It's possible to setup large RDBMS clusters. I've certainly done it. Informix's XPS was one of the better approaches before IBM nixxed it.
Get beyond 8 nodes though and the amount of work involved in ensuring your referential integrity becomes quite time consuming. Creating joins at that scale is a fair amount of work.
There are 800-1000 node clusters out there running Cassandra. I would struggle to maintain performance with a traditional solution at that scale.
I've not seen it all though, I would be interested to hear of equivalent deployments in the RDBMS space.
