Getting Hyperconverged On Power Systems

July 17, 2017 Timothy Prickett Morgan

A few weeks ago, when pondering the possibilities of how Big Blue might reimagine and reinvigorate the IBM i platform, we outlined how this might be done – and how it might apply to a much broader customer base after it was done – in an article called The Cognitive Systems/500 2018 Edition. We forgot one of the possible components of a modern, integrated system and, amusingly, IBM has just announced support for it.

The bit of the software stack we forgot to mention was what is called hyperconverged infrastructure, or HCI for short, and this server-storage halfblood has …

Of Course i’s Not The AS/400

July 17, 2017 Alex Woodie

The AS/400 was a great computer. No doubt about that. In the pantheon of business machines, you’d be hard-pressed to find anything that remotely compares to IBM’s long-lived midrange champion. But today’s IBM i on Power Systems platform has evolved far beyond the AS/400, and midrange professionals who cling to the old words and ways are doing us all a disservice. Are you one of them?

Chances are, you’re not. If you’re reading this article, you’re likely one of the “engaged” midrange professionals who takes an active interest in news, works to improve your skills, and embraces newer technologies available …

Guru: Conditional SQL Unions

July 17, 2017 Ted Holt

SQL unions combine two or more result sets into one. That’s what they were designed to do. But unions also provide a way to choose between alternate result sets, i.e. to enable or disable SELECT statements at run time. I have used this feature to advantage on numerous occasions. Here’s how it’s done.

First consider the nature of unions. Each result set of a union can return data or no data, depending on the criteria in the WHERE and HAVING clauses. If a SELECT retrieves no data, the system appends an empty set to the union result. The way to …

IBM i Security Expert Interprets PCI and Multi-Factor Authentication

July 17, 2017 Dan Burger

With data security written boldly at the top of many organizations’ priority lists, the Payment Card Industry Data Security Standard (PCI DSS) is viewed as a top line defense against data breaches. Whether a company handles credit cards and is required to implement mandated security measures or uses the PCI standard as a best practices model, IT security gurus pay attention to the PCI DSS.

We are well beyond the realization that organizations need to be secure. The emphasis has clearly shifted to how organizations become secure. How to build and maintain a secure network, protect data and regularly monitor …

Mixed Results For IT Spending Forecasts

July 17, 2017 Timothy Prickett Morgan

We have made it through the first half of 2017, and now is a good time to take a pause and count the money that the IT vendors of the world have amassed from the hardware, software, and services they provide to the datacenters of the world. And so, IDC and Gartner have done just that even ahead of the reporting of financial results for the second quarter. The results from these two firms generally agree, and they show that, as always, different parts of the business are growing even as other parts slow or even shrink.

One big reason …
