THE FOUR HUNDRED - Power Systems & IBM i Insights

1. Bob More Than Just A Code Assistant, IBM i Chief Architect Will Says

   When IBM i professionals finally get their hands on Bob, the new AI-powered tool currently in development in Big Blue’s labs, they will find that it is much more than just a code assistant, IBM i chief Architect Steve Will said recently. “It has a lot of knowledge,” he said. “It knows things about IBM i.”

   While precise details about the timing of the release of Bob are slim, IBM is widely expected to release a public preview of the new AI-powered plug-in for VS Code in early 2026. The new software, which was unveiled in early October around the …

2. Stacking Up Entry IBM i-Power11 Systems Against Windows X86 Platforms

   Having spent the past several weeks going over the hardware and software costs and performance of systems in the IBM i P10 and P20 software tiers. We had an admittedly small sample, but one that we could get Big Blue’s pricing information for, which is hard to come by. This week we wanted to see how those entry P10-class and P20-class machines stack up against modern X86 servers based on Intel’s latest Xeon 6 systems running a Windows Server stack that was functionally equivalent to the IBM i stack.

   So we did a little spreadsheet work on your behalf.

   Our …

3. IBM Brings AI-Enhanced OpenShift Container Platform To Power Systems

   Given that Big Blue owns Red Hat, any Red Hat software that runs on X86 or Arm machinery should eventually make its way onto IBM’s own Power processors and their Power Systems servers. But, it takes time to do this, of course, and some Red Hat software is more important to the Power Systems based than other systems software.

   In announcement letter AD25-1628, dated November 25 when IT Junglewas, like many of you, getting ready for the Thanksgiving holiday, IBM said that it had Red Hat OpenShift Platform Plus ready to go on its Power Systems iron. The …

4. As I See It: Artificial Integrity

   I don’t remember it being taught in school. Through high school and college I cannot recall a single instance where the concept of integrity was discussed or even mentioned. Occasionally I heard words like “honest” and “honorable” applied to virtuous historical figures. But those concepts describe behavior. Integrity, on the other hand, is based on character, on a commitment to consistently practice those virtues. Integrity drives behavior but it denotes more than action; it denotes essence, a state of being whole, and ethically unabridged.

   Honor is about what you do; integrity is about who you are. Which is why a …

5. IBM i PTF Guide, Volume 27, Number 47

   We start this week with performance anxiety. Well, more like performance degradation. As you will see at this link, if you have installed IBM i 7.4 TR12 or IBM i 7.5 TR7, SQL query plans might be spending more time waiting for I/O pending faults and therefore are performing poorly. There are actually two different but related issues and two different fixes that resolve this issue.

   This week, there is also a security vulnerability. See Security Bulletin: IBM i is affected by obtaining information without proper authority [CVE-2025-36371], with more information available here. The fixes for this vulnerability, …
