Sorry if my posts yesterday were confusing. I posted as a reply to the 6% post, but realized many would not open that old thread and that I needed to have 2% as part of the subject. So I "replied" again, and did not repeat the content. So here is the content and below that I'll respond to the questions and comments I've received:
---------------------------------- I've done further analysis, now that the LCS_PRICING Interactive Report is updated with the new prices. When viewed not tier by tier, but with a stack of other software products (for which the prices did not change) the increase on the MLC invoice due to the z/OS increase is closer to 2%. As more and more products are added to the software stack, the percent increase will be smaller, as the other products are added to both the before and after totals equally. One customer has shared their analysis with me and for their products and features the monthly impact is approximately 1.8%. My analysis is available at: http://www.sherkow.com/updates/zos_2012_price_increase.html I hope you find this interesting and I welcome any comments or feedback you may have. I can find no other public analysis that shows this effective increase is near 2%. The bottom line is that everyone needs to analyze their own site. Similar to determining which software pricing metrics your site should be using there still are not clear rule of thumbs that work for every site. ---------------------------------- My analysis was with IBM software only, and a very small, completely sub-capacity product set. Adding other products, whether from IBM or from an ISV would lead to smaller and smaller increases. Additional products would minimize the effect of the z/OS increase. The analysis used prices in US Dollars. I did not assume the growth or pricing for CICS, DB2, or WebSphere MQ series. On the linked page above, in the lower portion I describe the actual increases of the version changes. I won't full repost here, but between DB2 V7 and DB2 V10 the increases ranged from 9.5% to 12%. CICS TS V2 through V4 had a range of 11.7% to 14.5%. Again over a range of MSU levels. I did not use zNALC pricing, this was VWLC and AWLC. I could run some zNALC scenarios. However, the effect of the z/OS increases would be even smaller with the very large zNALC discounts. In the US z/OS did have a price increase effective 1 April 2009 (see http://ibm.co/Dec2008-308-887-increases). I know as I typed those prices into the LCS pricing tables. For example the VWLC tier of 176 to 315 MSUs was announced on 10/3/2000 as $110, on 4/1/2009 this increased to $113 and now on 4/1/2012 it will be $120. The lower tiers changed on 10/3/2003 with the mainframe charter; some tiers were raised and some lowered to as the initial z/OS announcement had a minimum starting base of 45 MSUs. Thanks for all the comments and feedback, these are all good points in the discussion! Al Sherkow, I/S Management Strategies, Ltd.
