Abstract

The invention provides a method and device for fan speed adjusting and a blade server. The blade server comprises at least one server one board, at least one cooling fan and a case management module;the method is characterized by including the steps that a one board PWM duty ratio sent by a one board management controller of each server one board is received, and according to the received one board PWM duty ratio, a first PWM duty ratio is determined; a second PWM duty ratio and detected signals sent by the case management module simultaneously are received; when no detected signals are received, the first PWM duty ratio is sent to the cooling fan, and when the detected signals are received again, the second PWM duty ratio is sent to the cooling fan. By means of the method, the device andthe blade server, under the condition that the case management module fails, the rotation speed of the cooling fan can be adjusted and controlled, so that safe and reliable heat dissipation of a system is better guaranteed.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a fan speed regulation method, device and blade server. Background technique [0002] In the blade server system, in order to ensure the stable and efficient performance of each node of the system, the system is required to have a good working environment temperature. Therefore, a good heat dissipation solution has become an important factor that must be considered in the design of the blade server. The current heat dissipation solution usually uses a chassis management module (Chassis Management Module, CMM) to detect the temperature collected by the temperature sensor of each server board to dynamically adjust the fan speed. [0003] In the process of realizing the present invention, the inventor found that there are at least the following technical problems in the prior art: [0004] If the chassis management module (Chassis Management Module, CMM) fails, the fan will lose ...
