Earlier this month I wrote about PowerVM Live Partition Mobility and Simplified Remote Restart, and I hope you want to get your I/T environment LPM and SRR capable to exploit these features.(more…)
This article explains how to leverage two IBM Power Server features to reduce downtime for maintenance and migrations and unplanned outages. Let’s start by reviewing some important PowerVM features that give customers more flexibility to keep their LPARs up and running for a variety of data center changes.(more…)
This is the second installment in a two-part blog series to provide basic introduction to the PowerVM processor virtualization terminology and acronyms. The first part was heavy on terminology. This part will tie the terminology together and provide you with a better understanding of the trade-offs involved with PowerVM LPAR configuration as it pertains to processor virtualization. The IBM Redbooks publication, “IBM PowerVM Virtualization Introduction and Configuration” provides much greater detail. For an in-depth treatment of this material from an IBM i perspective, see “Under the Hood: POWER7 Logical Partitions.”(more…)
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…)
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…)
