Hi Marius,
I'd encourage you to work with your NetApp SE/TAM and Account Manager on this - where you're considering a 24 node environment, we're absolutely committed to meeting essentially any customer requirement.
The caveat is that the customer requirement should be considering terms of capacity, performance and resiliancy, not raw hardware. Delivering more with less is always better in terms of power, cooling, rackspace, operations and maintenance.
Feel free to reach out to me by message or email to first.last @ netapp.com if you would like me to reach out to our internal teams for you for better engagement
Thanks!
