Crazy Idea Number 615: Variable Priced Power Systems Partitions

April 5, 2021 Timothy Prickett Morgan

When you stare down the blank page as much as I have in my career, you learn to not be afraid of that blank page. If you look at it long enough – usually for only a few minutes – ideas flip into existence like quantum particles spinning their curlicues. Most of them are silly, some are utterly useless, but eventually you get one that is worth following to see where it might go.

So it is with an idea that popped into my head, which was a daydream about IBM creating variable priced partitions on the Power Systems machines. …

Max Thread Room

September 28, 2020 Timothy Prickett Morgan

For a lot of organizations that buy servers and create systems out of them, the overall throughput of each single machine is the most important performance metric they care about. But for a lot of IBM i shops and indeed even System z mainframe shops, the performance of a single core is the most important metric because most IBM i customers do not have very many cores at all. Some have only one, others have two, three, or four, and most do not have more than that although there are some very large Power Systems running IBM i. But that …

IBM Revamps Entry Power Servers With Expanded I/O, Utility Pricing

July 14, 2020 Timothy Prickett Morgan

Believe it or not, but it has been two and a half years since the first Power9 server shipped and it has been more than two years since the entry Power Systems machines – that would be the Power S914, the Power S922, and the Power S924 machines, code-named “ZZ” after the country-rock-blues band from Houston – were first announced. And today, these machines are getting an I/O makeover.

And specially for IBM i shops, IBM is rolling out a single-core version of the Power S922 that will offer better bang for the buck as well as lower acquisition cost …

New System z15 Mainframe Takes The Heat Off Power Systems

September 16, 2019 Timothy Prickett Morgan

I don’t know if many of you work this way, but sometimes I have to say things out loud and follow that train of thought before I decide it is a good, bad, or neutral idea – or any of the different gradations in there and beyond these from absolutely wonderful on one end to impossible or worse yet impossible on the other end. It is a kind of branch prediction, and like modern processors for the past two decades, it is subject to Meltdown speculative execution vulnerabilities.

(That right there was a nerd joke. I think. Maybe. . …

Melding System Monitoring And Capacity Planning

April 24, 2019 Timothy Prickett Morgan

Installing a modern system to run enterprise applications is a pretty tough task, but the job is not done once the iron is in and the databases and applications are up and running. Sophisticated organizations, whether they are large or small, do sophisticated application and system monitoring to keep an eye on how things are running, they have job schedulers that synchronize work to optimize for performance as well as drive up system utilization, and they use all of the information gathered to better plan for the kinds of systems they will need in the future.

There are many …

For Entry IBM Shops, Power9 Is About Performance And Security

December 10, 2018 Timothy Prickett Morgan

Buying new systems costs money, often a lot of money relative to the size of the overall IT budget and the revenue and profit streams of the companies for which they work and, in essence, actually embody what that company really is. So in a sense, systems are always worth the money if they are actually letting people do their work properly.

That said, there is always an argument to be made for doing an upgrade – often actually a migration because the system itself cannot easily or economically be upgraded – and another set of arguments for waiting a …

Goosing Big Iron Power Systems With Power9 Migrations

December 3, 2018 Timothy Prickett Morgan

The Power9-based servers from IBM’s Cognitive Systems division have been rolling out over the course of the past year, and the big iron has been in the field only since the late summer but has perhaps had the largest impact on the revenue and profit stream for the Power Systems line, excepting maybe the installation of the “Summit” and “Sierra” supercomputers for the U.S. Department of Energy’s Oak Ridge National Laboratory and Lawrence Livermore Laboratory.

As has been the case since the AS/400 line debuted in 1988 and even with the combination of the System/36 (low-end and midrange) and System/38 …

Bang For The Buck On Power9 Entry Hardware

March 19, 2018 Timothy Prickett Morgan

When it comes right down to it, there are three things that drive a server upgrade or new system purchase among IBM midrange shops: They have an aging system that has to be replaced, workloads are expanding and driving new capacity, or new workloads are being added to the system. In many cases, the situation involves two or even all three of these factors. But what gets the deal done is the value that the new system brings above and beyond satisfying those needs. You have to get a good deal so everyone looks like a hero.

The good news …

The Performance Impact Of Spectre And Meltdown

March 12, 2018 Timothy Prickett Morgan

We have been waiting to see what impact on performance the Spectre and Meltdown speculative execution patches, which plug some security vulnerability holes that search engine giant Google discovered last summer and made public in early January, would have on Power Systems iron running the IBM i operating system.

Now that Big Blue has published the first edition of the Power Systems Performance Report that includes the new “ZZ” Power 9-based systems, we not only get a sense of the relative performance of the “Nimbus” Power9 chip for entry servers. We also can figure out the performance impact of the …

IBM Preps Power9 “ZZ” Systems For Imminent Launch

February 12, 2018 Timothy Prickett Morgan

In last Monday’s issue of The Four Hundred, I told you that the market was getting restless for the rollout of the mainstream servers based on the Power9 processor, and Jenny Thomas, our publisher, commented on our @ITJungleNews Twitter feed that it was also me that was getting restless. Indeed, I am. My iron level is getting low, I suppose.

Well, the good news for both you and me is that the “ZZ” variants of the Power Systems platforms, which we talked about last week based on the chatter we have been hearing, are coming sooner rather than later. …
