■ Automatic, transparent distribution throughout the Fabric, a single
failure cannot interrupt Zoning Enforcement to other SAN connections
■ Automatic service scaling with Fabric size, no requirement to upgrade
systems as Switches are added and connectivity increases
■ Automatic, transparent deployment, no requirement for human
intervention unless Zoning Specification must change.
Questions and Answers about Zoning
1. What is Zoning?
Zoning is a Fabric service that provides an IT administrator more control over
the SAN, more management, and security for customizing environments.
Using Zoning, Fabric connected devices are arranged into logical groups over
the physical Fabric configuration. Zoning automatically and transparently
enforces access of information to the zone devices.
2. Why would I implement zones?
Zones can be configured to:
■ Unify heterogeneous environments
■ Create functional Fabric areas
■ Design closed user groups
■ Simplify resource utilization
■ Facilitate time sensitive functions
■ Secure Fabric areas.
3. Does Zoning minimize the Switch performance?
No. Zoning is based on the Simple Name Server (SNS), a Fabric service, for
this product version. And, Zoning does not impact SNS. Switch performance
is hardware-based.
4. Why is Zoning considered a Fabric service?
Services in the Fabric have these characteristics:
■ Administration from any Fabric Switch
■ Automatic, transparent distribution throughout the Fabric
■ Automatic service scaling with Fabric size
■ Automatic, transparent deployment.
