This is the generic discussion that most people can follow or even find intuitive. So despite the historical references in your post, that situation only applies to z/VM 5.2. At the risk of teaching Granny, the point we tried to make in this thread is that for some configurations, because of restrictions in CP, not all 32G can be used, but primarily only 2G is being used. Using 2G out of 32G is only marginally better than using 2G out of 16G. For historic reasons the moves between the 2G and the rest turn out to require paging, which is less painful when expanded storage can be used.
