It's hard to understand where Shane is coming from sometimes. He is so vague. When we upgraded to the z9 from a z800, the biggest shock was HSA. 1.4 Gig for HSA and no warning it would be that bad ??? I read about its impact, but never imagined it would be so much. Wiped out a whole LPAR I had planned. I concentrated on reviewing a paper called "Moving to fewer and faster CPU's" (or something like that) when we originally went to the z800. That has a good discussion of the concerns at a level my simple mind can understand. I just wanted to ensure I didn't short something I cared a lot about. All-in-all, our upgrade went well. I'm still learning to optimize the configuration, but you'll be able to hide most of your transgressions behind the increased performance. Moving from the z890, you won't have major conversion concerns either. Considering the jump you're making, happiness will abound. ---------------------------------------------------------------------- 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
