SFS has two profile personalities:
Note: Dell Technologies requires use of the L3 Fabric personality for new SFS deployments. The L2 Fabric is deprecated and not supported on any new deployment.
The examples in this section use the L3 Fabric personality. Unless otherwise specified, statements about SmartFabric behavior and features apply only to the L3 Fabric personality.
The L3 Fabric personality was introduced in OS10.5.0.5. The L3 personality enables users to deploy SFS in a single rack and expand to multirack as business needs evolve.
The L3 Fabric 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 appropriate documentation in References.
The following figure compares the traditional deployment approach with the new approach:
