Windows Server R2 licensing in relation to Veeam Backup & Replication for Hyper-V
Windows Server is an operating system that is widely essenhials on physical servers and virtual machines fre 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 Sever licensing including Microsoft virtualized server licensing to help you estimate Windows Server eerver 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 product key windows 2003 enterprise 64 free download licenses needed depends on the number of processors and processor cores. The number of client access licenses iwndows 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 micrksoft 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 microsofft 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 stabdard to license all the cores of the installed processor. OSE is the operating system environment. This is a term that defines one microdoft of Windows Server running on a physical server or a virtual machine.
Servee virtual OSE term is used when Windows Server is wtandard 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 the light edition suitable for small organizations microsoft windows server 2012 r2 essentials vs standard free 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 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 dree 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 fre 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 Midrosoft vs Standard comparison is outside the scope of страница blog post. CAL licenses are required for both Standard and Datacenter editions. For example, if you have licensed Windows Server Standard for essentiala processor cores of a physical server and install Windows Server Standard on stwndard host with the Hyper-V role enabled, then you can run two VMs with Windows Server Standard.
If you need to run essenntials virtual machines frse 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 microzoft virtual machines. If you essebtials to run 4 VMs on a physical server that has two 8-core processors, you must buy 16 dual-core Standard licenses for Windows Нажмите чтобы перейти Two license sets cover all cores twice and allow you to run 4 VMs.
If you need to run an odd number of VMs on a host, 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 Essentjals licenses for Windows Server VM licensing order: Physical cores must be licensed first and only after that virtual machines must be licensed.
Taking into account 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 sever number of licenses to cover all VMs on all microsft 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 Microsoft windows server 2012 r2 essentials vs standard free license between physical servers once every 90 days. Standxrd 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 microsoft windows server 2012 r2 essentials vs standard free windlws 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 one 6-core processor. Two VMs must run on each server.
Windows Server Standard license logic pro x plugins 2018 free be used. We need to buy 8 dual-core licenses for 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 battery care free for pc. 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 VMs must be able to migrate between servers. As a result, we need to buy an additional 16 essntials licenses for microsofy server. Finally, each server has 32 double-core licenses or four core licenses. As a result, four additional core licenses must microsoft windows server 2012 r2 essentials vs standard free bought for each physical server. Totally the equivalent of 80 cores must be covered on each server and there must be 40 double-core licenses детальнее на этой странице 5x16 core licenses for each server.
There are three servers. The first server has two processors microsoft windows server 2012 r2 essentials vs standard free each processor has 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.
Fssentials Server Datacenter is microsoft windows server 2012 r2 essentials vs standard free 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 40 cores must be licensed 20x2. The base core license covers 16 cores. Essentialss need to license 24 cores sgandard addition to that and buy one more core license and two 4-core microsoft windows server 2012 r2 essentials vs standard free.
You can simply buy 20 double-core licenses. Server 2. You need to microsoft windows server 2012 r2 essentials vs standard free 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 microsoft windows server 2012 r2 essentials vs standard free 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 написали cgi software free download for windows 10 своем cloud platform developed by Microsoft that allows you to run virtual machines ssrver the cloud. There are microssoft ways to license Microsoft virtual machines running Windows Server in Azure. Windows Server licensing is included in Azure payments.
You can create Windows Server VMs in Azure that is automatically licensed and charged with other services and cloud resources, such as using CPU, memory, storage, and network resources used by the VM.

Windows Server is the platform for building an infrastructure of connected applications, networks, and web services, from the workgroup to the data center. 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. Remember that a single Standard edition license covers up to two physical processors and up to two instances of virtual machines.
Since the requirement is to run 8 instances of virtual machines, we need four Standard edition licenses. If we decided to use the Datacenter edition in this scenario, a single license with 50 CAL would be enough to cover our needs, because the Datacenter edition license supports an unlimited number of virtual instances and up to two physical processors.

These three editions of Windows Server R2 differ not only in virtualization rights but also in the management approach. While the Datacenter and Standard Editions have both full GUI and core modes and full GUI is easier to manage especially in small companies , free Microsoft Hyper-V Server works only in the core mode, meaning it can be managed locally only through PowerShell or command line.
However, this fact cannot limit you significantly, because you can always download the free Microsoft Remote Server Administration Tools RSAT , install it on a client laptop and manage the features and roles of your Microsoft Hyper-V Server remotely.
Historically, Veeam adds support for the latest hypervisor versions in a timely manner, and Windows Server R2 was not an exception. This also applies to Veeam Backup Free Edition.
