Really large installations

[dramsey]

I'm working on a system for a customer that requires forum functions. The problem is that their site is very large-- as in "over a million users" (although not all will be on the forums at the same time). Still, I think that just one of the customer's dual-Xeon servers won't be enough to handle all the forum traffic.

The customer is experienced with MySQL deployments, replication, etc. so the database side of things is not a problem. Is it possible to run multiple copies of vBulletin accessing a single database? This would not be a case of each vBulletin instance supporting different forums; it would just be an attempt to load-balance potentially large forum loads across multiple copies of the software.

As long as vBulletin uses transacted database writes where appropriate, I think it should work. But does anyone know for sure?
