How fan-out deployments work

SnapMirror supports multiple-mirrors and mirror-vault fan-out deployments.

A multiple-mirrors fan-out deployment consists of a source volume that has a mirror relationship to multiple secondary volumes.

A mirror-vault fan-out deployment consists of a source volume that has a mirror relationship to a secondary volume and a SnapVault relationship to a different secondary volume.

Starting with ONTAP 9.5, you can have fan-out deployments with SnapMirror Synchronous relationships; however, only one relationship in the fan-out configuration can be a SnapMirror Synchronous relationship, all the other relationships from the source volume must be asynchronous SnapMirror relationships.
