Once again, sub capacity pricing to the rescue. The cost is based on the largest rolling four hour average. Short duration spikes don't count for anything.
You set the maximum four hour rolling average on the HMC. And that sets your maximum software price. You could pay less if your consumption does not get that high, but you won't pay more. The hardware will automatically throttle back if the average consumption exceeds your set value. You can change the maximum at any time with a few keystrokes and couple of clicks. Management likes the idea of being able to instantly choose to spend the money to accomplish an important mission, and then drop back to budgeted levels for next month. All with nothing more than a phone call or email to the friendly local sysprog. Or even operator in some shops. We love it. HTH and good luck. -----Original Message----- From: IBM Mainframe Discussion List [mailto:[EMAIL PROTECTED] On Behalf Of Ken Hansen Sent: Saturday, July 15, 2006 9:58 PM To: [email protected] Subject: Re: Sizing (Capacity Planning) a Development Shop or Complex The trouble with development work is that it tends to be unpredictable and spikey. There are typically no SLAs to manage to and often the only guide is complaint. One question is who pays for the processor upgrades ? The developers ? If not, what justifies the need for an upgrade ? The capacity planner or developer complaint ? Your predictive method is pretty much what I would use. Unfortunately developer estimates of future CPU needs can be inaccurate. plus development efforts come and go. This said, you might look at the new IBM z9 BC processors. They range from very small to more than 1800 MIPS in lots of small upgrade increments. z9 processor upgrades are all done with microcode so there is no physical hardware installs. The idea is get what you believe you will need for the next year (or a time frame appropriate for your organization) or so, monitor its consumption, and upgrade in small steps as is necessary..
