You should also be careful using large amounts of RAM with Cassandra. RAM is great for caching the data in SSTables, but giving the JVM too much heap space is counter-productive. Don't give the JVM much more than 12 GB of heap space, otherwise garbage collection will take too long and hinder performance. This is another reason why having more smaller nodes is better in Cassandra.
