This section discusses a method for connecting the MX9116n FSE to an FC storage array connected to existing FC switches using the NPIV Proxy Gateway (NPG) mode for the connection. NPG mode allows for larger SAN deployments that aggregate I/O traffic at the NPG switch.
SmartFabric mode
This scenario shows attachment to an existing FC switch infrastructure. Configuration of the existing FC switches is beyond the scope of this document.
This example assumes that an existing SmartFabric has been created and is fully operational. For instructions on creating a SmartFabric, see SmartFabric Creation.
To configure NPG mode on an existing SmartFabric, the following steps are completed using the OME-M console:
- Connect the MX9116n FSE to the FC SAN. CAUTION: Ensure that the cables do not criss-cross between the switches.Make sure that chassis are in a Multi-Chassis Management group. For instructions, find the relevant version of the User Guide in the OME-M and OS10 compatibility and documentation table.
- Define FCoE VLANs to use in the fabric. For instructions, see Define VLANs for information about defining the VLANs.
- If necessary, create the Identity Pools. See Create identity pools for more information about how to create identity pools.
- Configure the physical switch ports for FC operation. See Configure Fibre Channel universal ports for instructions.
- Create the FC Gateway uplinks. For instruction, see Create Fibre Channel uplinks for steps on creating uplinks.
- Create and deploy the appropriate server templates to the compute sleds. See Server Deployment for more information.
Once the server operating system loads the FCoE driver, the WWN appears on the fabric and on the FC SAN. The system is now ready to connect to Fibre Channel storage. See Dell PowerStore 1000T for setting up storage logical unit numbers (LUNs).
Full switch mode
This section contains the Full Switch mode switch configuration of MX I/O modules in NPG mode. Configuration of the existing FC switches is beyond the scope of this document.
To configure MX IOMs in Full Switch mode, Follow the steps mentioned below to configure MX IOMs through CLI:
- Verify the MX9116n FSE is in Full Switch mode by running show switch-operating-mode command.
- Connect the MX9116n FSE to the FC SAN. CAUTION: Ensure that the cables do not criss-cross between the switches.
Once the server operating system loads the FCoE driver, the WWN appears on the fabric and on the FC SAN. The system is now ready to connect to Fibre Channel storage. See Dell PowerStore 1000T for setting up storage logical unit numbers (LUNs).
Run the following commands to configure the switch hostname, OOB management IP address, and OOB management default gateway.

Configure the port group for the FC interfaces used to connect to storage. In the deployment example here, port-group 1/1/16 is configured for breakout from 1x64 GFC to 4x16 GFC.
MX9116-B1 | MX9116-B2 |
|
|
Configure VLTi on ports 37 through 40 on the MX9116n FSE. This establishes the connection between the two MX IOMs.
MX9116-B1 | MX9116-B2 |
|
|
For each IOM, define the VLANs and virtual fabrics. The global feature fc npg command enables the switch in NPG mode. Create FCoE VLANs and create vFabric for SAN.
MX9116-B1 | MX9116-B2 |
|
|
Configure the IOMs FC uplink connections to the existing FC switch. In the deployment example here, FC ports 1/1/44:1 and 1/1/44:2 are configured for upstream FC switch connections.
MX9116-B1 | MX9116-B2 |
|
|
Configure the IOMs ports connected to MX Compute sleds. In the deployment example here, ports 1/1/1 and 1/1/3 are configured for downstream connections.
MX9116-B1 | MX9116-B2 |
|
|
Uplink Failure Detection, or UFD, is recommended on all server-facing interfaces and upstream interfaces.
