Zoning uses logical device subsets within an SAN network for resource
partitioning for management and access control. Within a zone the device sets
may access one another. All Fabric connected devices can be configured into
one or more zones. Devices that are in different zones do not see each other.
Zoning allows you to setup:
■ Barriers between systems with different operating environments or uses.
■ Logical subsets of closed user groups within the Fabric.
■ Special areas separate from the rest of the Fabric. For example, for
testing or maintenance.
■ Temporary access among devices for specific purposes. For example,
enterprise backup.
Additionally, Zoning provides:
■ Greater flexibility – to manage a SAN with multiple operational
objectives
■ Finer configuration granularity to logically configure resources for
improved optimization and seclude environments for security
■ Versatility to meet application demands.
Zone Enforcement
A zone is enforced via software by:
■ Implementation based on Simple Name Server (SNS)
■ Is enforced across all Fabric Switches
SNS functionality is not degraded by supporting zones because:
■ There is no change to the SNS access protocol
■ If no zones are in force an SNS query responds with all ports
■ If one or more zones are in force an SNS query only responds with the
ports that are part of the requestor’s zone. If the requestor is not part of
the zone, an SNS query responds with no ports.
Setting Up Zones
Zoning supports:
■ Zone creation, deletion and display
