place signal of the interface adapter card, the network card connection mode of the current server is judged, and the control signals of the remaining computing nodes are received through the high-speed connector in the computing node. The control signals of different computing nodes are arbitrated through the arbitration unit to realize access connection of different nodes to the shared interface network card.

[0064] Reference Figure 1 , shows a flowchart of a method for processing a network card in a server provided in an embodiment of the present invention, wherein the server may include several computing nodes and network cards, there is a one-to-one correspondence between the computing nodes and the network cards, and each computing node has the same hardware structure. Exemplarily, the computing node includes at least an interface connector, a high-speed connector, and a logic device. Each network card is connected to the computing node via the interface connector on the computing node. The network card includes a shared interface network card and an interface adapter card. Specifically, the method may include the following steps:

[0065] S101 , in response to a power-on signal of a server, obtaining, through a first computing node, a presence signal corresponding to an interface adapter card in a second computing node.

[0066] In an embodiment of the present invention, based on the in-position signal of the interface adapter card in the second computing node, the network card connection mode of the current server can be determined, and the network card connection mode corresponding to the network card connection mode can be further executed, wherein the network card connection mode includes a shared connection mode and an independent connection mode. When the server is in the independent connection mode, refer to Figure 2 The computing node 1 in the server is equipped with an independent connection network card 1, and the computing node N is equipped with an independent connection network card N. Each computing node is independently equipped with an independent connection network card, resulting in a higher component cost for the multi-node server.

[0067] When the server system receives the power-on signal, it initializes the various components in the server, which may include a baseboard management controller and several computing nodes in the server. In the embodiment of the present invention, when it is necessary to enter the shared connection mode, refer to Figure 3The present invention uses two computing nodes to implement a shared network card connection as an example for explanation. Any computing node is selected from several computing nodes of a server as a first computing node, and a shared interface network card is inserted into the OCP connector of the first computing node. Preferably, the shared interface network card can be a Multi Host OCP 3.0 network card that supports multi-node sharing. Accordingly, to implement the shared connection mode, interface adapter cards are inserted into the remaining computing nodes other than the first computing node, and the remaining computing nodes are connected to the first computing node via high-speed cables to establish a transmission channel between the remaining computing nodes and the first computing node. For ease of distinction, in the embodiment of the present invention, the computing node inserted with the shared interface network card is referred to as the first computing node, and the computing node inserted with the interface adapter card is referred to as the second computing node. Before the network card is inserted, the first computing node and the second computing node are the same computing node. In each computing node, the interface connector (OCP connector) exchanges data with the central processing unit, and the interface connector also exchanges signals with the high-speed connector to obtain control signals for the network card. The network card is connected to the computing node through the interface connector.

[0068] Among them, the presence signal is a logic level signal, which can be used to indicate whether the interface adapter card in the second computing node has been inserted into the corresponding slot or connector. The presence signal includes a high level signal and a low level signal. Based on the reading of the presence signal, it can be determined whether the interface adapter card is inserted in the second computing node, that is, whether the shared connection mode is currently entered.

[0069] In one example, the first computing node can also receive the presence signal by obtaining the connection status of the high-speed cable on the first computing node. When entering the shared connection mode, while inserting the interface adapter card into the second computing node, the second computing node also needs to be connected to the first computing node through a high-speed cable, wherein one end of the high-speed cable is connected to the interface adapter card of the second computing node, and the other end is connected to the first high-speed connector of the first computing node. When receiving the power-on signal of the server, the first computing node can obtain the cable connection signal in the first high-speed connector to confirm whether there is a connected high-speed cable on the current first high-speed connector.

[0070] If the cable connection signal indicates that the first high-speed connector is connected to the high-speed cable, it indicates that there is currently a second computing node connected to the first computing node via a high-speed cable, and the first computing node and the second computing node will be connected only in the shared connection mode, that is, it can be confirmed that the in-place signal is a low-level signal, wherein the low-level signal is used to indicate that the current interface adapter card is in place. Correspondingly, if the cable connection signal indicates that the first high-speed connector is not connected to the high-speed cable, it indicates that there is currently no second computing node connected to the first computing node via a high-speed cable. At this time, the first computing node and the shared interface network card are in an independent connection state, that is, it can be confirmed that the in-place signal is a high-level signal, wherein the high-level signal is used to indicate that the current interface adapter card is not in place. Preferably, in the embodiment of the present invention, the high-speed connector on the computing node can select an MCIO high-speed connector to support high-speed data transmission.

[0071] S102 : If the presence signal is a low level signal, obtaining a first control signal of a first logic device in the first computing node and a second control signal of a first high-speed connector in the first computing node through the first computing node.

[0072] S103 , sorting the priorities of the first control signal and the second control signal by the first computing node to obtain a control signal sequence for the shared interface network card in the first computing node.

[0073] When the first computing node receives a low-level signal for the in-place signal, it indicates that an interface adapter card has been inserted into the current second computing node, that is, the server enters a shared connection mode. When the in-place signal is a high-level signal, it indicates that an interface adapter card has not been inserted into the current second computing node, and the server is in an independent connection mode. Since the first computing node and the second computing node are connected by a high-speed cable, and one end of the high-speed cable is connected to the first high-speed connector of the first computing node, the second control signal sent by the second computing node can be obtained by reading the transmission signal of the first high-speed connector. At the same time, the first control signal of the first computing node is read from the baseboard management controller (BMC).

[0074] The first control signal and the second control signal are transmitted to the arbitration unit to perform signal arbitration. For example, the first control signal and the second control signal can be prioritized by the I2C arbitration unit in the first computing node to obtain a control signal sequence for the shared interface network card in the first computing node, and the control signal sequence is sent to the interface connector to perform access control on the shared interface network card in the interface connector.

[0075] In one example, the first high-speed connector of the first computing node can also receive the second reset signal of the second computing node. At the same time, the first reset signal of the first computing node itself is received through the programmable logic device (CPLD). The reset signal is used to control the reset operation of the shared interface network card in the first computing node. Figure 4 The second computing node sets a high-speed connector in the interface adapter card, and the interface adapter card is connected to the interface connector through the gold finger of the interface connector. The second computing node sends the second control signal, the data interaction signal, and the second reset signal to the high-speed connector in the interface adapter card through the gold finger of the interface connector, and further transmits them to the high-speed cable through the interface adapter card and sends them to the first computing node. Based on the first reset signal and the second reset signal, the corresponding reset operation of the shared interface network card can be implemented.

[0076] Specifically, the control signal sequence can be obtained through the following steps:

[0077] Obtaining a first priority of the first control signal and a second priority of the second control signal;

[0078] According to a preset sorting strategy, the first control signal and the second control signal are prioritized to obtain a control signal sequence for the shared interface network card in the first computing node.

[0079] In an embodiment of the present invention, a priority can be set for the control signal of each computing node, or relevant parameters of the calculation priority can be calculated as needed. For example, the first control signal of the first computing node can be set to the first priority, and the priority of the second control signal can be set in turn according to the order of arrival of the control signals. The corresponding priority can also be set according to the urgency of the control signal, and the present invention is not limited here.

[0080] When multiple computing nodes simultaneously request access to the shared interface network card, the I2C arbitration unit prioritizes these requests according to a preset sorting strategy. For example, the first control signal and the second control signal are sorted in order from highest priority to lowest priority. The sorting result is a control signal sequence, which determines which computing node's BMC will first obtain access to the shared interface network card.

[0081] In one example, the first computing node can control the programmable logic device to send an adjustment signal corresponding to the network card connection mode based on the current network card connection mode, and adjust the working mode of the shared connection network card accordingly. Specifically, the adjustment signal corresponding to the shared connection mode is a shared connection signal, and the adjustment signal corresponding to the independent connection mode is an independent connection signal. When the adjustment signal sent by the logic device is a shared connection signal, it indicates that the server is in the shared connection mode, and the working mode of the shared interface network card can be adjusted to the shared connection mode through the first computing node; when the adjustment signal sent by the logic device is an independent connection signal, it indicates that the server is in the independent connection mode, and the working mode of the shared interface network card can be adjusted to the independent connection mode through the first computing node.

[0082] When a shared interface network card is inserted into the first computing node but is not connected to the other computing nodes through a high-speed cable, that is, when the server is in an independent connection mode, the first control signal of the first logic device can also be obtained through the first computing node, and an independent connection between the first computing node and the shared connection network card can be established according to the first control signal.

[0083] S104 , obtaining a plurality of second computing nodes from the computing nodes according to the control signal sequence through the first computing node, and generating a computing node sequence.

[0084] S105 , establishing a connection between the second computing node and the shared interface network card in sequence according to the computing node sequence.

[0085] The control signal sequence is a list of control signals obtained by sorting the first control signal and the second control signal according to priority, which can be used to guide the server on how to process these control signals. The first computing node determines the second computing node to be connected from the computing nodes of the server based on the generated control signal sequence, and prepares to establish a connection. Among them, the computing node sequence is a list of computing nodes obtained by sorting the computing nodes corresponding to the control signal sequence, which can be used to guide the server to establish connections between each computing node and the shared interface network card in the correct order.

[0086] Specifically, the first computing node can extract the second control signal from the control signal sequence, and obtain several second computing nodes corresponding to the second control signal in the control signal sequence from the computing node of the server. The first computing node extracts the first order of the first control signal and the second order of the second control signal from the control signal sequence, sorts the control signals corresponding to the first order and the second order, and generates a computing node sequence, which effectively solves the power-on timing problem of the network card when multiple computing nodes share one shared interface network card, and realizes the management problem of the shared interface network card by the baseboard management controller in each computing node.

[0087] Exemplarily, the network card on the computing node may also include an independent connection network card. When the second computing node receives a power-on signal from the server, it may obtain a gold finger signal from the interface connector on the second computing node, wherein the interface connector is in contact with the interface connection card through a gold finger, and the gold finger signal may indicate an insertion signal of the interface adapter card in the second computing node. When the gold finger signal indicates that the interface connection card is inserted into the second computing node, it may be determined that the shared connection mode is currently entered, and the in-place signal is controlled to be a low-level signal, and the second computing node sends the in-place signal to the first computing node through a high-speed cable. When the gold finger signal indicates that the interface connection card is not inserted into the second computing node, it may be determined that the independent connection mode is currently entered, and the in-place signal is controlled to be a high-level signal, and the second computing node sends the in-place signal to the first computing node through a high-speed cable. At the same time, in the independent connection mode, an independent interface network card is inserted into the second computing node, and the second computing node may directly obtain a third control signal from the second logic device in the second computing node, and establish a connection between the second computing node and the independent connection network card on the second computing node according to the third control signal.

[0088] In a possible embodiment, the network card connection method provided by the embodiment of the present invention can be implemented based on a specific connection structure in the server, referring to Figure 5 , showing a schematic diagram of signal transmission on an exemplary computing node in a method for processing a network card in a server provided by an embodiment of the present invention. The data channels of the interface connector can be numbered to obtain channels 0-15, wherein channels 0-7 of the interface connector are connected to the central processing unit of the computing node to implement data interaction, and channels 0-7 of the interface connector are connected to the x8 bandwidth PCIE defined on the high-speed connector to receive control signals transmitted by other computing nodes; when the second computing node confirms the insertion of the interface adapter card, it sends a presence signal to the first high-speed connector of the first computing node via a high-speed cable, which is transmitted by the first high-speed connector to the first logic device. The first logic device sends an adjustment signal to the interface connector based on the presence signal to adjust the working mode of the shared interface network card; based on the same transmission method, the second computing node can also send a second reset signal to the first high-speed connector of the first computing node via the high-speed cable, which is transmitted by the first high-speed connector to the interface connector. For example, the first reset signal can be transmitted to the A11 pin of the interface connector, and the first reset signal of the first computing node itself can be obtained from the first logic device. The shared interface network card is reset and controlled based on the first reset signal and the second reset signal;

[0089] Among them, when the first computing node detects that the first high-speed connector is connected to the interface adapter cards in the remaining computing nodes via a high-speed cable, the presence signal changes from a high-level signal to a low-level signal, indicating that it is in shared connection mode, that is, the first computing node currently supports shared interface network cards. When the presence signal is high, the control signal sequence output by the I2C arbitration unit after arbitration can be output to the A7 / A8 pin of the interface connector. This design implements the management and configuration of the independent interface network card in the second computing node. When the presence signal is low, the second control signal of the second computing node can be connected to the reserved pin of the interface connector, such as B68 / B69, and the second control signal is transmitted to the first computing node through the interface connector, thereby implementing the management and configuration of the shared interface network card in the first computing node by the second computing node.

[0090] An embodiment of the present invention provides a method for processing a network card in a server. In response to a power-on signal of the server, a first computing node obtains a presence signal corresponding to an interface adapter card in a second computing node. If the presence signal is a low-level signal, the first computing node obtains a first control signal of a first logic device in the first computing node and a second control signal of a first high-speed connector in the first computing node. The first computing node prioritizes the first control signal and the second control signal to obtain a control signal sequence for the shared interface network card in the first computing node. The first computing node obtains a plurality of second computing nodes from the computing node according to the control signal sequence and generates a computing node sequence. Connections between the second computing nodes and the shared interface network card are established in sequence according to the computing node sequence. An embodiment of the present invention selects any computing node from the computing nodes of the server and inserts a shared interface network card, and inserts interface adapter cards into the remaining computing nodes. Based on the in-place signal of the interface adapter card, the network card connection mode of the current server is judged, and the control signals of the remaining computing nodes are received through the high-speed connector in the computing node. The control signals of different computing nodes are arbitrated by the arbitration unit to realize the access connection of different nodes to the shared interface network card, effectively reducing the hardware burden of the server. Through the design of the connection structure, it is realized that connection modes with different requirements are supported in the same board card, thereby taking into account both data processing efficiency and hardware layout cost.
