Hi Antonio, the limit is set by the EMC/Netsight Server, so 3M is the limit their, and 50,000 clients.
If there is demand for something beyond this, it's up to sales/development to entertain the potential for more flows/feature request/future technology etc. We could make a feature request if their was a sales potential/current implementation issue, but a case would need to be started for that to occur, and feature request launched off of that.
