snapshot size of VM inside datastore


We've got three datastores (LUN attached via FC) with more that 100 VM's in there.

Is it possible to determine somehow the size of snapshots for every virtual machine one by one ? It doesn't matter if it will be done on NetApp side or VMWare.

Re: snapshot size of VM inside datastore

From the NetApp side, no.  To be able to do it from VCenter, there would have to be a "change rate" meter - but even then, it would be ugly.  If it existed, and assuming that it didn't track new data (since only changed and deleted blocks take up snapshot space), you'd have to correlate that change rate somehow with your snap schedule and retention and add up all the copies...
