If you were running rails inside of Torquebox you could make use of the Infinispan Data Grid (http://infinispan.org/) to cache your views. It's underlying linear scalability mechanism is far more mature than Redis Cluster, and it's deployment story is quite nice. You won't get all of the data structures that Redis provides of course, but if all you need is a great cache, and you're already on JRuby then this could be a better fit for your loads.
