That's a big upgrade About 4x. >we abandoned our consolidating project on the mainframe. >The price is, at least for a small company like us, too high, >and doesn't take into account the higher sw licence costs which >would come along due to more MSUs. You might want to consider upgrading to a z9 BC or a small z10. a 2097-401 will give you about 30% more compute power with just an increase from 26 to 27 MSU. It's a marketing thing. > >Are there guidelines, tools, books, etc. which would help us to >estimate whether 3 or 4 CPs (i.e. 2086-350 or 2086-440) >less fast would still improve our performance compared with 2 >fast CPs like in the 2086-270 ? You have a 26 MSU machine. Your first plan was to increase it to 107 MSU. Now you are talking about either 74 or 62 MSU. It sounds like you are not very sure of your needs. > > >In other words: better more (slower) CPs of fewer (faster) ones ? >What does it depend on ?
