Some time ago I wrote a short blog about Power and PowerVM Reference Information. Many of the PowerVM resources cover virtualization with the Virtual I/O Server (VIOS). If you are not familiar with the VIOS, I’ve shamelessly copied the following from the Knowledge Center overview information:(more…)
Here’s a great resource that you may not be aware of… the IBM Power Systems technical webinar series. These webinars were started back in 2011 and have been ongoing since. They are geared to sharing technical information related to Power, PowerVM and a virtualized power environment.(more…)
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.(more…)
Last year, IBM provided support to suspend an i partition, which I previously wrote about in “Suspend my i”.
IBM i 7.1 TR4 added Live Partition Mobility. With Live Partition Mobility, you can take an active, running IBM i partition and move it from one frame to another frame, without disruption to your applications.(more…)
An enhancement made in 7.1 was the support of Suspend/Resume, a feature of PowerVM that was already supported on AIX and Linux.
From the RFA:
PowerVM includes support for an IBM i partition to be suspended, and later resumed. Using Suspend/Resume, clients can perform long-term suspension of partitions, which frees server resources used by that partition, and later resume operation of that partition and its applications on the same server.
