Server Virtualisation Part 2 – Moving Instances – How to License

 

We have rules on assigning and re-assigning and to fully understand the rights on Moving Instances we need to first fully clarify those rules

Assigning a license: To assign a license means simply to designate that license to one device. The purpose of this designation is to avoid sharing a license across multiple devices at the same time, once assigned a license, that server becomes the licensed device

Re-assigning a License: You may reassign a software license, but not on a short-term basis (i.e., not within 90 days of the last assignment). You may reassign a software license sooner if you retire the licensed server due to permanent hardware failure. If you reassign a license, the server to which you reassign the license becomes the new licensed server for that license.

Storing Instances: If a server is licensed, then stored or non-running instances of Windows Server and other Microsoft servers do not require separate licenses. The use rights permit you to store any number of instances under each license. You can also store instances on a large storage area network (SAN) or store instances on your servers without needing additional licenses for each instance.

Stored images can be shared and deployed across licensed devices

Some Virtualisation technology will dynamically move instances and this software will not take the license rules into consideration, so, from a compliance perspective, you need to keep a record of the "running" instances on each and every server, you also need to make sure you do not run an instance on a server box with no license assigned to it, as below

Windows Datacenter edition has UNLIMITED running OSE rights, so, if you license all your server boxes for Windows Datacenter, then you will not have to count the running OS instances or worry about running too many instances on a single server

 

Getting to Windows Datacenter edition

If you have Windows Standard Server or Windows Enterprise Edition AND Software Assurance coverage, you may "Step-Up" to Windows Datacentre edition for the price difference between the license and software assurance

 

Common Mistakes made with Virtualisation – All Incorrect

×One License = Unlimited Virtual Instances

×Windows server EE = 1 Host and 4 VMs which = 5VMs

×Dynamically assign license to devices running VM/Failover or move VMs to unlicensed devices

×Do not track how many VMs are “running”

×Do not license peak number of simultaneously running instances

  1. Emma, two more questions:
    1) You say that Datacenter servers have unlimited rights only when licensed for all CPUs. Is that only for virtualization, or Datacenter itself MUST be licensed for all CPUs. Pretend that I disable unlisened CPUs in BIOS/ Devie Manager. Doesn\’t it count?
     
    2) You say, I may store offline instances only on licensed devices. Can I store VHDs (offline instances) on Linux server without assigning a license to it? Or have a linux workstation with virtualization software and VHDs on it.. Offline but still on unlicensed device. I understand that I need to assign a license to RUN instances. But what about storing?

  2. Hi Alex
     

    Q1:
    Licensing a Server.  Before you run instances of the server software on a server, you must determine the required number of software licenses and assign those licenses to that server as described below.
    Determining the Number of Licenses Required.  You need a software license for each physical processor in the server.
    Server Repartitioning.  You may reassign licenses sooner than permitted above, when you:
    reallocate processors from one licensed hardware partition to another
    create two or more partitions from one licensed hardware partition
    create one partition from two or more licensed hardware partitions
    as long as (i) prior to repartitioning, each hardware partition is fully licensed, and (ii) the total number of licenses and processors remains the same.

    Q2
     

    Server- Creating and Storing Instances on Your Servers or Storage Media.  You have the additional rights below for each software license you acquire.
    ·         You may create any number of instances of the server software and additional software.
    ·         You may store instances of the server software and additional software on any of your servers or storage media.
    ·         You may create and store instances of the server software and additional software solely to exercise your right to run instances of the server software under any of your software licenses as described above (e.g., you may not distribute instances to third parties).
     
    Desktop- Creating and Storing Instances on Your Devices or Storage Media.  You have the additional rights below for each license you acquire.
    ·         You may create any number of instances of the software.
    ·         You may store those instances on any of your devices or storage media.
    ·         You may create and store instances of the software solely to exercise your right to run instances of the software under any of your licenses as described above (e.g., you may not distribute instances to third parties).

  4. Dear Emma
    Regarding this post, can you explain something about Windows Server 2008 Datacenter OEM and virtualization enviroments?
    Is it correct to use this kind of license in a VMware virtualization enviroment? Someone says that you can assign the DC OEM license to the ESX Host (if it is a dual socket HW) and you are free to activate unlimited Windows server 2008 VM instacens on that. Is that true? I know that is true for OLP License but OEM?

    Kind regards
