FlexVol

Use NetApp FlexVol technology to create virtual volumes; manage and move them independent of physical storage.

NetApp® FlexVol® storage-virtualization technology enables you to respond to changing storage needs fast, lower your overhead, avoid capital expenses, and reduce disruption and risk. FlexVol technology aggregates physical storage in virtual storage pools, so you can create and resize virtual volumes as your application needs change. 

With FlexVol you can improve—even double—the utilization of your existing storage and save the expense of acquiring more disk space. In addition to increasing storage efficiency, you can improve I/O performance and reduce bottlenecks by distributing volumes across all available disk drives.
