That rule only applies to zAAPs and (according to the press release) zIIPs, not the other types of engines. Using a System z9-109 as an example, all of these configurations are valid: 0 CPs, 54 IFLs, 0 ICFs, 0 zAAPs, 0 zIIPs, 0 extra SAPs 8 CPs, 12 IFLs, 1 ICF, 8 zAAPs, 8 zIIPs, 1 extra SAP 2 CPs, 8 IFLs, 3 ICFs, 2 zAAPs, 2 zIIPs, 3 extra SAPs and so on. As you can see, you can "double count" the CPs for zAAP and zIIP purposes. In other words, the rules are: zAAPs <= CPs zIIPs <= CPs but these rules are independent of one another. On the z890 (where zAAPs are relevant) a subcapacity CP counts. For example, you can configure a z890 Model 210 (a model with two CPs running at slowest possible speed) with two full zAAPs. (The zAAPs always run at maximum hardware speed, as with the other speciality engine types.) The z890 has extra interesting and attractive Java economics, to say the least. - - - - - Timothy F.
