A total of 40 cores must be licensed 20×2. All physical processors need to be licensed. There is no business class way to run windows server 2012 standard maximum cores free on top of Windows, that would require a type 2 hypervisor like VirtualBox which is fine for desktop testing, but not okay for a server. VMs running Windows virtual servers need to be migrated between hosts. Scenario 2 : Install Server Standard Edition on a physical server bing free for windows 1 physical processor, running 8 instances of virtual machines. You can simply buy 20 double-core licenses.

Provide mass storage drivers. If your manufacturer has supplied a separate driver file, save the file to a floppy disk, CD, DVD, or Universal Serial Bus USB flash drive in either the root directory of the media or the amd64 folder. To provide the driver during Setup, on the disk selection page, click Load Driver or press F6.

You can browse to locate the driver or have Setup search the media. Be aware that Windows Firewall is on by default. Server applications that must receive unsolicited inbound connections will fail until you create inbound firewall rules to allow them. Check with your application vendor to determine which ports and protocols are necessary for the application to run correctly. For all editions, you have 10 days to complete online activation, at which point the evaluation period begins and runs for days.

During the evaluation period, a notification on the Desktop displays the days remaining the evaluation period except in Windows Server Essentials. You can also run slmgr. All evaluation versions are fully functional during the evaluation period, although booting to Safe mode is not available. The Windows Server Standard and Windows Server Datacenter editions come with the activation key pre-installed. After the day evaluation period elapses, the server warns you in various ways depending on the edition:.

The operating system will shut down every hour. Windows Server Essentials: you receive warnings on the Desktop and on the dashboard, but the server does not shut down. The resulting virtual machine has the following characteristics:. The Hyper-V server role must be installed. Download the VHD file to a convenient location. Start Hyper-V Manager. On the Action menu, point to New , and then point to Virtual Machine. After completing the New Virtual Machine wizard, check Hyper-V Manager to verify that the virtual machine was successfully created.

Right-click the new virtual machine and point to Settings. In the left pane, click IDE Controller 0. In the right pane, point to Hard Drive , and then Add. In the menu that opens, click Virtual Hard Disk and point to Browse Configure the network adapter for the resulting virtual machine: right-click the virtual machine and select Settings. In the left pane, click Network Adapter. In the menu that appears, select one of the network adapters of the virtualization server, and then click OK.

Enabling this technology reduces the overall size of the system virtual address space and therefore system resource maximums. For more information, see What is 4GT. Limits on physical memory for bit platforms also depend on the Physical Address Extension PAE , which allows bit Windows systems to use more than 4 GB of physical memory. The following table specifies the limits on memory and address space for supported releases of Windows.

Unless otherwise noted, the limits in this table apply to all supported releases. The following table specifies the limits on physical memory for Windows Server Windows Server is available only in X64 editions. The following table specifies the limits on physical memory for Windows Server R2. 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 to 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 itself 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 be 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 thoughts 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 price 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 is not a definitive source for what a license covers, what the terms are, or what all the different options are that are available. You must be a registered user to add a comment.
