Abstract: Method and system for a non-disruptive migration of a source virtual storage system from a source cluster to a destination cluster is provided. The method includes monitoring a current transfer rate for migrating information from the source cluster to the destination cluster during a migration operation; iteratively reducing a rate at which I/O requests are processed until a transfer rate for transferring the information from the source cluster to the destination cluster within the duration is reached; and entering a cutover phase for the migration operation when the virtual storage system presented by the source cluster is taken offline for the duration and after the information is migrated to the destination cluster, the virtual storage system is presented by the destination cluster.

Abstract translation: 提供了源虚拟存储系统从源集群到目标集群的非中断迁移的方法和系统。 该方法包括监视在迁移操作期间将信息从源集群迁移到目的地集群的当前传输速率; 迭代地减少处理I / O请求的速率，直到达到在持续时间内将信息从源集群传送到目标集群的传输速率; 并且当由源集群呈现的虚拟存储系统在持续时间内脱机并且在将信息迁移到目的地集群之后，进入迁移操作的切换阶段，则由目的地集群呈现虚拟存储系统。

Abstract: A method includes receiving a change in a primary configuration of a primary storage node while the primary storage node is operational, wherein primary data stored in the primary storage node is to be backed up as backup data in a backup storage node. The method includes locating at least one identifier in the change that identifies the primary storage node. The method includes replacing the at least one identifier in the change that identifies the primary storage node with an identification of the backup storage node to create an updated configuration change. The method includes updating a backup configuration of the backup storage node based on the updated configuration change.

Abstract translation: 一种方法包括在主存储节点可操作时接收主存储节点的主配置的改变，其中存储在主存储节点中的主数据将作为备份存储节点中的备份数据进行备份。 该方法包括在识别主存储节点的改变中定位至少一个标识符。 该方法包括用识别主存储节点的变化中的至少一个标识符替换备份存储节点的标识以创建更新的配置更改。 该方法包括基于更新的配置更改来更新备份存储节点的备份配置。
