Zoning Database
Each switch has its own zoning database. The zoning database is made up of all
aliases, zones, and zone sets that have been created on the switch or received
from other switches. The switch maintains two copies of the inactive zoning
database: one copy is maintained in temporary memory for editing purposes; the
second copy is maintained in permanent memory. Zoning database edits are
made on an individual switch basis and are not propagated to other switches in
the fabric when saved.
There are two configuration parameters that affect the zoning database: Interop
Auto Save and Default Visibility. The Interop Auto Save parameter determines
whether changes to the active zone set that a switch receives from another switch
in the fabric will be saved to permanent memory on that switch. The Default
Visibility parameter permits or prohibits communication among ports/devices
when there is no active zone set. Refer to “Configuring the Zoning Database” on
page 3-28 for information about zoning configuration.
The following zoning limits are enforced during the configuration of zoning and
during a zoning database merge from the fabric:
MaxZoneSets is 256. The maximum number of zone sets that can be
configured on the switch.
MaxZones is 2000. The maximum number of zones that can be configured
on the switch.
MaxAliases is 2500. The maximum number of aliases that can be
configured on the switch.
MaxTotalMembers is 10,000. The maximum number of total zone and alias
members that can be configured on the switch. Aliases are considered zone
members since they can be added to a zone just like a normal zone
member.
MaxZonesInZoneSets is 2000. The maximum number of zone linkages to
zonesets that can be configured on the switch. Every time a zone is added
to a zoneset this constitutes a linkage.
MaxMembersPerZone is 2000. The maximum number of zone members
that can be added to any zone on the switch. Aliases are considered zone
members when added to a zone.
MaxMembersPerAlias is 2000. The maximum number of zone members
that can be added to any alias on the switch.
