The one thing that I think is decidedly true is that the plethora of IBM pricing metrics makes it very difficult for customers to understand and optimize their costs. Of course that may be intentional--IBM needs to have their revenue stream of course.
On the other hand, at least IBM is fairly transparent about their pricing, at least for MLC software. The ISVs, not so much. Transparency is good regardless of how complicated it is to figure out and regardless of whether or not we like the final number. At least we can predict that number--at least until we're surprised by some nuance in the rules that we had missed. Which leads us back to the issue of things being too complicated. Regarding the lack of usage of sub-capacity VWLC, wasn't it only with the z10s that Group Capacity Limits became available? Before that there wasn't any good (built-in) way of controlling the overall usage and so it was quite easy for your R4H to hit very near 100% at *some* time during the month. GCL now gives us a way to ensure the R4H doesn't go over our defined limit just because somebody wrote some bad code or we needed to do a large testing cycle or some such. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
