The issue is with whether the Coupling Facility is too slow relative to
the coupled z/OS images. Just to be clear: Not whether the images are on
different speed engines.
However such 'assymetry' is unavoidable when having z/900 and z/ANYTHING
in same parallel sysplex. However, AFAIR, the problem exist when CF
engine is to slow, so having ICF on z/ANYTHING and not on z/900 (do not
forget about redundancy) would not make negative effects on CPU (CP-type
CPU). From the other hand - z6 CPU in z/ANYTHING will be even cheaper... <g>
