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. No port can be in all
zone types simultaneously.
and secure communication among functionally grouped nodes. There are
several types of zones and a port may be defined in any. No port can be in all
zone types simultaneously.
Hard Zones
Hard Zones allow the division of the Fabric (one or more Switch chassis) into
as many as 16 Fabric-wide zones that define the ports that can communicate
with each other. A particular port may be placed in only one Hard Zone (no
overlapping Hard Zones). If Hard Zones are enabled, Name Server Zones and
SL Zones will not communicate across defined Hard Zone boundaries.

SL Zones will not communicate across defined Hard Zone boundaries.
Broadcast Zone
Zone type used to filter broadcast traffic away from end nodes that cannot use
or interpret it. A port will broadcast to all ports in the same Broadcast Zone(s)
in which the port is defined. Broadcast zoning is primarily used for doing IP
over Fibre Channel or when mixing IP and SCSI traffic on the switch. These
zones are not yet useful or interesting in Suns current SAN implementations.

SL_Port Zone
A set of ports and their connected devices (zone) that behave as a single
private loop. SL Zones on the switch allow the division of the Fabric (one
or more Switch chassis) into Fabric-wide zones that define the ports that
can communicate with each other.

Cascade
Connection of two or more switches together to increase the number of
available ports or to allow for increased distances between components of the
SAN.

SAN.
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. If Hard Zones are enabled, Name Server Zones will
not communicate across defined Hard Zone boundaries.

Fabric
Fibre channel network built around one or more switches. It is also common to
refer to something as a "Fabric device" or being in "Fabric mode". When used
in this context, it simply means a public device, capable of logging into a
Fabric and having public loop characteristics (as opposed to a private loop
legacy device).
