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 Mgmt WLD. It assigns an IP address to each NSX-T Manager virtual appliance, and it assigns a front-end virtual IP address for those appliances. After assigning those addresses, SDDC Manager configures the VI WLD VxRail cluster to be used for NSX-T services.
The major steps of the deployment process are as follows:
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.
Beginning with VCF 4.0, NSX-T Edges can be deployed using automation for the VI WLDs using SDDC Manager. This feature allows the Edges to be automatically deployed consistently 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 NSX-T Edges in the first VxRail cluster of the VI WLD that can be deployed using Edge automation feature in SDDC Manager.
