Scaling Workload Domain in VMware Cloud Foundation

When you spin up a brand new SDDC using VMware Cloud Foundation, minimum number of hosts that are needed in Management Domain and VI Domain are 4 & 3 respectively. You can scale up Management domain up to 8 hosts and VI domain to 64 hosts.

Before scaling up the workload domains, we need to commission the host first and add it to vCF inventory. To add new hosts to inventory, we need to create a new network pool or expand the default network pool created during bring-up.

Once network pool has been created, you can start commission of new hosts by navigating to SDDC-Manager > Hosts and click on “Commission Hosts” button
