Honestly there isn't enough information about your use case. RBD usage with small IO vs ObjectStore with large files vs ObjectStore with small files vs any number of things. The answer to your question might be that for your needs you should look at having a completely different hardware configuration than what you're running. There is no correct way to configure your cluster based on what hardware you have. What hardware you use and what configuration settings you use should be based on your needs and use case.
