What cluster peer intercluster connectivity is

You should know about the interfaces and ports that you put together to create a cluster peer intercluster connection and how they are used. Knowing this information might reduce the amount of time you use to create the cluster peer intercluster connectivity.

Cluster peer intercluster connectivity consists of intercluster logical interfaces (LIFs) that are assigned to network ports. The intercluster connection on which replication occurs between two different clusters is defined when the intercluster LIFs are created. Replication between two clusters can occur on the intercluster connection only; this is true regardless of whether the intercluster connectivity is on the same subnet as a data network in the same cluster.

The IP addresses assigned to intercluster LIFs can reside in the same subnet as data LIFs or in a different subnet. When an intercluster LIF is created, it uses routes that belong to the System SVM that the intercluster LIF is in.

System Manager enables you to create an authenticated cluster peer relationship between clusters that are running Data ONTAP 8.3 or later. An authenticated peer relationship uses passphrases to provide secure intercluster communication.
