    Abstract: One or more techniques and/or devices are provided for storage virtual machine relocation (e.g., ownership change) between storage clusters. For example, operational statistics of a first storage cluster and a second storage cluster may be evaluated to identify a set of load balancing metrics. Ownership of one or more storage aggregates and/or one or more storage virtual machines may be changed (e.g., permanently changed for load balancing purposes or temporarily changed for disaster recovery purposes) between the first storage cluster and the second storage cluster utilizing zero-copy ownership change operations based upon the set of load balancing metrics. For example, if the first storage cluster is experiencing a relatively heavier load of client I/O operations and the second storage cluster has available resources, ownership of a storage aggregate and a storage virtual machine may be switched from the first storage cluster to the second storage cluster for load balancing.

    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: Techniques are provided for synchronous replication based cutover. An asynchronous replication process is executed to perform asynchronous incremental transfers of data of a storage object from a first computing environment to a replicated storage object at a second computing environment until a cutover criteria is met. A synchronous replication process is executed to synchronously replicate operations, targeting the storage object, to the replicated storage object based upon the cutover criteria being met. A cutover is performed to direct operations from targeting the storage object to targeting the replicated storage object based upon the synchronous replication process reaching a steady state of synchronous replication for sub-objects of the storage object, where operations are committed to both the storage object and the replicated storage object.

    Abstract: A volume rehost tool migrates a storage volume from a source virtual server within a distributed storage system to a destination storage server within the distributed storage system. The volume rehost tool can prevent client access to data on the volume through the source virtual server until the volume has been migrated to the destination virtual server. The tool identifies a set of storage objects associated with the volume, removes configuration information for the set of storage objects, and removes a volume record associated with the source virtual server for the volume. The tool can then create a new volume record associated with the destination virtual server, apply the configuration information for the set of storage objects to the destination virtual server, and allow client access to the data on the volume through the destination virtual server.
