    Abstract: Synchronous local and cross-site switchover and switchback operations of a node in a disaster recovery (DR) group are described. In one embodiment, during switchover, a takeover node receives a failover request and responsively identifies a first partner node in a first cluster and a second partner node in a second cluster. The first partner node and the takeover node form a first high-availability (HA) group and the second partner node and a third partner node in the second cluster form a second HA group. The first and second HA groups form the DR group and share a storage fabric. The takeover node synchronously restores client access requests associated with a failed partner node at the takeover node.

    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 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。
