Hi there is indeed a way. Soon there will be two.
At the moment you have to use the vSphere Storage Appliance. For more infos please take a look at this page: VMware vSphere Storage Appliance (VSA) for Shared Storage - United States
And at the moment there is a public beta for a new product called VSAN, that works without an appliance in the new vSphere releases. You can sign up for public beta here: Virtual SAN Public Beta - United States
