If it's WebSphere Application Server on z/OS, and you can get up (at least for an LPAR) z/OS 1.6 or higher and WAS 5.1 or higher, then you can probably get a whole lot of CPU back with a zAAP on a z9 BC model. Would recommend crunching those numbers, too. For reference, a z800-0A2 is 44 MSUs. A z9 BC Model L04 is roughly the same capacity -- depends on your workload, of course -- and only 36 MSUs. Add a zAAP and you might not need something as large as the L04. If you do need more memory then that costs a bit less on the z9. Another benefit is more precise capacity sizing. You can look at this backwards and forwards. If the z800-0A2 becomes too small as you grow, then the next step up is a -002. But your MSUs increase to a whopping 60. On the other hand, from a z9 BC L04 you can move to a U01 (38 MSUs) or a P02 (41 MSUs) -- just a smidgen more capacity and not that giant leap. This idea also works if your -0A2 is a little too big right now (because the -001 was too small or otherwise not suitable). Please ship your z800 to me. I'd like to put it in my home data center, OK? I'm only half joking. - - - - - Timothy Sipples IBM Consulting Enterprise Software Architect Specializing in Software Architectures Related to System z Based in Tokyo, Serving IBM Japan and IBM Asia-Pacific E-Mail: [EMAIL PROTECTED] ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
