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

Embodiment Construction

[0027] Such as figure 1 As shown, the evolutionary storage system includes a storage library 2 , a processor 3 , a switch 5 and a bridge 6 . The processor 3 may be a single processor, SMP (Symmetric Multiple Processors, symmetric multiprocessor), MPP (Massively Parallel Processors, parallel processing system), cluster or other network computing devices. Processor 3 may be supported by multiple registered devices, such as computer node 1 registered in the evolutionary storage system, which may be a single processor, SMP, MPP, cluster or other network computing devices. The storage library 2 includes a plurality of physical storage devices 4, and if the storage devices support SCSI interfaces, each physical storage device 4 is connected to a SCSI (Small Computer Systems Interface) to FC (Fibre Channel, Fiber Channel) bridge 6 . Since the data transmission rate of the SCSI channel and the number of connected storage devices are limited, the storage devices can also use FC inter...

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 distributioncharacteristics 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...
