Well - if you assume 1 stream/device you will end up with 512 as this is the absolute maximum number of streams per data zone, implied by the server parallelism.

At least it was. Accidentally, i found out that this number has silently been doubled to 1024 with NW 8.1.

As not all streams happen at the same time, you may certainly use more of them too   But even with 32 per datazone you would go way beyond healthy mind approach.  I can imagine that in some corner of this planet some company ended up being fed up with their central IT so each department ended up buying their own infra (storage, hosting), but certain things remained shared infrastructure (eg. backup application) so you may end up with number of small or average DDs - depending on current strength of star wars.  Even so, I doubt one would end up with more than 10-20 DDs (where higher number would depend on replication boxes).

This is true and this where you will find well defined limit too (was it 8? It might depend on DDOS as I believe that has increased in 5.3./5.4). Actually, with it is not only number of active mtrees, but streams that will set you back if you have heavy loaded and populated datazones.

I don't think such limit exists (at least not directly).
