ONTAP drivers

Contributors juliantap

Astra Trident provides five unique ONTAP storage drivers for communicating with ONTAP clusters.

Astra Control supported drivers

Astra Control provides seamless protection, disaster recovery, and mobility (moving volumes between Kubernetes clusters) for volumes created with the ontap-nas, ontap-nas-flexgroup, and ontap-san drivers. See Astra Control replication prerequisites for details.

Warning

  • You must use ontap-nas for production workloads that require data protection, disaster recovery, and mobility.

  • Use ontap-san-economy when anticipated volume usage is expected to be much higher than what ONTAP supports.

  • Use ontap-nas-economy only where anticipated volume usage is expected to be much higher than what ONTAP supports, and the ontap-san-economy driver cannot be used.

  • Do not use use ontap-nas-economy if you anticipate the need for data protection, disaster recovery, or mobility.

Note ONTAP backends can be authenticated by using login credentials for a security role (username/password) or the private key and the certificate that is installed on the ONTAP cluster. You can update existing backends to move from one authentication mode to the other with tridentctl update backend.
