Is it possible that Gartner was using older LSPR ratings? IBM does not publish MIPS ratings (although the published PCI is curiously close to others published MIPS ratings)
PCI/(MIPS) tends to change depending on the LSPR test version as well as OS level. If possible, get them to use IBM published MSUS (Software MSU not Hardware MSU). That is the only number you can prove via SCRT reports even if it is as meaningless as MIPS. -------------------------------------------------------------------------- This email message and any accompanying materials may contain proprietary, privileged and confidential information of CIT Group Inc. or its subsidiaries or affiliates (collectively, "CIT"), and are intended solely for the recipient(s) named above.

Some of out vendors are using Gartner MIPS Rating as the base for software costs calculations. I have noticed that prior to Z196 MIPS Ratings the Gartner MIPS number significantly differed from IBM's LSPR / Sherill Watson CPU Charts (which is also based on the LSPR data). On Z196 Garner changed their calculation method to be based on the LSPR values. When upgrading from a Z10 CPC to the equivalent z196 CPC the MIPS differences between the CPC models is bigger then actual based on the Gartner MIPS tables which result in a higher software costs. Gartner MSU's are based on IBM values. For Example: CPC IBM MIPS Gartner MIPS IBM&Gartner MSU's 2097-713 8809 8454 1076 2817-709 8943 8840 1091 ================================================= Diff 134 MIPS 386 MIPS 15 MSU >From the Gartner Z196 MIPS rating table their is note regarding the calculation method change: The base performance that IBM uses to come up with system performance comparisons is the new AVERAGE workload. Gartner will now look at the AVERAGE workload LSPR results as the base of our MIPS calculation. 1. Are you using Gartner or other method for calculating ISV Vendors software costs ? 2. Are you aware to the change in the calculation method and how your organization deals with it? The MIPS difference can result in a major difference in the software costs? ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@bama.ua.edu with the message: INFO IBM-MAIN ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@bama.ua.edu with the message: INFO IBM-MAIN
