Zoning overview

Basic Zones
Basic zoning enables you to partition a storage area network (SAN) into logical groups of devices
that can access each other. For example, you can partition a SAN into two zones, winzone and
unixzone, so that the Windows servers and storage do not interact with UNIX servers and storage.
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 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.
• 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.
