"PSU" is a *procedure* that you use to apply the Recommended Service Upgrade (RSU). See Chapter 2 of the Service Guide. (IMO, it doesn't deserve an abbreviation.) The term "stacked RSU" is historical. Back in VM/ESA Version 2 the RSU for each component (CP, CMS, TCP/IP, etc.) was orderable separately in addition to a "stacked" RSU that contained all of the most recent component RSUs. In z/VM V3, individual component RSUs were dropped, but the "stacked" moniker persisted. My friends in Development will take it under advisement that perhaps it is time to retire the term "stacked" as it adds no value. "RSU" and "stacked RSU" are the same thing now days. As a reminder, http://www.vm.ibm.com/service/rsu/ is your friend.
