Description

Technical Field

[0001] The utility model belongs to the technical field of servers, and in particular relates to a server communication device. Background Art

[0002] For the management of server hardware equipment in modern data centers, the system often uses the whole cabinet management method due to the limited space in the computer room. The host computer enters the management interface of the hardware equipment through a local connection to centrally control it. For high-density server hardware equipment, the cabinet must provide sufficient cable channels. As the configuration of the equipment in the cabinet changes, the cables must also be increased or decreased.

[0003] There are currently two main solutions for communication between servers and between servers and host computers: integrating more different types of interfaces on the motherboard, such as USB, Ethernet, and Uart interfaces; using various adapters and plug-in cards, such as OCP network cards or PCIe network cards, to achieve communication between servers or between servers and host computers through Ethernet.

[0004] The existing technical solutions have the following problems:

[0005] (1) The cable connection of the entire cabinet will take up a lot of space, the system wiring will be complicated, which will affect the installation and maintenance of the equipment and greatly limit the expansion capability of the system.

[0006] (2) For equipment management and maintenance, the host computer uses local connection to manage hardware devices, which requires additional network hardware support and reduces management efficiency when there are a large number of devices or they are geographically dispersed.

[0007] (3) Integrating more different types of interfaces on the motherboard will take up a lot of space on the motherboard, which increases production costs and design difficulty, and also limits the development of other functional modules. In traditional hardware design, data communication mainly relies on Ethernet network interfaces or serial ports. Although the design of these interfaces is very mature, their bandwidth and speed are limited, and it is difficult to meet all requirements for high-speed, large-data application environments.

[0008] (4) In addition to expanding the PCIe interface on the motherboard, using OCP network cards and PCIe network cards also requires additional cables and accessories as well as installation and configuration work. In large-scale deployments, this workload will increase significantly, seriously affecting the installation efficiency and operation and maintenance efficiency of the equipment.

[0009] (5) The interaction between the host computer and the server can generally only be processed according to the preset program. If the preset program has defects or the customer has additional customization requirements, the development cycle is often long and the development difficulty is greater. Utility Model Content

The USB connector is a USBTYPE A interface, which can be connected to a PC for device debugging and management. By connecting the NB-IoT module via the USB interface, communication with the IoT platform can be achieved.

[0045] The PCIe standard card includes a field replaceable unit (FRU) and a temperature sensor (Sensor). The field replaceable unit and the temperature sensor are connected to the BMC on the mainboard through a low-speed communication bus (SMBUS); the board supports the BMC to read the board FRU information and the temperature information collected by the sensor through I2C. Among them, the low-speed communication bus (SMBUS) can use the I2C bus, and the I2C interface of the BMC is connected to the adapter card through the I2C bus, thereby establishing an I2C communication connection with the field replaceable unit (FRU) and the temperature sensor (Sensor) of the PCIe standard card.

[0046] The PCIe card is also connected to an I2C expansion card (I2C Expander) so that the card can be connected to other I2C devices.
