Does Db2 Mirror Kill The Market for Third Party HA?

May 6, 2019 Alex Woodie

IBM launched Db2 Mirror for i two weeks ago to great acclaim, as the clustering technology puts IBM i on par with how most other major systems provide continuous availability. But will Db2 Mirror destroy the platform’s heritage of high availability solutions? IT Jungle asked IBM and the biggest providers of logical replication solutions, and the answer is no. Here’s why.

The first thing to understand about Db2 Mirror is that, at heart, it’s a database clustering technology. IBM figured out a way to make a single instance of Db2 for i run on two separate systems, in an active-active …

Drilling Down Into Db2 Mirror for IBM i

May 6, 2019 Timothy Prickett Morgan

We did our initial coverage of the new Db2 Mirror for the IBM i operating system’s integrated database two weeks ago, and now it is time to dig in a little deeper. Elsewhere in this week’s issue of The Four Hundred, we have gotten feedback from the suppliers of high availability clustering and disaster recovery software for the IBM i platform as to how Db2 Mirror compete with as well as complements their wares. And in this story, we will be digging a little deeper into Db2 Mirror itself.

As we explained, Db2 Mirror creates an active-active database …

April 24, 2019 Timothy Prickett Morgan

(Sponsored Content) Installing a modern system to run enterprise applications is a pretty tough task, but the job is not done once the iron is in and the databases and applications are up and running. Sophisticated organizations, whether they are large or small, do sophisticated application and system monitoring to keep an eye on how things are running, they have job schedulers that synchronize work to optimize for performance as well as drive up system utilization, and they use all of the information gathered to better plan for the kinds of systems they will need in the future …

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 …

IBM Bolsters Disaster Recovery With GDR For IBM i

May 3, 2017 Alex Woodie

IBM next month plans to start selling a new disaster recovery product to IBM i shops. Called Geographically Dispersed Resiliency, or GDR, the new offering is designed to give companies an easy and affordable way to recover production IBM i LPARs on remote machines. IBM’s resiliency guru Steve Finnes gives IT Jungle the lowdown on the new tech.

GDR provides DR protection by essentially taking a production logical partition (LPAR), also called a virtual machine (VM), from one IBM i server and restarting it on another IBM i server. The VMs involved in a GDR switch must be stored on …
