Series: Hyper-v, not in my Datacenter part3


Gabrie heeft part3 gepost.

In part 3 of this series, I want to shed a light on the difference between the types of Migration in ESX and Hyper-V and the differences in storage between the both of them. Although I think most of the readers know the differences, I will start with a brief summary.

  • Hyper-V QuickMigration: When you want to move a running Virtual Machine from one host to another with as little downtime as possible, you can use QuickMigration. On host-A the VM will be suspended to disk, and then host-B will unsuspend the VM and run it.
  • Hyper-V & ESX Cold Migration: Moving a VM that is not running, to different host and/or different storage.
  • ESX VMotion: Moving of a running VM to a different host, without downtime.
  • ESX Storage VMotion: Moving the disks of a VM to different storage without downtime (VM doesn’t move).

Guest OS

After you installed your hypervisor you want to virtualize your physical servers on it. When doing the research for my presentation I was very surprised to find some strange limitations in which guest are supported with Hyper-V. Can you believe that not all Windows Server versions are supported? Well neither could I.

The guest OS support of Hyper-V:

  • Windows 2000 Server is only supported with SP4 and 1 CPU.
  • Windows 2003 Server is only supported with SP2 and 1 or 2 CPUs.
  • Windows 2008 Server is supported with 1, 2 and 4 CPUs.
  • and there is Linux support for SUSE Linux Server 10 sp1 / sp2 with only 1 CPU.

This does look quite reasonable at first glance, because these are current versions. True, but when looking at the ESX environment I work in now, we would not be able to virtualize as many servers as we have running on ESX right now

Gabrie van Zanten (www.gabesvirtualworld.com) is bezig met een serie over Hyper-V, not in my Datacenter.

I’ve written about Hyper-V and ESX is an objective view on how things are at the moment, but still it looks like the only thing I’m doing is Windows-bashing. I decided to dedicate a blog post to it, so everyone can find out for them self if my points are valid. The big question of my presentation is: “Which is better for my datacenter, Hyper-V or ESX?”.
I’m looking at both hypervisors to see which features they have that would make them suited for running in the datacenter discounting nice features that I would rarely use.  Here we go…….
