Management Server - Collects and reports management information,
such as link usage, error statistics, link quality, and similar
Quality of Service Facilitator - Performs fabric-wide bandwidth
and latency management.
3.4. Fibre Channel Nodes
A fibre channel node has one or more fabric-attached N_PORTs. The
node and its N_PORTs have the following associated identifiers:
a) A worldwide-unique identifier for the node.
b) A worldwide-unique identifier for each N_PORT associated with the
c) For each N_PORT attached to a fabric, a 24-bit fabric-unique
address with the properties defined in Section 3.7.1. The fabric
address is the address to which frames are sent.
Each worldwide-unique identifier is a 64-bit binary quantity with the
format defined in [FC-FS].
3.5. Fibre Channel Device Discovery
In a switched or mixed fabric, fibre channel devices and changes in
the device configuration may be discovered by means of services
provided by the fibre channel Name Server and Fabric Controller.
The Name Server provides registration and query services that allow a
fibre channel device to register its presence on the fabric and to
discover the existence of other devices. For example, one type of
query obtains the fabric address of an N_PORT from its 64-bit
worldwide-unique name. The full set of supported fibre channel name
server queries is specified in [FC-GS3].
The Fabric Controller complements the static discovery capabilities
provided by the Name Server through a service that dynamically alerts
a fibre channel device whenever an N_PORT is added or removed from
the configuration. A fibre channel device receives these
notifications by subscribing to the service as specified in [FC-FS].
