From the left navigation pane, select Data Center > Virtualization > Cluster name.
Click the Storage tab.
Click Add.
Configure the parameters, click the icon to select the required shared file system, and then click OK.
Type: Type of the shared storage. Options include Shared-File System and RBD Storage.
