In the newly released vSphere 6.0 there is a nice new feature called VVol, this is a feature that's has been talked about for a long time.
But before you implement this, you should check if it interoperability with features or other products that you are using.
VMware has made a KB. with there interoperability: http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=2112039
You should also check third part product interoperability with this feature.
