Description

Control circuit board, micro server, control system and control method thereof

The present invention relates to a control circuit board, a microserver, a control system, and a control method thereof, and more particularly to a control circuit board, a microserver, a control system, and a control method thereof applied to an integrated circuit bus bar.

The integrated circuit bus I2C (Inter-Integrated Circuit) bus is a common serial communication bus. It was developed in the 1980s by Philips to connect the host to the microserver and peripherals. The devices on the I2C serial communication are mainly presented in a master-slave architecture, that is, with a master device and a slave device (Slave). Both the master device and the slave device can perform data transmission and reception. In the current system design, a master device can be connected to multiple slave devices, such as a baseboard management controller. Each slave device has its own different address, and the master device must communicate with different slave devices through these different addresses. The address is written to the slave device, and each of the different addresses has its own corresponding firmware version. That is to say, the greater the number of slave devices, the greater the number of addresses that need to be written to the slave devices. In contrast, the number of firmware versions required is also greater. For example, one master device is connected to 20 slave devices, in which case the 20 slave devices require 20 different addresses. That is, 20 different firmware versions are required, which will increase the development cost of hardware and software.

In other words, the first processor 122 can selectively turn on the first switching component 121 to the microserver to be accessed by the master device 110 according to the first control command generated by the processing result of the first general-purpose input/output signal. The data path of the node is calculated, and the master device 110 performs data transmission with the micro-server computing node to be accessed.

In an embodiment, after the first processor 122 turns on the first switching element 121 to be turned on to the micro-server computing node to be accessed by the main control device 110, the first processor 122 further transmits the second universal through the electrical path.

When the second processor 220A of the microserver computing node 200A receives the second general purpose input and output signal, the second processor 220 processes the second general purpose input and output signals. The second processor 220 identifies the substrate management controller 230A through the code included in the processing result of the second general-purpose input/output signal, thereby generating a second control command. This code is associated with the baseboard management controller 230 of the microserver computing node 200A. At this time, the second processor 220A switches the switch in the second switching element 210A to the substrate management controller 230A according to the generated second control instruction to turn on the data path of the second switching element 210A to the substrate management controller 230A. At this time, the master device 110 can perform data transfer with the substrate management controller 230A on the microserver computing node 200A.

In another example, assume that the master device 110 is to access the substrate management controller 240B on the microserver computing node 200B, and the first processor 122 turns on the microserver computing node 200B. The first processor 122 further transmits a second general purpose input and output signal to the microserver computing node 200B via an electrical path. When the second processor 220B of the microserver computing node 200B receives the second general purpose input and output signal, the second processor 220B processes the second general purpose input and output signal. The second processor 220B recognizes the substrate management controller 240B through the code included in the processing result of the second general-purpose input/output signal, thereby generating a second control command. This code is associated with the baseboard management controller 240B of the microserver computing node 200B. At this time, the second processor 220B switches the switch in the second switching element 210B to the substrate management controller 240B according to the generated second control instruction to turn on the data path of the second switching element 210B to the substrate management controller 240B.
