Embodiment Construction

[0029] Reference will now be made in detail to examples of the invention illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts.

[0030] The detailed description of the preferred examples of the invention can be better understood when read in conjunction with the accompanying drawings. It should be understood, however, that the invention is not limited to the precise arrangements and instrumentalities shown. Furthermore, it will be appreciated that for simplicity and clarity of illustration, components shown in the drawings have not necessarily been drawn to scale. For example, the dimensions of some of the components may be exaggerated relative to other components to clearly show details in the drawings.

[0031] In order to increase the storage capacity per unit volume and improve the competitiveness of the product, it is necessary to configure as many hard disks as po...

Abstract

The invention provides a method and system for fan control. The method includes the steps that a reliable temperature of each hard disk in operation is preset; a one-to-one corresponding relation between the average temperature of the hard disks and the rotating speed of a fan is established and stored and when the temperatures of the hard disks are higher than the reliable temperatures, a corresponding relation between the temperatures and the rotating speed of the fan is established and stored; actual temperatures of the multiple hard disks are read; the read actual temperatures of the multiple hard disks are sequentially compared with the preset reliable temperatures of the hard disks in operaiton, when no temperature of the hard disks is higher than the reliable temperatures of the hard disks in operaiton, the average temperature of the hard disks is calculated, the rotating speed, corresponding to the pre-stored average temperature, of the fan is found, and a control signal is output to the fan so that the rotating speed of the fan can be adjusted; when the temperature of one hard disk is higher than the corresponding reliable temperature of the hard disk in operation, the rotating speed, corresponding to the pre-stored temperature of the hard disk, of the fan is found, and a control signal is output to the fan so that the rotating speed of the fan can be adjusted. According to the method and system for fan control, reliability of the hard disks can be well improved, power consumption of the fan is reduced, and noise of the system is lowered.

Description

technical field [0001] The present invention relates to the technical field of large-capacity memory, in particular to the field of control of a fan for cooling the memory, specifically a fan control method and system. Background technique [0002] With the development of the network, the performance of the server as a network device is continuously improved, and as the network resources become more and more abundant, the requirements for the memory specially used for data storage are also continuously improved. In these servers, the storage is specially used as a device for network data storage. It is usually used together with the server because it needs to be installed on the rack together with the server. The appearance of the storage is very similar to that of the server. It has a chassis, and the front of the chassis has A front panel, of course, when the chassis is installed on the rack, the front is exposed at the front of the rack for user operation. The most impor...
