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 paper focuses on Copy Services technology from EMC, Hitachi, and IBM within the following storage subsystem models:
- EMC DMX-4
- Hitachi USP V
- IBM DS8300
- IBM SVC
The storage software products that will be used for the different Copy Services are as follows:
- EMC TimeFinder
- Hitachi ShadowImage
- IBM FlashCopy®
While there are numerous storage subsystem vendors in the marketplace and industry, this paper has been limited to the vendors and the technologies described above.
More and more organizations will deploy (or are in the process of deploying) some form of virtualization. However, parts of an organization's systems may use earlier storage equipment. In these contexts, knowing how to migrate from physical, often direct-attached storage, to a virtual storage environment becomes valuable.
This IBM® Redbooks® publication introduces techniques to use for the migration of storage from physical to virtual environments and introduces several new features in POWER6® technology-based systems. These features include:
The chkdev command, added in Virtual I/O Server 2.1.2 FP22 to assist in identifying physical-to-virtual candidates and to ensure that device identification is consistent
Extensive use of NPIV technology for both disk and tape devices
The use of file-backed optical technology to present virtual CD media as a means of restoration
The Power E850C server (8408-44E) is the latest enhancement to the Power Systems portfolio. It offers an improved 4-socket 4U system that delivers faster IBM POWER8® processors up to 4.22 GHz, with up to 4 TB of DDR4 memory, built-in IBM PowerVM® virtualization, and capacity on demand. It also integrates cloud management to help clients deploy scalable, mission-critical business applications in virtualized, private cloud infrastructures.
Like its predecessor Power E850 server, which was launched in 2015, the new Power E850C server uses 8-core, 10-core, or 12-core POWER8 processor modules. However, the Power E850C cores are 13%-20% faster and deliver a system with up to 32 cores at 4.22 GHz, up to 40 cores at 3.95 GHz, or up to 48 cores at 3.65 GHz, and use DDR4 memory. A minimum of two processor modules must be installed in each system, with a minimum quantity of one processor module's cores activated.
Cloud computing, in its many forms (public, private, or hybrid), is quickly becoming both the delivery and consumption models for IT. However, finding the correct mix between traditional IT, private cloud, and public cloud can be a challenge. The new Power E850C server and IBM Cloud PowerVC manager can enable clients to accelerate the transformation of their IT infrastructure for cloud while providing tremendous flexibility during the transition.
IBM Cloud PowerVC Manager provides OpenStack-based cloud management to accelerate and simplify cloud deployment by providing fast and automated VM deployments, prebuilt image templates, and self-service capabilities all with an intuitive interface. PowerVC management upwardly integrates into various third-party hybrid cloud orchestration products, including IBM Cloud Orchestrator, VMware vRealize, and others. Clients can simply manage both their private cloud VMs and their public cloud VMs from a single, integrated management tool.
IBM Power Systems is designed to provide the highest levels of reliability, availability, flexibility, and performance to bring you a world-class enterprise private and hybrid cloud infrastructure. Through enterprise-class security, efficient built-in virtualization that drives industry-leading workload density, and dynamic resource allocation and management, the server consistently delivers the highest levels of service across hundreds of virtual workloads on a single system.
The Power E850C server includes the cloud management software and services to assist with clients' move to the cloud, both private and hybrid. Those additional capabilities include the following items:
Private cloud management with IBM Cloud PowerVC Manager, Cloud-based HMC Apps as a service, and Open source cloud automation and configuration tooling for AIX
Hybrid cloud support
Hybrid infrastructure management tools
Securely connect system of record workloads and data to cloud native applications
IBM Cloud Starter Pack
Flexible capacity on demand
Power to Cloud Services

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.
