NSX-T components are not dedicated to a specific vCenter Server instance or vSphere construct. You can share them across vSphere environments in the same physical location.

Although an NSX-T deployment is not associated with a vCenter Server instance, it supports only single-region deployments.

Design Implications


Deploy a three node NSX-T Manager cluster to configure and manage the shared edge and compute cluster and all additional compute clusters in a single region.

Provides support for software-defined networking (SDN) capabilities, such as load balancing, firewalls, and logical switching.

You must install and configure NSX-T Manager in a highly available cluster.


In the management cluster, add the NSX-T Manager nodes to the distributed firewall exclusion list of NSX for vSphere.

Ensures that the management and control plane is still available if a mistake in the configuration of the distributed firewall of NSX for vSphere occurs.
