Re:

I would respectfully disagree.

pNFS does not stripe data across controllers. Data is distributed, not
striped.
Every node is a metadata server and will redirect the client process to the
node directly holding the volume. No striping.

Maybe you are confusing pNFS with FlexGroups which distributes files across
nodes.
A very long time ago in ONTAP GX, there >>was<< an ability to stripe data
across controllers. That feature was removed upon going to ONTAP 8.0
