title: redis cluster total size
body: <p>I have a quick question about redis cluster.</p>
  
  <p>I'm setting up a redis cluster on google cloud kubernetes engine. I'm using the n1-highmem-2 machine type with 13GB RAM, but I'm slightly confused how to calculate the total available size of the cluster.</p>
  
  <p>I have 3 nodes with each 13GB ram. I'm running 6 pods (2 on each node), 1 master and 1 slave per node. This all works. I've assigned 6GB of RAM to each pod in my pod definition yaml file.</p>
  
  <p>Is it correct to say that my total cluster size would be 18GB (3 masters * 6GB), or can I count the slaves size with the total size of the redis cluster?</p>
