DB Server load

[nichele]

Hi All,
I would like to ask to you, how many connections a db server can handle. I know the question is not so easy, and actually I don't want to known a "number" but something like:
- up to 100 connections: small load, low entry server is enough
- up to 200 connections: the db server starts to sweat, you need a dedicated medium server
- up to 300 connections: hard work, dedicated server
- up to 500 connections: hard work, dedicated high level server

I would like just to understand when we can talk about small/medium/high load.

Thanks
