This IBM® RedpaperTM publication introduces PowerVMTM Active MemoryTM Sharing on IBM Power SystemsTM based on POWER6® and later processor technology. Active Memory Sharing is a virtualization technology that allows multiple partitions to share a pool of physical memory. This is designed to increase system memory utilization, thereby enabling you to realize a cost benefit by reducing the amount of physical memory required. The paper provides an overview of Active Memory Sharing, and then demonstrates, in detail, how the technology works and in what scenarios it can be used. It also contains chapters that describe how to configure, manage and migrate to Active Memory Sharing based on hands-on examples. The paper is targeted to both architects and consultants who need to understand how the technology works to design solutions, and to technical specialists in charge of setting up and managing Active Memory Sharing environments.

IBM® PowerVM® virtualization technology is a combination of hardware and software that supports and manages the virtual environments on POWER5-, POWER5+, IBM POWER6®, and IBM POWER7®-based systems. PowerVM is available on IBM Power SystemsTM, and IBM BladeCenter® servers as optional Editions, and is supported by the IBM AIX®, IBM i, and Linux operating systems. You can use this set of comprehensive systems technologies and services to aggregate and manage resources by using a consolidated, logical view. Deploying PowerVM virtualization and IBM Power Systems offers you the following benefits: Lower energy costs through server consolidation Reduced cost of your existing infrastructure Better management of the growth, complexity, and risk of your infrastructure This IBM Redbooks® publication is an extension of IBM PowerVM Virtualization Introduction and Configuration, SG24-7940. It provides an organized view of best practices for managing and monitoring your PowerVM environment concerning virtualized resources managed by the Virtual I/O Server.

The Virtual I/O Server (VIOS) is part of the IBM PowerVM® feature on IBM® Power SystemsTM and part of the IBM POWER® HypervisorTM. The VIOS is also supported on IBM BladeCenter®. The server is a single-function appliance that is in the logical partition (LPAR) of the Power Systems server. The VIOS facilitates the sharing of physical I/O resources between client partitions (IBM AIX®, IBM i, and Linux) within the server. The Virtual I/O Server provides a virtual SCSI target, N_Port ID Virtualization (NPIV) target, and Shared Ethernet Adapter (SEA) virtual I/O function to client LPARs. The Virtual I/O Server has the capability of a hardware management function, the Integrated Virtualization Manager (IVM). IVM is a simplified hardware management solution that inherits most of the Hardware Management Console (HMC) features. The console manages a single server, avoiding the need of a dedicated personal computer. This device is designed to provide a solution that enables the administrator to reduce system setup time and to make hardware management easier, at a lower cost. IVM provides a management model for a single system. Although it does not offer all of the HMC capabilities, it enables the exploitation of PowerVM technology. IVM targets the small and medium systems that are best suited for this product. IVM provides the following functions: - Shared Storage Pool - IBM Active MemoryTM Sharing (AMS) - Live Partition Mobility (LPM) - Task manager monitor for long-running tasks - Security additions such as viosecure and firewall, and other improvements There are many environments where there is the need for small partitioned systems, either for test reasons or for specific requirements, for which the HMC solution is not ideal. A sample situation is where there are small partitioned systems that cannot share a common HMC because they are in multiple locations. In these cases, IVM works. Using IVM, companies can more cost-effectively consolidate multiple partitions onto a single server. With its intuitive, browser-based interface, the IVM is easy to use and significantly reduces the time and effort that is required to manage virtual devices and partitions. This IBM RedpaperTM publication provides an introduction to IVM by describing its architecture and showing how to install and configure a partitioned server by using its capabilities. This document is intended for IT personnel who have a complete understanding of partitioning before reading this document.

This IBM® RedpaperTM publication describes the adapter-based virtualization capabilities that are being deployed in high-end IBM POWER7+TM processor-based servers. Peripheral Component Interconnect Express (PCIe) single root I/O virtualization (SR-IOV) is a virtualization technology on IBM Power Systems servers. SR-IOV allows multiple logical partitions (LPARs) to share a PCIe adapter with little or no run time involvement of a hypervisor or other virtualization intermediary. SR-IOV does not replace the existing virtualization capabilities that are offered as part of the IBM PowerVM® offerings. Rather, SR-IOV compliments them with additional capabilities. This paper describes many aspects of the SR-IOV technology, including: A comparison of SR-IOV with standard virtualization technology Overall benefits of SR-IOV Architectural overview of SR-IOV Planning requirements SR-IOV deployment models that use standard I/O virtualization Configuring the adapter for dedicated or shared modes Tips for maintaining and troubleshooting your system Scenarios for configuring your system This paper is directed to clients, IBM Business Partners, and system administrators who are involved with planning, deploying, configuring, and maintaining key virtualization technologies.
