- Log in to the vSphere Web Client. In the navigation pane, choose Host. On the Configuration page, click VMkernel Adapter under Network and create a VMkernel.
- On the Select Target Device page, select DPortGroup-vsan for Select an existing network and click Next.

- On the Port Attributes page, select vSAN and click Next.

- On the Set IPv4 Address page, select Use a static IPv4 address. Set the IP address of the three ESXi hosts to 11.11.12.101, 11.11.12.102, and 11.11.12.103, respectively. Then click Next.

- You can create a vSAN cluster or enable vSAN for an existing cluster. For details, see Creating a vSAN Cluster.
- A disk on each ESXi host is reserved as the local datastore. Other SSDs form a disk group and are added to the vSAN cluster.
- VM disks that have been created on the first ESXi host can be migrated to the vSAN cluster.
