Device Access
Device Access
Consider device access needs within the fabric. Access is controlled by the use
of zones and zone sets. Some zoning strategies include the following:
• Group devices by operating system.
• Separate devices that have no need to communicate with other devices in
the fabric or have classified data.
• Separate devices into department, administrative, or other functional
group.
• Reserve a path and its bandwidth from one port to another.
A zone is a named group of devices that can communicate with each other.
Membership in a zone can be defined by switch module domain ID and port
number, port Fibre Channel address, or by device worldwide name (WWN).
Devices can communicate only with devices within the same zone. The
switch module supports both hard and soft zones. The switch supports one
zone set; that is, the active zone set. The active zone set determines the current
fabric zoning.
A zoning database is maintained on each switch module consisting of the
active zone set, all zones, and their membership. Table 2-1 describes the
zoning database limits, excluding the active zone set. Refer to the McDATA
Switch Module Management Guide for more information about zoning.

the switch module’s zoning database.
MaxZonesInZoneSets Maximum number of zones that are components of the active zone
set (2047), excluding the orphan zone set, that can be stored in
the switch module’s zoning database.
