I must respectfully disagree. It is not "stupid" marketting by IBM. It is "smart" marketting by IBM. Why? Because although IBM started the "tiered pricing" it is now endemic in the market. IBM is trying to allow companies to legally upgrade their CPU power without getting hit for software upgrade fees by other companies. The original "speciality" engine was the IFL (or was it the CFL?). Since IBM wanted people to use Linux on zSeries, they needed some way to give companies a way to run Linux on the same CEC as z/OS, et al. without getting bushwacked by software vendors. The IFL was a clever way to do that. Based on the success of the IFL, IBM determined that other "speciality engines" could be used in a similar manner. Of course, exactly what can run on these engines is critical. If an OEM could say that their "standard" code might run on a speciality engine and therefore require a fee for said engine, then demand for such an engine would decrease. The zAAP, I'm convinced, was created simply to make it cost effective to run Websphere/Java (Websphere is licensed software which is revenue to IBM) on the zSeries. It allowed more people to use Websphere on the zSeries while perhaps stopping or slowing a migration of that workload to another CPU architecture (such as x/i/pSeries). The zIIP is likewise "smart marketting" in order to drive sales of DB2. I am wondering when some <elided> vendor will add just a bit of Java to an otherwise "legacy" system and then demand software fees based on zAAPs in addition to "normal" CPs. However, I do agree that the entire "tiered pricing" is a millstone on the zSeries. I understand the why of it. But something better is required so that a company can run cost effective software while the software vendors make a reasonable profit. Unfortunately, I don't like anything that I've seen as a proposed replacement. <sigh> Our Windows brethen are just begining to see this sort of pricing as well. It is not as endemic, but as Windows (and other) platforms start taking over mission critical duties, the software vendors will scent the money and start looking to profit.
