Just based on what I was told by a NetApp sales rep. Very glad to hear that this is a supported configuration. It had been explained to me ~6-8 months ago that all-ssd aggregates were only supported by AFF systems, which would not support hybrid or spinning disk shelves, and that if one needed an all-ssd aggregate (flash-cache\pool not sufficient) , adding an AFF HA pair to a cluster was the only way to go

I don't know why you think so. I've been running an 8060 four node cluster with a shelf of SSDs with most of them in an aggregate, along with a couple or three disks (I forget) were setup in a FlashPool. But since we also had FlashCache, it was explained to us that they didn't really work like we thought/wanted, so we just nuked the FlashPools and added the disks back into the SSD aggregate.
