Hi,  
I am new to Rally, would like to know if we can use rally to configure the cluster the size. Can we know how much our cluster can handle to the volume of the index?

As far as I know, Rally is not yet able to spin up multi-node clusters. You can however run Rally benchmarks against existing multinode clusters by using the [benchmark-only mode](http://esrally.readthedocs.io/en/0.5.3/pipelines.html).
