THE FOUR HUNDRED - Power Systems & IBM i Insights

1. Stacking Up Power11 Entry Server Performance To Older Iron

   Here we are heading into the fall and if you have budget set aside for a new system or an upgrade, now is the time to start thinking about spending it. For customers buying mainstream P10-class and P20-class systems, the Power11 machines that have been out for a few months now and are the machines you will need to consider. And if you have older Power8 or Power9 iron, you might even be considering an upgrade to a Power10.

   With all of this in mind, we have put together the mother of all performance tables to compare the current and …

2. Big Blue Boosts IBM i Support In Instana, Adds Tracing

   IBM i shops that need more insight into how their hardware and software is running may want to consider IBM’s Instana software. IBM has been investing in the observability tool, which was recently updated to support traces on IBM i systems. That’s one of several upgrades IBM has made to Instana to help its IBM i customers.

   IBM acquired Instana back in November 2020 to bolster its presence in the nascent observability arena, particularly as it related to monitoring cloud-native environments (i.e., those using Kubernetes and microservices). Big Blue had just spent $34 billion to buy Red Hat and its …

3. It Is Time To Tell Us What You Are Thinking And Doing

   It is the beginning of fall, or autumn if you are in Europe, and you know what that means. No, it is not the deciduous woods turning to the colors of fire. Not it is not football (or soccer for that matter), or harvest time. But it is the time when Fortra opens up its annual IBM i Marketplace Survey, which has been running for more than a decade now.

   The annual survey, which is in its 13^th year, opened on September 15. You can give back to the IBM i community and help nudge IBM and ISVs in …

5. The GenAI Boom Is Only Slightly Louder Than The Dot Com Boom

   In most markets, revenues and hopefully profits go from exponential growth to log growth to linear growth in the fullness of time. We are living in the exponential phase of AI, and for GenAI in particular, where the x in y=a^x is a pretty big number and the resulting revenue growth looks like the proverbial hockey stick.

   The numbers can be a bit surreal, as they seemed back in the Dot Com boom, where we turned on mainstream stores into warehouses with delivery services. With AI, we are turning the digital data of our lives into data warehouses and …
