Brocade Access Gateway and NPIV
Access Gateway (AG) allows you to configure the enterprise fabric to handle additional N_Ports
instead of domains by configuring F_Ports to connect to the fabric as N_Ports. This increases the
number of device ports that can be connected to a single fabric. Multiple AGs can connect to the
DCX enterprise-class platforms, directors, and switches.
The switches in AG mode are logically transparent to the host and the fabric. The number of hosts
that have access to the fabric can be increased without increasing the number of switches. This
simplifies the configuration and management in a large fabric by reducing the number of domain
IDs and ports.
NOTE
The SMI Agent does not support the discovery of an Access Gateway-enabled switch as a seed
switch, using Extrinsic method, except for the Encryption Switch.
Node Port Initialized Virtualization (NPIV) allows a single Fibre Channel port to appear as multiple
distinct ports. It provides a separate port identification and security zoning within the fabric for
each operating system image. Each operating system image has its own unique physical port.
For additional information about Access Gateway, refer to the Access Gateway Administrator’s
Guide.
For additional information about NPIV, refer to the Fabric OS Administrator’s Guide.
Registration
Figure 43 shows the SNIA Profile Registration Profile model to advertise the NPIV profile.
FIGURE 43 NPIV profile registration model
When an Access Gateway switch exists with devices attached in the discovered fabric, the
Brocade_RegisteredProfile (N_Port Virtualizer) is mapped to Brocade_AccessGateWay using
Brocade_ElementConformsToProfile association class.
