Updated FlexGroup Technical Reports now available for ONTAP 9.6!

ONTAP 9.6 is now available, so that means the TRs need to get a refresh.


There are some new features in ONTAP 9.6 for FlexGroup volumes, including:

  • Elastic Sizing
  • MetroCluster support
  • SMB CA shares
  • FlexGroup rename/shrink

The TRs cover those features, and there are some updates to other areas that might not have been as clear as they could have been. I also added some new use cases.

Also, check out the newest FlexGroup episode of the Tech ONTAP Podcast:
