FlexArray virtualizes external storage, letting ONTAP own and present LUNs that reside on external SAN arrays as if they were native ONTAP storage. By connecting the external array to the ONTAP system, those external LUNs become visible and manageable through ONTAP, so hosts see them as regular ONTAP-backed LUNs with the same export policies and data-management capabilities. The other features handle data protection and recovery rather than changing how external storage is exposed; SnapVault targets backups to another array, SnapMirror handles replication between ONTAP systems, and SnapRestore restores data from snapshots.
