  • Linux on POWER
    http://ibmsystemsmag.com/CMSTemplates/IBMSystemsMag/Print.aspx?... close window Print May 2016 | by Jaqui Lynch IBM is serious about Linux on POWER. Linux now runs on every POWER8 server, with specialized offerings for Linux. These include the new LC (Linux only, PowerKVM only) servers, the L model (Linux only) servers, Linux IFLs, EasyScale for MSP offerings, and SAP Hana on POWER. Additionally, significant work has been done to encourage ISVs to increase their offerings on Linux on POWER, resulting in a flourishing ecosystem that wasn’t available on POWER five years ago. Power systems are designed for big data and optimized for performance and scalability. They provide great I/O and memory bandwidth with significant reliability and other availability features not available anywhere else except the mainframe. With full support for various levels of RHEL (Redhat Enterprise Linux), SLES (SuSE Linux Enterprise Server) and Ubuntu, it’s a great time to consider migrating to Linux on Power. Here are some decisions to make: 1. Do you want to run Linux alongside other workloads like AIX or IBM i 2. Do you want to run a Linux only server 3. Do you want to use and HMC or virtual HMC to control the server (won’t work with PowerKVM) 4. Do you want to use PowerKVM or PowerVM for virtualization 5. Do you have some dark cores and memory that you would like to run Linux on at a reduced rate 6. Do you have x86 workload running on Linux that you would like to migrate 7. Do you want to reduce costs for IBM software (PVU based licensing) Reducing costs Software can be expensive, especially middleware.

However, the reader should have a basic understanding of I BM data processing. VM/370 (Virtual Machine Facility/370) is a system control program (SCP) that tailors the resources and capabilities of a single System/370 computer to provide concurrent users their one unique (virtual) machine. VM/370 consists of a Control Program (CP), which manages the real computer, a Conversational Monitor System (CMS), which is a general-purpose conversational time-sharing system that executes in a virtual machine, a Remote Spooling Communications Subsystem (RSCS), which spools files to and from geographically remote locations, and a Interactive Problem Control System (I PCS), which provides problem analysis and management faci I ities. The first section of the publication is an introduction; it describes what VM/370 can do. The second, third, fourth, and fifth sections describe the Control Program, Conversational Monitor System, Remote Spooling Communications Subsystem, and Interactive Problem Control System respectively. The appendixes include information about VM/370 publication-to-audience relationship and VM/370-related publications for CMS users. , This publication is a prerequisite for the VM/370 system library. --...- --- ---.-- ------- ------ --..- --------- -~-y- Page of GC20-1800-9 As Updated Aug 1, 1979 by TNL GN25-0U89 ~b Edition (Karch 1919) This edition (GC20-1800-~ together with Technical Newsletter GN25-0489. dated August 1, 1919, applies to Release 6 PLC 4 (Program Level Change) of IBM Virtual Machine Facility/310 and to all subsequent releases until otherwise indicated in new editions or Technical Newsletters.

  • The Server Virtualization Landscape, Circa 2007
    ghaff@ illuminata.com Copyright © 2007 Illuminata, Inc. single user license Gordon R Haff Illuminata, Inc. TM The Server Virtualization Bazaar, Circa 2007 Inspired by both industry hype and legitimate customer excitement, many Research Note companies seem to have taken to using the “virtualization” moniker more as the hip phrase of the moment than as something that’s supposed to convey actual meaning. Think of it as “eCommerce” or “Internet-enabled” for the Noughts. The din is loud. It doesn’t help matters that virtualization, in the broad sense of “remapping physical resources to more useful logical ones,” spans a huge swath of Gordon Haff technologies—including some that are so baked-in that most people don’t even 27 July 2007 think of them as virtualization any longer. Personally licensed to Gordon R Haff of Illuminata, Inc. for your personal education and individual work functions. Providing its contents to external parties, including by quotation, violates our copyright and is expressly forbidden. However, one particular group of approaches is capturing an outsized share of the limelight today. That would, of course, be what’s commonly referred to as “server virtualization.” Although server virtualization is in the minds of many inextricably tied to the name of one company—VMware—there are many companies in this space. Their offerings include not only products that let multiple virtual machines (VMs) coexist on a single physical server, but also related approaches such as operating system (OS) virtualization or containers. In the pages that follow, I offer a guide to today’s server virtualization bazaar— which at first glance can perhaps seem just a dreadfully confusing jumble.

The commoditization of the (binary translation) that enabled the execution of privileged x86 platform and its rapidly growing hardware capabilities have (OS) instructions from virtual machines on x86 systems [16]. led to recent exponential growth in the use of virtualization both Another notable effort was the Xen project, which in 2003 used in the enterprise and high performance computing (HPC). The a jump table for choosing bare metal execution or virtual startup time of a virtualized environment is a key performance machine execution of privileged (OS) instructions [17]. Such metric for high performance computing in which the runtime of projects prompted Intel and AMD to add the VT-x [19] and any individual task is typically much shorter than the lifetime of AMD-V [18] virtualization extensions to the x86 and x86-64 a virtualized service in an enterprise context. In this paper, a instruction sets in 2006, further pushing the performance and methodology for accurately measuring the startup performance adoption of virtual machines. on an HPC system is described. The startup performance overhead of three of the most mature, widely deployed cloud Virtual machines have seen use in a variety of applications, management frameworks (OpenStack, OpenNebula, and but with the move to highly capable multicore CPUs, gigabit Eucalyptus) is measured to determine their suitability for Ethernet network cards, and VM-aware x86/x86-64 operating workloads typically seen in an HPC environment.
