Racks
Racks are a design construct where the details of how top-of-rack switches connect within the infrastructure are defined. This includes redundancy models and how servers and other devices connect with the fabric. Apstra includes several predefined Rack Types with various characteristics in-place. Feel free to explore different Rack models by navigating to Design>Rack Types in the menu ribbon on the left side of the server UI. Click the name of these Rack Types to see their details. You will define two rack types in these exercises. One is a single switch with a single-homed server. And the other is a redundant pair and has a combination of dual-connected and single-connected servers. Let’s proceed to creating them now.
