How Microsoft IT does server Virtualization and Hyper-V

So you want more evidence on Hyper-V, our friends at TechNet Edge have just posted this great interview.  Worth a watch.

In this interview we met up with Devin Murray (Group Manager) and David Lef (Technology Architect) who are in charge of implementing virtualization within Microsoft.  They’ve been running Hyper-V since it was in Beta in 2007 and have been running Hyper-V in production since January 2008.  In this interview, we cover the following topics:

  • History behind why and when we started implementing virtualization in the environment and what challenges we had.
  • [6:22] – Number of servers virtualized in Microsoft’s environment and goals of what percentage desired to be virtualized
  • [8:07] – Net business impact and how the team manages this area of the business
  • [9:54] – Current high availability stats (how many 9’s) and how to make this higher
  • [12:45] – Configuration of virtualization environment
    • High availability with Hyper-V
    • Why they determined the sweet spot was an 8 node cluster
    • [18:18] – Decision points between using VHDs versus Pass-through disks
    • [19:45] – What workloads he wouldn’t recommend using one disk type versus another in regards to performance
    • Downtime they’re seeing with quick migration
