6.4 Zoning and Cascaded Switches
This section provides a brief overview of zoning and cascaded switches.
6.4.1 Zoning
A zone is a logical subset of the Fibre Channel devices connected to the
fabric. Zoning allows partitioning of resources for management and access
control. In some configurations, it may provide for more efficient use of
hardware resources by allowing one switch to serve multiple clusters or even
multiple operating systems.
Figure 6–8 provides an example configuration using zoning. This
configuration consists of two independent zones with each zone containing
an independent cluster.
