To add hosts to the Cloud Foundation inventory, you must first create a network pool or expand the default network pool created during bring-up. If you want to isolate VMkernel traffic (management, vSAN, vMotion, or overlay) across multiple physical NICs (pNICs) on the hosts, you must enable the additional pNICS before adding them to Cloud Foundation.

For information on network pools, see Network Pool Management. For information on enabling additional pNICs, see Enable Additional pNICs on Hosts.

You then commission hosts to Cloud Foundation. During the commissioning process, you associate hosts with a network pool. Commissioned hosts are added to the Cloud Foundation inventory. You can add these hosts to the management domain or to a VI workload domain. When a host is added to a workload domain, an IP address from the network pool's IP inclusion range is assigned to it.

See VMware Configuration Maximums for information about the maximum number of hosts per SDDC Manager instance.
