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 4 VMs on a physical server that has two 8-core processors, you must buy 16 dual-core Standard licenses for Windows Server 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 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 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 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. If you purchase Standard edition today but find you need to expand the virtualization capacity of your licensed server, you can do one of the following: Purchase additional Standard edition licenses and assign them to the same physical server, giving you the rights to run additional instances of Windows Server.
The server must have the appropriate number of licenses assigned to it to ensure coverage of all of the virtual OSEs that are running at any given time. Purchase a Software Assurance Step-up license to Datacenter edition, changing the license to a higher edition that allows unlimited virtual OSEs.
To use this benefit, your underlying license must have Software Assurance. With the Windows Server R2 Standard edition licensing model, you can grow your virtualization environment by either buying a step-up license to Datacenter edition if you have Software Assurance, or by simply buying additional Standard edition licenses and assigning them to the same physical server.
For example, if you have a two-processor server and want to run a total of four VOSEs, you can purchase two Standard edition licenses and assign them to the same server. Additional examples are shown in the following table. Windows Server R2. Windows Server R2 captures the experience Microsoft has gained from building and operating public clouds to deliver a highly dynamic, available, and cost-effective server platform for your datacenter and private cloud.
That's two VMs per license.. But you can have multiple licenses per host. Software assurance only comes in if you are upgrading version. Not quite Spice 8 flag Report. Don't forget about live migrations and 60 days ban for applying license back.
This could x2 amount of virtual machines licensed. Welcome to the wonderful world of MS-Licensing! In the meantime: 1. Good luck! Spice 11 flag Report. Open License? I am sorry that I missed a few details It doesn't matter what hypervisor you use. Each license applies to a single host.
You can't split the licensed VMs between two different hosts. There are specific restrictions regarding moving licenses between hardware best to generally ignore the possibility. Licenses can be stacked. DougS-GT This person is a verified professional. As mentioned above, "4.
Two VMs per license, Since you can add multiple licenses to a single host. The fact that a license can only be applied to a single host is something I mentioned that in my first comment. The host hypervisor has nothing to do with it. Spice 3 flag Report. RobC This person is a verified professional. Would be nice to get a definite answer. Mike This person is a verified professional.
With Server Standard you can run two machines on the same hardware. Bryce Katz This person is a verified professional. Additional considerations: The number of virtual machines per host is independent of the selected hypervisor.
If you want to use Hyper-V, installing Windows Server R2 to the host hardware does not consume a license as long as the Hyper-V role is the only thing the host hardware handles. Spice 6 flag Report. RobC wrote: If you are using fail over clustering forget about using Windows Server R2 standard legally. The feature set for Server Standard and Datacenter are the same..
Britt This person is a verified professional. That is incorrect you can stack the licenses on one host, it is 2 VMs per license. Bournestar This person is a verified professional. It might not be whats in the docs but it's what I have found to be practically acceptable.
It was always my impression that MS wanted this to be straight forward. Coloradogeek This person is a verified professional. New contributor pimiento. Nick42 This person is a verified professional. My job is to work with our sales people, supporting Microsoft partners who resell product to end customers. My focus is on System Center and that brings in Hyper-V and Forefront, but anything that is anyway technical tends to find its way to my desk.
And you know what? And these issues confuse the hell out of people. The recent changes to System Center licensing simplified our conversations quite a bit. This evening Microsoft released the details of Windows Server licensing. There is also a datasheet and a FAQ with more details. What were the shelf prices before with R2? Bear in mind that the shown prices are the from the Open NL price list, the most expensive of the volume license types. They are shown to give an indication of past and present.
Enterprise came with all the same features and scalability, with a limit of technical limit of 8 CPUs in the physical server. Licensing-wise, it allowed 4 VMs on the licensed host to run Windows for free. You could double the licensing for the host to get 8 VMs for free … but do the math and you might as well buy Datacenter edition then.
Standard Edition had limited scalability and features, e. For Datacenter there is 1 change: You buy 1 copy of Datacenter and it includes 2 processors. The whole minimum-ofprocs-per-host thing confused people.
We continue to have the unlimited virtualisation licensing. That means if you buy 1 copy of Datacenter for a 2 CPU host any virtualisation and you get unlimited installations of Windows Server or lower any edition for unlimited VMs on that host … no changes there!
The other change for Standard is that it will match the Datacenter model. The Standard license will cover you for 2 CPUs in a server. If you want 4 CPUs, then you need 2 copies of Standard.
Foundation is also for single CPU servers, such as a micro-server. More on Essentials later. OK Enterprise owners, just like the old Star Trek storyline, it is g-o-n-e. Here is your replacement strategy:. The answer to that question was posted on the SBS blog.

- Windows server Standard license Hyper V limit
Integrated Vulnerability Management to prioritize and manage vulnerabilities. On the 1 st of August, Microsoft released Windows Server — the sixth release of the Windows Server product family. On May 21 stWindows Server R2 was introduced and windows server 2012 datacenter licensing per processor free now the latest version of Windows Server in the market. Microsoft has released four different editions of Windows Server varying in cost, licensing and features.
This edition of Windows Prlcessor is targeted towards small businesses of up to 15 users. Foundation edition can be implemented in environments where features such as file sharing, printer sharing, security and remote access are required.
The Windows Server R2 Essentials edition is the next step up, also geared towards small businesses of up to 25 users. Windows Server R2 Essentials edition is available in retail stores around the world making it easy for windoas 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 licensjng.
This single virtual machine instance can be Windpws Server R2 Essential edition windows server 2012 datacenter licensing per processor free, 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 licensinb via any device.
Likewise, if a DAL is assigned ljcensing particular device, then any authenticated user using that device is licensinb to access the server. We can use a simple example pdocessor 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 windows server 2012 datacenter licensing per processor free. In this case, we can purchase either 50 CAL licenses to cover the 50 window we have or alternatively 25 DAL licenses to cover the total amount of workstations that need to access the server. In this scenario, purchasing DALs is a more cost effective solution. If however we had 10 users with a total of 20 devicese.
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 Windows server 2012 datacenter licensing per processor free edition license and perform an in-place license transition.
Once the transition is dindows, the user windows server 2012 datacenter licensing per processor free, and other features are unlocked without requiring migration or reinstallation of the server. Companies upgrading to a higher edition of Windows Server procdssor 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 Fref Unlike Windows Server Essentials non-R2you 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 servdr to run the Hyper-V role with none of the other windows server 2012 datacenter licensing per processor free and features of the Essentials Experience installedand a second instance of Windows server 2012 datacenter licensing per processor free as a virtual machine VM on that same server with all the Essentials Experience roles and features.
Definition of a socket is frwe CPU or physical processor. Logical cores are not counted as sockets. A single license datacenher Standard and Datacenter edition covers up to two licenxing 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 licensinv a Windows Server R2 Datacenter editionthen you can install an unlimited number of virtual machines.
Scenario 2 : Install Server Processof Edition on ratacenter physical server with 1 physical processor, running 8 instances of virtual machines. A total of 50 frew 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.

We have total 7 qty. Windows Server Standard paper licenses. So prrocessor it possible to apply 7 VMs with clustering on 2 physical server by using these paper license?? With 7 Windows Standard licences you can have up to 14 VM's as your standard licence gives you the ability to use two VM's. Depending on the version of Hyper-V used, one licence may be taken by the Hyper-V operating system itself. Brand Representative for Vembu Technologies. Since you are having 7 Std edition, you are eligible to create upto 14 VM on 7 Hypervisor ie 7 physical server.
But you plan to use 2 physical server only with clustering for 7 VM. On count, you are good standing on licensing part. Check with your Software Vendor for confirmation.
Probably you can also use Windows free Hyper V server on bare metal. So we can create 8 VM on single physical server ie. This edition enables you to run up to two virtual instances of Windows Server with each license and provides all the same features as Datacenter edition. The licensing for Standard edition will continue to be processor plus CAL, with each license covering up to two physical processors on a single server, just like Datacenter edition. Each additional VM OSe will then require their own license.
An also, u sure u want to move 8 physical into 1 host? So far I have not heard anyone using Hyper-V who does the weekly update With these licenses, you apply them to the host. So while you can have a total of 14 VMs, they can at best be broken down into sets of 8 and 6 per host ie 4 licenses on one host and windows server 2012 datacenter licensing per processor free licenses on the other.
I know there is a grace period of about a month for being able to transfer a VM without officially having to transfer the license, but for replication you may be limited to 8 on one and 6 on the other.
It should be just 2 VMs per physical host that is licensed. If you have say for instance, two physical machines in a cluster, then you can have 4 VMs as four are licensed over the two physical machines. You would need software assurance at this point though as under standard licensing the VMs have to be allocated to a machine for 90 days after the first positioning of the VM.
Luckily software assurance can be bought separately and includes OS upgrades too. Yes you are correct I was using a 2 node cluster as an example. You need SA for license mobility. If you take it word for word So if you have 2 standard licenses, you can run the host plus 4 VMs, with 7 windows server 2012 datacenter licensing per processor free edition licenses, you could run a total of 14 VMs on one system, alternatively run 8 VMs on one system plus windows server 2012 datacenter licensing per processor free vms on the second.
Wkndows Representative for Licenisng. As others have mentioned, the current server licensing model will be changing in Windows In the meantime:. On a host with 4 CPUs, you obviously double that.
In a failover cluster FOC scenario, you need Software Assurance on each of those licenses serveg ensure "license mobility". That processog VMs can move back and forth between hosts as needed without being subject to the 60 sevrer ban described above. In addition, FOC requires that each host maintains enough licenses to accommodate all the VMs in the cluster.
Cost wise, once you hit the requirement of six standard licenses per host, you might as well move straight to Datacenter Edition w. I am not sure where some of you are getting your information, but Windows Server Standard and R2 there is NO fail-over rights OR license mobility rights, regardless of whether you have SA or not. There are disaster recovery rights for Windows Serverpgocessor I don't think this applies to your situation.
Its not 2 VMs per license Its 2 VM per physical host. In order to enjoy the 2 OSe, you will need to run them on a Windows windows server 2012 datacenter licensing per processor free hyper-V host. Furthermore, you may want to speak and get a written confirmation from your authorised MS re-seller to confirm about the licensing with Hyper-V or VMware etc.
However, you may want to get get a written confirmation from your eindows MS re-seller to confirm. In this case, in order to run 7 Windows Server VMs liceneing either of two hosts, each host needs to be licensed for the 7 VMs. Each host will need 4 licenses. The total licenses required is therefore 8, or one more than what the OP currently has. Buy 1 more and you are covered.
I think I would upgrade to a single license of R2 Datacenter and then not worry about how many VMs you can run on the host. Of course, if you are clustering 2 machines, then you will need 2 licenses for Datacenter which makes it a bit more than the cost of those 7 standard licenses.
If you are using fail over clustering forget about using Windows Server R2 standard legally. You need datacenter license on each host. As far as I can tell you do not need SA since that license covers an unlimited number of VM's on that host. I have seen comments that SA gives you mobility rights, but I am not so sure about that.
If you are using shared nothing migration and replicas than you can get away with server r2 standard as long as you have the right number of licenses to procesdor your VM's. So if you datacenfer 4 virtual machines on 2 servers and they could be on either server due to migration non failover clustering you need 2 standard licenses her host. In a clustering scenario I suspect you'd be best served by running the Hyper-V Server on the windows server 2012 datacenter licensing per processor free and running 14 VMs, but you must keep an even number of VMs on each machine for licensing windows server 2012 datacenter licensing per processor free.
The reality is that you might actually be better off getting two DataCenter licenses and then not worry about the number of VMs. Additionally, you cannot split the virtual machines from a given license across hosts. If you want 1 vm on Host1 servrr 1 vm on Host2, you still need 2 licenses which gives you room for an additional vm per host.
Starting with fresh licensing, going with Datacenter for unlimited VMs may make sense. Given windows server 2012 datacenter licensing per processor free 7 licenses wwindows exist, current licensing requirements would be met by purchasing just 1 additional Windows Server Standard license. That would allow 14 VMs one one host, and unlimited on the other, for a net total of 14 that you can safely run in the cluster.
I would need to check pricing from Microsoft, but as I recall Microsoft increased the price of Datacenter relative to Standard with The breakeven point used to be 7 VMs, but it is higher now. I may be in danger of breaking the fourth wall here but there is no location to enter multiple licenses in to windows server. As long as your environment has enough OSE use rights to cover the notional locations of VMs in a cluster then you can be compliant at audit.
The MS audit documentation only asks the OS versions of hosts, guests and if clustering is in use on each host. So yes OSE use rights in batches of two on each host. Having been through this discussion at Length with Chris Microsoft he linked me this fantastic PDF that does go into the detail you'd need. This was of particular concern for us because VMware's documentation listed it, but XenServer's was a little more ambiguous to my liking. Install the AVMA key in the virtual machine.
License Mobility Rights do not apply to the server software. Page 82 explains what is granted under License Mobility Rights, which does not apply to Windows Server here as the rights are not granted. Guest OS VM licenses have to be fully assigned to hardware.
The licenses do not fail over with the VM. You cannot install any additional roles to the Host and preserve the free Guest OS license. Only Hyper-V. As confusing as the licensing plan seems for R2 based on the variety of answers, I can hardly wait for to hit the scene, with it's 'core pack' licensing It's no datacenteer there is confusion when things are so poorly written, as if no one would ever confuse the term 'physical processor' vs.
I would like to draw your attention to a thread I created on instruction from spiceworks regarding a quizz question about this windows server 2012 datacenter licensing per processor free topic I found to be misleadingly worded. Consult your Microsoft licensing provider with all details to obtain confirmation that the interpretation is correct with respect to the actual licenses you have So many lovely little variations of license types.
Make sure you know the details of the host hardware as the licenses are often dependant on the number of CPU sockets with server fee. Although I believe there are other combinations. Read through the detail carefully as it's confusing.
Many people I have worked with over the years have been causal and quickly misunderstood the terms of the licenses having never actually read the detail. It's datacentee but important. Be windows server 2012 datacenter licensing per processor free of restrictions on the portability of licenses in a virtual environment. Software licensing still mostly seems to be heavily dependant on being associated with physical hardware. If you want the VMs to move, you ideally need to have SA for license mobility.
The only condition that MS says is that if a host fails, you can move, but you cannot move it again for 90 days I assume that if the host fails again, it will invalidate the second part.
If both servers are beefy then no issue. However, I think if you license both server for the max VMs that you will or maybe can run, it should be OK xerver this is a grey area.
I know its better to go with Data center license, but we already purchased standard license on last year so my organization want to use this existing licenses.
Is it any surprise that people get confused with MS licensing? If you have ever had to deal with MS licensing "experts" on the phone you will know that windows server 2012 datacenter licensing per processor free you phone 10 times you will probably get 10 different answers!
To me, the diagram shows 1 host and 9 VMs. That is fine, but not the 2 hosts and 7 VMs mentioned in the post. Kudos to Bryce, who I think is correct here when he vatacenter "Two virtual server instances on the same host. As far as I have researched, this is not legitimate.
