I was wondering if there was a simple (complete!) guide somewhere lurking on the net on how to scale a WordPress Mu site above the theoretical limit of 32000 blogs created? I understand that the main issue is the nestled uploads directories for each individual blog (yes, each will need uploads).
We are expecting to have many, many more than this after only a few months of site go-live and I want to put the scalability in-place from day 1 so I don't have to reverse engineer anything in the future.
The site I am working on is initially going to run off 2 dedicated servers - server 1 was going to be used to run the Mu site, server 2 is being used for some extra 'non-WP' functionality for the site, but could be used for file storage and to scale some of the Mu site across to).
I have been using WP for over 4 years, but this is my first proper Mu project. Although I have been checking out various pages on the net about this there doesn't seem to be any clear, definitive up-to-date answers for this. More a bunch of gems of knowledge spread around various sources.
If I can't find a solution I may have to go to the darkside (another platform) which is something I REALLY don't want to do as I love WP so much!!
Please - I could really do with some solid advice on this!
