VxRail 7.0.400 introduces an option that opens up new functionality for SFS with VxRail deployments. This new option allows you to choose whether automated SmartFabric switch configuration is enabled or disabled during VxRail deployment.
When enabled, the automation configures VxRail networks on the SmartFabric switches during deployment. However, it limits the ability to support SFS with VxRail in a wide range of network environments after deployment.
Starting with VxRail 7.0.400, the VxRail Deployment Wizard provides an option to set Automated VxRail Switch Configuration to Disabled. Dell Technologies recommends setting the automation to Disabled, as is done in this deployment guide. The SFS UI is used to place VxRail node-connected ports in the correct networks before deployment instead. With automated switch configuration disabled, the VxRail Deployment wizard bypasses the switch configuration step. The advantage of bypassing this automation during deployment is that SFS and VxRail can be supported across a wider array of network environments after deployment. It will also simplify the VxRail upgrade process in the future.
Disabling automated switch configuration only affects SmartFabric switch automation during VxRail deployment, or when adding nodes to an existing VxRail cluster after deployment. Automated switch configuration after VxRail deployment is still supported by registering the VxRail vCenter Server with OMNI. Networks that are created in vCenter are automatically configured on the SmartFabric switches by OMNI.
