For environments requiring NSX virtual networking, you must install and configure NSX, including integration with the vCenter Server, before deploying HCX Manager.
In the destination environment, the NSX Manager must be installed and integrated with the vCenter Server. For a list of supported NSX versions, see the VMware Product Interoperability Matrix.
The NSX Manager must be registered during the HCX Manager install with the admin user.
If the NSX Manager IP or FQDN uses self-signed certificates, it might be necessary to trust the NSX system manually using the Import Cert by URL interface in the HCX Appliance Management interface.
HCX requires an NSX configured with an Overlay Transport Zone.
When NSX-T is registered, both Overlay and VLAN segments can be used during the Network Profile creation.
When NSX-T is registered, both Overlay and VLAN segments can be used during the Site Resources Profile creation.
In cross-vCenter NSX environments, the HCX is connected to each vCenter Server and the Primary or Secondary NSX Manager, respectively. The HCX system connected to the Secondary NSX Manager must also connect to the primary NSX Manager in the provided field. This configuration is required for Universal Logical Switch extension.
In NSX-T deployments, the HCX supports integration with networking objects created with the NSX Simplified UI/API only.
Deployment of the HCX in environments with multiple Data Centers prepared for NSX and a single vCenter (sharing transport zones and datastores) is not supported.
The Network Extension service has additional NSX requirements. See Requirements for Network Extension.
