Now we go enable vSAN.
To enable vSAN browse to the appropriate cluster in the vSphere client and click the Configure tab. Expand vSAN and select Services, vSAN is turned off by default so click Configure.
Select the vSAN configuration and click Next.
You can enable Deduplication and Compression for your virtual SAN cluster.
Under Claim disks page select the disks to use in the vSAN configuration and click Next.
Configure any required fault domains here and then click Next.
Review the Virtual SAN settings.
The deduplication and compression can be configured after initial setup. The vSAN menu options in the cluster Monitor tab also provide a number of good monitoring tools and dashboards.
