Problems solved by technology

[0003] The current heat dissipation design for server multi-node systems can only take into account the overall or constant mode, that is, all nodes are taken into consideration. When the overall power is low, the fan speed is reduced, or the fan is fixed at a high speed of 80% and remains constant; the same fan is Multiple server nodes provide cooling air volume, and the unbalanc

Example Embodiment

[0019] In the following, a detailed description of a fan intelligent control method of the present invention will be given with reference to the accompanying drawings.

[0020] The invention is based on the support point of control theory, and specifically uses a high-efficiency and low-ripple power supply design method to solve the problem that the output efficiency and ripple of the power supply cannot be balanced during the operation of the server motherboard. Now take three server nodes as an example, as attached figure 1 As shown, a fan intelligent control method is now provided, and the specific control process is:

[0021] Step 1. First obtain the height dimension of a single fan structure, and divide the server nodes into regions according to the height dimension of the fan structure. Generally, the height dimension of a single fan is 12cm, and the server thickness is 4.45cm (1U). Three server nodes (corresponding to the height of 3U) as a group; the above division belongs...

Abstract

The invention provides a method for intelligently regulating and controlling a fan. The method specifically includes;firstly, acquiring height size of a single fan structure, and regionalizing server nodes according to the height size of the fan structure; acquiring temperature condition of the server nodes in groups; outputting PWM (pulse-width modulation) signals for regulating and controlling the rotating speed of the fan by the nodes according to above temperature condition; comparing and judging PWM duty ratios; and switching to the high PWM duty ratio for controlling the fan. Compared with the prior art, the method has the advantages that high efficiency and low noise of regulation and controlling of multiple server nodes are guaranteed, intelligence of fan regulation and controlling is achieved, and the method is higher in reliability and stability.

Description

technical field [0001] The invention relates to the technical field of computer communication, in particular to a high-efficiency and low-noise fan intelligent control method that ensures multi-server node control. Background technique [0002] In today's server system, it is more and more common to adopt the topology of multi-node cluster distribution, that is, multiple server nodes are gathered together to form a server cluster. The computing tasks of the server cluster are getting higher and higher, and its ability to respond to external cooling is getting better Fast, while completing high-performance calculations with large amounts of data, higher requirements are put forward for the peripheral fan control design. Fan control needs to take into account real-time response capability, power consumption, and noise control; the real-time response capability of fan control is required. When the temperature of the server node rises rapidly, the fan can be controlled to speed ...
