Hi,
We have a few FAS8200s that are using HPE 3PAR for storage, by default the volumes on the 3PAR are thin provisioned to the FAS8200s.
Is ONTAP friendly towards thin volumes provisioned to it from 3rd party arrays ? So if data is deleted on a filer volume will it perform the equivalent of an unmap command to let the array know that blocks can be reclaimed ?
Or is there a way to write zeros to the freespace on a volume/aggregate so that the storage array can claim back space and make the volume thinner ?
Thanks!
