Hi John,

There is a concurrent connections limit on the DNs that's set to a default
of 4k max parallel threaded connections for reading or writing blocks. This
is also expandable via configuration but usually the default value suffices
even for pretty large operations given the replicas help spread read load
around.

Beyond this you will mostly just run into configurable OS limitations.
