We are planning to start using Cassandra Cluster with 3 nodes.
Can we use shared storage (SAN) for all Cassandra nodes or does each node needs to have their own local disk?

Hey Bruno,
Requirements set by cassandra recommend to avoid shared storage such as SAN for performance reasons. It is better to give each server their own disks.
