Description

Technical Field

[0001] This invention relates to the field of chips, and more particularly to a server interface multiplexing method, a substrate management and control chip, a device, and a medium. Background Technology

[0002] A server is a computer system with a central processing unit (CPU) at its core. A baseboard manager controller (BMC) typically monitors the server's underlying hardware status and performs remote, unified management (installation, system updates, power on / off, etc.). The BMC itself needs to exchange data with the CPU through an interface to enable remote monitoring, management, installation, or system updates. External devices also need to exchange data with the CPU through interfaces on the server host. Therefore, this raises the issue of interface reuse between the BMC and CPU interfaces and between the server host and CPU interfaces.

[0003] In the related technologies of server interface reuse, data exchange between the server interface and the CPU is realized by integrating a southbridge chip on the server host. The southbridge chip is a chip used for communication between input / output ports. In each data exchange process, the integration of redundant interfaces causes a waste of interface resources. Furthermore, due to the low utilization rate of the interfaces on the baseboard management controller, the interfaces on the baseboard management controller are managed in the same way as other interfaces, which reduces the management efficiency of the server interfaces. Summary of the Invention

[0004] In view of this, the present invention proposes a server interface reuse method, a baseboard management control chip, a device, and a medium, which at least solves the problems in the above-mentioned related technologies of server interface reuse, such as the waste of interface resources caused by integrating a southbridge chip on the server host to realize data exchange between the server interface and the CPU during each data exchange process due to the integration of redundant interfaces, and the reduced management efficiency of the server interface due to the low utilization rate of the interfaces on the baseboard management controller and the unified management of the baseboard management controller's interfaces with other interfaces.

[0005] Based on the above objectives, one aspect of the present invention provides a server interface multiplexing method, comprising: receiving data from a first preset interface of a server host through a first port of an interface converter integrated on a baseboard management controller, and sending the data from the first preset interface to a processor of the server host through a second port of the interface converter for a first data exchange; in response to the processor of the baseboard management controller receiving a data exchange instruction, the interface converter receiving data sent from a second preset interface connected to the processor of the baseboard management controller through a third port, and sending the data sent from the second preset interface to the processor of the server host through the second port for a second data exchange.

[0006] In some embodiments, the method further includes: in response to the simultaneous receipt of data by the first port and the third port of the interface converter, determining the priority of the data from the first preset interface and the data from the second preset interface through an arbitration mechanism built into the interface converter; and sending the data from the first preset interface and the data from the second preset interface to the processor of the server host through the second port in order of priority, so as to perform the first data exchange and the second data exchange in order of priority.

[0007] In some embodiments, the arbitration mechanism includes: determining the priority of the first preset interface and the second preset interface according to the order specified by the user for the first data exchange and the second data exchange.

[0008] In some embodiments, the step of the interface converter receiving data sent from a second preset interface connected to the processor of the substrate management controller via a third port includes: configuring a switch for the second preset interface of the processor of the substrate management controller, wherein the state of the switch is set according to user requirements; and in response to the state of the switch being in an on state, the interface converter receiving data sent from the second preset interface connected to the processor of the substrate management controller via the third port.

[0009] In some embodiments, the method further includes: connecting a first preset interface of the server host to a first port of an interface converter integrated on the baseboard management controller via a universal serial bus.

[0010] In some embodiments, the step of sending data from the first preset interface to the processor of the server host through the second port of the interface converter for the first data exchange includes: in response to the fact that the interface protocol of the processor of the server host is different from the protocol of the first preset interface, sending data from the first preset interface to an interface conversion module integrated on the baseboard management controller through the second port of the interface converter; converting the data sent from the first preset interface into data conforming to the interface protocol of the processor of the server host through the interface conversion module and then sending it to the interface of the processor of the server host for the first data exchange.

[0011] In some embodiments, the step of sending the data sent by the second preset interface to the processor of the server host through the second port for a second data exchange includes: in response to the fact that the interface protocol of the processor of the server host is different from the protocol of the second preset interface, sending the data of the second preset interface to the interface conversion module integrated on the baseboard management controller through the second port of the interface converter; converting the data sent by the second preset interface into data that conforms to the interface protocol of the processor of the server host through the interface conversion module, and then sending it to the interface of the processor of the server host for a second data exchange.

[0012] In some embodiments, the number of ports of the interface converter is greater than the sum of the number of the first preset interfaces and the number of the second preset interfaces.

[0013] In another aspect of this invention, a baseboard management control chip for server interface multiplexing is provided, comprising: a processor of a baseboard management controller; and an interface converter, the interface converter including a first port, a second port, and a third port, and the interface converter being configured to: receive data from a first preset interface of a server host through the first port, and send the data from the first preset interface to the processor of the server host through the second port for a first data exchange; and, in response to the processor of the baseboard management controller receiving a data exchange instruction, receive data sent from a second preset interface connected to the processor of the baseboard management controller through the third port, and send the data sent from the second preset interface to the processor of the server host through the second port for a second data exchange.

[0014] In another aspect of the present invention, an electronic device is provided, including at least one processor; and a memory storing computer instructions executable on the processor, which, when executed by the processor, implement the steps of the above-described method.

[0015] In another aspect of the present invention, a computer-readable storage medium is provided, which stores a computer program that, when executed by a processor, implements the method steps described above.

[0016] The present invention has at least the following beneficial effects: The server interface reuse method proposed in this invention integrates an interface converter on the baseboard management controller, directly connecting the server host's interface to the interface converter. The interface converter sends data from the server host's interface to the server host's processor for a first data exchange. Simultaneously, when the baseboard management controller's processor receives a data exchange instruction, it can also send data from its connected interface to the server host's processor via the interface converter for a second data exchange. This achieves the reuse of the server host's interface and the baseboard management controller's interface, allowing for separate management of different interfaces, with reuse only possible when the interface is in use. This avoids the problem of wasted interface resources caused by unified management of all server interfaces. Furthermore, since the baseboard management controller's interfaces have low utilization, this reuse method improves the management efficiency of server interfaces.

[0017] Furthermore, by using an arbitration mechanism built into the interface converter to determine the priority of the data from the first preset interface and the second preset interface, the data from the first preset interface and the second preset interface are sent to the processor of the server host in sequence according to this priority order, so as to perform the first data exchange and the second data exchange respectively. This solves the problem of how to handle the situation where the first port and the second port receive data at the same time, and resolves the problem of data exchange conflict.

[0018] Furthermore, the arbitration mechanism built into the interface converter is user-specified and can adaptively switch in real time according to user needs, improving the flexibility and adaptability of the server's interface reuse.

[0019] Furthermore, a switch is configured for the second preset interface, and its switch state can be set according to user needs. Data can only be sent to the third port of the interface converter when the switch state is on, which avoids the accidental sending of data to the interface converter due to system misoperation and improves the accuracy of interface multiplexing.

[0029] Based on the above objectives, the first aspect of the present invention provides an embodiment of a server interface reuse method. Figure 1 The flowchart shown is a method for reusing server interfaces provided in an embodiment of this application. Figure 1 As shown, a method for reusing server interfaces includes:

[0030] S1. Receive data from a first preset interface of the server host through the first port of the interface converter integrated on the baseboard management controller, and send the data from the first preset interface to the processor of the server host through the second port of the interface converter for first data exchange;

[0035] According to several embodiments of the present invention, the method further includes: connecting a first preset interface of the server host to a first port of an interface converter integrated on the baseboard management controller via a universal serial bus.

[0036] According to several embodiments of the present invention, the step of sending data from a first preset interface to a processor of a server host through a second port of an interface converter for a first data exchange includes: in response to the fact that the interface protocol of the processor of the server host is different from the protocol of the first preset interface, sending data from the first preset interface to an interface conversion module integrated on a baseboard management controller through the second port of the interface converter; converting the data sent from the first preset interface into data conforming to the interface protocol of the processor of the server host through the interface conversion module and then sending it to the interface of the processor of the server host for the first data exchange.

[0037] According to several embodiments of the present invention, the step of sending data sent by a second preset interface to a processor of a server host through a second port for a second data exchange includes: in response to the difference between the interface protocol of the processor of the server host and the protocol of the second preset interface, sending data of the second preset interface to an interface conversion module integrated on the baseboard management controller through the second port of the interface converter; converting the data sent by the second preset interface into data conforming to the interface protocol of the processor of the server host through the interface conversion module and then sending it to the interface of the processor of the server host for a second data exchange.

[0038] According to several embodiments of the present invention, the number of ports of the interface converter is greater than the sum of the number of the first preset interface and the number of the second preset interface.

[0039] The following is another embodiment of a server interface reuse method provided by the present invention.

[0040] A server is a CPU-centric computer system. Each server has a Baseboard Management Controller (BMC) that monitors its own system and underlying hardware. The normal operation of a server relies on data exchange between the interfaces on the server host and the interfaces on the BMC and the CPU. Since the BMC interfaces are used relatively infrequently—generally during installation, system updates, and power-on / off—data exchange between the BMC interfaces and the CPU occurs primarily between the interfaces on the server host and the CPU. The type of interface on the BMC is not uniquely defined. Currently, the most commonly used is the USB (Universal Serial Bus) interface, which is frequently used when the server host interacts with external devices. The CPU interface typically uses a PCIe interface supporting the PCIe (Peripheral Component Interconnect Express) protocol. However, some servers may use USB interfaces supporting other protocols, such as USB. In this embodiment, the server CPU uses a PCIe interface, the server host's first interface is a USB interface, and the BMC's processor connects to a second USB interface.

[0041] Figure 2 The diagram shown is a schematic representation of the USB interface multiplexing architecture of a server provided in an embodiment of the present invention. Figure 2As shown, the baseboard management controller integrates a USB switch (a type of interface converter) that supports USB interface connections. The USB switch implements three types of ports: a first port connected to several USB interfaces of the server host, a second port for data exchange with the server host's processor, and a third port for data exchange with the USB interface integrated on the baseboard management controller. The USB switch receives data from the server host's USB interface through the first port and sends it to the server host's processor through the second port for a first data exchange. When the baseboard management controller's processor receives an instruction to perform USB data exchange, the USB switch receives USB data sent from the USB interface integrated on the baseboard management controller through the third port and sends it to the server host's processor through the second port for a second data exchange. The number of first ports of the USB converter integrated on the baseboard management controller is no less than the number of USB interfaces of the server host, which typically has no more than four USB interfaces, used for a mouse, keyboard, USB storage devices, and security devices. The number of ports on the USB switch is greater than the sum of the number of USB interfaces of the server host and the number of USB interfaces integrated on the baseboard management controller.

[0042] Furthermore, an arbitration mechanism is built into the USB Switch, which can determine the priority of the USB interface of the server host and the USB interface of the BMC according to the order specified by the user for the first data exchange and the second data exchange. When the first port and the third port of the USB Switch receive data at the same time, the data received from the USB interface of the server host and the USB interface of the BMC can be sent to the processor of the server host through the second port respectively according to this priority, so that the first data exchange and the second data exchange can be performed in the order of this priority.

[0043] To address the trend of integrating PCIe interfaces instead of USB I / O (Input / Output) interfaces on server hosts, this embodiment preferably integrates a USB-PCIe conversion module in the baseboard management controller. By integrating the USB-PCIe conversion module between the second port of the USB switch and the processor of the server host, the data from the USB interface can be first converted into PCIe protocol data, and then sent to the PCIe interface of the server host processor through the interface bus of the baseboard management controller for data exchange with the server host processor.

[0044] Furthermore, a USB data exchange switch is integrated between the third port of the USB switch and the USB interface integrated on the baseboard management controller. The integrated USB interface is connected to the processor of the baseboard management controller via a bus. The third port of the USB switch can only receive USB data sent from the USB interface integrated on the baseboard management controller when the USB data exchange switch is turned on. This satisfies the USB interface needs of both the server host and the baseboard management controller while improving the management efficiency of the server's USB interfaces. It avoids managing unnecessary USB interfaces on the server host, avoids wasting interface resources, and improves the management efficiency of the server's interfaces.

[0045] A second aspect of the present invention provides a baseboard management control chip for server interface multiplexing. Figure 3 This diagram illustrates the structure of a server interface multiplexing baseboard management control chip according to an embodiment of the present invention.
