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. A zone can be a member of 
more than one zone set. Several zone sets can be defined for a fabric, but only 
one zone set can be active at one time. The active zone set determines the 
current fabric zoning.
A zoning database is maintained on each switch module consisting of all 
inactive zone sets, the active zone set, all zones, aliases, and their 
membership. 
 describes the zoning database limits, excluding the 
active zone set. Refer to the EFCM Basic Management Guide for more 
information about zoning.
Soft Zones
Soft zoning divides the fabric for purposes of controlling device discovery. 
Devices in the same soft zone automatically discover and communicate freely 
with all other members of the same zone. The soft zone boundary is not 
Table 2-1.
Zoning Database Limits
Limit
Description
MaxZoneSets
Maximum number of zone sets (256).
MaxZones
Maximum number of zones (2000).
MaxAliases
Maximum number of aliases (2500).
MaxTotalMembers
Maximum number of zone and alias members (10000) that can be 
stored in the switch module’s zoning database.
MaxZonesInZoneSets
Maximum number of zones that are components of zone sets 
(2000), excluding the orphan zone set, that can be stored in the 
switch module’s zoning database. Each instance of a zone in a 
zone set counts toward this maximum.
MaxMembersPerZone
Maximum number of members in a zone (2000)
MaxMembersPerAlias
Maximum number of members in an alias (2000)
