Zoning
Zoning allows the user to divide the fabric ports into zones for more efficient and
secure communication among functionally grouped nodes. There are several types
of zones and a port may be defined in any or all of them. No port can be in all zone
types simultaneously.
• Hard Zones
(MKII-8 and MKII-16) Hard Zones follow physical boundaries within a
Single-Stage Switch chassis and limit the communication of a port to only
other ports in the same Hard Zone. There may be as many as four Hard Zones
and a particular port may be in only one of them. Hard Zones are not avail-
able in multi-stage fabrics.
(SANbox-8 and SANbox-16) Hard Zones on the SANbox-8 and SANbox-16
allow the division of the fabric (one or more Switch chassis) into as many as
16 fabric-wide zones that define the ports that may communicate with each
other. A particular port may be placed in only one Hard Zone (no overlapping
Hard Zones). If Hard Zones are enabled, Broadcast Zones and Name Server
zones may not cross the defined Hard Zone boundaries.
• Broadcast Zones
(All Models) Broadcast Zones allow the division of the fabric (one or more
Switch chassis) into as many as 16 fabric-wide zones that define the area of
Broadcasts. A particular port may be placed in one or more of these Broad-
cast Zones. A port will broadcast to all ports in the same Broadcast Zone (or
zones) in-which the port is defined. If Hard Zones are enabled, Broadcast
Zones may not cross the defined Hard Zone boundaries.
• Name Server Zones
(All Models) Name Server Zones allow the division of the fabric (one or
more Switch chassis) into as many as 256 fabric-wide zones that define
which ports or devices receive Name Server information. A particular port or
device WWN may be defined in one or more of these Name Server Zones. If
Hard Zones are enabled, Name Server Zones may not cross the defined Hard
Zone boundaries.
Name Server Zones are definable in one of two types, Port or WWN. The
chosen type is selected from the Topology window and applies to the entire
fabric.
If a zone is defined by port number, a port will receive Name Server informa-
tion for all ports in the same Name Server Zone (or zones) in-which the port
is defined.
