| 摘 要： | 传统的磁盘阵列一般采用集中式控制结构，其连接的底层磁盘数受系统总线的制约，容易出现性能瓶颈，且不能容两个以上磁盘出错。从模块化系统的组织方法出发，提出一种采用标准模块化存储单元组成的通过胖树结构互连的大规模磁盘阵列结构MT2RAID，分别就其各种数据分布的性能和可靠性进行了分析和讨论。原型系统测试结果表明，相比集中式磁盘阵列结构，MT2RAID也具有较高的性能。

| Abstract: | Traditional disk arrays have centralized control architecture. The number of connected disks is constrained by the system bus. Centralized RAID architecture easily generates performance bottleneck and can not tolerate more than two disks faults. This paper proposed MT2RAID,a modular tree-connected multi tier RAID architecture for large scale disk arrays. MT2RAID is built from a collection of commodity components. Storage units are connected through fat tree based interconnection channels. The performance and reliability of different MT2RAID level were also analyzed and discussed. Prototype experimental results show that MT2RAID also has performance advantages compared with centralized RAID architecture. |
