Not Virtualization for Virtualization’s sake.” Virtualization Strategy Oracle VM 3.x Oracle Linux OEM12c Xsigo Q&A 8 Virtualization Strategy Oracle VM 3.x Oracle Linux Oracle VM 3.x for x86 OEM12c Xsigo Q&A 9 Positioning • for both Oracle and non-Oracle applications • The only x86 server virtualization software supported Virtualization Strategy and certified for all Oracle software Oracle VM 3.x Oracle Linux • Almost no hypervisor overhead OEM12c Xsigo • Used in Oracle’s Engineered Systems Q&A (ODA, exadata, exalogic and exalytics) • Can be used to limit your license cost of Oracle Products 10 Positioning Continued • Oracle is in the “Challengers” quadrant. • This is a significant “jump” above Virtualization Strategy the x-axis Oracle VM 3.x • The move into the “Challengers” Oracle Linux quadrant was possible for 3 OEM12c primary reasons Xsigo 1) Strength of Oracle VM 3.0 Q&A 2) Integrated management 3) Solid customer momentum • Gartner even specifically states that Oracle VM use is growing amongst VMware customers 11 Oracle VM for x86 Architecture Virtualization Strategy Oracle VM 3.x Oracle Linux OEM12c Xsigo Ms.Win Ms.Win Solaris Q&A Linux 12 OVM Features • Assemblies & Templates Virtualization Strategy • (Secure) Live Migration Oracle VM 3.x Oracle Linux • Storage Connect Plugins OEM12c • Dynamic Resource Scheduling ( DRS ) Xsigo Q&A • Dynamic Power Management ( DPM ) • Anti-Affinity • High Availability 13 OVM Features – Assemblies & Templates • Unique to OVM • Pre-Built,Pre-configured and Production ready VM’s Virtualization Strategy Oracle VM 3.x • 100+ Templates available Oracle Linux • Easy and fast to deploy OEM12c Xsigo Q&A 14 OVM Features – Assemblies & Templates Continued Virtualization Strategy Oracle VM 3.x Oracle Linux OEM12c Xsigo Q&A 15 OVM Features – Assemblies & Templates Continued Virtualization Strategy Oracle VM 3.x Oracle Linux OEM12c Xsigo Q&A 16 OVM Features – (Secure) Live Migration • Better known as Omotion/Vmotion • SSL encryption at a button press Virtualization Strategy Oracle VM 3.x • Allows you to have Planned Downtime at ANY time Oracle Linux OEM12c Xsigo Q&A 17 OVM Features – Storage Connect Plugins • Makes it possible to perform storage tasks from within the OVM manager Virtualization Strategy Oracle VM 3.x Oracle Linux OEM12c Xsigo Q&A 18 OVM Features – DRS • Optimizes virtual machine CPU/Network resource utilization in a server pool. Virtualization Strategy Oracle VM 3.x Oracle Linux OEM12c Xsigo Q&A 19 OVM Features – DPM • Used to increase the consolidation ratio of VMs into least amount of OVM Servers required. Virtualization Strategy Oracle VM 3.x Oracle Linux OEM12c Xsigo Q&A 20 OVM Features – Anti-Affinity • ensures that specific virtual machines don’t run on the same OVM server. Virtualization Strategy • Usefull for Oracle VM 3.x Oracle Linux – Oracle RAC OEM12c Xsigo – Load balancing Applications Q&A – Relying on built-in redundancy of Applications 21 OVM Features – High Availability • Auto Restart on OVM Level Virtualization Strategy Oracle VM 3.x • Clusterware on OS Level Oracle Linux OEM12c Xsigo Q&A • RAC on Database level – Requires Rac licenses 22 Wait, What? Oracle RAC on OVM? Really? • It Works! • Fully certified and supported by Oracle Virtualization Strategy Oracle VM 3.x • Oracle does it! ( ODA, Exadata) Oracle Linux • But why do it? OEM12c Xsigo – Consolidate your RAC Servers Q&A – Create Virtual Clusters for demo/test/dev – Deploys fast – Use Hard-Partitioning 23 Licensing of Oracle Products on OVM • Soft-Partitioning ( default ) – License largest server in the pool Virtualization Strategy Oracle VM 3.x – f.e. 10 servers in pool running 3 vm’s with Oracle Oracle Linux Enterprise Edition software OEM12c Xsigo => need to license 3 largest servers. Q&A • Hard-Partitioning – Only on OVM accepted as a way to limit licenses – Works by pinning CPU’s to specific VM’s – Loose the ability to Live Migrate, use DRS or DPM 24 OVM Roadmap – What’s new? • Open Public Beta for OVM 3.2.1 • Support for Oracle VM Server for SPARC Virtualization Strategy Oracle VM 3.x • Health Monitoring & Statistics from within Manager Oracle Linux • Enhanced OVM Manager CLI and Web Services API OEM12c Xsigo • MySQL Database Support Q&A • Updated Dom0 Kernel in Oracle VM Server for x86 • Lots of other improvements 25 OVM Summary • Pricing – Free License, Pay for support Virtualization Strategy Oracle VM 3.x – Oracle Enterprise Manager included in support Oracle Linux • Strengths OEM12c Xsigo – Application-Driven Virtualization Q&A – all oracle products are certified and supported – Templates Templates Templates – Soft/Hard Partitioning to limit Oracle Licenses 26 How to continue from here • Read the user manual • Read the release notes Virtualization Strategy Oracle VM 3.x • Avoid Common pitfalls Oracle Linux – Check your hardware compatibility OEM12c – Check Bios Settings Xsigo – Choose PVM ( for now ) Q&A • Plan your setup • Start with Tier 2 ( dev/test ) • Don’t expect miracles • Feel free to Contact us 27 More Information • Home Page http://oracle.com/virtualization Virtualization Strategy Oracle VM 3.x Oracle Linux OEM12c • Blog Xsigo Q&A http://blogs.oracle.com/virtualization • Download http://edelivery.oracle.com/oraclevm 28 Virtualization Strategy Oracle VM 3.x Oracle Linux Oracle Linux OEM12c Xsigo Q&A 29 Positioning • Compatible with Redhat Enterprise Linux • Free to download, use and distribute Virtualization Strategy Oracle VM 3.x • Free source code, patching and binaries Oracle Linux • Oracle’s base development platform OEM12c Xsigo • Used in Oracle’s Engineered Systems Q&A • Dedicated Teams for QA/DEV and Support • Oracle now recommends only the Unbreakable Enterprise Kernel for all Oracle software on Linux 30 Oracle Linux Features • Unbreakable Enterprise Kernel Virtualization Strategy • Preinstall RPM’s Oracle VM 3.x Oracle Linux • Data Integrity OEM12c • Ksplice Xsigo Q&A • Cgroups 31 Oracle Linux Features – UEK • Closely tracks the mainline kernel • Tested with Oracle workloads and engineered Virtualization Strategy systems to ensure stability and performance.
