Problems solved by technology
In this process, the SMBUS link must have sufficient driving capability to ensure that the signal can be transmitted normally when reading the information of the PSU power supply. If the driving capability is insufficient, the data will be abnormal during the signal transmission process, and the normal power consumption cannot be achieved. monitor

The invention discloses a system management bus link, comprising: a motherboard chip, a first pull-up resistor and a second pull-up resistor; When any number of PSU power supplies less than or equal to the number threshold are configured on the bus link, the drive currents of the clock lines and data lines in the link are between 0.5 times the drive current threshold and 0.9 times the drive current threshold. The optimization of the pull-up resistors at the end reduces the impact of the number of PSU power supplies on the link on the drive capability, ensures the drive capability of the link, and improves link stability. In addition, the invention also discloses a method, device and equipment for determining the pull-up resistance of the system management bus link, which also have the above beneficial effects.
Description
technical field [0001] The invention relates to the technical field of data centers, in particular to a method, device and equipment for determining a system management bus link and its pull-up resistance. Background technique [0002] With the continuous development of science and technology, the era of big data, cloud computing and artificial intelligence based on the Internet has arrived. The amount of Internet data has increased dramatically, and the amount of calculation and frequency of calculation have increased accordingly, and the number of servers in the data center has also continued to increase. The total power consumption of each rack position in the data center is fixed. If the total power consumption limit is exceeded, the protection will be triggered, and the total power consumption also determines the number of servers that can be placed in a rack position. For a server, the overall power consumption information of the server is monitored in real time. Thi...
