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:
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.
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.
