Abstract: One or more techniques and/or systems are provided for dynamic mirroring. A first storage node and the second storage node within a first storage cluster may locally mirror data between one another based upon a local failover partnership. The first storage node and a third storage node within a second storage cluster may remotely mirror data between one another based upon a primary disaster recovery partnership. If the third storage node fails, then the first storage node may remotely mirror data to a fourth storage node within the second storage cluster based upon an auxiliary disaster recovery partnership. In this way, data loss protection for the first storage node may be improved, such that the fourth storage node provide clients with access to mirrored data from the first storage node in the event the second storage node and/or the third storage node are unavailable when the first storage node fails.

Abstract: Direct monitoring of a plurality of storage nodes in a primary cluster is performed based on connectivity with the storage nodes. Indirect monitoring of a first storage node is performed, in response to direct monitoring of the first storage node indicating failure of the connectivity with the first storage node, wherein a second storage node of the plurality of nodes is a backup node for the first storage node. The indirect monitor of the first storage node indicates failure of the first storage node in response to performance of storage access operations by the second storage node that were previously performed by the first storage node. A cluster-switch operation is initiated to switch to from the primary cluster to a backup cluster based on an occurrence of at least one cluster-failure condition that comprises the indirect monitor of the first storage node indicating failure of the first storage node.

Abstract translation: 基于与存储节点的连接性来执行主集群中的多个存储节点的直接监视。 响应于对第一存储节点的直接监视指示与第一存储节点的连接失败，执行第一存储节点的间接监视，其中多个节点中的第二存储节点是第一存储节点的备份节点 。 响应于先前由第一存储节点执行的第二存储节点的存储访问操作的性能，第一存储节点的间接监视器指示第一存储节点的故障。 基于至少一个集群故障状况的发生，启动集群交换操作以从主集群切换到备份集群，所述集群故障条件包括指示第一存储节点的故障的第一存储节点的间接监视。

Abstract translation: 提供一种或多种技术和/或系统用于动态镜像。 基于本地故障切换伙伴关系，第一存储集群内的第一存储节点和第二存储节点可以在彼此之间本地镜像数据。 基于主灾难恢复伙伴关系，第二存储集群内的第一存储节点和第三存储节点可以彼此远程镜像数据。 如果第三存储节点发生故障，则第一存储节点可以基于辅助灾难恢复伙伴关系将数据远程镜像到第二存储集群内的第四存储节点。 以这种方式，可以改善第一存储节点的数据丢失保护，使得第四存储节点在第二存储节点和/或第三存储节点不可用的情况下向客户端提供对来自第一存储节点的镜像数据的访问 当第一个存储节点发生故障时。
