SUSE Linux Enterprise 12 Technology Highlights 64-bit hardware is the future Virtualization Xen and KVM support 64-bit host; 64-bit and 32-bit guests Linux Kernel 3.12 based Systemd replaces SysVInit Boot process 10 64-bit kernels only Execution of 32-bit applications fully supported via 32-bit execution environment on top of 64-bit kernel Grub2 (bootloader) Dracut (initrd building)

What is systemd? systemd is a system and session manager for Linux, compatible with SysV and LSB init scripts systemd 11 Aggressive parallelization capabilities On-demand daemon activation Keeps track of processes using Linux Kernel Control Groups (cgroups) Able to auto-restart failing daemons Logging not only of syslog messages from services, but also messages services display on stdout Well documented in manual pages

Increase Uptime...

SUSE Linux Enterprise 12 Increase Uptime RAS High Availability System Rollback Live Patching Minimize downtime planned and unplanned 20

Prevent hardware downtime System Rollback RAS High Availability 21 Live Kernel Patching

SUSE Linux Enterprise 12 RAS - Overview Reliability, Availability, Serviceability Interaction of hardware and operating system Traditional UNIX capability SUSE is leading for RAS capabilities on Linux 22 Intel 64 architecture IBM POWER architecture

SUSE Linux Enterprise 12 RAS Benefits Choice of HW vendor System and applications survive hardware failure Integration into systems management frameworks Engineering excellence by early adoption of Kernel 3.x Future Migrate processes to more reliable memory/cpus 23

Reduce Operational Downtime RAS System Rollback High Availability 24 Live Kernel Patching

SUSE Linux Enterprise 12 System Rollback Goal: Go back to well-known system state Peace of mind for: Patch installation System admin tasks Components 25 ZYpp Btrfs Default filesystem Snapper Grub2 boot loader integration

SUSE Linux Enterprise 12 System Rollback New in SUSE Linux Enterprise 12 Extended system integration Support for Service Pack rollback Support for Kernel Upgrade Full system rollback 26

Manage without Downtime RAS Live Kernel Patching High Availability 31 System Rollback

SUSE Linux Enterprise Live Patching Technology kgraft What? Kernel Live Patching Designed and developed by SUSE Labs Ease of use: Builds on well known update processes Status? Currently being discussed and integrated Upstream (=Kernel community) Competitive Advantage? Works with zero execution interruption 32 As opposed to competition who stop the whole system (miliseconds to seconds range) when patching

SUSE Linux Enterprise Live Patching Kernel Live Patching Use Cases Mission Critical systems Help with deployment challenges Improve general availability Run until the next maintenance window No need to update all 10000+ systems at one shot, but be able to run until a specific state is reached See also: https://www.suse.com/communities/conversations/need-kgraft-2/ Caveat: Not all issues can be fixed using kgraft ; in special cases a reboot might be necessary 33
