Configuring Zones
56 Embedded Web Server User Guide
Zoning allows an administrator to:
■ Establish barriers between devices that use different operating systems. For
example, it is often critical to separate servers and storage devices with
different operating systems because accidental transfer of information from
one to another can delete or corrupt data. Zoning prevents this by grouping
devices that use the same operating systems into zones.
■ Create logical subsets of closed user groups. Administrators can authorize
access rights to specific zones for specific user groups, thereby protecting
confidential data from unauthorized access.
■ Create groups of devices that are separate from devices in the rest of a fabric.
Zoning allows certain processes (such as maintenance or testing) to be
performed on devices in one group without interrupting devices in other
groups.
■ Allow temporary access between devices for specific purposes.
Administrators can remove zoning restrictions temporarily (for example, to
perform nightly data backup), then restore zoning restrictions to perform
normal processes.
Figure 18 illustrates three zones established on a single managed product with
four devices in each zone. Devices in each zone can communicate with and access
devices only in their respective zones.
