There is no replacement for Windows Home Server. Just let me buy the quantity of licenses I need and do with them what I want. You should read the post again. Licensing for VMs is done at the host level, not at the VM level.

Great article, really helped me get to grips with licencing my forthcoming cluster. Is this correct? We are a small accounting firm that will be migrating from Server to R2 Standard in the coming weeks as our hardware and the apps we run are not yet certified on Can we buy a Server Standard license and downgrade to ? Would this allow us to then upgrade to at a later date?

I have an Windows Server Datacenter Retail license. Now i would like to run a physical server with Hyper-V only Hyper-V. So now i created a first virtual system. I used the same license from above two install the Windows Server Datacenter again. After that i created a second virtual system. Similar two the first i installed Windows Server Datacenter again with the same license.

Do I get same amount of virtual instances on any virtualization platform? Like I said, the rules are for virtualisation of Windows Server. The hypervisor used is irrelevant. Is the quad core count as 4 physical processors?

Each user is assigned to a specific workstation only. Processors are processors, and cores are cores. If a license covers processors then it covers processors. Thanks for this Aidan. I have windows server r2 Standard.

Can I use the same license to upgrade. Kindly suggest. Software Assurance Not Convered Thanks. This is simple and short: no. Windows Server R2 Essentials edition is available in retail stores around the world making it easy for businesses to install the new operating system without necessarily purchasing new hardware.

Windows Server R2 Essentials edition can run a single instance of virtual machine on Hyper V, a feature that was not available in Windows Server Essentials non-R2 edition. This single virtual machine instance can be Windows Server R2 Essential edition only, seriously limiting the virtualization options but allowing companies to begin exploring the benefits of the virtualization platform.

The Standard edition is able to support an unlimited amount of users, as long as the required user licenses have been purchased. We should note that the Standard edition supports up to 2 Virtual Machines. The Windows Server R2 Datacenter edition is the flagship product created to meet the needs of medium to large enterprises. The major difference between the Standard and Datacenter edition is that the Datacenter edition allows the creation of unlimited Virtual Machines and is therefore suitable for environments with extensive use of virtualization technology.

Before purchasing the Windows Server operating system, it is very important to understand the difference between various editions, the table below shows the difference between the four editions of Windows Server For example, a CAL assigned to a user, allows only that user to access the server via any device. Likewise, if a DAL is assigned to particular device, then any authenticated user using that device is allowed to access the server.

We can use a simple example to help highlight the practical differences between CAL and DAL licensing models and understand the most cost-effective approach:.

Assume an environment with Windows Server R2 standard edition and a total of 50 users and 25 devices workstations. In this case, we can purchase either 50 CAL licenses to cover the 50 users we have or alternatively 25 DAL licenses to cover the total amount of workstations that need to access the server.

Abstract Lenovo offers a broad range of Microsoft software offerings and solutions in different levels of integration to meet different customer requirements and business needs.

Introduction Microsoft and Lenovo have been partners for over 25 years. Did you know? Microsoft Subscription Licenses Microsoft subscription licenses are available via select countries enrolled in the Microsoft CSP program.

Below is a comparison between perpetual and subscription licenses from Microsoft: Table 1. Table 2. Microsoft Azure Reserved Instances Microsoft Azure platform also provides a pre-paid discounted variation of a selected number of Azure Cloud Services. Noted that there is a 10 core max for only one CPU. Standard Edition: Ideal for customers with low density or minimally virtualized environments.

Datacenter Edition: Ideal for highly virtualized and software defined datacenter environments. Pre-Install — The OS is pre-installed onto the Lenovo server at manufacturing and the OS install media is included with the server from manufacturing for possible subsequent customer self-install.

Table 6. Core based licensing: Windows Server Standard and Datacenter The licensing of Windows Server Standard and Datacenter editions based on a per physical processor basis. Servers are licensed based on the number of processor cores in the physical server. All physical cores in the server must be licensed. A minimum of 16 core licenses is required for each server. A minimum of 8 core licenses is required for each physical processor.

For every two additional OSEs, all the cores in the server have to be licensed again. Table 7. CALs are assigned to a user in Active Directory. CALs are tracked and enforced by the license server. CALs are tracked but not enforced by the license server. CALs can be tracked regardless of Active Directory membership. CALs cannot be tracked within a workgroup. You cannot revoke any CALs. Temporary CALs are valid for days. This eliminates the needs to purchase Essential edition of Server Download Now!

Unlike Windows Server Essentials non-R2 , you can now run a single instance of a virtual machine. The server licensing rights have been expanded, allowing you to install an instance of Essentials on your physical server to run the Hyper-V role with none of the other roles and features of the Essentials Experience installed , and a second instance of Essentials as a virtual machine VM on that same server with all the Essentials Experience roles and features.

Definition of a socket is a CPU or physical processor. Logical cores are not counted as sockets. A single license of Standard and Datacenter edition covers up to two physical processors per physical server. Standard edition allows up to 2 virtual instances while the Datacenter edition allows unlimited number of virtual instances. For example, a Windows Server R2 Standard edition installed on a physical server with one socket CPU can support up to two instances of virtual machines.

These virtual machines can be Server R2 Standard or Essentials edition. Similarly, if you install a Windows Server R2 Datacenter edition , then you can install an unlimited number of virtual machines.

Scenario 2 : Install Server Standard Edition on a physical server with 1 physical processor, running 8 instances of virtual machines. A total of 50 users will be accessing the server. How to license a virtualization farm, in which VMs can move between hypervisors host OSs? In this scenario, you will have to buy that number of licenses for each physical server covering the maximum number of virtual machines that can be run on it at any time including the high availability scenarios when all virtual machines of the farm are moved to the one of the hosts.

In the case of the Datacenter edition, one set of licenses will be sufficient for each physical host, covering all cores in the minimum configuration, 8 Datacenter dual-core licenses. Since this license allows you to run an unlimited number of VMs. Therefore, you should choose the Windows Server license depending on the maximum number of VMs on a single host. Below are some examples of calculating Windows Server licenses for physical hosts when using virtualization.

Example 1. There is a Hyper-V cluster of 5 hosts. Each server has 2 processors with 20 cores. Each will run 10 virtual machines. Because 5 servers are united into HA Hyper-V cluster, which means that up to 50 virtual machines can be running potentially on each host during VM migration failover.

Accordingly, it is more profitable to purchase the Datacenter licenses. Example 2. The branch office has 1 server with 2 sockets with 4 cores each, on which 4 virtual machines are running. How many Windows Server licenses do I need to purchase?
