Abstract: Fault domains are defined which reflect, either physically or virtually, the topology of a networked computing environment. These defined fault domains are then used to control where cached data is replicated when running in a write back cache mode. Unlike known replication approaches, the present approach replicates such data according to a user's defined data policy and based on the defined fault domains thereby avoiding the user having to keep track of changes in computing system configurations or update their data policy when virtual machines migrate from one host computing system to another.

Abstract translation: 定义了故障域，物理上或虚拟地反映了网络计算环境的拓扑。 然后，这些定义的故障域用于在回写高速缓存模式下运行时控制缓存数据的复制位置。 与已知的复制方法不同，本方法根据用户定义的数据策略并基于定义的故障域来复制这样的数据，从而避免用户在虚拟机从一个虚拟机迁移时跟踪计算系统配置的变化或更新其数据策略 主机计算系统到另一个。
