You can create a vSAN cluster as you deploy vCenter Server, and host the vCenter Server on that cluster.
The vCenter Server is a preconfigured virtual machine used to administer ESXi hosts in a cluster. You can host the vCenter Server on a vSAN cluster.
When you use the vCenter Server Installer to deploy a vCenter, you can create a single-host vSAN cluster, and host the vCenter Server on the cluster. During Stage 1 of the deployment, when you select a datastore, click Install on a new vSAN cluster containing the target host. Follow the steps in the Installer wizard to complete the deployment.
The vCenter Server Installer creates a one-host vSAN cluster, with disks claimed from the host. vCenter Server is deployed on the vSAN cluster.
After you complete the deployment, you can manage the single-host vSAN cluster with the vCenter. You must complete the configuration of the vSAN cluster.
