摘要
在SAN环境下实现了一个开放系统与大型机数据共享系统,克服了传统客户/服务器数据共享模型的缺点,能有效地提高系统的数据传送性能;提出了一种基于共享磁盘映射关系的第三方数据传送方法,由于共享磁盘映射关系是动态建立的,因而系统具有良好的可扩展性;最后讨论了冗余存储路径容错和访问负载均衡功能的实现策略。
A heterogeneous data sharing system for Storage Area Network (SAN) is presented. A method for dynamically (creating) the mapping relationship among metadata server is suggested, which shared disks and their storage paths. Third-party data transfer in our system is based on the mapping relationship. More advanced functions such as multiple paths failover (and load) balance are also implemented by extending the mapping relationship. Because the mapping relationship is created (dynamically,) the whole system can scale well.
