09ntc Server Virtualization Session Slides
The document discusses the impact of virtualization on server management, highlighting benefits such as increased efficiency, reduced costs, and dynamic resource allocation. It explains how server virtualization uses a hypervisor to manage virtual machines, allowing for better load balancing and business continuity. The text also notes potential challenges and considerations for implementing virtualization in different organizational sizes.
09ntc Server Virtualization Session Slides
- 1. Virtualization What theDramatic Changes in Server Management Mean to Us
- 2. This is aTraditional Server Room
- 3. This is aVirtualized Server Room
- 4. On average, 10%of server processor is utilized per server*. *per IDC
- 5. Virtualization allows formaximized use and dynamic allocation of processing power
- 6. Energy Use andServer Budget are Reduced
- 7. Server Recovery andBackup is as Easy as…
- 8. Drag n’ DropBackup
- 9.
- 10. Mixture of OperatingSystems on One Server
- 11.

- 13. How It Works(1) Server virtualization uses a Hypervisor - a streamlined Operating System with connectivity, virtualization and management features. Intel and AMD include virtualization support on specific chipsets; this is required for some server virtualization products. Peter Campbell, Techcafeteria August, 2008
- 14. How It Works(2) Virtual machines (VMs) are loaded into memory by the Hypervisor. They emulate standalone servers. Users connect to VMs, but VMs can be copied and moved without interruption. Load Balancing and Fault Tolerance can be used to mirror VMs and insure business continuity.
- 15. Hypervisor Dynamically AdjustsVM Hosts to Best Use Resources
- 16. Load Balancing andAutomatic Failover Insures Stability
- 17. Reduced Costs, EnergyEfficiency, Manageability
- 18. This is allstill pretty new - assumptions about proper configuration and server requirements still vary. Virtualized databases can be impacted by conflicts between virtualization and caching. There is some debate about whether domain controllers should be virtualized. Smaller vendors might resist supporting virtualized applications; large vendors won’t. Potential Issues Peter Campbell, Techcafeteria August, 2008
- 19. Products Commercial VMWare(Server, Desktop, Fusion) Citrix Xen Server and Desktop Microsoft Virtual Server, WinServer 2008 Virtual Iron Open Source Xen (FOSS version of Citrix product) KVM VirtualBox Peter Campbell, Techcafeteria August, 2008
- 20. Questions Peter Campbell,Techcafeteria August, 2008
- 21. Virtualization Scenarios MatthewEshleman Director of Professional Network Services Community IT Innovators [email_address] www.citidc.com
- 22. Tools & TerminologyVirtualization Hypervisor Physical to Virtual Conversion Software Storage Area Network (SAN) iSCSI or Fiber Channel SAN Connection Storage Management (LUN) Backup & Disaster Recovery RPO & RTO
- 23. Backup & DisasterRecovery Backup What are the RPO and RTO requirements? Use existing backup to tape or disk Online backup services Backup appliances Disaster Recovery Part of business continuity Manual or Automated systems
- 24. Small Office VirtualizationSingle SBS Server Server out of warranty & out of space Additional services required Accounting server Terminal server Intranet etc
- 25. Small Office VirtualizationBenefits Preserve existing server Expand HW capacity Minimal user disruption Lower HW Costs Adds flexibility Risks Adds complexity Need to adjust backup plan Single point of failure
- 26. Mid Sized Consolidation2-6 existing physical servers Increasing application requirements Increasing availability requirements Maxing out electrical system Maxing out cooling system
- 27.
- 28. Mid Sized ConsolidationBenefits Lowered Hardware Costs Reduced Warranty Expense Reduced Energy Consumption Improved HW utilization Risks Solution needs to be appropriately designed Consider backup & disaster recovery requirements Adds complexity Server sprawl
- 29. Enterprise Virtualization Appropriatestarting at 4-8 physical servers High availability Highly flexible and expandable Dedicated IT staff Significant investment
- 30.
- 31. Enterprise Virtualization BenefitsLowered Hardware Costs Reduced Warranty Expense Reduced Energy Consumption Improved HW utilization High availability Flexibility Risks Software costs Complexity Management
- 32. Virtualization Conclusions Virtualizationcan be used in most cases Requires appropriate planning Provides additional flexibility and cost savings Relatively low barrier to entry
