If you purchase a zAAP or zIIP and only use it 10%, you haven't hurt your software bill, but you've spent money on a engine you aren't taking advantage of (albeit less than a GP). I don't know what the break even point is, but I'm sure it's highly variable depending on the mix of software at your shop. I think I have heard an ROT of at least 25% utilization. I don't pay as close attention to this sort of thing since I don't manage the budget. :-) Mark -- Mark Zelden Sr. Software and Systems Architect - z/OS Team Lead Zurich North America / Farmers Insurance Group - ZFUS G-ITO mailto:[email protected] z/OS Systems Programming expert at http://expertanswercenter.techtarget.com/ Mark's MVS Utilities: http://home.flash.net/~mzelden/mvsutil.html ---------------------------------------------------------------------- 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
