Peter, Most large (FSVO "large") shops can easily justify the HW cost of the specialty engines due to *real* SOFTWARE dollar savings. Without these engines and their lower price per MIP, the usage reverts back to the more expensive "$$ per MIP" general purpose CPs.
The ICFs, the IFLs, the zAAPs and soon, the zIIPs ARE definitely making an impact in deferring acquisition of regular CPs, providing benefits for JAVA, z/Linux and multi-platform workloads AND MOST IMPORTANTLY, keeping the mainframe platform viable! I am not concerned about PR/SM's ability to manage the current pools or any new ones that may be introduced in the future. I would be concerned trying to run web services (JAVA), etc. on the mainframe WITHOUT the cost-effective $$ per MIP of the specialty engines. The total cost of ownership would be through the roof!

IMHO, it's just plain stupid marketing driven nonsense. z/OS MVS has proven to be superior in managing very diverse workloads with a single pool of processors. As of now it has to manage three processor pools, three work queues,... I wonder what the next "speciality" engine (what a terribly misleaging term) will be. Wrong approach, IBM.
