It’s Getting Cloud-i In Here

June 10, 2019 Alex Woodie

For many years, the only cloud option that IBM i customers had available to them were private clouds delivered by managed service providers (MSPs) or IBM business partners. But the IBM i community is now on the cusp of gaining not one but three public cloud options, delivered by Skytap, Google, and IBM itself – and more IBM i public clouds could be on the way.

It’s no secret that IBM has been seeking to place IBM i servers in the big three public clouds managed by Amazon Web Services, Microsoft Azure, and Google Cloud. And in …

Retranslation Could Boost Performance

May 13, 2019 Timothy Prickett Morgan

There are so many kinds of genius embedded into the IBM midrange line that it is hard to know where to begin when discussing all of these interconnected ideas and layers. But perhaps the simplest way to encapsulate them all is that the System/38 and AS/400 minicomputers and their follow-ons sought to abstract away and mask some of the more complex aspects of a modern system so that programmers could focus on business logic and system administrators could focus at a much higher level, too.

One of the key differentiators of these IBM midrange platforms, and one of the hallmarks …

Enterprises Spend On Systems, Hyperscalers Tap The Brakes

March 11, 2019 Timothy Prickett Morgan

For many enterprises, the current generations of processors that come from IBM, Intel, AMD, and the Arm collective are plenty good enough – and available at reasonable price/performance relative to each other and to their predecessors – that the end of 2018 was a perfectly reasonable time to buy what is on the truck. But hyperscalers and public cloud builders, who live and die by the total cost of ownership of their systems as gauged by raw compute power, space required, and power consumed, have to take a longer view. So with new processors coming from Intel and AMD on …

The Herculean Task Of Applying Spectre/Meltdown Patches

October 1, 2018 Timothy Prickett Morgan

The Spectre and Meltdown speculative execution vulnerabilities are, as our resident chief technology officer and author of the weekly IBM i PTF Guide, Doug Bidwell, is fond of saying, the gift that just keeps on giving.

We had the shock of finding out in January that there were vulnerabilities in all processor architectures that use speculative execution in their instruction chewing engines – that means all existing processors, by the way. There are none that do not use this very useful architectural feature. And then we had the wait to see what the industry would do to patch these …

Contain Your IBM i Enthusiasm

May 1, 2017 Timothy Prickett Morgan

In the IT business, what is old is often new again. And so it is with the software containers that are taking certain datacenters by storm these days, and the virtual machines and hypervisors that run them that predate them as a volume product on X86 servers by a decade.

Let’s have some fun with history.

Virtual machines were invented for IBM mainframes in the VM operating system way back in the dawn of time, well, 1972 with the launch of Virtual Machine Facility/370, which ran a lightweight operating system called the Conversational Monitoring system and as it matured could …
