Ontap 9 - 8 Mode - c Mode
Just to be pedantic... I bet the customers are queuing up to be the guinea pig. Just like they did with FlashRay.
Fun aside - calling it Ontap 9 is the smartest thing I've seen NetApp do since inventing snapshots.
It doesn't matter if Ontap 9 is just as half baked as 8, but getting rid of that cDOT / cMode nonsense will probably slow down the damage their marketing team has done.
