PowerVM Processor Virtualization 101 Part 2

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.”

PowerVM Processor Virtualization 101

This is the first installment in a two-part blog series to provide basic introduction to the PowerVM processor virtualization terminology and acronyms. The first part will be heavy on terms without much explanation; the second part will be just the opposite. 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.” Let’s get started…

IBM Power Virtualization Performance (PowerVP)

Do you have an IBM POWER7 or POWER8 server with virtualized workloads? If so, you probably have a need to monitor and manage the performance of these virtual workloads. IBM provides many performance tools at the operating system level that do a great job monitoring LPAR performance, but in order to see what is happening on the system level and how each partition is working in relation to the other partitions, you had to put together a jigsaw puzzle of information gathered from each partition. What is missing is a single view and collection of performance information at the system level. PowerVP fills this gap by providing a systemwide view of all of the LPARs on your POWER system with utilization information for the partitions. It also provides utilization information for the physical hardware that can be used to help you understand and manage the partitions and workloads on your system.

A Low-Cost External Storage Configuration With IBM i

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.
