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 systems.

„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 domain ID and port number, port Fibre Channel address, or by device worldwide name (WWN). Devices can communicate only with devices that are within the same zone. 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 consisting of all inactive zone sets, the active zone set, all zones, aliases, and their membership. Table 3-1describes the zoning database limits, excluding the active zone set. Refer to the SANbox2-8c/16 Switch Management User’s Guide for more information about zoning.

Table 3-1. Zoning Database Limits

 

 

Limit

Description

 

 

MaxZoneSets

Maximum number of zone sets (256).

MaxZones

Maximum number of zones (1000).

MaxAliases

Maximum number of aliases (2500).

MaxTotalMembers

Maximum number of zone and alias members (10000)

 

that can be stored in the switch’s zoning database.

MaxZonesInZoneSets

Maximum number of zones that are components of

 

zone sets (1000), excluding the orphan zone set, that

 

can be stored in the switch’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)
