| Volume mobility | Live Migrate (included in base product) enables host-transparent data movement among arrays; see also Federation section | |
| Federated multi-array systems | Live Migrate (included in base product) enables host-transparent movement of volumes among arrays Snapshots maintained/preserved during migration | |
| Thin Import | Space-efficient, non-disruptive data migration from PS Series (EqualLogic) and MD3 arrays | |
| Thin Clones | Clone standalone volumes with zero duplication of data Clones maintain independent snapshots and replication Ideal for VDI, test/dev, other applications that require discrete instances of common data More efficient than dedupe for database copies | |
