Ubuntu Server for IBM Z and Linuxone Ubuntu Server for IBM Z and LinuxONE Introduction and Overview Frank Heimes, Tech. Lead for Ubuntu on s390x, Canonical Ltd. Ubuntu on Big Iron: ubuntu-on-big-iron.blogspot.de Canonical We are the company behind Ubuntu. Where is the name Ubuntu coming from? ubuntu |oǒ'boǒntoō| Ubuntu is an ancient African word meaning ‘humanity to others’. It also means ‘I am what I am because of who we all are’. The Ubuntu operating system brings the spirit of Ubuntu to the world of computers. Ubuntu http://www.ubuntu.com/about/about-ubuntu Ubuntu Server for IBM Z and LinuxONE (s390x) Design Philosophy ● Expand Ubuntu’s ease of use to the s390x architecture (IBM Z and LinuxONE) ● Unlock new workloads, especially in the Open Source, Cloud and Container space ● Offer a radically new pricing approach (drawer-based pricing) ● Consequentially tap into new client bases ● Exploit new features and components faster - in two ways: ○ hardware: compiled for zEC12 and up ○ software: latest kernels, compilers and optimized libraries ● Provide party with other architectures ○ Release parity ○ Feature parity ○ Uniform user experience ○ Close potential gaps ● Open source - is collective power in action ● Upstream work and code only - no forks Ubuntu Release Naming Scheme The official name of an Ubuntu release is ‘Ubuntu x.y’ with ‘x’ representing the year (minus 2000) and ‘y’ representing the month of eventual release within in that year. So Ubuntu's first release, made available in 2004 October (October is the 10th month) was Ubuntu 4.10. Since the actual release date is not known until it's ready and humans tend to prefer names rather than numbers, a set of code-names are used by developers and testers during the buildup to a release: Adjective Animal Version Adjective Animal Version Adjective Animal Version Warty Warthog 4.10 Jaunty Jackalope 9.04 Saucy Salamander 13.10 Hoary Hedgehog 5.04 Karmic Koala 9.10 Trusty Tahr 14.04 LTS Breezy Badger 5.10 Lucid Lynx 10.04 LTS Utopic Unicorn 14.10 Dapper Drake 6.06 LTS Maverick Meerkat 10.10 Vivid Vervet 15.04 Edgy Eft 6.10 Natty Narwhal 11.04 Wily Werewolf 15.10 Feisty Fawn 7.04 Oneiric Ocelot 11.10 Xenial Xerus 16.04 LTS Gutsy Gibbon 7.10 Precise Pangolin 12.04 LTS Yakkety Yak 16.10 Hardy Heron 8.04 LTS Quantal Quetzal 12.10 Zesty Zapus 17.04 Intrepid Ibex 8.10 Raring Ringtail 13.04 Artful Aardvark 17.10 The development codename of a release takes the form "Adjective Animal". So for example: Warty Warthog (Ubuntu 4.10), Hoary Hedgehog (Ubuntu 5.04), Breezy Badger (Ubuntu 5.10), are the first three releases of Ubuntu. In general, people refer to the release using the adjective, like "warty" or "breezy". The names live on in one hidden location---the archive release name in /etc/apt/sources.list and seen on the download mirror network. https://wiki.ubuntu.com/DevelopmentCodeNames https://en.wikipedia.org/wiki/List_of_Ubuntu_releases Consistent Release Cycle 5 years long term support (LTS) - every 2 years 9 month support for non-LTS / development releases - every 6 month 14.04 14.10 15.04 15.10 16.04 16.10 17.04 17.10 18.04 18.10 19.04 https://wiki.ubuntu.com/Releases 18.10 https://wiki.ubuntu.com/LTS https://en.wikipedia.org/wiki/List_of_Ubuntu_releases Ubuntu 18.04 LTS 5 years 1817.10 non-LTS months aka 17.04 development in development 16.10 releases end-of-life in service Ubuntu 16.04 LTS 5 years 15.10 15.04 14.10 Ubuntu 14.04 LTS 5 years Extended Support / ESM (Security only), like for Ubuntu LTS 12.04: https://insights.ubuntu.com/2017/03/14/introducing-ubuntu-12-04-esm-extended-security-maintenance/ Ubuntu 16.10 / Yakkety - EOL Ubuntu 16.10 (Yakkety Yak) reached End of Life on July 20 2017 https://lists.ubuntu.com/archives/ubuntu-security-announce/2017-July/003954.html Ubuntu 17.04 / Zesty ● Released on Thursday the 13th of April ('4'th month, year 20'17' → 17.04) ● Ubuntu Server non-LTS / development release ● Updates on many core packages, including 4.10-based Kernel, gcc 6.3 (tests and sample compiles with gcc 7 already started), KVM-Qemu 2.8, Libvirt 2.5, LXD 2.12, Snapd 2.24, Postgresql 9.6, Puppet 4.8, MySQL 5.7, Go/golang 1.7 and 1.8, PHP 7, Python 3.5(.3), glibc 2.24, binutils 2.28, apt 1.4, Nginx 1.10, OpenSSH 7.4, Docker (docker.io) 1.12(.6), Docker-Compose 1.8, flannel 0.5.5 - just to name a few ● Some s390x specific information to notice are: ○ added flannel (1642631) ○ added libgoogle-perftools4 (1643975) ○ kernel message catalogue for s390x integrated (1628889) ○ upgrade to latest genwqe (1664565) and zlib (1664595) ○ upgraded libica to 3.0.2 (1638885) ○ upgraded s390-tools to 1.37+ (1656809) ■ incl. upgrade s390tools to version 1.37.1 changes ■ incl. conversion of some s390-tools shell scripts to C (1657166) ○ opencryptoki rebased to 3.6.2 (1638879) ○ added support to ensured stable PCI Identifiers using UIDs (1644504) ○ added support to read PCI FMB length (1658727) ○ added support for DASD channel-path aware error recovery (1644537) ○ added support for toleration of newer crypto hardware for z Systems (1644533) ○ added support for concurrent multiple domains for crypto adapter (1655909) Ubuntu 17.10 / Artful - TBD ● The codename for the 17.10 release is 'Artful Aardvark' or in short 'Artful': https://launchpad.net/ubuntu/artful ● https://wiki.ubuntu.com/ArtfulAardvark/ReleaseSchedule Alpha 1: June 29th;

    Introducing Linux on IBM z Systems IT simplicity with an enterprise grade Linux platform Wilhelm Mild IBM Executive IT Architect for Mobile, z Systems and Linux © 2016 IBM Corporation IBM Germany What is Linux? . Linux is an operating system – Operating systems are tools which enable computers to function as multi-user, multitasking, and multiprocessing servers. – Linux is typically delivered in a Distribution with many useful tools and Open Source components. Linux is hardware agnostic by design – Linux runs on multiple hardware architectures which means Linux skills are platform independent. Linux is modular and built to coexist with other operating systems – Businesses are using Linux today. More and more businesses proceed with an evolutionary solution strategy based on Linux. 2 © 2016 IBM Corporation What is IBM z Systems ? . IBM z Systems is the family name used by IBM for its mainframe computers – The z Systems families were named for their availability – z stands for zero downtime. The systems are built with spare components capable of hot failovers to ensure continuous operations. IBM z Systems paradigm – The IBM z Systems family maintains full backward compatibility. In effect, current systems are the direct, lineal descendants of System/360, built in 1964, and the System/370 from the 1970s. Many applications written for these systems can still run unmodified on the newest z Systems over five decades later. IBM z Systems variety of Operating Systems – There are different traditional Operating Systems that run on z Systems like z/OS, z/VSE or TPF. With z/VM IBM delivers a mature Hypervisor to virtualize the operating systems.

    WHITEPAPER The Rockstar in Your Data Center: The IBM Z Mainframe Table of contents Why read this? 3 Key takeaways 4 Executive summary 5 The IBM Z platform does what? 8 Next steps and additional resources 17 Whitepaper The Rockstar in Your Data Center: The IBM Z Mainframe ROCKETSOFTWARE.COM 2 Why read this? Some CIOs may think it’s time to retire their IBM Z® mainframe. They may think the technology has become outdated, they may not understand the full benefits they provide, or both. The mainframe has design strengths that, today, make it invaluable to IT organizations for hosting their most important, mission-critical applications. These applications typically include customer order processing, financial transactions, production and inventory control, payroll, as well as many other types of computationally intensive and high-volume tasks. This whitepaper demonstrates why IBM Z mainframes are the best choice to be the bedrock for critical, “can’t fail” processing tasks, and why, over the long term, they deliver among the best value in the IT ecosystem. Whitepaper The Rockstar in Your Data Center: The IBM Z Mainframe BACK TO TABLE OF CONTENTS ROCKETSOFTWARE.COM 3 Key takeaways Don’t automatically dismiss IBM Z when making strategic decisions about your current and future IT environment. It continues to have significant market and competitive strength, and IBM makes sure it works with the latest technologies, including cloud computing and open-source tools. It’s a key innovation player that drives better ROI on core infrastructure while supporting the latest advancements in technology and user experience. The at-risk platform in large organization data centers is not the mainframe.
