Both MySQL Cluster and DRBD replicate data synchronously. MySQL Cluster leverages a shared-nothing storage architecture in which the cluster can be architected beyond an Active/Passive configuration. DRBD operates at a much lower level within the stack, at the disk I/O level. For a comparison of various high availability features between these two options, please refer to FigureA.1, Availability comparison.
