Zoning overview
21
•
QoS zones
Assign high or low priority to designated traffic flows. Quality of Service (QoS) zones are
standard zones with additional QoS attributes that you select when you create the zone.
•
Traffic Isolation zones (TI zones)
Isolate inter-switch traffic to a specific, dedicated path through the fabric. Refer to “Traffic
Isolation zones” on page 916 for more information.
Online zoning
Online zoning allows you to do the following:
•
View both defined and active zone information in the fabric.
•
Create and modify zones and zone configurations in the software zone database.
•
Activate a zone configuration in order to publish the zone information in the selected fabric.
•
Deactivate the current active zone configuration.
•
Configure zoning policies in the selected fabric.
•
Generate zoning reports for the fabric.
NOTE
Online zoning is supported in Fabric OS and in Network OS.
Offline zoning
NOTE
Fabric OS Offline zoning is available only for Enterprise and Professional Plus editions.
Offline zoning enables you to copy a fabric zone database and edit it offline. The benefits to offline
zoning include the following:
•
You want to make changes to the zone database now, but apply them later.
For example:
-
If you make incremental changes to zoning on an ongoing basis, but want to apply the
changes to the fabric during scheduled downtime.
-
If you are expecting new servers to be delivered, but want to make changes to zoning now
and apply the changes after the servers are delivered and ready to go online.
•
You want to keep multiple copies of the zone database and switch between them.
For example, if you want to allow specific servers access to tape drives for backup during
specific time windows, you can have multiple zone databases (one or more for backup and one
for normal operation) and switch between them easily.
•
You want to analyze the impact of changes to storage access before applying the changes.
For example, if you deploy a new server and want to ensure that the zoning changes result in
only the new server gaining access to specific storage devices and nothing else. Refer to
“Comparing zone databases” on page 923.
