Fabric OS Native and Access Gateway modes
The SAN24B-5 can function in either Fabric OS Native mode or Access Gateway
mode. The switch is shipped in Fabric OS Native mode by default.
v You can enable Access Gateway mode using Fabric OS commands or Web Tools.
Attention:
You must install the license for any additional port activations
before enabling the Access Gateway mode.
v When you enable Access Gateway, you can use the default F_Port-to-N_Port
mappings or change this mapping using command line interface (CLI) or Web
Tools, after you configure an IP address using instructions in “Setting the switch
IP address” on page 15.
v
Access Gateway simplifies SAN deployment by using N_Port ID Virtualization
(NPIV). NPIV provides Fibre Channel switch functions that improve switch
scalability, manageability, and interoperability. For more information on Access
Gateway, refer to the following:
– For a list of F_Ports mapped to N_Ports by default, refer to “Access Gateway
default port mapping” on page 43.
– For general information and details on using Access Gateway, refer to the
Access Gateway Administrator’s Guide .
– For specific instructions to prepare the edge fabric before connecting it to
Access Gateway (since Access Gateway relies on NPIV technology for its
connection to the edge fabric), refer to the
Access Gateway Administrator’s Guide
Note: Access Gateway cannot be connected directly into an array. It requires a
fabric to support NPIV.
v Fabric OS features available to the switch depend on whether the switch is
configured in Access Gateway or Fabric OS Native mode. For a list of available
features for each mode, refer to the
Access Gateway Administrator’s Guide .
v In Access Gateway mode, cascading is not available for the SAN24B-5. Refer to
the latest
Access Gateway Administrator’s Guide for details on any other
restrictions specific to the SAN24B-5.
v
In Fabric OS Native mode, the switch provides up to 24 external Fibre Channel
ports. These universal and self-configuring ports are capable of becoming one of
the following port types:
