Applies to

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

Answer

  • NetApp offers three encryption options for disk encryption:
    • NetApp Volume Encryption (NVE)
    • NetApp Storage Encryption (NSE)
    • NetApp Aggregate Encryption (NAE)
  • These options are used to enhance the security of data and provide encryption at different levels.
    • NetApp Volume Encryption (NVE)
      • Provides encryption at the volume level.
      • It is a software-based encryption solution that allows for encrypting specific volumes.
      • NVE can be applied to existing volumes and operational environments, but may require volume recreation or data migration.
      • The performance impact during encryption is typically minor but varies based on the amount of data and system load.
    • NetApp Storage Encryption (NSE)
      • Offers disk-level encryption.
      • NSE utilizes Self-Encrypting Drives (SEDs).
      • Applying NSE to an existing non-encrypted system may necessitate data migration or system reconstruction.
      • Introducing encrypted drives requires hardware replacement, which may lead to service downtime.
    • NetApp Aggregate Encryption (NAE)
      • Provides encryption at the aggregate level.
      • NAE is an extension of NVE, encrypting all volumes within an aggregate.
      • To apply NAE, you need to create a new aggregate and migrate data.
