Our Delphix environment is provisioned on a thin provisioned backing store. We have followed best practice by allocating VMDKs as thick (eagerzeroed). Is it possible to perform thin space reclamation of zero or deleted blocks within the Delphix Engine VM appliance - to free these blocks on the backend array?

One of the requirement of the Delphix Engine is that the VMDKs should be created with the Thick Provision Eager Zeroed option. This is done for the performance reasons. Once this has been done, as far as I can see you can not reclaim the empty blocks.
