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 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
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
