Virtualisation Licensing for WS & WS R2 | Aidan Finn, IT Pro. |
- Windows server 2012 standard maximum cores free
Windows Server is out and the editions available differ somewhat from prior Windows operating system releases. With the editions available, key differences are not regarding features as one might think but actually concern virtualization rights. Both editions support the same amounts of memory, physical processors, and logical processors. This post is for informational purposes only. These two editions детальнее на этой странице all the same features. For example, previous Standard editions did not contain Failover Clustering.
Therefore, to use that feature it required Enterprise or Datacenter. Enterprise edition for Windows Server does not exist. You will find that Failover Clustering as well as any other feature you can find in Windows Server Datacenter also exists with Standard edition. Virtualization and processor licensing are key differentiators.
Therefore, CAL посмотреть больше have not changed. As in the past, CALs must be equivalent or higher in version as compared to the Windows Server version being accessed. What is different is what the Windows Server license provides. A single license for either available edition provides use of up to two physical processors.
If you have additional physical processors in the same server, simply windows server 2012 standard maximum cores free additional licenses for Windows Server узнать больше здесь the edition windows server 2012 standard maximum cores free as needed for the additional set of physical processors.
Currently you can only register one license key per server. Just make certain you have enough licenses purchased to cover the number of physical processors and for any virtualization needs discussed in the next section. Remember, each license provides for up to two additional physical processors.
The number of cores available per processor is irrelevant. For purposes of example, if you assign four Windows Server Standard edition licenses to the same server, that server is licensed for читать статью of eight physical processors and as many cores per physical processor as the OS will support. Standard server licenses provide the ability to host two virtual machines VMs on those same two physical processors that the license covers.
The same license also provides virtualization rights. Using the above example with four Standard edition licenses, the server is licensed for use of eight physical processors, as many cores as the OS supports, and up to eight VMs. If you have a need to support ten VMs on the same four physical processor system, simply assign one more Standard edition license to support ten VMs even though the hardware may only have four physical processors.
The number of licenses needed depends on the number of physical processors or VMs windows server 2012 standard maximum cores free be hosted — whichever number is higher. A Datacenter license provides the ability to host an unlimited number of VMs on those same two physical processors. However, like a Standard edition license, you need to assign additional Datacenter edition licenses based on the number of physical processors needed.
The number of cores per physical processor remains irrelevant other than staying within the bounds of the OS and, of course, what the hardware windows server 2012 standard maximum cores free will support. My take on this is that if you are going to be hosting a serious number of VMs on a host with lots of processors and cores, Datacenter is likely the most cost effective path. Standard Edition may fit some situations.
However, Datacenter is obviously more flexible in terms of virtualization rights and is likely a better fit for highly virtualized environments. While with either edition you may assign more licenses, those licenses have to windows server 2012 standard maximum cores free for the same edition and may not be intermixed.
So what can you do if you go with Standard and find out that the future of the server requires more licensing capacity? You could continue to purchase and assign additional Standard edition licenses as applicable.
If you have Software Assurance benefits, you may be able to purchase a Step-up to migrate to a Datacenter license for that server. Windows Server supports up to 64 physical processors with an upper limit of logical processors. Hyper-V enabled systems have an upper limit of logical processors.
Physical cores remain a preferred option in lieu of logical processors from Simultaneous Multithreading SMT when physical cores are available. My на этой странице behind writing this post were to help communicate a significant change that affects server deployment planning. The cost of licenses for Standard and Datacenter editions are different to account for the licensing changes. The windows server 2012 standard maximum cores free per instance appears to have been reduced such that equivalent instances for Windows Server may be less than Windows Server R2 Enterprise.
Again, this post windows server 2012 standard maximum cores free not a definitive source for what a license covers, what the terms are, or what all the different options are that are available.
