NSX-T Manager implements both the management and central control planes in an NSX-T system. For dynamic routing between the tenant workloads in the domain, you deploy a pair of NSX-T Edge nodes.

NSX-T Manager also provides the user interface and REST APIs for creating, configuring, and monitoring NSX-T components in a workload domain, such as segments, gateways, and security policies.

For high availability of the management and control planes, you deploy a cluster of three NSX-T Manager nodes.
