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, assigns an IP address to each NSX-T Manager virtual appliance and a virtual IP, and configures the VI WLD cluster to be used for NSX-T services. The following list highlights the major steps that are performed during the deployment process:
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 VVD guidance.
The following figure shows the components that are deployed in the MGMT VI WLD after a VI WLD has been deployed and two clusters have been added to the VI WLD. It shows the two Edges in the first cluster of the VI LWD that can be deployed using Edge automation feature in SDDC Manager.
