SFS has two profile personalities:
Note: The L3 Fabric personality is required for new SFS deployments. The L2 Fabric is not supported on any new deployment.
The L3 Fabric personality was introduced in OS10.5.0.5. This personality enables users to deploy SFS in a single rack and expand to multirack as business needs evolve.
The L3 personality automatically builds an L3 leaf-spine fabric, facilitating a faster time-to-production for hyperconverged and private cloud environments, while being fully interoperable with existing data center infrastructure. For information about building the SFS L3 Fabric and supported switches, see the guides that are listed in References.
Note: Unless otherwise specified, statements about SmartFabric behavior and features in the following section apply only to the L3 Fabric personality.
