Reason to use Standard vs Enterprise vs DataCenter in VM

    Question

  • I am setting up a new server with WS2008R2 DataCenter with the Hyper-V role. Under the DataCenter use rights, I can create unlimited VMs using DataCenter or Enterprise or Standard editions.

    The question is this: If my expected use of the VM is within the feature set of Standard edition, is there a difference between installing Standard vs Enterprise vs DataCenter in a VM and using only those features? Put another way, does a DataCenter VM use more resources (disk, processor, memory) than a Standard or Enterprise VM if none of the Enterprise or DataCenter roles or features are added? Is there a benefit to overall resources to install Standard edition or does it matter if they are all DataCenter edition VMs?

  • It doesn´t metter. Basic installation is "same" in any version. Standard/Enterprise/Datacenter Edition use same number of resources...I think, that the best way is installing Datacenter Edition, because you can use advanced features in Hyper-V R2 SP1 - hot swap Processors, memory, etc.

  • I found with a lot of DC HyperV hosts that it really doesn't matter what you put on there as the VMs.  They will act the same.  The only reason I can think of to use the OS version that fits your server role, is if you were to ever need to V2P migration.  Then you might want a Standard Edition versus a Datacenter Edition for something small like a Domain Controller.  Might be a little difference in sizing of the VHDs, but it can't be but a tiny bit at most.

    Not that you would probably ever go V2P, but it's something to think about.

  • There is a misconception that Enterprise runs better than Standard and Datacenter is the most stable.  Each edition provides a set of features and services.  Take a look at this link to go over the various editions.
