技术领域Technical Field

本发明涉及设备管理技术领域，具体涉及硬件设备管理方法、装置、BMC、存储介质及程序产品。The present invention relates to the technical field of equipment management, and in particular to a hardware equipment management method, device, BMC, storage medium and program product.

背景技术Background technique

PCIE(Peripheral Component Interconnect Express)在服务器应用中扮演着重要的角色。PCIE是一种高速串行总线标准，用于连接计算机内部的各种硬件设备，如显卡、网卡、存储控制器等。PCIE在服务器应用中起到了连接和扩展各种硬件设备的关键作用，提供了高速、可靠的数据传输通道，满足了服务器对性能和扩展性的需求。PCIE (Peripheral Component Interconnect Express) plays an important role in server applications. PCIE is a high-speed serial bus standard used to connect various hardware devices inside the computer, such as graphics cards, network cards, storage controllers, etc. PCIE plays a key role in connecting and expanding various hardware devices in server applications, providing a high-speed and reliable data transmission channel to meet the server's performance and scalability requirements.

为了更好的监视和控制这些网卡，网卡设备往往提供了带内、带外等管理方式。BMC就是通过带外方式管理PCIe接口卡类的设备的。槽网卡物理连接是插接在存储设备的riser卡上的PCIe接口里，PCIe接口中有smbus连线与网卡相连，BMC通过I2C switch器件与riser卡相连，riser卡再通过I2C switch器件，与网卡相连。如图1所示，为网卡的连接方式。In order to better monitor and control these network cards, network card devices often provide in-band and out-of-band management methods. BMC manages PCIe interface card devices in an out-of-band manner. The physical connection of the slot network card is plugged into the PCIe interface on the riser card of the storage device. The PCIe interface has an SMBus connection connected to the network card. The BMC is connected to the riser card through the I2C switch device, and the riser card is connected to the network card through the I2C switch device. As shown in Figure 1, this is the connection method of the network card.

BMC在管理网卡时，通常需要人工将网卡的连接方式以表格的形式输入至BMC中，BMC根据用户输入的表格，确定网卡的连接方式，然后对网卡进行管理。但是，当网卡的连接方式发生变化，BMC无法通过切换I2C链路正确找到与BMC连接的硬件设备，从而造成BMC对PCIe接口卡设备无法识别、监控。When BMC manages the network card, it is usually necessary to manually input the connection mode of the network card into the BMC in the form of a table. BMC determines the connection mode of the network card based on the table entered by the user, and then manages the network card. However, when the connection mode of the network card changes, BMC cannot correctly find the hardware device connected to BMC by switching the I2C link, resulting in BMC being unable to identify and monitor the PCIe interface card device.

发明内容Summary of the invention

有鉴于此，本发明提供了一种硬件设备管理方法、装置、BMC、存储介质及程序产品，以解决当网卡的连接方式发生变化，BMC无法通过切换I2C链路正确找到与BMC连接的硬件设备，从而造成BMC对PCIe接口卡设备无法识别、监控的问题。In view of this, the present invention provides a hardware device management method, apparatus, BMC, storage medium and program product to solve the problem that when the connection mode of the network card changes, the BMC cannot correctly find the hardware device connected to the BMC by switching the I2C link, thereby causing the BMC to be unable to identify and monitor the PCIe interface card device.

PCIE(Peripheral Component Interconnect Express)在服务器应用中扮演着重要的角色。PCIE是一种高速串行总线标准，用于连接计算机内部的各种硬件设备，如显卡、网卡、存储控制器等。在服务器领域，PCIE被广泛应用于以下几个方面：PCIE (Peripheral Component Interconnect Express) plays an important role in server applications. PCIE is a high-speed serial bus standard used to connect various hardware devices inside the computer, such as graphics cards, network cards, storage controllers, etc. In the server field, PCIE is widely used in the following aspects:

(1)扩展插槽：服务器通常需要支持多个扩展卡，如网络适配器、存储控制器、加密卡等。PCIE提供了高带宽和低延迟的连接方式，可以满足服务器对各种扩展卡的需求。(1) Expansion slots: Servers usually need to support multiple expansion cards, such as network adapters, storage controllers, encryption cards, etc. PCIE provides a high-bandwidth and low-latency connection method to meet the server's needs for various expansion cards.

(2)存储和加速卡：随着数据量的不断增长，服务器对存储容量和速度的要求也越来越高。PCIE接口可以连接高速固态硬盘(SSD)和闪存卡等存储设备，实现快速的数据传输。此外，PCIE还可以连接加速卡，如图像处理器、加密解密卡等，提升服务器的计算和处理能力。(2) Storage and acceleration cards: As the amount of data continues to grow, servers have higher and higher requirements for storage capacity and speed. The PCIE interface can connect to storage devices such as high-speed solid-state drives (SSDs) and flash cards to achieve fast data transmission. In addition, PCIE can also connect to acceleration cards such as image processors and encryption and decryption cards to improve the computing and processing capabilities of the server.

(3)GPU加速：在大规模数据处理和科学计算领域，服务器常常需要使用图形处理器(GPU)进行并行计算。PCIE接口为GPU提供了高带宽和低延迟的连接通道，实现与主处理器的协同工作，提升计算性能。(3) GPU acceleration: In the field of large-scale data processing and scientific computing, servers often need to use graphics processing units (GPUs) for parallel computing. The PCIE interface provides a high-bandwidth and low-latency connection channel for the GPU, enabling it to work in coordination with the main processor and improve computing performance.

PCIE在服务器应用中起到了连接和扩展各种硬件设备的关键作用，提供了高速、可靠的数据传输通道，满足了服务器对性能和扩展性的需求。PCIE plays a key role in connecting and expanding various hardware devices in server applications, providing a high-speed, reliable data transmission channel and meeting the server's requirements for performance and scalability.

例如在云存储时代，海量数据传输需要占用超大的带宽，更需要用到大量的高性能的网卡设备。为了更好的监视和控制这些网卡，网卡设备往往提供了带内、带外等管理方式，如支持ncsi over mctp over smbus的功能以供带外管理，支持ncsi over rmii的功能以供带内管理，通过NSCI命令对网卡进行查询和配置。BMC就是通过带外方式管理PCIe接口卡类的设备的。For example, in the era of cloud storage, massive data transmission requires a large bandwidth, and a large number of high-performance network card devices are needed. In order to better monitor and control these network cards, network card devices often provide in-band and out-of-band management methods, such as supporting ncsi over mctp over smbus for out-of-band management, supporting ncsi over rmii for in-band management, and querying and configuring network cards through NSCI commands. BMC manages PCIe interface card devices in an out-of-band manner.

如图1所示，为网卡的连接方式。槽网卡物理连接是插接在存储设备的riser卡上的PCIe接口里，PCIe接口中有smbus连线与网卡相连，BMC通过I2C switch器件与riser卡相连，riser卡再通过I2C switch器件，与网卡相连。As shown in Figure 1, this is the connection method of the network card. The physical connection of the slot network card is plugged into the PCIe interface on the riser card of the storage device. The PCIe interface has an SMBus connection connected to the network card, the BMC is connected to the riser card through the I2C switch device, and the riser card is connected to the network card through the I2C switch device.

当前采取的方式是BMC获取BIOS发送的PCIe设备信息，得到一个PCIe设备信息的列表，内含PCIe设备VendorID、DeviceID、PCIE_unique_id等信息。BMC则根据PCIE_unique_id在内部代码中查表获取带外访问网卡信息的I2C通路进行访问，并尝试读信息，读取返回正确即认为网卡存在。The current method is that BMC obtains the PCIe device information sent by BIOS and obtains a list of PCIe device information, including PCIe device VendorID, DeviceID, PCIE_unique_id, etc. BMC then looks up the table in the internal code based on PCIE_unique_id to obtain the I2C channel for out-of-band access to the network card information and tries to read the information. If the read returns correct, it is considered that the network card exists.

但是在实际应用过程中，BMC对于卡的识别的所有操作都是内化到程序中的，只要电路、接线、器件(比如riser卡)发生了变化，都有可能使原有的映射关系发生变化，导致BMC无法通过切换I2C链路正确找到PCIe接口卡设备，从而造成BMC对PCIe接口卡设备无法识别、监控。However, in actual application, all operations of BMC for card identification are internalized into the program. As long as the circuit, wiring, and devices (such as riser card) change, the original mapping relationship may change, resulting in the BMC being unable to correctly find the PCIe interface card device by switching the I2C link, resulting in the BMC being unable to identify and monitor the PCIe interface card device.

其中，硬件设备的标识信息可以包括：硬件设备对应的VendorID、PCIE_device_id、Riser_type、PCIE_mark_id等标识信息。其中，Vendor ID是一个由PCI-SIG(PCISpecial Interest Group)分配给硬件制造商的16位标识符。它用于唯一地标识硬件设备的制造商。每个厂商都有自己独特的Vendor ID。PCIE_device_id是由硬件设备制造商分配的16位标识符，用于唯一地标识硬件设备本身。相同厂商的不同设备将具有不同的PCIE_device_id。Riser_type是PCIe硬件设备插在机器上槽座部件，它对I2C switch切换地址有影响，不同的riser卡其I2C switch bus的排列顺序不一样。PCIE_mark_id是硬件设备在机箱的丝印。Among them, the identification information of the hardware device may include: the identification information such as the VendorID, PCIE_device_id, Riser_type, PCIE_mark_id corresponding to the hardware device. Among them, the Vendor ID is a 16-bit identifier assigned to the hardware manufacturer by the PCI-SIG (PCI Special Interest Group). It is used to uniquely identify the manufacturer of the hardware device. Each manufacturer has its own unique Vendor ID.
