Re: Sub-capacity charging - food for thought
>I am surprised nobody mentioned subcapacity CBU possibility. It was also >driven by customer demands. Excellent point. Also Capacity On Demand granularity, including single day. I'll add yet another factor: variation in how SMP-tuned our customers' workloads are. More granularity in capacity settings also means much more choice within the same engine count. There are now a lot more choices at each n-way in the 1- to 7-way ranges. Some of this had to do with an enhancement for customers running several small LPARs, to choose one example. For example, if you only look at 3-way configurations, in terms of approximate percentage capacity increases at each step you see: base, 47%, 21%, 28%, 18%, 25%, 26%, 18%, 15%, 15%, 12%, 12%, 12%, 12%, 12%, 12%, 12%, 11%, 14%, (23%) The System z9 EC 3-way full capacity is in parentheses. I've skipped some of the System z9 EC steps (except for the last one) to stick with the System z9 BC range. As you can see, even if you're a zealot about holding a 3-way configuration, these steps are almost all quite small. And that's very nice indeed, because maybe you have a workload configuration that you've precisely tuned for a 3-way system. Here's what the 3-way steps looked like on a z890 (up to a 3-way z990): same base, 77%, 91%, 25%, 57%, 22%, 74%, (20%) Not so many steps, and there are some bigger hops even though the maximum 3-way capacity is lower. - - - - - Timothy F.

Re: Sub-capacity charging - food for thought
I'm confused. Our sub capacity pricing is based on the MSU consumption, not the size of the box. Or so it appears by our monthly software bill. It has saved us some serious bucks. -Original Message- From: IBM Mainframe Discussion List [mailto:[EMAIL PROTECTED] On Behalf Of Phil Payne Sent: Friday, April 28, 2006 9:27 AM To: IBM-MAIN@BAMA.UA.EDU Subject: Sub-capacity charging - food for thought z9 BC R07 - 53 Performance levels z9 BC S07- 20 Performance levels z9 EC nnn - 24 Performance levels I think that pretty much states right out loud just how really effective sub-capacity pricing isn't. -- Phil Payne http://www.isham-research.co.uk +44 7833 654 800 -- 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
Re: Sub-capacity charging - food for thought
I am surprised nobody mentioned subcapacity CBU possibility. It was also driven by customer demands.

As mentioned upthread, many customers wanted additional hardware granularity, especially on the System z9 EC. Also, while it would be nice if all software were available on a subcapacity basis (e.g. IBM's WLC), some customers have old contracts and/or vendors that don't yet provide subcapacity pricing. Fortunately more and more vendors seem to be adopting subcapacity pricing in one form or another. I have worked with at least one customer that now has all their software priced at subcapacity. Indeed they are less concerned about these fine capacity increments, and they run some of their Linux work on spare CP capacity. They may have other reasons to get System z9 (e.g. zIIP), but granularity is not much of a factor for them. Your mileage may vary. - - - - - Timothy F.

We've actually gotten a couple of good deals on sub-capacity licensing. Agreed. I would complement, that sub-capacity licensing gives you good granularity on software prices, while performance levels address granularity of hardware prices. If you have 2 CPs at 99% and you want to grow-up by approx. 10%, then your software fees (ok, only variable part of it) will grow up by 10%, but in the past you had to buy WHOLE CP. Not 2x10% of CP. Whole. With BC machine you can buy next performance level. That's OK for me. I remain many predictions and capacity plans, very precisely created, but the answer was quite roughly: you have to buy another CP. -- Radoslaw Skorupka Lodz, Poland -- 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
