Description

Server fan control system and method

The invention relates to the field of computers, and in particular to a server fan control system capable of saving resources and a method thereof.

With the rapid development of cloud computing and data centers, the demand for servers is also rapidly increasing. At present, the main heat dissipation method of the server in the design of the rack server is realized by the internal fan of each server. In general, when multiple servers need to be installed in a server rack, it is necessary to use a fan equal to the number of servers. For example, a basic 2U (Unit, a unit that represents the external dimensions of the server, 1U = 4.45cm) requires 4 servers, which requires 4 fans to work at the same time, and most of the fans installed inside the server consume power. Larger, it is not conducive to power saving, and because the fan is installed inside the server, heat dissipation and maintenance are also inconvenient.

The main object of the present invention is to provide a power saving server fan control system and method thereof.
