一种数据存储系统的研究

提出了一种新的数据存储系统——软件定义存储系统（SDS）的改进实施方案. 基于一种虚拟化的存储方式可以自动分配存储、安全、网络等资源，并将这些资源池化，从而实现数据保护、复制、压缩等一系列存储功能. 与传统的DAS和SAN系统的存储模式的存储性能进行了比较，结果表明该系统对于小容量的数据存储，存储速率略高其他存储方式；对大容量数据存储性能与吞吐量优化效果明显，当数据块容量达5 Tbit时，其存储速率超过SAN存储系统约3.9倍.

Study on a Data Storage System

This paper proposes a new data storage system named an improved implementation of Software Definition Storage System （SDS）， which can automatically allocate storage， security， network and other resources on basis of a virtualized storage mode. The system can also pool these resources to achieve data protection， replication， compression and other storage functions. By comparing storage performance of SDS with traditional Direct-Attached Storage and Storage Area Network （SAN） storage models， the storage rate of SDS is slightly higher than that of other storage systems for small-capacity data storage， and the SDS has obvious advantages in the storage performance and throughput optimization for large-capacity data storage. The storage rate of SDS is 3.9 times as much as that of SAN when the capacity amounts to 5 Tbits.
