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. 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 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.
You have two options to license each host for up to 10 VOSEs. Firstly you could license each of the hosts with 5 copies of Windows Server Standard.
Each host has 2 CPUs, so each host requires 1 copy of Datacenter. There are 2 hosts so we require 2 copies of Windows Server Datacenter. You could add more hosts to this cluster and each could have unlimited VMs. As long as the hosts have 1 or 2 CPUs each, each additional host requires only 1 copy of Windows Server Datacenter to license it for unlimited installs of Windows Server for the VMs on that host. The magic number of 10 VOSEs is a dot in the rear view mirror.
We now have lots of hosts with lots of VMs flying all over the place. Each host has 4 CPUs. Live Migration Outside the Cluster. If this is an infrequent move then you could avail of the VL 90 day mobility right to reassign a license, ensuring the the old host is sufficiently licensed for remaining VOSEs and physical CPUs. Therefore it is irrelevant in this conversation. Buying another product is just more money spent. 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.
We have hosting facilities for spla customers, but our on-premises clients typically are not paying for spla licenses since they have their own on-premises licenses etc.
So what if we want to offer them Hyper-v replication to our hosting center? What would be possible scenarios for this? A very good question. Until then, it is pure speculation. Very good post. I just have one question. In the 2 server scenario, with shared storage between hosts, each host still needs to be licensed to handle 10 VMs each?
What happens on the 2nd server if not sufficiently licensed? Does an error message popup? 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! Unlike Windows Server Essentials non-R2 , you 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 server to run the Hyper-V role with none of the other roles and features of the Essentials Experience installed , and a second instance of Essentials as a virtual machine VM on that same server with all the Essentials Experience roles and features.
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. The image comes from the original Microsoft PDF document referenced at the bottom of the post.
As you can see, there are 3 physcial hosts. The one on the left has two standard licenses, while the two others do have three standard licenses. You can move VMs from the left to the middle and right hosts, because they have 3 Windows Server licenses assigned 6VMs each maxi.
If they only had two licenses assigned, then you would not be able to do that. I'm also assuming that there are at least 2 physical hosts. You see, we're almost there. The 11th VM will make difference. The Windows Server licensing is cheaper when running more than 10 VMs and taking the Datacenter license.
Again, I'll demonstrate with an image, where you'll see that the requirements to run 10VMs per host must be kept. I'm assuming that during the normal workload five VMs run on each host.
