2 Introducting myself Software engineering and Unices since 1988 Mostly Configuration Management Systems (CMS), Build systems, quality tools, on multiple commercial Unix systems Discover Open Source & Linux (OSL) & first contributions in 1993 Full time on OSL since 1995, first as HP reseller Currently: Technology Architect on OSL for the HP/Intel Solution Center, Grenoble OSL HP Advocate EMEA OSL HP Profession Lead Solutions Linux Conference board member MondoRescue, Dploy.org, Project-Builder.org project lead, mrepo, tellico, rinse, fossology contributor Mandriva, Fedora packager

3 Outline Introduction Conceptual Feature Deep Dive Futures 3 Set Overview

4 Conceptual Overview 4

5 Charter enable Linux as a managed service facilitate Linux adoption in the enterprise encompass engineering and delivery aspects support provisioning and complete life cycle utilize best of breed tools and processes follow open source development and support models established defacto internal IT standard encourage choice 5

6 Abbreviated Historical Time Line 1999 q3 - Linux is strategic at hp 2000 q4 - project is formed, corporate waystation setup 2001 q2 - version 1.0 Adelie : RedHat 2002 q1 - version 1.2 : Debian 2003 q4 - version 2.0 African : rewrite, Fedora, RHEL, apt4rpm 2004 q3 - version 3.0 Chinstrap: SuSE, SLES, NLD 2005 q3 Open Sourced under GPL 2005 q4 version Current version 4.x Emperor : rewrite, install packaging, yum 6 : Ubuntu

7 Current Status Distributions 7 CentOS, Fedora, RHEL, ScientificLinux, VMware-ESX Debian, Ubuntu OpenSUSE, NLD/SLES/SLED Multi Architecture I386, x86_64, (hppa, ia64) Deployments 25,000 internal (unique MAC address) ~10,000 / year (since 2007) via

10 Architecture Major Deployment Components Design Station where users interacts with SystemDesigner WebUI Installation Media Repository (aka waystation) Target Install System(s) ultimate objective 11

13 Feature Set 14

14 Feature Set generate boot images for network or local media based installations, by managing design profiles save profiles that store custom installation preferences for later re-use retrofit already deployed systems by overlaying bundles of packages for other value-add components replay, from a desired system, recreate the boot image for deployment on another system 15

15 16

16 Profile Management Software selection distribution-defined sets value-add modules/bundles Disk partitioning simple or advanced Patching mechanism ( built-in, apt, yum ) at first build, subsequent frequency Post-install 17 scripting

17 Boot Image Preferences fixed or DHCP target media source (network waystation or local), protocol network adapter Localizations media source ( network waystation or local ) time zone, language Profile (or equivalent selections) Passwords, summary, download page 18

19 Retrofit Selection of value-add bundles Summary, download page 20

20 Waystation Deployment Tactics Same or distinct host from SystemDesigner instance Typical alternatives reference another's maintained repository default configured setup of SystemDesigner create localized repository mirror another / public repository to minimize network latency obtain ISO media, create local indices 21

21 Deep Dive 22

22 Deep Dive Hosting requirements Under the hood Extending SystemDesigner Modules Alternate Configurations Integrations Restricting 23 SystemDesigner

23 Hosting requirements Hardware minimal, anything capable of running supported operating system and applications Operating System current support for Linux only (loopback mount, mkisofs) Application 24 common commands perl, web server (Apache) mkisofs, palo, sudo (depending on versions and architectures vended)

24 Under the hood SystemDesigner a Perl, CGI application that typically runs under Apache WebUI a front-end script for each mode a set of back-ends for bootimage creation, corresponding to Kickstart, Autoyast, Preseed specifics per distribution/revision/architecture set of configuration files overall configurable settings 25

25 Alternate Configurations Overlay of main configuration + select overrides simple text file referenced across modes via <url>?defs=someoverridefile Provides ability to use same codebase for multiple audiences, yet present different environment 26

26 Modules Hierarchy of value-add components Module ( repository ) Bundle ( collection of one or more packages) Package (discrete installable item ) Specific to distribution/revision/architecture or can be wildcarded Referenced by main configuration file, and included in WebUI as relevant at runtime 27

27 Integrations Since modular, can readily be integrated with other processes SystemDesigner can be called from HP-SIM and vend images compatible with Smart Start Scripting Toolkit ( SSSTK ) => discovery, design, install on first boot Conceptually easy to integrate with generic PXE installation environment Future work to integrate, or at least interoperate with MondoRescue, and other FLOSS components 28

28 Monitoring services (HP SIM / Nagios / OCS) Internet services (IP management, software mirroring, network boot support) Automatic Deployment and imaging services (, MondoRescue, mrepo) Hardware configuration services Linux Distributions Hardware Platforms Virtual Platforms (Proliant / Integrity / Carrier Grade) (Xen / VMWare / QEMU)

29 Restricting SystemDesigner Using main configuration file, can specify default settings that become default selections specify show only selections to streamline interface using alternate configurations, can effectively filter down ( or provide superset ) of options 30

30 Futures 31

31 Futures Plugins for OpenQRM (done) Whitepaper for integration of HP SIM, SSSTK,, and PSP (about to publish) Add Mandriva as a supported distribution, investigating others Integrate with Mondorescue, network services as part of dploy.org <insert 32 your suggestions here> :)
