摘要： A data replication system having a redundant configuration including dual Fiber Channel fabric links interconnecting each of the components of two data storage sites, wherein each site comprises a host computer and associated data storage array, with redundant array controllers and adapters. The system employs the grouping of logical units into ‘association sets’, for logging and failover purposes. The concept of association sets allows the system provides for proper ordering of I/O operations during logging across multiple volumes. In addition, association sets are employed by system to provide failure consistency by causing the group of logical units/volumes to all fail at the same time, ensuring a point in time consistency on the remote site.

摘要翻译： 具有冗余配置的数据复制系统，其包括互连两个数据存储站点的每个组件的双光纤通道结构链路，其中每个站点包括具有冗余阵列控制器和适配器的主计算机和相关联的数据存储阵列。 系统将逻辑单元分组为“关联集”，用于记录和故障转移。 关联集的概念允许系统在跨多个卷记录期间提供I / O操作的正确排序。 此外，系统采用关联集合，通过使逻辑单元/卷的组同时失败来提供故障一致性，确保远程站点上的时间点一致性。
