Migration: Import External Storage
Migration: Import External Storage
-
PowerStore supports importing external storage from supported storage platforms. The PowerStore import feature supports the following block storage resources from other arrays: LUNs and volumes, consistency groups and volume groups, and thick and thin clones, depending on the source system. PowerStore can manage the import process non-disruptively with a host orchestrator called a host plug-in which is installed on all hosts that access the source data. Agentless import is also supported, but it is a disruptive process which requires application downtime. Go to Migration > Import External Storage (see Figure 37) to connect to supported storage platforms and enable a nondisruptive import. To connect to a remote system from PowerStore, you must have the management IP address, iSCSI IP addresses, and credentials. FC target WWNs are automatically discovered.
PowerStoreOS versions 3.0 and later support native file import. Dell VNX2 is supported with 3.0 and later, and Unity is supported with 4.0 and later. This capability includes support for both NFS and SMB file systems. Proper networking and configuration of the File Import Interface is required to use this import functionality.
PowerStoreOS versions 4.0 and later support import from universal remote systems, which allows the PowerStore to perform agentless imports for a wide range of block storage systems. FC and iSCSI backend connections are supported and the discovery does not require control path connectivity to the remote storage system.
For more information about imports and the import process, see the white paper Dell PowerStore: Migration Technologies.
Note: Ensure that all existing hosts and storage systems are referenced in the PowerStore Simple Support Matrix. If a system is not referenced, open an RPQ for support.
