3-Site Replication

DHAKSHINAMOORTHY_B — Fri, 24 Jul 2020 07:36:13 GMT

Hi Team,

Do we have support for 3-site replication in latest CDOT 9.7P5?

One of the customer has Primary Site, Near DR and FAR DR. Would like to check if NetApp supports 3-site replication?

The one caveat is that there is currently no support for FlexGroup volumes with 3-site DR.

Beginning 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 SnapMirror asynchronous relationships.

Beginning with ONTAP 9.6, SnapMirror synchronous relationships are supported in a mirror-mirror cascade deployment. Only the primary and secondary volumes can be in a SnapMirror synchronous relationship. The relationship between the secondary volumes and tertiary volumes must be asynchronous.
