I will agree for true data sharing environments.  But many shops have parallel
sysplexes and don't do any real data sharing.  In those environments 
sharing engines on a CF can be perfectly acceptable - especially with the
speed of a z990 or z9 engine.   It is certainly acceptable for development 
environments also.

So to answer the OP (which is hard to do without more information), you 
can start with a swag based on the relative activity in the different 
sysplexes and look at RMF reports.  For example, 80/20 or 70/30
for production / development.
