I’ve seen customer love GX; like UZ Leuven.

You could try GX...

I have 17.3TB and a 20.73TB volumes (after Formatting, after WAFL...i.e. USEABLE)

Not sure (yet) how large these can grow, but they are striped aggregates across two heads
(soon to be four!).

In my opinion (as a 12-year customer), the 16TB limit is the number one
deficiency in NetApp software at the moment, and perhaps their biggest
deficiency ever.  I would be very surprised if they weren't losing
customers over this issue.
