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.
