Problems solved by technology

On the one hand, a server system may have many different configuration states, and different configuration states have different heat dissipation requirements, so multiple different fan speed control tables are required to meet different heat dissipation requirements, and these Fan speed control tables are usually stored in the memory of the baseboard management controller. The more fan speed control tables, the larger the memory occupied, which will increase the operating burden of the baseboard management controller.
On the other hand, the format of the fan speed control table in the baseboard management controller is binary code, which can only be compiled and read by professional programmers of the baseboard management controller. Therefore, the cooling engineer who provides the fan control parameters cannot independently modify and Updating the fan speed control table must rely on professional programmers

Abstract

The invention relates to a method for controlling the rotating speed of a fan by utilizing a baseboard management controller, applied to a server system with the baseboard management controller. The server system has various configuration states and is provided with a plurality of fans for cooling; the baseboard management controller comprises firmware and a memory, and a plurality of first fan speed control tables in document formats, which respectively correspond to one of the configuration states, are provided so that a cooling engineer can freely edit and update the contents of the first fan speed control tables without relying on special programming staff. In addition, a second fan speed control table corresponding to the configuration state of the server system of the baseboard management controller only is loaded into the memory so as to reduce the memory space, of the memory, occupied by the second fan speed control table and lighten the operation load of the baseboard management controller.

Description

technical field [0001] The present invention relates to a method for controlling the rotational speed of a fan, and more specifically, relates to a method for controlling the rotational speed of a fan by using a baseboard management controller. Background technique [0002] Usually, in a server system, multiple fans are used for heat dissipation, and the speed of the fans is usually controlled by a baseboard management controller (BMC, Baseboard Management Controller) in the server system. Since the heat generated by the server system is different under different operating states or hardware configurations, the server system usually needs to control the speed of these fans according to its operating state or hardware configuration to achieve effective heat dissipation, thereby improving the performance of the server system. For this purpose, a fan speed control table is usually established in the baseboard management controller to control the speed of each fan according to t...
