Historically in the i world, prices for software was based on the P level of your processor. The more powerful the P level, the more you would pay and this had implications not only for the initial purchase but also for anytime you upgraded. You would have to check all your software and see which ones you needed to adjust payments on and get a new license key for.
The initial reason for P level pricing, other than trying to just confuse the situation, was to let people get into the i world on the cheap and then charge them more as their usage grew. But it tended to be an annoying reminder that no matter what you do you always end up paying more. Now, however, a number of companies are moving away from P pricing and going to a fixed price and SkyView Partners, makers of premier security products for the IBM i including Policy Minder which helps ensure that your system stays in sync with your security policy once you have set it up, and Risk Assessor that helps you determine what areas you might have security problems in (almost finished but it’s OK to take a deep breath), is now joining that group.
Pricing has been changed to a per partition fixed amount. In addition, you can buy a universal license that allows you to run on as many partitions as you want (even if you haven’t yet set up some of the partitions). And for cloud vendors, there is a plan for SAAS use of the tools for their clients.
For more information on either the pricing or the products (which are very reasonably priced and excellent), you can contact either myself (firstname.lastname@example.org) or J. D. Seal at SkyView Partners (email@example.com).
