DRDB is a _very_ bad recommendation for a production system. DRDB is
unreliable by any definition.
Simply make up the potential fault matrix and you will notice that DRDB will
not provide the safety expected from a failover cluster.
Depending on the kind of applications employed there are many HA features
available on SuSE Linux.
