Going by ur article, OEM will just not cut it. I have been trying to find similar information like urs and cannot do so. What is ur source? It is a very good article. We currently use Server standard on all physical servers.
We have CALs for 50 users licensed for server I just bought a new physical server, and a server standard open license. How could anyone get mixed up with this Post. This is exactly what I was looking for. A simple, Easily understood description of the licencing for Thanks Aidan. Skip to content. My recommendations are: Re-read this post if you do not understand it after the first or second reads.
To be honest, most of the questions have been from people who are just trying to make things complicated. Just license the hosts for the maximum number of Windows Server VMs that can ever run on that host, even for 1 second. It is that simple! It is used when talking about licensing a VM for Windows Server. When you buy a license for virtualisation you legally buy and assign it to hardware, not to VMs. There is no mobility with OEM.
You can assign more than 1 license to a host In other words, you license a host for the maximum number of Windows Server VMs that it could host.
Reminder: This applies even to you non-Hyper-V folks. Hi Aidan Thank for your long awaited license information for , I think its quite positive with enterprise going out and the other changes, although the death of the SBS server is bad news for us, but as you said it was to be expected considering the focus on office etc. I do have a question for you though: Hyper-V replica. In this scenario, purchasing DALs is a more cost effective solution. If however we had 10 users with a total of 20 devices , e.
Windows Server Foundation is available to OEMs Original Equipment Manufacturers only and therefore can only be purchased at the time of purchasing a n new hardware server. Windows Foundation edition supports up to 15 users. In addition, Foundation edition owners cannot upgrade to other editions. The Essential edition of server is available to OEMs with the purchase of new hardware and also at retail stores.
The user limit of this server edition is 25 and device limit is This means that a maximum of 25 users amongst 50 computers can access the Windows Server Essentials edition. For example, you have 20 users rotating randomly amongst 25 computers accessing the Server Essentials edition, without any problem.
A common question at this point is what if the organization expands and increases its users and computers? In these cases Microsoft provides an upgrade path allowing organizations to upgrade to the Windows Server Standard or Datacenter edition license and perform an in-place license transition.
Once the transition is complete, the user limitation, and other features are unlocked without requiring migration or reinstallation of the server. Companies upgrading to a higher edition of Windows Server should keep in mind that it will be necessary to purchase the required amount of CALs or DALs according to their users or devices. Administrators will be happy to know that it is also possible to downgrade the Standard edition of Server to the Essentials edition.
For example, it is possible to run Essential edition of Server as virtual machine utilizing one of two available virtual instances in Standard edition as shown in the figure below.
This eliminates the needs to purchase Essential edition of Server Download Now! 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? The server has 8 cores. Under the terms of licensing — you need to cover at least 16 cores. This will allow you to run 2 VMs. To run additional 2 VMs, you need to buy another set of core licenses. So if i have one VM in cluster of two nodes and fail happens VM migrates from first node to second host node.

Windows Server Licensing & Pricing | Microsoft – What do I get with my purchase?
Windows Server is an operating system that is widely used on physical servers and virtual machines including Microsoft virtualized servers in organizations.
Windows Server licensing became more complicated with the release of Windows Server compared to Windows Server Customers are confused with the new licensing model when trying to estimate Windows server licensing costs and buy the correct license.
This blog post covers Windows Server licensing including Microsoft virtualized server licensing to help you estimate Windows Server cost for a physical server and virtual machines. The licensing scheme of Windows Server is similar to Windows Server There are two types of licenses for Windows Server — server licenses and client access licenses CALs. Server licenses are core-based licenses.
The number of server licenses needed depends on the number of processors and processor cores. The number of client access licenses needed depends on the number of users or devices that will be connected to a server. Remote Desktop Protocol RDP is used to provide access to remote desktop services on the server for remote users. Note: This blog post provides an overview of licensing to familiarize you with Windows Server licensing. Licensing rules can change or be updated for newer product versions.
Refer to the Microsoft website and contact Microsoft sales managers before you buy licenses in order to avoid mistakes such as inadvertently violating the license agreement.
Windows Server uses a per-core licensing model for servers, which reflects the trend of producing powerful multi-core processors with a high number of CPU cores and the number of cores per processor increased significantly.
Server manufacturers are not increasing the number of processors in assembled servers, but are installing processors with more cores. The general rules that are applied to each physical server running Windows Server on a physical server as a host operating system or on virtual machines on this server are listed below.
The price for 8 dual-core licenses is the same as the price for a single core license. A license for 16 cores is the minimum license you can buy. Similarly, if a motherboard on a server has two sockets, but only one processor is installed, you only need to license all the cores of the installed processor. OSE is the operating system environment. This is a term that defines one instance of Windows Server running on a physical server or a virtual machine.
The virtual OSE term is used when Windows Server is running as a guest operating system Microsoft virtualized server on a virtual machine residing on a physical server. Licensed servers are the servers to which licenses are assigned. Note: The costs for one Windows Server R2 license for two processors equals the price for 8 dual-core licenses for Windows Server Windows Server cost is often a determining factor when choosing an edition.
Windows Server Essentials is windows server 2012 r2 standard licensing calculator free light edition suitable for small organizations and is licensed per server. There are many limitations in this edition.
Windows Server Essentials does not support virtualization. Client access licenses are not required. Windows server 2012 r2 standard licensing calculator free Server Essentials is well-integrated with Office hosted services. In other words, you can install Windows Server Standard on a host machine and run two virtual machines with Windows Server Standard as a guest OS.
Windows Server Standard running on a host used for virtualization as a hypervisor can be used only to install Hyper-V to run VMs. Using the host OS as a full-featured server with two virtual servers is not allowed. You cannot use three full-featured servers one physical and two virtual if you have the Standard license that covers two VMs and one physical server. The licensed Datacenter edition covers Windows Server installed on a host and allows you to run an unlimited number of virtual machines with Windows Server installed as a guest OS.
A Windows Server Essentials vs Standard comparison is outside the scope of this blog post. CAL licenses are required for both Standard and Datacenter editions.
For example, if you have licensed Windows Server Standard for all processor cores of a physical server and install Windows Server Standard on a host with the Hyper-V role enabled, then you can run two VMs with Windows Server Standard. If you need to run 4 virtual machines on a server, then you need to buy one more license a set of two-core licenses to cover all cores for this server the total number of VMs is four and Windows Server Standard is used in this example.
One Standard license covers two virtual machines. If you need to run windows server 2012 r2 standard licensing calculator free VMs on a основываясь на этих данных server that has two 8-core processors, you must buy 16 dual-core Standard licenses for Windows Server Two license подробнее на этой странице cover all cores twice and allow you to run 4 VMs. If you need to run an odd number of VMs on a windows server 2012 r2 standard licensing calculator free, you need to buy licenses for the next even number of VMs.
If you need to run 4 VMs on the same physical server that has two 8-core processors but with the Windows Server Datacenter license, you need to buy 8 dual-core Datacenter licenses for Windows Server VM licensing order: Physical cores must be licensed first and only after that virtual machines must be licensed.
Taking into windows server 2012 r2 standard licensing calculator free the current price for Windows Server licenses, it may be better to buy Windows Server Standard licenses if you are going to run up to 12 virtual machines on a single physical server.
If you need to run 14 VMs or more, the more rational decision is to buy Windows Server Datacenter. VM migration is especially needed if you run VMs in a cluster. In this case you need to buy the number of licenses to cover all VMs on all hosts for each physical server as if you are migrating all VMs from all hosts to one host.
In this case, each VM is licensed to migrate to any host. You can migrate a Windows Server license between physical servers once every 90 days. The Hyper-V virtual machine activation binds to the activated instance of Windows Server installed on a physical server that acts as a hypervisor. Virtual machines can be activated without an internet connection. There is no need to manage product keys for VMs.
Activation is preserved if licensed VMs are migrated between licensed hosts. We have two physical servers. Each server has windows server 2012 r2 standard licensing calculator free 6-core processor. Two VMs must run on each server. Windows Server Standard license can be used. We need to buy 8 dual-core licenses windows server 2012 r2 standard licensing calculator free each server because it is not possible to buy less than 8 double-core licenses to license a physical server even if there are less than 16 cores.
Note: VMs used in examples are running Windows Server of the edition mentioned in the corresponding example. Each server has one core processor. Four VMs must run on each server, and Windows Server Standard is installed on each physical server.
We have to buy 16 double-core licenses or two core licenses for each server. In total, we buy four core licenses for the whole Windows Server environment. The configuration is the same as in Example 2. Each server has 4 VMs and these Dreamboxedit windows 10 must be able to migrate between servers. As a result, we need to buy an additional 16 double-core licenses for each server. Finally, each server has 32 double-core licenses or four core licenses.
As a result, four additional core licenses must be bought for each physical windows server 2012 r2 standard licensing calculator free. Totally the equivalent of 80 cores must be covered on each server and there must be 40 double-core licenses or 5×16 core licenses for each server. There are three servers. The first server has two processors and each processor windows server 2012 r2 standard licensing calculator free 20 cores.
The second server has one core processor. The third server has one core processor. VMs running Windows virtual servers need to be migrated between hosts. Windows Server Datacenter is used in this case and, as such, we need to take into account the terms of Microsoft datacenter licensing. First of all, we must buy licenses for the server cores. Server 1. A total of основываясь на этих данных cores must be licensed 20×2.
The base core license covers 16 cores. We need to license 24 cores in addition to that and buy one more core license and two 4-core licenses. You can simply buy 20 double-core licenses. Server 2. You need to buy a base core license and one double-core license or just buy 9 double-core licenses.
Server 3. You need to buy two core licenses or 16 double-core licenses. Each server must be licensed to run the total number of VMs in the server group or cluster. The number 63 is odd, and we have to use the even number of 64 VMs. Each server must be licensed to run 64 VMs. As we use a licensed Windows Server Datacenter on each physical server, which allows us to run an unlimited number of VMs, no additional licensing is required after we have licensed all the CPU cores on each server.
Running VMs in a cluster makes your virtual environment more reliable, provides load balancing and high availability for virtual machines. The product automatically detects the host on which a VM is running and makes the VM backup.
Azure is the cloud platform developed by Microsoft that allows you to run virtual machines in the cloud. There are multiple ways to license Microsoft virtual machines running Windows Server in Azure. Windows Server licensing is included in Azure windows server 2012 r2 standard licensing calculator free.
You can create Windows Server VMs in Azure that is automatically licensed and charged windows server 2012 r2 standard licensing calculator free other services and cloud resources, such as using CPU, memory, storage, and network resources used by the VM. Hybrid licensing. You deploy a Windows Server VM in Azure, but manually activate and apply your own license you have bought for this purpose.
