Preparing for cluster and SVM peering

You must create peer relationships between source and destination clusters and between source and destination SVMs before you can replicate Snapshot copies using SnapMirror. A peer relationship defines network connections that enable clusters and SVMs to exchange data securely.

  • Peering basics
    Clusters and SVMs in peer relationships communicate over the intercluster network using intercluster logical interfaces (LIFs). An intercluster LIF is a LIF that supports the "intercluster-core" network interface service and is typically created using the "default-intercluster" network interface service policy. You must create intercluster LIFs on every node in the clusters being peered.
  • Prerequisites for cluster peering
    Before you set up cluster peering, you should confirm that the connectivity, port, IP address, subnet, firewall, and cluster-naming requirements are met.
  • Using shared or dedicated ports
    You can use dedicated ports for intercluster communication, or share ports used by the data network. In deciding whether to share ports, you need to consider network bandwidth, the replication interval, and port availability.
  • Using custom IPspaces to isolate replication traffic
    You can use custom IPspaces to separate the interactions that a cluster has with its peers. Called designated intercluster connectivity, this configuration allows service providers to isolate replication traffic in multitenant environments.
