Abstract: One or more techniques and/or computing devices are provided for replicating virtual machine disk clones. For example, a first storage controller, hosting first storage, may have a synchronous replication relationship with a second storage controller hosting second storage. A virtual machine, within the first storage, may be specified as having synchronous replication protection. Accordingly, virtual machine disk clones of a virtual machine disk of the virtual machine may be replicated from the first storage to the second storage. For example, virtual machine disk clones may be synchronous replicated, replicated by a resync process invoked by a hypervisor agent, and/or stored and replicated from a clone backup directory.

Abstract: Recovery support techniques for storage virtualization environments are described. In one embodiment, for example, a method may be performed that comprises defining, by processing circuitry, a storage container comprising one or more logical storage volumes of a logical storage array of a storage system, associating the storage container with a virtual volume (vvol) datastore, identifying metadata for a vvol of the vvol datastore, and writing the metadata for the vvol to the storage system. Other embodiments are described and claimed.

Abstract: The techniques introduced here provide a storage server migration that is non-disruptive to client applications. The techniques described here allow the migration of data from a source storage server to a destination storage server without the need for planned downtime typically associated with storage server migration. Using the techniques described here, data migration operations are performed while client applications continue to run and access data from the source storage server. Once data migration operations are complete, all applications and clients are transitioned to the destination storage server without disruption to the client applications.

Abstract: One or more techniques and/or computing devices are provided for moving a consistency group having a replication relation. For example, a first consistency group of storage objects (e.g., files, logical unit numbers (LUNs), etc.) within first storage may have a replication relationship with a second consistency group within second storage (e.g., the second consistency group is maintained as a synchronously replicated copy of the first consistency group). A volume copy operation, a single file move on demand command, a single file restore command, or other functionality is used to move the first consistency group from the first storage to third storage, such as for load balancing, to create a moved first consistency group within the third storage. A new replication relationship is established between the moved first consistency group and the second consistency group, and the moved first consistency group and the second consistency group are resynchronized.
