How do cluster nodes communicate with one another?
Cluster nodes can communicate via any of three different protocols: TCP/IP, SHM (shared memory), and SCI (Scalable Coherent Interface). Where available, SHM is used by default between nodes residing on the same cluster host. SCI is a high-speed (1 gigabit per second and higher), high-availability protocol used in building scalable multi-processor systems; it requires special hardware and drivers. See Section 16.7, « Utilisation d’interconnexions haute vitesse avec MySQL Cluster » for more about using SCI as a transport mechanism in MySQL Cluster.

Where available, SHM is used by default between nodes residing on the same cluster host; however, this is considered experimental. SCI is a high-speed (1 gigabit per second and higher), high-availability protocol used in building scalable multi-processor systems; it requires special hardware and drivers. See Chapter 11, Using High-Speed Interconnects with MySQL Cluster, for more about using SCI as a transport mechanism for MySQL Cluster.
