新型硬盘用于重复数据删除技术

The Research of Inline-process Deduplication Basic in Solid State Drives

随着信息全球化的快速发展,数字信息量成指数级增长,这给数据存储空间和高带宽网络传输需求带来严峻的挑战.重复数据删除技术可透过重复删除计算,去除数据冗余,大幅度缩减占用的存储空间,提高网络传输速率.本文首先介绍重复数据删除技术的概念、基本原理跟应用;以及介绍在线处理重复数据删除的优缺点跟相应的改进;最后介绍固态硬盘概念跟基本原理,以及利用固态硬盘提高在线处理重复数据删除的存取速度.

With the rapid development of global information,exponential growth of digital information make a difficult challenge for data storage and high-bandwidth network transmission.The deduplication can remove redundancy data and reduce storage space substantially.In this paper,firstly,we will introduce the concept,basic theory,and application of deduplication and then introduce the advantages and disadvantages of inline-process deduplication,and what have done to improve.At last,we describe the concepts and basic theory of solid state drives and using solid state drives to improve the access of inline-process deduplication.
