If you require synchronous replication and your queries are conducive to it there is MySQL Cluster. You might get some of the functionality you want with DRBD (but write performance hits) and MySQL, which is supported officially by MySQL, or through the use of circular replication with a pair of masters in MySQL as Ivan mentioned. This type of configuration can also be managed using the Multi master master (<a href="http://code.google.com/p/mysql-master-master/">http://code.google.com/p/mysql-master-master/</a>) project. If you require support Percona will provide support for that project as well. <br>

</div>You can set up MySQL as master1-slave2 <==> slave1-master2. That works<br>
sort of like master-master replication.<br>
