Zoning overview
Zones can be configured dynamically. They can vary in size, depending on the number of
fabric-connected devices, and devices can belong to more than one zone. Because zone members
can access only other members of the same zone, a device not included in a zone is not available
to members of that zone.

Traffic Isolation zones

A traffic isolation zone (TI zone) is a special zone that creates a dedicated path for a specific traffic
flow. TI zones are primarily for shaping and controlling traffic rather than partitioning access to
storage.

LSAN zone requirements

An LSAN zone enables device connectivity between fabrics connected in Fibre Channel Routing
(FCR) configurations without forcing you to merge fabrics. Extension switches like the 7500 provide
multiple mechanisms to manage interfabric device connectivity. Zones that contain hosts and
targets that are shared between the two fabrics need to be explicitly coordinated. To share devices
between any two fabrics, you must create an LSAN zone in both fabrics considering the following:

QoS zone requirements

A QoS zone is a special zone that assigns a Quality of Service (QoS) level for traffic flow between a
given host or target pair. The members of a QoS zone are WWNs of the host or target pairs. QoS
zones can contain only WWN members. A QoS zone has a special prefix, to differentiate it from a
regular zone. The formats and meaning of the QoS zone name prefix are shown in
names are not case dependent).

DRAFT: BROCADE CONFIDENTIAL
The name of an LSAN begins with the prefix LSAN_. The prefix is not case sensitive.
Members must be identified by their port WWN because port IDs are not necessarily unique
across fabrics.
