面向下一代数据中心的软件定义存储技术研究

Research on Software Defined Storage Technology for the Next-Generation Data Center

随着互联网技术的快速发展,数据的爆炸式增长,存储系统的软硬件紧耦合设计严重地限制了存储技术的发展,也越来越无法满足移动互联网和大数据时代下,对存储系统快速、多变的需求。软件定义存储(SDS)作为一种新的存储系统架构,更适合下一代数据中心的发展。从SDS的定义出发,对SDS的研究现状进行阐述,结合应用对SDS的需求,提出了SDS的参考架构,并给出了SDS的演进思路。

With the rapid development of internet technology and the explosive growth of data, the storage system tightly coupled hardware and software design is limiting the development of storage technology severely, and unable to meet the rapidly changing needs in the mobile internet and big data era increasingly. Software defined storage as a new storage system architecture is more suitable for the development of the next-generation data centers. The SDS research status was described, started from the definition of SDS, and then SDS reference architecture combined with the SDS system requirements was proposed, finally the evolution of ideas were put forward.
