IBM PowerHA SystemMirror for i was first introduced in 6.1 and has received continual updates and new functionality since then. As PowerHA has grown, new features such as the recent HyperSwap technology continue to bring even more high availability and disaster recovery options to meet the ever-changing and diverse needs of businesses around the world.
PowerHA now offers solutions that fit customers both at the largest end of the spectrum with the largest Power Systems and latest storage area network (SAN) technologies as well as those with just one or two cores on internal storage.

One of the challenges with IBM i on IBM Power Systems is simply knowing everything you need to know. It’s what you don’t know that can get you into trouble! This blog generally focuses on IBM i information.

I’ve heard many clients state that PowerHA is too complex or expensive for the small-to-medium IBM i environments, so this week, Steve Finnes is here on ‘i Can’ to answer a few questions.

I like birthdays, even as the numbers get larger. I’ll admit that I like to get birthday presents; I like to give them too. This week marks the 4th year of the “i Can” blog, so this week’s blog is a gift of reading material.
The reference material in this blog is a bit dated, but I left it in place as some of these links are still useful. I will write a 2020 version at some point.

I want to tell you about a recently announced enhancement to IBM i 7.1 that allows you to natively attach entry-level external storage even to a Power Systems Express Model 710 or 720. Some of the supported configurations do not require a switch. This gives you a low-cost entry point into an external storage configuration that is a building block for some of the newer Power Systems and IBM i technologies, and gives an option for adding additional storage to the Power Systems Express systems that cannot attach an additional I/O drawer.
