SFS personalities

In SFS-enabled network, VxRail deployment option include L2 single rack or L3 multirack personalities. The table lists the comparison between L2 and L3 fabric personalities:

Table 1. SFS personalities SFS personalities
L2 Single Rack personality	L3 multi rack personality
Single rack network fabric is supported for VxRail clusters. For new SFS deployments, use the L3 leaf and spine fabric personality as the SFS L2 personality is deprecated.	Multi rack data center network fabric is supported that starts with a L3 single rack (L3 fabric profile) and which you can expand to a multi rack solution based on the demand.
Network fabric has two leaf switches in a single rack which you cannot expand.	Network fabric has up to 20 switches in a leaf and spine design that starts with a single rack which you can expand up to eight racks.
All VxRail with SFS deployments from SmartFabric release OS10.4.1.4 to OS10.5.0.5 support configuration with a single pair of leaf switches for VxRail clusters.	All SmartFabric deployments with SmartFabric OS10.5.0.5 or later.
Default uplink and jump host port are created as part of a fabric initialization, which you cannot modify after enabling SFS.	You can create uplinks and jump host port through SFS GUI or OMNI after initial deployment.
Enabled SFS by running a Python script in the OS10 Linux shell.	Enable SFS using CLI, API, or UI.
Existing deployments when upgraded to SmartFabric OS10.5.0.5 continue to run in the L2 fabric profile and L3 fabric capabilities are not available. If you upgrade switches with L2 personality to OS10.5.0.5, SFS operates with the VxRail L2 single rack personality.	Dell Technologies recommends that you enable all new deployments with L3 leaf and spine fabric personality. You cannot upgrade VxRail with SFS deployments to the new L3 leaf and spine fabric personality automatically.
