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.

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 Essentials will support up to 25 users and 50 devices. The idea behind Essentials is that it will be the successor to SBS. Transitioning legacy HP systems to mission-critical.

Oct 14, · Prior to , it supported 4, and then the licensing changed with so that Standard would be sold per processor (socket) with a maximum of two. Technically, the binaries are the same for Standard and Datacenter, so you can most likely get it to run with more somehow, but it is not a supported configuration.

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 the 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 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. Windows Server R2 product page.

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 3 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 standard edition licenses, you could run a total of 14 VMs on one system, alternatively run 8 VMs on one system plus 6 vms on the second. Brand Representative for StarWind. 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 to ensure "license mobility". That means VMs can move back and forth between hosts as needed without being subject to the 60 day 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 Server , but 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 server 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 authorised MS re-seller to confirm. In this case, in order to run 7 Windows Server VMs on 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 cover your VM's. So if you have 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 hardware and running 14 VMs, but you must keep an even number of VMs on each machine for licensing purposes.
The reality is that you might actually be better off getting two DataCenter licenses and then not worry about the number of VMs. 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.
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.
