In memory Cache for Java that does not use JVM Heap space [duplicate]

Question

I am looking for In memory Cache for Java that does not use JVM Heap space.

I have looked into EhCache and JCS but both of them uses the Heap.

I want it to be scalable.

You can also consider to use HazelCast In Memory Data Grid solution. I have used it, I would say its one of the best solution I came across.
