We are planning to upgrade from ONTAP version 8.3.2P12 to version 9.1P20 . When trying to download the image, we were presented with two options:
1- With NetApp Volume Encryption for FAS
2- Without NetApp Volume Encryption for FAS
Apparently, no matter which option we choose, the NVE will provide the ability to use the integrated OKM w/NVE to encrypt volumes.
What are the advantages of encrypting volumes? It is really necessary?
