Val is trying to sell NVMe in a FAS box because it it's "somehow better".
Reality is NVMe is better without the FAS. Not because of the flawed technology, but from a marketing perspective.
Clustered Ontap and FAS have left such a sour taste in the customers' mouth, so that Netapp had to buy Solid Fire.
Think of SolidFire as one of those edible food containers. You can eat it if you cannot find a rubbish bin, but the real goodness is inside (NVMe).
