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.
CAUTION: Do not connect any new switches in SmartFabric mode to the fabric until the preferred master settings are validated on the existing and new switches. This is covered in the Verify preferred master setting before fabric expansion section of this chapter
Note: SFS supports up to 20 switches and eight racks in the fabric. For more information, see the Dell EMC Networking Solutions Support Matrix .
