Barbara, In your note below you left out the number of engines as part of the equation for hardware MSU. It also sounds as if you want to compute the hardware MSU for a series of models and show then as bars on the same chart as your actual data. The best way to do that, in my opinion, is to use service units all the way around. You can do that by converting time back to service units and going forward.
Please note that this will not give good numbers or anything close to them if you change model families, such as from a z10 to a z196. It is only good within a single family. Hope this helps, Jim Horne -----Original Message----- From: IBM Mainframe Discussion List [mailto:[email protected]] On Behalf Of Barbara Nitz Sent: Wednesday, July 06, 2011 5:08 AM To: [email protected] Subject: Re: How many CPU seconds can I consume per 10minutes? Thanks for all the suggestions. I guess I didn't make myself clear enough when I asked the question. I am NOT looking to show anything normalized, quite the opposite. What I do want to show is absolute cpu seconds used, with a horizontal line (bar, minibar, Unselectable Storage Segment :-) ) denoting what the maximum number of seconds achievable would be on the 'smallest' box. I am also NOT talking about an LPAR view (making WLM service levels irrelevant), but rather a view of the complete box, ie. for all lpars on that box using the general CPs. >Check out SMF70MPC/MTC/MCR/MTC/MPC >The "current" set provides the (physical) number of CPs as part of the model >identifier, as well as the MSU rating. We're currently running on a z9, so I cannot yet use these fields. If I understand correctly, then an 'MSU rating' is a number like 339, specifying a capacity of 339MSU. What's the relation of an MSU rating to anything? Found a website where Al Sherkow did the same calculation that I just did: Multiply the SRM constant (as published by IBM- 20592,0206 SU/s) by 3600s. This gets me 74.131.274,16 SU/h or 74MSU per hour. Al calls that 'hardware MSU' (as opposed to 'software MSU', which appears to be the 'MSU rating'. That doesn't help me with my horizontal line, as I have no clue how to relate the 339 MSUs (supposedly available in one hour) to the 74MSU maximum that I computed. Where is my thinking going wrong?
