I don't know how to compress almost 30 years of experience in Capacity/Configuration/Performance Management into a single reply. But, it is a basic understanding of what your workload is, how the various components interact, seasonality, tracking, constant revision of forecasts, analysis of announcements, LSPR, zPCR, understanding of the relationships between existing models within and without the same processor family, along with experience and gut instinct, among other things. Also, you should have the answer ready before the question is asked. - Ted MacNEIL [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
