Configuring FC zones
Overview
The VSAN technology divides a physical SAN into multiple VSANs, which are separated from one
another, and provides more secure, reliable, and flexible services. A VSAN, however, cannot perform
access control over the servers and disk devices (or the N_Ports) connected to a fabric. N_Ports in the
same VSAN can access one another only if these N_Ports register name services. This creates data
security risks.
Zoning can solve the preceding problem by dividing a VSAN into zones and adding N_Ports to different
zones for different purposes. In this way, N_Ports in different zones are separated to implement access
control.
Zone database
To control access among N_Ports, you can divide N_Ports into different zones as needed, which
comprise a zone set. The same N_Ports can form multiple zone sets according to different zone division
policies. These zones and zone sets comprise a zone database.
Zone database structure
The zone database is organized into three levels: zone set, zone, and zone member.
Figure 28 Zone database structure
In the zone database structure:
• A zone set is a set of zones. A zone is a set of zone members, which are N_Ports. Zone membership
can be identified by the port WWN (pWWN) or FC address of an N_Port.
