IBM did a great job of positioning these two as so-called "specialty" engines, with the implication that they are somehow better or optimized for running their respective kinds of workloads. Of course the hardware is in fact identical to the regular old engines, at a lower price but with restrictions on what software is allowed to be run. I've advocated calling them "restricted" or "limited function" engines, but of course that wouldn't suit IBM's approach. So yes, Happy Birthday to all kinds of limited function engines!
