Embodiment Construction

[0022] Refer to the attached figure 2 , the content of the present invention is described with a specific example to realize the process of this method.

[0023] As described in the summary of the invention, the architecture of the present invention mainly includes: a disk I / O analysis unit (1), a policy generation unit (2), an operating system disk sleep interface (3), and an operating system timing task (4).

[0024] Among them, the disk I / O analysis unit (1) collects the read and write conditions of the disk for a long time, analyzes and organizes the collected disk read and write conditions, and provides the analysis and sorting results to the strategy generation unit (2), the strategy The generating unit (2) generates the disk dormancy policy (that is, during which time period the disk is in the dormant state) according to the results of the disk I / O analyzed and organized by the disk I / O analysis unit (1), and converts the policy into an operating system Timing tasks (...

Abstract

The invention provides a computer energy conservation method based on magnetic disc dormancy. A systematic structure comprises a magnetic disc input / output (I / O) analytical unit (1), a strategy generating unit (2), an operating system timed task (3) and an operating system disc dormancy port (4). An operating system provides the functions of the disc dormancy port and a timer and controls a magnetic disc with low frequency to be in a dormancy state through statistic analysis on the magnetic disc read-write frequency for a period of time, so that aims of prolonging service life of the computer magnetic disc and reducing energy consumption of the computer are achieved.

Description

technical field [0001] The invention relates to the field of computer energy saving, in particular to a computer energy saving method based on disk dormancy. Background technique [0002] While the overall computing power of the computer is advancing by leaps and bounds, a problem that attracts users' attention is also coming. How to effectively reduce the power consumption of the computer, so as to reduce the overall energy consumption of the overall data center is a problem that is placed in front of the data center administrator. problem. [0003] At present, the vast majority of computer manufacturers' solutions are mostly using virtualization, cloud computing resource scheduling and other technical means to save data center energy consumption by improving resource utilization and shutting down computers when the overall load is low. This kind of solution can also effectively reduce Data center energy consumption, saving maintenance costs. But it ignores the power cons...
