Embodiment Construction

[0047] In order to pursue the goal of high density of storage servers, the hard disk uses smaller platters and read heads, and selects high-performance fans to improve heat dissipation; however, the high-frequency noise of high-performance fans has become one of the bottlenecks hindering the performance of hard disks. High-density storage and high-performance fans are two sides of the same coin, because the storage server will carry a variety of different types of hard disks and fans. The performance or life of the hard disk due to random vibrations conducted by air is degraded. Because the sound will be transmitted in all directions, that is, the vibration conducted by the air is not easy to determine the direction of the noise. Noise reduction at frequencies recognizable to the human ear can no longer meet the needs of existing high-density storage. First of all, the main noise orientation is explored by the noise source diagnostic device, the noise processing device is installe...

Abstract

The invention belongs to the technical field of server noise processing, and particularly provides a regulation and control system and method for random vibration in a server, and the system comprises a noise processing device and a plurality of noise source diagnosis devices. The noise source diagnosis device is installed at the position of a hard disk in the server and used for capturing noise generated in the server. The noise source diagnosis device is further connected with a data recorder, and the data recorder is used for reading the noise captured by the noise source diagnosis device, judging the direction where the noise is generated and outputting direction information. A noise processing device is installed at the position of a corresponding part of the server according to the output azimuth information, and the noise processing device is used for obtaining original noise of the position, carrying out processing conversion and calculation on the obtained original noise and outputting sounds with opposite phases and the same amplitude to offset the original noise. The noise processing device is used for reducing noise for frequency bands influencing hard disk performance, and the use performance and service life of the hard disk are improved.

Description

Technical field [0001] The present invention relates to the field of server noise processing technology, specifically to a random vibration regulation system in the server, a method. Background [0002] In order to pursue the goal of high density of storage servers, the hard disk uses smaller platters and read heads, and selects high-performance fans to improve heat dissipation; however, the high-frequency noise of high-performance fans has become one of the bottlenecks hindering the performance of hard disks. [0003] High-density storage and high-performance fans are two sides of the same coin, because the storage server will carry a variety of different types of hard disks and fans. The performance or life of the hard disk due to random vibrations conducted by air is degraded. [0004] Because the sound will be transmitted in all directions, that is, the vibration conducted by the air is not easy to determine the direction of the noise. Noise reduction at frequencies recogniza...
