摘要
针对由于数据量的迅猛增长 ,在存储系统性能和整个系统性能之间出现的严重失衡问题 ,研究提出了分布式数据镜像系统的架构和运行机制。分布式并行数据传输技术充分利用多个互联服务器的总带宽 ,实现高数据吞吐量 。
Rapid data growth has created a serious imbalance between storage system performance and system functionality. Based on it, this paper describes the distributed data mirror architecture and mechanisms, which employs the aggregate bandwidth of multiple data servers connected by Internet to achieve high data throughput. One promising approach is the use of distributed parallel data transfer techniques.
