Windows Server Licensing Guide — Posted: 5 days ago Hi Richard Ayars, Thanks for your post.

Similarly to the previous version Server , the latest Windows Server software is licensed per-core. A minimum of 16 cores must be licensed even if your server has fewer than this - and any additional cores must then be licensed via the 'Additional Core' packs Posted: 1 day ago For example, a user with a Windows Server CAL may access a Windows Server edition or a edition, however, they could not access a Windows Server edition. Mixing and matching Window Server s and CALs can become quite confusing and you should consult a licensing expert before configuring your licenses in such a manner.

Same is true for Virtual Desktops VMs , they are designed to be managed as a As part of the alignment with the Microsoft private cloud licensing model, Windows Server and System Center , as well as Enrollment for Core Infrastructure ECI , will have the same licensing and packaging structure. If you use the host as say, a file server , you will sacrifice one license and only have the ability to run 1 VM.

The versions are identical from a technical perspective with the only difference being virtualization rules. Posted: 1 week ago Windows Server R2 empowers businesses with enterprise-grade infrastructure management on a scalable, manageable budget. Integrate cloud services into your instance with state-of-the-art features, such as server virtualization and information protection, designed to help manage your workload and applications.

Licensing is the same regardless of the hypervisor being used. Licensing is based on host core count. Each host needs to be licensed. A minimum of 8 core licenses is required for each physical processor and a minimum of 16 core licenses is required for each server. Core licenses are sold in packs of two. October 4. Windows Server and licensing model is discussed in details in this article. Note the main points:. If you plan to use your physical server as a hypervisor on which several VMs with the Windows Server are running, you need to choose the OS edition depending on the number of VMs that will be running on your server.

For example, you have a dual processor server with total 16 cores. If you purchased 8 licenses of Windows Server Standard and licensed all the physical server cores, you are allowed to run up to 2 VMs with a Windows Server on a licensed physical host. The Datacenter license allows you to run an unlimited number of virtual OSs on a licensed host. What if you need to run more than two virtual machines on a server with a Standard license?

You will have to buy the required number of licenses based on the following consideration: one Standard license allows you to run 2 virtual machines. For example, you want to license a dual-processor 8 cores per CPU server with four virtual machines.

According to the Windows Server Standard licensing model, you need to buy 16 dual-core Window Server Standard licenses 2 sets of licenses closing all physical cores or 8 dual-core Datacenter licenses you can upgrade Windows Server edition without reinstalling.

Note that the licensing procedure is as follows: first the physical cores are covered, and then the virtual machine instances. According to the current Microsoft prices, it is worth to buy the Windows Server Datacenter edition if you are going to run 14 or more virtual machines on one physical host. If you use virtualization on your physical server with Windows Server , you can use the host OS only to maintain and manage the Hyper-V role and virtual machines.

You cannot install Windows Server on a physical server, run two VMs on it and get three full-fledged Windows server instances for your tasks. Software Assurance SA provides the right to transfer the product license between physical hosts for most Microsoft server products.

But Windows Server is an exception to this rule. According to the licensing agreement, the license can be migrated between the hosts once in 90 days. 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. Next we will discuss how to license SQL Server in more dynamic virtual environments where licensing requirements change frequently to meet shifting business needs. Many organizations have virtual computing environments that are dynamic—meaning that the virtual environments are spread across multiple virtual servers, and VMs are moved across these servers occasionally to reallocate resources.

In some cases, VMs are moved dynamically by the hypervisor. These dynamic scenarios can make software licensing more complicated, depending on how customers choose to license their virtual workloads. To help simplify licensing for these scenarios and to provide greater flexibility, Microsoft offers License Mobility within server farms, which allows licenses to move between servers along with the VMs.

License Mobility offers a great advantage to customers who license individual VMs and then need to reassign those licenses to different servers to accommodate moving workloads.

To help understand how License Mobility can be put into practice, consider our manufacturing company example. As the company grows, it adds more physical servers and begins to multiply its workloads across additional VMs.

With License Mobility, this company is able to reassign licenses to different servers within the server farm as often as is needed. So any time one of these VMs moves to a different server, the license moves with it. This can provide significant cost savings as well as simplicity in licensing. Without License Mobility, the company could only move licenses to a different server once every 90 days, which for this example means the company would need to maintain enough licenses on each server to cover the peak number of VMs that could be moved to the server at any time.

Another scenario in which License Mobility can help save costs is when organizations host virtualized workloads both in their datacenters and in the public cloud. License Mobility provides the flexibility to help address this need.

There are a few additional considerations to be aware of with License Mobility:. For organizations with a large number of VMs and complex, highly dynamic virtual environments, Microsoft offers the option to license for maximum virtualization. This means that when all of the cores on a server are licensed and covered with Software Assurance, a customer can deploy any number of VMs on the server. The key benefits of licensing for maximum virtualization are simplicity and potential cost savings.

Maximum virtualization ensures that customers are covered, without needing to be concerned with tracking individual VMs or the amount of power assigned to each VM. This is especially relevant for private cloud scenarios with a large number of VMs being moved dynamically between different physical servers, when self-provisioning is enabled, or when hyper-threading is turned on. The Enterprise DBC Appliance enables the consolidation of hundreds of databases into a single virtual environment through an integrated hardware and software solution.

In this scenario, an organization has deployed the base configuration of the Enterprise DBC Appliance, in which the physical servers are combined as a pooled virtual resource that supports a large number of VMs. Further complicating this scenario for licensing purposes is that the VMs are being moved dynamically between the server blades in the appliance to maintain peak performance.

By licensing all of the physical cores in the appliance, and covering those licenses with Software Assurance, the organization can deploy an unlimited number of VMs.

This can dramatically simplify licensing, as the organization can be assured that all VMs are correctly licensed, even when they are dynamically moved across the different servers in the appliance. The customer can also spin up as many new VMs as they need without ever needing to buy additional licenses. One important factor when licensing for maximum virtualization is to determine which use rights apply.

When deploying VMs on a server, the use rights of the most recent licensed version apply to every VM on the server. In scenarios like this one, it may still be possible to license VMs individually but it is likely to be difficult to manage. There are a few caveats to consider when licensing individual VMs in highly dynamic environments.

While customers can license up to four VMs with a single Enterprise Edition server license, as VMs are moved dynamically in this scenario, it would be impossible to ensure that all four VMs move together across the servers. In this case, License Mobility will not work and it is strongly recommended that one Enterprise Edition server license is assigned to a single VM.

In this case, it may be impossible to track virtual core-based usage if customers license individual VMs with core licenses. The following overview summarizes the software virtualization rights for current and prior versions, editions and licensing models of SQL Server software.

This summary should not be a substitute for careful review and understanding of your rights and obligations as described in your Microsoft Volume Licensing agreement and the Product Use Rights.

When licensing individual VMs under the Per Processor licensing model, all virtual processors v-cores supporting the VM must be licensed. No additional CALs are required. For licensing purposes, a virtual processor maps to a core when hyper-threading is turned off or hardware thread when hyper-threading is on.

To calculate the number of processor licenses required for each VM, divide the number of virtual processors in the VM by the number of physical cores or threads per physical processor.
