I'd also very much like to see ADP available across the range. It's quite expensive without it if you've got a filer with say 6T disks and it's only going to get worse for systems focusing on capacity.
For FAS8000 ADP is only for All Flash. You can create StoragePools for FlashPool if using hybrid aggregates though...but root volume partitioning is not available on 8000 right now if you have HDD (SAS and SATA). FAS2500 does however allow it for HDD.
