Magnetic disk health information optimal management method and device

Abstract

The invention relates to a magnetic disk health information optimal management method, and belongs to the technical field of computer storage. The method comprises the following steps: providing monitoring strategies for magnetic disks with different power-on time according to a correlation algorithm of a magnetic disk life cycle and a failure rate; according to the monitoring strategies, periodically monitoring, and acquiring the attribute values, reflecting the health conditions, of the bottom layers of the magnetic disks; storing the magnetic disk health data in a two-stage database manner, and reducing the magnetic disk access times; directly reflecting the main memory database to a graphical interface to allow a user to detect directly; integrating the data in the backstage by the bottom layer database, judging the failure, and accessing an alarm mechanism. Compared with the prior art, the magnetic disk health information optimal management method disclosed by the invention is to set up the monitoring strategies according to the magnetic disk using time, so as to reduce unnecessary load caused by frequent monitoring; the health information is stored in different stages, so as to greatly save the storage space and the extra I / O (Input / Output) times; the monitoring management platform provides the graphic monitoring mechanism to display the health information more directly; the data exporting mechanism is provided to bring convenience for analyzing the historical data.

Description

technical field [0001] The invention relates to a disk health information optimization management method throughout the disk life cycle, belonging to the technical field of computer storage. Background technique [0002] With the continuous development of information technology and the increasing amount of data, the reliability and security of storage systems have become a topic of common concern in the industry. This topic has derived a series of research on disk health management mechanisms, fault warning and processing mechanisms. [0003] GOOGLE released Failure Trends at the FAST (File and Storage Technologies) conference in 2007 on the basis of nine months of monitoring analysis and tracking research on 100,000 different types of disks produced by nine manufacturers in its data center. In a Large Disk Drive Population paper, it puts forward conclusions related to the five aspects of disk mean time between failures, the role of disk self-health management technology, di...
