MySQL HA

Reading this article today, about MySQL HA. What it takes:
  1. Replication between the MySQL databases
  2. Hearbeat between the two MySQL servers: requires a serial and an ethernet interconnect. The heartbeat configuration point includes: failover policy and authentification.
  3. One virtual IP address to share between the server, through which the application server will talk to the database.
One comment in the afore mentionned link indicates that DRDB could be of some interest -- DRDB allows you to mirror partitions at the block level over the network.
