2.2.1.1 Zones Considerations

• McData 4500 switches only support one zoneset to configure and activate any point.

• All zones in a fabric configured based on the world-wide names (WWN) of the nodes and storage system.

• Default zones in fabric are disabled and all ports not in use are disabled in order to avoid.

• There are separate zones for each cluster, backup and management network.

• All ports connecting to tape drives will have RSCN (Registered Change Notification) disabled in order to avoid the interruptions to backups.

• All configuration are backed up periodically and all changes to SAN configurations will need careful evaluation and review.
