Linux下高效存储优化的研究

随着数据的指数性增长,存储技术成为信息产业发展的核心动力,存储系统在一定程度上比计算系统和通信系统更加重要。如何高效地存储和优化存储空间,是存储系统急需解决的问题。本文介绍高效存储技术中的RAID技术、重复数据删除技术、数据压缩技术等,并在Linux环境下设计与实现具有高效存储优化特点的应用程序。试验表明该应用程序实现了软件RAID,删除了重复性数据,提高了存储空间利用率,降低了存储能耗。

Research on Efficient Storage Optimization of Linux

With the exponential growth of data, storage technology becomes the core driving force of development of information industry, the storage system to some extent, is more important than computing and communication systems. The urgent problem of storage system is how to efficiently store data. The article describes the efficient storage technology RAID technology, data de-duplication technology, data compression technology, designs and realizes an application of efficient storage optimization characteristics in a LimLx environment. Tile experiments show that this application realizes software RAID, removes repetitive data, improves the space utilization of the storage system, reduces storage energy consumption.
