title: Where does Redis store the data
body: <p>I am using redis for pub/sub as well as for server side cache. I mean my app server has redis server running as one process (functioning as a cache as well) . I have several thin clients  (running redis client) connected to this app server in pub/sub mode. I would like to know where redis stores the cache data ? in server alone or there will be a copy in the clients as well. Also is it a good idea to use Redis in this fashion if there are close to 100 redis clients connected to server through pub/sub channel. </p>
  
  <p>Thanks</p>
