Enterprise Virtualization with Xen

  1. 1. <Insert Picture Here>Enterprise Virtualization With XenFrank Martin – Sr. Architect.EDCS Advanced Architecture Team
  2. 2. SAFE HARBOR STATEMENT
  3. 3. Early Stages – “Statelessness”• Breaking the logical/physical relationship between workload and its placement on hardware• Key to automation and modernization of a true “lights out Data Center and remote facilities management techniques• “Statelessness” The key to the adaptation of virtualization in the enterprise
  4. 4. Early Stages – Network Storage• In a stateless system, Network Storage is key to the architecture.• No local disk usage – everything is remotely mounted.• Most activity is concentrated on Server Virtualization, but the migration of data to a network storage-centric approach is crucial
  5. 5. Early Stages – Configuration Repository• “Statelessness” places the attributes of all workload into an outside repository.• Red Hat 5 – uses LDAP for this• EDCS uses an Oracle Database• Interfaces into Linux for all OS specifics ( hostname, network configs, mountpoints, users and software)
  6. 6. EDCS Standard Provisioning “Grid”• Stateless• PXE Booted• Network Disk Centric• All workload encapsulated into System Repository• BUT…. • Single OS to a single server (Server proliferation) • No Windows support • Big Flat Network
  7. 7. Enter: Server Virtualization
  8. 8. Project DAKOTA• Encapsulation of the computing environment• Network, Server, Disk all “Disposable”• Support of Windows alongside of Solaris and Linux
  9. 9. Project Dakota• Network Encapsulation: • SSL-VPN Tunnels and ACLS• Disk Encapsulation • Net Apps “Flex Cloning”• Server Virtualization • Xen
  10. 10. Project Dakota• Live Production – May 2005 • Linux only, Paravirtual only, on non-VT enabled hardware • 3 to 1 Collapse of server proliferation • As updates to Xen became available – new features were added: • March 2006 – Windows • October 2007 – Solaris Para-virtual • All Oracle software is in some form of Xen enabled virtualization ( not for external support )
  11. 11. Project Dakota• Current Status – Global IT and Oracle University • 240 Dell 1950s • Roughly 4,000 grid “instances”** (virtual machines) active at any given time • Wide variety of OS’es, Windows, Linux and now Solaris.
  12. 12. Oracle Grid-Based Computing• Grid-Based Storage • Oracle Automatic Storage Management• Grid-Based Server Clusters • Oracle Database • Oracle Middleware• Grid-Based Management • Oracle Grid Control Data Sales ERP Custom Warehouse Application Application Application Enterprise Manager Mid-Tier Server Clusters Real Application Clusters Automatic Storage Management

  14. 14. Oracle VM Oracle Fusion Oracle Non-Oracle Non-Oracle Database Middleware Applications Applications Applications Oracle Oracle Oracle Oracle or Red Hat Microsoft Enterprise Linux Enterprise Linux Enterprise Linux Enterprise Linux Windows Oracle VM• Oracle tested and supported server virtualization technology• Maximizes consolidation of Linux and Windows servers• Saves on power, cooling and space
  15. 15. Oracle VM Features• Simplified installation • Server install is a single CD • Server installs and configures in a minute• Faster deployment • Pre-configured Virtual Machine images of Oracle Database and Oracle Enterprise Linux• Live migration• Linux and Windows guest support • Oracle Enterprise Linux 4 and 5; • RHEL3, RHEL4 and RHEL5 • Windows 2003, Windows Server 2003 and Windows XP (on HV capable hardware)• Browser-based management • Create, clone, share, configure, boot, and Migrate virtual machines
  16. 16. Technology Enhancements• Enhanced and optimized Xen technology, addressing • I/O overhead • Memory overhead • Process Scheduling• Community involvement • Dedicated Xen development team • Contribute code and bug fixes to Xen • Members of Xen community at Oracle e.g. Dan Magenheimer • Member of XenSummit committee• Significant testing • Real-world testing with Oracle On Demand workloads • Testing with Oracle Validated configuration workloads
  17. 17. Opportunity: Enterprise Manager for Virtualized Infrastructure• Top-down management of applications running in virtualized environment• “Application aware” monitoring and administration of virtual resources• Dynamically grow & shrink resources to meet SLA objectives• Integration with oracle.com for live updates on best practices• Support for Lifecycle Management and ITIL driven flows• Integration with 3rd party management tools Data Sales ERP Custom WarehouseApplication Application ApplicationEnterprise Manager Virtual Machines Hosts/Virtual Servers Clusters & Storage
  18. 18. Opportunities• VM templates and virtual appliances for easier deployment• Vertical stack integrated• One management console for managing Apps down to the virtual environment
  19. 19. Summary• Oracle uniquely combines Oracle VM • Proven Grid capabilities • Server virtualization Data Sales ERP Custom Warehouse Application Application Application• Full virtualization strategy • Applications Mid-Tier Clusters • Data • Servers Oracle Real Application Clusters Enterprise • Storage Manager• Benefits • Maximized consolidation • Optimized agility Automatic Storage Management • High availability
