Cabinet server and control method thereof

Abstract

The invention relates to the technical field of IT and discloses a cabinet server and a control method of the cabinet server. The cabinet server comprises a cabinet, a rotating speed acquisition device, a temperature acquisition device and a controller. Multiple separation boards are arranged in the cabinet so that multiple air ducts can be formed, and each air duct is internally provided with a fan; the air ducts are arranged in at least one air duct set, each air duct set comprises one convertible air duct and two side air ducts; air outlets of the convertible air ducts are provided with air outlet baffles; the separation boards between the side air ducts and the convertible air ducts are provided with ventilation openings and ventilation opening baffles; the controller is in signal connection with the rotating speed acquisition device and the temperature acquisition device and can control the rotating speed of the fans in the convertible air ducts and the rotating speed of the fans in the side air ducts according to information acquired by the rotating speed acquisition device and the temperature acquisition device, so that the ventilation openings are controlled to be opened or closed through the ventilation opening baffles. When the heat dissipation condition is met, the noise of the fans is the lowest when the cabinet server works.

Description

technical field [0001] The invention relates to the field of IT technology, in particular to a cabinet server and a control method thereof. Background technique [0002] At present, the degree of modularization between functional devices in rack servers in the IT technical field is getting higher and higher. [0003] Modularization refers to the combination of some functional devices to form a combination with independent functions. Each module is used to complete a specific sub-function. All modules are assembled in a certain way to become a whole, and then complete the entire cabinet server. The functions required by the internal system. The modular design has the advantages of easy maintenance and system upgrade. The cabinet of the cabinet server is provided with partitions to separate the modules into partitions and form air ducts corresponding to the above modules one by one. [0004] In order to solve the heat dissipation problem of the rack server, a fan is used in...

AI Technical Summary

Problems solved by technology

[0005] In the rack server, the resistance of the functional modules in each air duct is different, and the air volume required for heat dissipation by the functional modules in each air duct is also different; The fan speed in the air duct with large air volume required for module heat dissipation is high, and it is prone to failure. When a fan in an air duct fails, the entire cabinet server will not work. Fans need to be backed up by 1+1, resulting in too many fans in the cabinet server. The fan noise is loud when the server is working

When the fan in the cabinet server adopts the above-mentioned method 2 design, the fans in the cabinet are gathered together. When a fan fails, the air volume loss caused by the failed fan can only be increased by increasing the speed of the adjacent fan. However, in order to meet the The air volume demand of the air duct with the largest air volume demand and the largest resistance of the functional modules requires the speed of all fans to be increased, which leads to the problem of excess air volume in the assembly area with low resistance and easy heat dissipation, and all fans are maintained at a higher speed When the cabinet server is working, the noise is also very high
