1 SUSE Linux uutuudet - kuulumiset SUSECon:sta Olli Tuominen Technology Specialist [email protected]

2 2 SUSECon 13 4 days, 95 Sessions Keynotes, Breakout Sessions,Technology Showcase Case Studies, Technical Tutorials, Hands-on, Future Big Data, Cloud Infrastructure, High Availability, System Management and Tools, Virtualization and many other topics SUSECon Opening Reception, Sponsor Party, Conference Party = "free as in free beer" ;)

3 Big Data TT Deploy and Manage a Hadoop Cluster with SUSE Linux Enterprise Server and SUSE Manager

4 4 Hadoop Core Components

5 5 Typical Hadoop Distribution SUSE Linux Enterprise Server

6 6 Why SUSE Manager? Complements existing Hadoop Cluster Management Tools None of which handle the OS stack Auto installation (Provisioning) Patch management Configuration management System and remote management (Groups) Monitoring

7 Distributed Storage CEPH TT Petabyte scale out Rocks - Ceph as Replacement for Openstack's Swift and Co

8 8 CEPH What? So-called parallel distributed cluster file system Started as part of PhD studies at UCSC Public announcement in 2006 at 7th OSDI File system shipped with Linux kernel since Name derived from pet octopus cephalopods

9 9 Shared File Systems Short Intro Multiple server access the same data Different approaches Network based, e.g. NFS, CIFS Clustered Shared disk, e.g. CXFS, CFS, GFS(2), OCFS2 Distributed parallel, e.g. Lustre.. and CEPH

10 10 CEPH and Storage Distributed file system => distributed storage Does not use traditional disks or RAID arrays Does use so-called OSDs Object based Storage Devices Intelligent disks

11 11 CEPH The Full Architecture II CEPH Clients MDS Cluster Meta Data Operation Metadata I/O Data I/O User-space Linux kernel User POSIX VFS CEPH OSD Cluster

12 12 CEPH Block Device Aka RADOS Block Device (RBD) Second part of the kernel code (since ) RADOS storage exposed as block device (dev/rbd) qemu/kvm storage driver via librados/librdb Alternative to: Shared SAN/iSCSI for HA environments Storage HA solutions for qemu/kvm and Xen Shipped with SUSE Cloud

13 SUSE Manager TT Automating the Creation and Management of Cloud Workloads TT Integrate SUSE Manager with Your Other Monitoring Tools and Make It Part of Your ITIL Implementation TT Managing RH/CentOS with SUSE Manager TT Using SUSE Manager to Increase Security, Meet Compliance, and Reduce Risk

14 14 Why Choose SUSE to Support Red Hat? SUSE Linux Enterprise Server with Expanded Support is a full service maintenance and support offering covering: SUSE Linux Enterprise Server 11 Red Hat Enterprise Linux 5 and 6 CentOS 5 and 6 Focus: Mixed environment support, no vendor lock-in, consolidated support offering Binary compatible package updates for RHEL, CentOS Minimal disruption to existing Red Hat infrastructure Existing Installation media, profiles, and core image build processes are used going forward Savings could be as much as 50% of current spend

15 15 SUSE Manager CentOS Native Maintenance Updates obtained directly through the CentOS mirrors RPMs are built by CentOS. Patches (aka Errata) are built by CentOS. Info on patches is provided by CentOS. SUSE Manager server manage patches and software via custom channels and repositories SUSE Manager client works with native package management Packages imported with spacewalk-repo-sync

16 16 SUSE Manager Architecture for CentOS Native Update CentOS Mirror Firewall Clone-errata script SUSE Manager Server Management Provisioning Monitoring API Layer Patch Info YUM Repo SLES Systems CentOS Systems

17 SLE12

18 18 SUSE Technology Leadership Today Solaris Compete Leader in SAP & System z Tomorrow Exceed Unix and other OS Leader in Mission Critical Infrastructures

19 19 SUSE Linux Enterprise Lifecycle & Code Streams SLE10 SP4 SLE 11 SP2 SP3 SP4 SLE 12 GA SP1 13-year lifecycle For SLES 11 and SLES 12, 10 years general support, +3 years Long Term Support SUSE Linux Enterprise 12 Long Term Service Pack Support for every Service Pack

20 20 Best Managed Continuously Running Systems SUSE Linux Enterprise 12 Most Interoperable OS Made for Cloud

21 SUSE Linux Enterprise Reliability Tomorrow Continuously Running Systems (1) Snapshot / Rollback for full system Based on btrfs + Snapper + Bootloader integration Goal Have well known state where to go back Gives Peace of mind for Kernel Upgrades Service Pack installations 21

22 SUSE Linux Enterprise Reliability Future Continuously Running Systems (2) Migrate processes to more reliable memory/cpus Requires hardware support SUSE working with major CPU vendors and OEMs Goal Reduce Unplanned Downtime System and Applications survive Hardware Errors which otherwise would have been desastrous. 22

23 23 SUSE Linux Enterprise Systems Management Tomorrow System Installer Improved Workflow Reduced installation time and effort Next generation YaST based on Ruby Community participation Overhaul of network management framework Open Source Wicked solution Open and standardized interfaces

24 24 SUSE Linux Enterprise 12 Installer Workflow SUSE Linux Enterprise 11 Installation Setup Install without updates Wait Reboot Network Register Update Wait Reboot Services Log-in SUSE Linux Enterprise 12 Installation Setup Network Register Install with updates Wait Reboot Log-in

25 25 SUSE Linux Enterprise 12 Network Management Wicked Goal Cope with increasingly complex configurations Data Center and End Users Benefit Network configuration as a service Smooth adoption & migration Technical Attributes Architecture-independent Extensible Small footprint Event based
