Implement and Configure NSX Controllers
NSX Controllers are the heart and soul of your control plane. They are the central control point for any logical switches in the environment. We want to deploy an odd number of controllers (1,3,5). I would suggest deploying 3 but you can get away with 1 if its in a lab. Obviously, a single controller will not afford any availability if it goes down.
Step 1. From Networking and Security, select Installation ensure you are in the Management tab.
Step 2. In the lower pane, use the green plus to create a new NSX Controller Node. Fill in the necessary information, including the IP Pool you made in the previous section. Create a password for it and click OK to deploy your first controller.
Step 3. Repeat steps 1 and 2 for however many nodes you wish to deploy.
Step 4. Set up DRS Affinity Rules to keep the controllers separated to different hosts for availability concerns.
