McDATA 4416 manual Device Access, Limit Description

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 2-1describes the zoning database limits, excluding the active zone set. Refer to the McDATA Switch Module Management Guide for more information about zoning.

Table 2-1. Zoning Database Limits

MaxTotalMembers	Maximum number of zone members (10,000) that can be stored in
	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.
