Explanation
Zoning is an FC switch function that enables node ports within the fabric to be logically segmented into groups and communicate with each other within the group. Whenever a change takes place in the name server database, the fabric controller sends a Registered State Change Notification (RSCN) to all the nodes impacted by the change. If zoning is not configured, the fabric controller sends an RSCN to all the nodes in the fabric. Involving the nodes that are not impacted by the change results in increased fabric-management traffic. For a large fabric, the amount of FC traffic generated due to this process can be significant and might impact the host-to-storage data traffic. Zoning helps to limit the number of RSCNs in a fabric. In the presence of zoning, a fabric sends the RSCN to only those nodes in a zone where the change
