  3. 3. The Fundamentals of Virtualization<br />Traditional Computing<br />
  4. 4. The Fundamentals of Virtualization<br />Computing in a Virtualized Environment<br />
  5. 5. The Fundamentals of Virtualization<br />Type 1 – Hypervisor (Bare Metal) <br />
  6. 6. The Fundamentals of Virtualization<br />Type 2 – Hypervisor (Hosted) <br />

  9. 9. The Fundamentals of Virtualization<br />Features of Virtualization<br />
  10. 10. The Fundamentals of Virtualization<br />Transparent sharing of resources<br />Memory, CPU, Network, Disk<br />Hardware is decoupledfrom operating system<br />Underlying hardware becomesa pool of resources<br />
  11. 11. The Fundamentals of Virtualization<br />Live Migration<br />Virtual servers can be moved between physical hardware while running<br />Allows for maintenance on hardware without downtime<br />
  12. 12. The Fundamentals of Virtualization<br />Management<br />Single point of management for all of your virtual machines<br />Allows for building of custom templates for rapid deployment<br />Snapshotting technologies allow for block level rollbacks in event of failure<br />
  13. 13. The Fundamentals of Virtualization<br />High Availability<br />Virtual Servers can be set to boot on alternate server in event of hardware failure<br />Two instances of same virtual server can be running on multiple hosts<br />
  14. 14. The Fundamentals of Virtualization<br />Why Virtualize?<br />
  15. 15. The Fundamentals of Virtualization<br />Server Sprawl<br />On average, physical servers run between 5-20% utilization.<br />The power, space, and cooling costs can’t justify the servers workload.<br />
  16. 16. The Fundamentals of Virtualization<br />How to mitigate Server Sprawl?<br />Server Consolidation<br />Host multiple operating systems and environments on single piece of hardware.<br />
  17. 17. The Fundamentals of Virtualization<br />Consolidation Ratios<br />Consolidation ratios for physical to virtual machine migrations can range from 10:1 up to 30-40:1.<br />
  18. 18. The Fundamentals of Virtualization<br />Significant Cost Savings<br />Power<br />Cooling<br />Space<br />Hardware costs for new servers<br />Operational efficiency <br />
  19. 19. The Fundamentals of Virtualization<br />Server Downtime<br />Keep your organization running optimally leveraging the features of virtualization.<br />
