CAUTION: Do not connect any new switches in SmartFabric mode to the fabric until the preferred leader settings are validated on the existing and new switches. This is covered in Verify preferred leader setting before fabric expansion.
Note: If you do not plan to expand to multirack at this time, skip to Add a second VxRail cluster.
In this chapter, the SmartFabric is expanded to a second rack with the addition of Spine1, Spine2, Leaf2A, and Leaf2B. After the fabric is expanded, VxRail node 4 in Rack 2 is added to the existing VxRail cluster. These items are outlined in red in the figure below.
Note: SFS supports up to 20 switches and eight racks in the fabric. For more information, see the Dell Networking Support & Interoperability Matrix.
