You attach a vCenter Server instance so that the vCenter Server resources become available for use by vCloud Director. After you attach a vCenter Server, you can assign its resource pools, datastores, and networks to a provider virtual data center.

Starting with vCloud Director 9.7, after you attach a vCenter Server instance, you can also create a Software-Defined Data Center (SDDC) that encapsulates the entire vSphere infrastructure. An SDDCs includes one more SDDC proxies as access points to the underlying vSphere environment.

Note: With the vCloud Director Web Console, you can attach a vCenter Server instance only together with its associated NSX Manager instance. For information about attaching a vCenter Server instance alone and registering an NSX-T Manager instance, see vCloud Director Service Provider Admin Portal Guide or vCloud API Programming Guide for Service Providers.


An instance of VMware NSX® is installed and configured for vCloud Director. For more information, see the VMware vCloud Director Installation and Configuration Guide.
