I used to work at a site that was using the Seimens (formerly SMS - Shared Medical Systems) software. We upgraded our software from the former "Independence" application suite which was using system 2000 as a database manager alongside the CICS application. At that time, we were running a 2 CPU machine and the load was fairly well balanced between the CICS and the S2K address spaces. When we upgraded the application to "Invision" which moved the data from the S2K database to VSAM files running on CICS, the main CICS TCB was pegging one of the CPUs and the other was way under-utilized. When we upgraded our CPU, we upgraded to a larger single engine machine to give more CPU to the CICS TCB. I would "assume" that Siemens is no longer quite so single-TCB dependent, but who knows.
So, there may still be a requirement for larger single CPU applications if that is all that is running on the machine. My $.02.

But - I'd be looking *real* close at RMF. Ask your vendor to run some comparative configurations for you if you want a "warm and fuzzy" feeling about the upgrade. Maybe even have a play yourself with something like zPCR - have a wander around the techdocs site.
