Evolution storage system and its evolution method

Abstract

An evoluating storage system is composed of a storage library consisting of running, standby and inhibiting storage pools, and a processor comprising storage service module, data I / O the distribution characteristics analyzing module, decision analysis module, storage device management module and user management module. According to the variation in environment and state of the storage system, it can choose the most propwer system organization scheme to the current environment to hold the dynamic balance of the system without dependency on the storage device.

Description

technical field [0001] The invention belongs to the technical field of data storage, and in particular relates to an evolutionary storage system and an evolutionary method thereof, that is, a technique for managing storage resources in a mass storage environment. Background technique [0002] The enterprise-level mass storage system used in the network environment faces the following challenges: the explosive growth of digital information, the increasing importance and security of data, a large number of user groups and multimedia applications have huge pressure on access performance, 24×7 The service requirements of the company require extremely high availability and maintainability. The main technologies to meet this challenge are high-performance disk arrays, network attached storage (NAS, NetworkAttached Storage), storage area network (SAN, Storage Area Network), iSCSI (internet SCSI) and storage management software. [0003] Although the above-mentioned technology is d...

Problems solved by technology

Therefore, with the advancement of technology, this system with stagnant performance will soon become obsolete, and users have to purchase new systems to meet the new requirements of applications;

[0005] Second, the current fixed data organization method makes the data distribution unsuitable for changes, and the overall performance of the system presents a tendency to degrade with use

Disk defragmentation on a single machine is very time-consuming, and the disk will not continue to be used during defragmentation, and it is more difficult to use the defragmentation program on the disk array;

[0006] Third, the organizational mode of the system structure is relatively fixed, which cannot adapt to the diversity and dynamics of applications

[0010] However, this technology only optimizes storage resources at the level of dynamic distribution of data according to the frequency of data usage by applications, so the effect is still very limited
