VCF 9.0 describes Supervisor networking with NSX as a model whereNSX provides network connectivity to Supervisor control plane VMs, services, and workloads, and where the Supervisor can use either the NSX Load Balancer or the Avi Load Balancer. In the NSX + Avi design, the documentation identifies theAvi Load Balancer Controlleras a core infrastructure element: the Controller “interacts with vCenter to automate the load balancing for the VKS clusters,” and is responsible for provisioning and coordinating Service Engines and exposing operational interfaces.

Also, the Supervisor itself is anchored by theSupervisor control plane virtual machines. VCF 9.0 explains you deploy the Supervisor with one or three control plane VMs, and in a three-zone Supervisor the control plane VMs are distributed across zones for high availability.

Finally, because the requirement explicitly calls for a unified networking/security model throughNSX, theNSX Manager virtual machineis foundational to the NSX-based Supervisor design, as shown in the documented architecture and component descriptions for NSX-backed Supervisor deployments.
