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 …

Thoroughly Modern: Why You Need An IT Strategy And Roadmap

July 14, 2020 Timothy Prickett Morgan

What makes a modernization project successful? Is it the right software and tools? Having the right people on the job? Completing the project on time and on budget? Some might argue that all of the above contribute to the overall success of these initiatives. But the experts at Fresche will tell you that building a comprehensive strategy and roadmap is the most important part. It’s the secret sauce that ensures that the project provides business value and that requirements are mapped out before you start. After all, failing to plan is planning to fail.

Businesses today are facing increasing pressure …

Guru: The Case for Mixed-Case Procedure Names

July 14, 2020 Paul Tuohy

Using mixed case makes source code easier to read and easier to debug. I programmed in all upper case for many, many years, so I don’t recoil in horror when I see something in all uppercase. However, it’s a bit more difficult for developers who aren’t quite as long in the tooth as I am. To them, all uppercase is pretty abhorrent and bad (and I don’t mean bad as in good).

There is a potential case issue with subprocedure names: there are at least three places on the system where the system shows subprocedure names in uppercase, regardless of …

The Path Truly Opens To Alternate Power CPUs, But Is It Enough?

July 14, 2020 Timothy Prickett Morgan

If you have a few tens of millions of dollars to spare and you want to set up a foundry partnership with either Globalfoundries for 14 nanometer chip making technologies or with Samsung for 7 nanometer technologies and then create your own Power processor, things just got a little bit easier. Big Blue has open sourced one of its Power cores through the OpenPower foundation and now anybody and everybody can grab it and design a new central processing unit around that core.

Don’t get too excited, but get a little excited. Let me explain.

We still believe in the …

IBM i PTF Guide, Volume 22, Number 27

July 14, 2020 Doug Bidwell

Welcome to the second half of 2020 after a brief holiday hiatus from The Four Hundred and therefore the IBM i PTF Guide.

There is another new HIPER for the Virtual I/O Server, or VIOS, which again we know all of you IBM i shops love dearly. The HIPER is IJ25390, and it is for slow TCP performance with the Virtual Ethernet adapter and large send. Here is some more on that LSO – short for large send offload – and specifically a link that explains it better than we did two weeks ago, plus another link to a …
