With vSphere 5.5 Vmware has introduced VM storage policy, but I am not able to find any specific API's in the vSphere web services SDK to find out any specific details about the Storage policy.
Storage policy based management is the next generation of storage porfile feature. Is Vmware going to provideany API for this feature.
Also Vmware supported assinging tags with any managed object from VSphere 5.1. I also unable to find any methods to create\update tags of any object.
