Notes from the MySQL Cluster High Availability Features talk at the 2004 MySQL User's Conference...
Redundancy between nodes via heartbeat. Redundancy between clusters via replication. In other words, NDB provides local and global redundancy. System recovery for a full-scale shutdown. Hot backup and restore. The architecture in general was designed to eliminate single points of failure.
Lots of diagrams illustrating recovery in various failure scenarios that I can't ASCII copy too easily. Doh!
