Entry Server Bang For The Buck, IBM i Versus Red Hat Linux

November 11, 2019 Timothy Prickett Morgan

In last week’s issue, we did a competitive analysis of the entry, single-socket Power S914 machines running IBM i against Dell PowerEdge servers using various Intel Xeon processors as well as an AMD Epyc chip running a Windows Server and SQL Server stack from Microsoft. This week, and particularly in the wake of IBM’s recent acquisition of Red Hat, we are looking at how entry IBM i platforms rate in terms of cost and performance against X86 machines running a Linux stack and an appropriate open source relational database that has enterprise support.

Just as a recap from last week’s …

After Seven Quarters Of Growth, Power Systems Declines

October 21, 2019 Timothy Prickett Morgan

The tough compares have hit home on IBM’s Power Systems business, but the good news is that this has happened after seven consecutive quarters of growth for the Power-based server business that Big Blue owns lock, stock, and barrel. Even with this decline, which was quite steep because of the triple whammy of tough compares (more on that in a moment), there is still a healthy underlying Power Systems business that is much better off than the last time it was hit by similar declines.

Let’s take a look at the numbers for IBM’s Power Systems division and then work …

Monoliths, Microservices, and IBM i Modernization: Part 2

October 14, 2019 Alex Woodie

Microservices are the future, right? After reading part one of this series, you can be excused for thinking that. Breaking up applications into smaller components brings clear benefits to both the development and operations staff, and clearly is an architectural approach that has a lot of momentum. But it turns out there might be practical limits to how far the microservices approach can take us.

“Loosely coupled, yet tightly integrated.” That phrase became something of a running joke at an Infor conference attended by this reporter several years ago. The company at the time was betting heavily on its ION …

Systems Software Stack Tweaked For Power Systems

October 14, 2019 Timothy Prickett Morgan

As part of the October Power Systems announcements, IBM has made some minor tweaks to the systems software stack that runs underneath IBM i, AIX, and Linux on its Power-based systems.

In announcement letter 219-451, IBM reveals enhancements to its PowerVM server virtualization hypervisor, the PowerVC implementation of the OpenStack cloud controller (which presumably has a pretty short life now that IBM owns Red Hat), and its Virtual HMC (vHMC) hardware management console for Power iron.

The details are a bit thin, but IBM has made improvements with PowerVM V3.1.1 so Live Partition Mobility live migration of logical partitions …

Let’s Try Converged Power Infrastructure One More Time

April 8, 2019 Timothy Prickett Morgan

Do you remember the Flex System modular servers launched seven years ago this month? These were the innovative machines that Big Blue sold off to Lenovo about two and a half years after they were launched and they were ramping? Do you remember the PurePower follow-ons to these that came out in May 2015? Or did we all just imagine that happened?

These modular machines, which were somewhere halfway between a rack server and a blade server, were put into preconfigured stacks and as the PureFlex system had cloud automation software to create a private cloud and then had …

Traditional IT Spending Bests Cloud Infrastructure, For Now

April 1, 2019 Timothy Prickett Morgan

Drawing the line between what is cloudy and what is not at this point in the history of the information technology business is not a trivial thing. But that’s why the analysts at IDC, Gartner, Forrester, and others get paid the big bucks to dice and slice the market so we can get a better of what is going on.

To hear the big public cloud providers talk, you would think that everything that companies buy to install on premises or rent from their bit barns is cloudy – which means that it is virtualized, available with metered pricing to …

IBM Winds Down PowerVM V2, Nudges Customers To PowerVM V3

November 12, 2018 Timothy Prickett Morgan

It may not occur to you, but the PowerVM server virtualization hypervisor that Big Blue created for Power Systems servers has a version just like every other piece of software in the world, and like all software, it ages and eventually it is retired from the field in lieu of more modern code.

In announcement letter 918-129, IBM let it be known that PowerVM V2, of which there were three releases, will be withdrawn from marketing on February 19, 2019 and will have its support withdrawn on September 30, 2020. That may seem like a long time away from …

Kubernetes Container Control Comes To Power Systems

October 29, 2018 Timothy Prickett Morgan

The moment that Google created a clone of parts of its internal Borg cluster and container management system and open sourced it as the Kubernetes project, the jig was pretty much up.

Google had done a lot of the fundamental work to bring containers to the Linux platform starting way back in 2005, and had shared its techniques with the open source community, leading directly to the Docker container format and the engine that runs it atop the Linux kernel. While Docker, the company, got a jump start with its Docker Swarm container orchestrator and then its fuller Docker Enterprise …
