To set up a FlexCache volume on a Cloud Volumes ONTAP (CVO) HA pair where the origin cluster is an AFF HA pair at a company data center, each site typically needs at least two intercluster Logical Interface (LIFs). Here’s why:

Purpose of Intercluster LIFs:Intercluster LIFs are used for communication between different clusters, especially for operations involving data replication and FlexCache. Each cluster needs to have its intercluster LIFs configured to ensure proper communication across clusters.

Configuration Requirement:For a basic setup involving one origin and one destination cluster, at least one intercluster LIF per node is recommended to provide redundancy and ensure continuous availability, even if one node or one network path fails.

Best Practices:While two intercluster LIFs (one per node in an HA pair) are typically sufficient, larger deployments or environments requiring higher redundancy might opt for more intercluster LIFs.

For detailed guidance on setting up intercluster LIFs and configuring FlexCache volumes, consult the NetApp documentation on FlexCache and cluster peering: NetApp FlexCache Documentation.
