Running Linux On Ibm System Z9 And Zseries Under Z Vm written by Gregory Geiselhart and has been published by IBM.Com/Redbooks this book supported file pdf, txt, epub, kindle and other format this book has been release on 2006 with Electronic books categories.

This IBM Redbooks publication discusses running Linux under z/VM on IBM System z9 and zSeries platforms. We describe enhancements available in z/VM Version 5.1. The intended audience for this book is IT administrators responsible for installing and configuring z/VM 5.1 systems running Linux guests. Using Fibre Channel Protocol (FCP), z/VM 5/1 can be installed on and operate from SCSI disks. Configured as emulated Fixed Block Architecture (FBA) disks, z/VM 5.1 can use FCP-attached disks for its system paging, spooling, directory, and minidisks. z/VM 5.1 adds new functions for Virtual Switches (VSWITCH). For increased network security, guests must have authorization before connecting to a VSWITCH. z/VM 5.1 introduces VSWITCH Layer 2 support. Operating at Layer 2, a VSWITCH delivers and receives network traffic in Ethernet frames. This provides the ability to handle non-IP protocols such as SNA, NetBIOS, and IPX. In addition, Layer 2 support reduces network latency and CPU overhead.

This IBM Redbooks publication discusses configuring and administering Linux systems running on IBM System z9 and zSeries. It is intended for system administrators and IT architects responsible for deploying Linux servers on System z9 and zSeries servers. We examine new features and enhancements of the Linux 2.6 kernel. We demonstrate Linux device configuration using sysfs and udev and discuss running Linux servers under z/VM. Networking options available for Linux on IBM System z9 and zSeries are examined in detail. Configuration of FCP-attached SCSI disks and traditional ECKD storage is demonstrated.

Z Vm And Linux On Ibm System Z The Virtualization Cookbook For Sles9 written by Michael MacIsaac and has been published by IBM Redbooks this book supported file pdf, txt, epub, kindle and other format this book has been release on 2006-04-18 with Computers categories.

This IBM IBM Redbooks publication describes how to setup your own Linux virtual servers on IBM zSeries and System z9 under z/VM . It adopts a cookbook format that provides a clearly documented set of procedures for installing and configuring z/VM in an LPAR and then installing and customizing Linux. You need a zSeries logical partition (LPAR) with associated resources, z/VM 5.2 media, and a Linux distribution. This book is based on SUSE Linux Enterprise Server 9 (SLES9) for zSeries and we address both 31-bit and 64-bit distributions. In addition, there are a few associated REXX EXECs and Linux scripts to help speed up the process. These tools are not IBM products nor formally supported. However, they are informally supported. They are available on the Web. In this book, we assume that you have a general familiarity with zSeries technology and terminology. We do not assume an in-depth understanding of z/VM and Linux. This book is written for those who want to get a quick start with z/VM and Linux on the mainframe.

This IBM® Redbooks® publication shows the power of IBM System z® virtualization and flexibility in sharing resources in a flexible production environment. In this book, we outline the planning and setup of Linux on System z to move from a development or test environment into production. As an example, we use one logical partition (LPAR) with shared CPUs with memory for a production environment and another LPAR that shares some CPUs, but also has a dedicated one for production. Running in IBM z/VM® mode allows for virtualization of servers and based on z/VM shares, can prioritize and control their resources. The size of the LPAR or z/VM resources depends on the workload and the applications that run that workload. We examine a typical web server environment, Java applications, and describe it by using a database management system, such as IBM DB2®. Network decisions are examined with regards to VSWITCH, shared Open Systems Adapter (OSA), IBM HiperSocketsTM and the HiperPAV, or FCP/SCSI attachment used with a storage area network (SAN) Volume Controller along with performance and throughput expectations. The intended audience for this IBM Redbooks publication is IT architects who are responsible for planning production environments and IT specialists who are responsible for implementation of production environments.

There are many reasons why you would want to optimize your servers through virtualization using Linux on IBM® System z®: Too many distributed physical servers with low utilization A lengthy provisioning process that delays the implementation of new applications Limitations in data center power and floor space High total cost of ownership (TCO) Difficulty allocating processing power for a dynamic environment This IBM Redbooks® publication provides a technical planning guide and example for IT organizations to migrate from their x86 environment to Linux on System z. It begins by examining the benefits of migrating workloads to Linux on System z. Here, we describe the workload centric method of information technology and then discuss the benefits of migrating workloads to Linux on System z. Next, we describe total cost of ownership analyses and we guide you in understanding how to analyze your environment before beginning a migration project. We also assist you in determining the expected consolidation ratio for a given workload type. We also describe virtualization concepts along with describing the benefits of migrating from the x86 environment to guests residing on an IBM z/VM® single system image with live guest relocation. This IBM Redbooks publication walks you through a migration approach, includes planning worksheets, as well as a chapter to assist you in analyzing your own systems. We also discuss post migration considerations such as acceptance testing of functionality and performance measurements.

This IBM® Redbooks® publication introduces the IBM System z® Personal Development Tool (zPDT), which runs on an underlying Linux system based on an Intel processor. zPDT provides a System z system on a PC capable of running current System z operating systems, including emulation of selected System z I/O devices and control units. It is intended as a development, demonstration, and learning platform; it is not designed as a production system. This book, discussing more advanced topics, is the last of three volumes. The first volume introduces zPDT and provides reference material for zPDT commands and device managers. The second volume describes the installation of zPDT (including the underlying Linux, and a particular z/OS® distribution) and basic usage patterns. The third volume discusses more advanced topics that may not interest all zPDT users. The IBM order numbers for the three volumes are SG24-7721, SG24-7722, and SG24-7723. The systems discussed in these volumes are complex, with elements of Linux (for the underlying PC machine), z/Architecture® (for the core zPDT elements), System z I/O functions (for emulated I/O devices), and z/OS (providing the System z application interface), and possibly with other System z operating systems. We assume the reader is familiar with the general concepts and terminology of System z hardware and software elements and with basic PC Linux characteristics.
