Applies to

  • ONTAP 9
  • NetApp Volume Encryption (NVE)
  • NetApp Aggregate Encryption (NAE)

Answer

NetApp Volume Encryption (NVE)
  • Per Volume, Software-based, data-at-rest encryption solution
  • Available starting with NetApp ONTAP 9.1
  • Allows ONTAP to encrypt data and to have that data stored on disk without requiring self-encrypting drives.
  • Allows customers to use storage efficiency features that would be lost if the customer decided to encrypt at the application layer.
  • Customers can use any existing disk with NVE, which also includes NetApp Storage Encryption (NSE) drives for double or layered encryption.
NetApp Aggregate Encryption (NAE)
  • An enhancement of the software-based NVE data-at-rest solution.
  • Available starting with ONTAP 9.6.
  • NAE enables use of aggregate deduplication for greater storage efficiency.
  • Allows ONTAP to encrypt data for each volume with the keys shared for the aggregate.

 

Note: NVE and NAE are the only options available for encrypting data in NetApp MetroCluster software and ONTAP Select.
