Power Systems Memory Deduplication

By: Scott Vetter,Rodrigo Ceron Ferreira de Castro,Rafael Folco,Breno Leitao,Humberto Tsubamoto,IBM Redbooks

This IBM® RedpaperTM publication introduces IBM PowerVM® Active MemoryTM Deduplication on IBM Power SystemsTM based on IBM POWER7® processor technology. Active Memory Deduplication is a virtualization technology through which memory pages with identical contents can be deduplicated in physical memory. This deduplication frees up physical memory positions so that more data can be held in memory at once. Memory deduplication is intended to work in a shared memory environment. Deduplication works with Active Memory Sharing, a technology through which multiple partitions on a system can share a pool of physical memory. Sharing this pool sometimes creates an overcommitment of this physical memory. Active Memory Deduplication increases the performance of Active Memory Sharing because the savings can be used to lower memory overcommitment levels. Reduction of memory in use can also create room to increase the memory footprint of the logical partitions (LPARs). This paper describes the advantages of Active Memory Deduplication and requirements for its use and implementation in your Power Systems. This paper also helps you set up Active Memory Deduplication on your Power System for use with IBM AIX®, IBM i, and Linux. It includes guidance for tuning parameters of Active Memory Deduplication and for troubleshooting issues. This paper targets architects and consultants who need to understand how Active Memory Deduplication technology works to design performing solutions. The paper also targets technical specialists in charge of setting up and managing Active Memory Deduplication.

IBM PowerKVM: Configuration and Use

By: Scott Vetter,Murilo Opsfelder Araújo,Breno Leitao,Stephen Lutz,José Ricardo Ziviani,IBM Redbooks

This IBM® Redpaper Redbooks® publication presents the IBM PowerKVM virtualization for scale-out Linux systems, including the new LC IBM Power SystemsTM. PowerKVM is open source server virtualization that is based on the IBM POWER8® processor technology. It includes the Linux open source technology of KVM virtualization, and it complements the performance, scalability, and security qualities of Linux. This book describes the concepts of PowerKVM and how you can deploy your virtual machines with the software stack included in the product. It helps you install and configure PowerKVM on your Power Systems server and provides guidance for managing the supported virtualization features by using the web interface and command-line interface (CLI). This information is for professionals who want to acquire a better understanding of PowerKVM virtualization technology to optimize Linux workload consolidation and use the POWER8 processor features. The intended audience also includes people in these roles: Clients Sales and marketing professionals Technical support professionals IBM Business Partners Independent software vendors Open source community IBM OpenPower partners It does not replace the latest marketing materials and configuration tools. It is intended as an additional source of information that, along with existing sources, can be used to increase your knowledge of IBM virtualization solutions. Before you start reading, you must be familiar with the general concepts of kernel-based virtual machine (KVM), Linux, and IBM Power architecture.
