About the Embedded Switch Module
The Brocade 5450 Embedded Switch Module is a 26-port Fibre Channel module with 8 external
ports and 18 internal ports that installs in a Fujitsu BX900 Blade Server chassis. Although the
product may ship with a specific number of ports enabled, it can be upgraded to 26 ports through
Ports on Demand (POD) licensing. All ports support link speeds up to 8 Gbps.
Fabric OS Native and Access Gateway modes
The Embedded Switch Module can function in either Fabric OS Native mode or Brocade Access
Gateway mode. Features available on the Embedded Switch Module depend on whether the
module is configured in Access Gateway or Fabric OS Native mode.
• The Embedded Switch Module is shipped in Fabric OS Native mode by default.
• Access Gateway mode simplifies SAN deployment by using NPIV technology. NPIV provides
Fibre Channel switch functions that improve Embedded Switch Module scalability,
manageability, and interoperability. For more information on Access Gateway, refer to the
following:
- For a list of Embedded Switch Module F_Ports mapped to N_Ports in the Embedded
Switch Module as shipped from the factory, refer to “Access Gateway Mode default port
mapping” on page 41.
- For general information and details on using Access Gateway, refer to the Brocade Access
Gateway Administrator’s Guide.
- Because Access Gateway relies on NPIV technology for its connection to the edge fabric,
you may have to prepare the edge fabric before connecting it to Access Gateway. Please
refer to the SAN TECH NOTE – Preparing to Install the Brocade Access Gateway for specific
instructions.
NOTE
Access Gateway cannot be connected directly into a storage array.
