Design method for optimizing hard disk management

Abstract

The invention discloses a design method for optimizing hard disk management. The method comprises the following steps: sending a hard disk management signal, entering a CPLD (complex programmable logic device), and parsing the hard disk management signal, wherein the hard disk management signal is an SGPIO (serial general purpose input output) signal; after the signal is parsed, monitoring, by the CPLD, the state of a hard disk by virtue of three state indicator lamps for a control state, wherein the SGPIO signal includes four signal wires: SCLOCK, SLOAD, SDOUT and SDIN; in order to guarantee the quality of the management signal, filtering burrs in the signal, and synchronizing the SCLOCK signal by adopting a clock with the frequency of 25MHz in the CPLD. Compared with the prior art, the hard disk management scheme can be optimized without changing the circuit of hardware; by optimizing a code, while the chip resource is sufficiently utilized, the optimization when the hard disk management signal is parsed is realized, an effect for filtering a high-frequency component is realized, and the hard disk management signal quality is further improved; by virtue of the optimized design of the code, the universality of a hard disk backboard is improved, and the practicability is high.

Description

technical field [0001] The invention relates to the technical field of computer servers, in particular to a design method with strong practicability and optimized hard disk management. Background technique [0002] With the development of cloud computing and big data, many fields have begun to migrate traditional business to the cloud. With the increase of business volume, the amount of data storage and processing in the server system is also increasing. The number of hard disks in the system also increases accordingly. Usually, the storage subsystem is responsible for storing data and reading and writing data during the operation of the server. For today's big data era, the role of the hard disk is self-evident. The working status of the hard disk directly determines the stability of the system. . [0003] The working status of the hard disk is reflected by three LED indicators, which are active (green), locate (blue), and error (red). The signals that control the three ...

Problems solved by technology

[0004] However, in the actual working process, due to the impedance mismatch or the interference of the external electromagnetic environment, sometimes a "return groove" will be generated on the rising edge of the SCLOCK signal, which will cause misanalysis during the analysis, and then cause the hard disk to fail. An exception occurred in the management of the state
