I am experimenting most suitable cloud scheme. Cluster has three status Green, Yellow and Red. It is good to have Green cluster. I did so many experiments to choose this and finally get to the conclusion. It is always good to have N = R + 1. Where N is number of nodes and "R" is Number of replicas. So if you want to have 3 replicas than you should go for 4 nodes to keep the cluster status Green Which seems to me good. I'm not sure if i am explaining in the right direction. Suggestions from someone experienced are highly appreciable. Thank you. ---

Basically yes, also note that you can change number of replicas dynamically.

Yes, but note that you should really state: N \> R + 1. You can have 10 nodes, with an index that has 5 shards and 2 replicas, and still benefit from it as the shards will balance between the 10 nodes.

Thanks for this wonderful piece of software. Nodes are simply directly proportional to replicas. ---
