Secure SAN Zoning Best Practices

This paper describes and clarifies Zoning, a security feature in Storage Area Network (SAN) fabrics. By understanding the terminology and implementing Zoning best practices, a Brocade SAN fabric can be easily secured and scaled while maintaining maximum uptime. Zoning not only prevents a host from unauthorized access of storage assets, but it also stops undesired host-to-host communication and fabric-wide Registered State Change Notification (RSCN) disruptions. RSCNs are managed by the fabric Name Server and notify end devices of events in the fabric, such as a storage node or a switch going offline.
