Built-in (native)
PowerFlex has native snapshot capabilities. These snapshot capabilities include the support of Consistency Groups. This assures that snapshots of different volumes within the same group that are taken together at exactly the same time.

VxFlex OS 3.0 introduced FIne Granularity (FG) storage pools. Fine Granularity (FG) snapshots are Redirect on Write (RoW) instead of Copy on Write (CoW) that is used in Medium Granularity (MG) storage pools.

PowerFlex 3.5 introduces Secure Snapshots. These storage snapshots cannot be deleted and thus enable compliance with the financial and healthcare industry.
