Applies to

  • ONTAP 9

  • NVMe self-encrypting drives

Answer

  • No, the encryption mode will be “data” for NVMe SEDs by default. The mode cannot be changed to full as FIPS authentication keys cannot be assigned.

Additional Information

  • Encryption mode shows “data”, that means data is protected; drive is not in FIPS-compliance mode.

  • NVMe self-encrypting drives do not have FIPS 140-2 or FIPS 140-3 certification.

  • However, these disks use AES 256-bit transparent disk encryption to protect data at rest.

  • Beginning with ONTAP 9.6, self-encrypting NVMe drives that have not undergone FIPS testing are supported on AFF A800, A320, and later systems. These drives, called SEDs, offer the same encryption capabilities as FIPS drives.

  • What is the difference between FIPS and SED drives?
