<div>If you set up a cluster using ndbcluster tables then some modifications are necessary. Since we use such an architecture, I have written about it here: <a href="http://www.coderintherye.com/drupal-mysql-cluster-ndbcluster-high-availability">http://www.coderintherye.com/drupal-mysql-cluster-ndbcluster-high-availability</a></div>
<div><br></div><div>On that note, there are some issues in core a while back that could use some looking at relating to get ndbcluster support out of the box with Drupal (filed against 8.x): <a href="http://drupal.org/node/703916">http://drupal.org/node/703916</a> and <a href="http://drupal.org/node/391130">http://drupal.org/node/391130</a> </div>

I actually just set something like this up for a client. Master-master<br>
replication works well. The only thing we had problems with is making sure<br>
that uploaded files get replicated to all of the web servers. We ended up<br>
using Dropbox (I know - there's better solutions out there, but we wanted to<br>
put something together quickly).<br>
<br>
Future plans were to implement something like the Andrews File System to<br>
replace Dropbox.<br>
<br>
Thanks,<br>
Cameron<br>
