摘要: 针对传统复制技术存在的问题,在研究复杂存储网络高可用系统结构的基础上,分别设计了面向恢复的自适应复制协议和算法,它们允许系统中同时有多个复制组,且每个复制组成员可动态变化。实验结果表明,新协议和算法能适用于各种复杂的存储网络环境。

关键词: 存储网络, 高可用, 复制协议, 容错

Abstract: Aiming at the problems existed in traditional replication technology, and on basis of analyzing the High Availability(HA) system structure for complex storage network, a Recovery-Oriented self-Adaptable Replication Protocol(ROARP) and a Recovery-Oriented Request Recording and Checkpoint(RORRC) are designed, which allows multiple replication groups exist in one system, and each member of the group is active. Experimental results show these novel protocol and algorithm are fit for varied complex storage networks.

Key words: storage network, High Availability(HA), replication protocol, fault tolerance
