Method and system for predicating self-adaptive disk array failure

Abstract

The invention discloses a method and a system for predicating self-adaptive disk array failure, which is characterized in that: based on a back-propagation neutral network, historical data of a parameter capable of characterizing the health state of disk array is collected by means of self-learning mechanism of the neutral network, so the rule characterizing the variation of the parameter along with time can be summarized by an approximation method, further predicating the value of the parameter. In the method, three parameter collecting policies from low level to high level, i.e. the first, second and third parameter collecting policies, are set in total, the number of the parameters increases gradually as the time granularity decreases gradually, and a universal calculation model for calculating the health state of disk array according to predicated parameter values and parameter failure thresholds are provided, therefore, the failure condition of disk array can be effectively predicated. The self-adaptive disk array failure predicating system comprises an information acquisition module, a self-adaptive configuration module, a data storage module, a self-adaptive index predication module, a parameter failure threshold module, a user management module and a user interface module.

Description

technical field [0001] The invention relates to the technical field of computer network management, in particular to a method and device for realizing a disk array fault prediction system. Background technique [0002] With the continuous use of large-scale computer information systems, massive data storage systems have been used more and more widely, the most important of which is RAID (Redundant Array of Independent Disks). RAID was originally proposed in his paper by Professor D.A.Patterson of the University of California, Berkeley. In this way, a storage subsystem with super large capacity, fast response speed and high reliability is formed. [0003] Through the data block technology and redundancy mechanism, the disk array system has a certain data reliability guarantee, but this guarantee mechanism is limited: the disk array specific to a certain business system often uses the same model with similar quality consistency And batches of disks, after long-term use, when...

Problems solved by technology

The alarm is often issued when the fault parameter exceeds the threshold, but there is no prediction or poor prediction accuracy for when the fault parameter will exceed the threshold, and when the fault parameter exceeds the threshold, it is likely that the time before the actual disk failure has occurred Very short, not conducive to the preparation of spare parts in advance
