Re: IBM 2066-002 Adding Spare CP as IFL
I understood the performance implications, this was basically a functional POC and at this point I don't see us moving ahead on this type processor. The 2066-002, on the floor, was picked as a starting point. I'm not involved in the haggling part of the process but I'm sure the necessary individuals are already working on other potential opportunities.

Re: IBM 2066-002 Adding Spare CP as IFL
Patrick, I'm not sure of all the details, but we recently retired our 2066-002. We had two GP processors and 1 IFL active, so it's a supported configuration. IBM or a business partner should be able to help you with the configuration details. As others have pointed out, don't expect much out of this other than being able to bring up a functional system. We didn't have much memory to give that LPAR and our open systems group were very quick to point out that the IFL was a dog and why would anybody want to run there. It took the z9 upgrade to start changing minds, but a lot of the damage was already done in terms of perception and expectations. Bottom line: be careful what you put there and have very clear expectations of what it is and is not before you start.

IBM 2066-002 Adding Spare CP as IFL
Can someone, I the know, save me some look-up time and tell me if I can add an IFL to a IBM 2066-002. My understanding is that this processor type comes with 2 spare CP's. The question now becomes, is the 2066 still supported with regards to turning on one of the spares as an IFL?

Thanks Radoslaw.

All models are enable by microcode. Indeed model 002 has 2 CPs (or GPs depending on nomenclature). However the same machine can be 004, 4xIFL, 2CP+ICF, etc. No technical barriers. The only barrier is ...IBM. Any change in z/800 can be price ineffective or simply impossible due to out of marketing. -- Radoslaw Skorupka Lodz, Poland -- BRE Bank SA ul.

If you get your POC started on the z800 make sure that everyone has the right expectations. The z800 is no speed demon. At ~192MIPS each, these IFLs are going to be downright slow.
