Abstract

The invention discloses a method and a system for layer-management of a storage system. The method includes the following steps that according to medium types of storage media in the storage system, each storage medium is divided into at least two storage layers; according to data types of data objects, the data objects are stored in corresponding storage layers. By means of layer data storage, the method and the system are applied to a distributed file system, automatic layer storage of data and automatic migration of data are supported, data storage cost can be greatly reduced, and storage efficiency is improved. Meanwhile, data can be managed reasonably, and the method and the system have the advantages of good controllability and expandability.

Description

technical field [0001] The invention relates to storage management of distributed files, in particular to a method and system for hierarchical management of a storage system. Background technique [0002] Today, unstructured data is growing faster and faster, and this trend will only increase over time. According to market research and analysis, unstructured data has grown faster than all other types of data. [0003] Structured data, such as CRM, ERP, financial, etc. are growing in a smooth manner. Unstructured data, such as Emails, spreadsheets, files and their folders, etc., account for 50%-100% of an enterprise's data growth. [0004] Considering that the industry's budget has not increased or even decreased, the demand for storage solutions for intelligent management of data is becoming more and more urgent. To analyze a data object in the storage system, it may be frequently accessed when it first enters the system, but when the data is old or no longer updated, it ...
