Inside The IBM “Denali” Power E1080 System

November 8, 2021 Timothy Prickett Morgan

With Big Blue not really shipping its Power10-based big, bad “Denali” Power E1080 system in full volume and with full configurations until December, we knew we would have some time to dig down into the architecture of the Denali systems. And with other things out of the way, which also needed to be covered, including our initial coverage on the Power E1080 machine on September 8 and some follow-on stories, we are now eagerly taking the lid off the Denali machine and taking a hard look at it for you.

Seriously. Here is the machine with the lid off of …

Thoroughly Modern: Infrastructure Challenges And Easing Into The Cloud

November 8, 2021 Marcel Sarrasin

There is an old saying, purportedly a Chinese curse but never proven to be anything but a saying by English diplomats who interfaced with the Middle Kingdom: “May you live in interesting times.” There is an equally mistaken etymology that the word for “crisis” in Chinese is comprised of two Mandarin words for “danger” and “opportunity.”

Even though people misunderstand the source of these sayings, and the latter one is just simply not true at all, it is still the case that there has never been a more interesting time in the information technology sector in general and …

Guru: Abstract Data Types and RPG

November 8, 2021 Ted Holt

An abstract data type (ADT) is a type of data and a set of operations defined over that type of data. Using ADTs allows a programmer to work with data in terms of functionality rather than physical representation. The ADT is the basis of object-oriented programming. Does that mean that abstract data types don’t apply to procedural languages like RPG? Not at all. Quite the contrary.

Before I show you how you can use abstract data types in RPG-based applications, let me further illustrate abstract data types with another, non-OO object — the user profile. The user profile is a …

November 8, 2021 Alex Woodie

IBM i shops that are concerned about security – and really, who isn’t concerned about their security these days? – may be interested in receiving a free security check from the experts at IBM Systems Lab Services.

The IBM i Security Quick Check, as the free offering is called, was introduced by IBM in October as a way to help IBM i shops pinpoint the areas where their servers are susceptible to external attacks, insider threats, and malware.

The security check will let organizations know where the security vulnerabilities exist in their IBM i configurations, according to a blog post …

Gartner Revises IT Spending Forecasts Upward For 2021 And 2022

November 8, 2021 Timothy Prickett Morgan

With a market as large as the information technology racket, small changes rack up to tens of billions of dollars up or down in global spending. Any increase is generally seen as good news because so many of the individual IT budgets are gauged against the global average. So, in a sense, it just got a little bit easier for you to argue that your own IT department should be spending more dough on IT because the prognosticators at Gartner have just raised their forecast for IT spending in 2022.

It’s not much of an increase, mind you. So don’t …
