NetApp - FlexVol vs Infinite Volume vs FlexGroup

FlexVol - ONTAP 7 - 16TB(32-bit Aggregate) and 100 TB(64-bit Aggregate) model dependent, Files 2 billion

Infinite Volume - ONAP 8.1.X - 20 PB, files 2 billions , spread across maximum of 10 nodes, single namespace metadata volume

FlexGroup - ONTAP 9.1 - 20 PB (200 constituent of 100TB), files 400 billion, spread across multiple nodes

FlexVol - Capability of increasing and decreasing volume capacity on the fly.  Can have multiple volume in single Aggregate.

Infinite volume is single namespace metadata volume therefore you get bigger volume of 20 PB but file limitation of 2 billions.

FlexGroup  volume contains multiple constituent that manage their own metadata and therefore has no single namespace metadata volume and it can have 2 * 200 billions files and bigger volume of 20PB.
