The NSX-T components are installed when the first VxRail cluster is added to the first NSX-T VI WLD. The SDDC Manager deploys the NSX-T Managers in the management workload domain, assigns an IP address to each NSX-T Manager virtual appliance and a virtual IP, and configures the VI WLD VxRail cluster to be used for NSX-T services. The following list highlights the major steps that are performed during the deployment process:

1. Deploy NSX-T Managers in Mgmt WLD VxRail cluster.

2. Create anti-affinity rules for the NSX-T Managers.
3. Set VIP for NSX-T Managers.
4. Add VI WLD vCenter as a Compute Manager.
5. Assign NSX-T license.
6. Create Overlay Transport zone.
7. Create an Uplink profile.
8. Create Transport Node Profile.
9. Prepare the hosts in the VxRail cluster for NSX-T.

Note: No additional NSX-T Managers are needed when a second NSX-T based VI WLD is added. However, starting with VCF 4.0, you can deploy a new NSX-T domain for each WLD if that is a requirement, 1:1 NSX-T for each VI WLD.

A new feature in VCF 4.0 allows NSX-T Edges to be deployed using automation for the VI WLDs using SDDC Manager. This allows the Edges to be automatically deployed in a consistent fashion per VCF guidance.

The following figure shows the components that are deployed in the MGMT VI WLD after a VI WLD has been deployed and two VxRail clusters have been added to the VI WLD. It shows the two Edges in the first VxRail cluster of the VI LWD that can be deployed using Edge automation feature in SDDC Manager.
