Planning virtualization of servers with Hyper-V, part 1

For a succesful implementation of virtualization of your existing servers you need to plan your moves carefuly. To keep things short, these are the steps you need to take:

  1. Determine the Virtualization Scope
  2. Create the List of Applications
  3. Determine Resource Requirements
  4. Select the Backup Approach for Each Application
  5. Applying Fault Tolerance
  6. Summarize and Analyze the Application Requirements
  7. Select a Form Factor for the Hosts
  8. Map Guests to Hosts
  9. Determine the Host Backup Approach
  10. Design Fault Tolerance
  11. Design the Storage Infrastructure
  12. Design the Network Infrastructure

Starting with step 1, determining the virtualization scope, you have a few options:

  1. Enterprise Deployment - this option involves deployment of virtualization technology to the entire organization, including corporate data centers.
  2. Hub Deployment - this option involves deployment of virtualization technology to one or more hub locations. Hubs are physical locations where there are concentrations of users, computers, and/or network connectivity. Resources within the hub may be provided to additional satellite locations.
  3. Satellite Deployment - this option involves deployment of virtualization technology to one or more satellite locations. Satellite locations are smaller than enterprise or hub environments and often have limited network connectivity to the rest of the environment because of bandwidth constraints.

In part 2, i will examine the next step, creating the list of applications that need to be virtualized.
