Just to complete the loop I've just had confirmation direct from Netapp that R-D2 is supported on mixed storage system. The "all-flash" requirement _only_ refers to the initial shelf/root volume. As long as that requirement is satisfied you can add whatever type of shelves you like. So FAS with a shelf of R-D2 SSDs can totally have SAS or SATA shelves added to it later. Now why they can't spell this out in a TR or communicate in a way that doesn't feel like pulling teeth is a mystery to me...

Root-data-(data) partitions are supported only on all-SSD systems; as you have SAS/SATA disks you cannot use them – at least in supported way.
Thanks for that insight, I really appreciate it. Feeling really let down by Netapp now for them to propose a solution that is unsupported! I will have words :(
