text: Verify carefully that the devices that you plan to use to implement the intercluster link are 
  supported. 
  
  **Cluster configuration**
  If you configure replication services, you might decide to dedicate ports for intercluster 
  communication, intracluster traffic, or both. In that case, make sure that your cabling and 
  zoning reflects that decision. Also, such dedicated ports are inaccessible for host or back-end 
  storage traffic, so plan your volume mappings and hosts and back-end storage connections 
  accordingly.
