You can interactively install ESXi on all the hosts that will form the first cluster in the management domain, then you configure the management network, DNS, NTP, and SSH services. You can use the same process to add more hosts to the management domain later, or to install and configure hosts for VI workload domains.
Download the ESXi ISO from My VMware. For the supported ESXi version, see the Bill of Materials (BOM) section of the VMware Cloud Foundation Release Notes. If the required version of ESXi does not have an ISO available on My VMware, you can create one. See Create a Custom ISO Image for ESXi.
Make sure that you have a host machine for SDDC access. You use this host to connect to the data center and perform configuration steps.
Verify that you have the completed Planning and Preparation Workbook.
