Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support. The process of moving to Windows Server R2 might vary greatly depending on which operating system you are starting with and the pathway you take. We use the following terms to distinguish among different actions, any of which could be involved in a new Windows Server R2 deployment.
Installation is the basic concept of getting the new operating system on your hardware. Specifically, a clean installation requires deleting the previous operating system. Upgrade means moving from your existing operating system to Windows Server R2, while staying on the same hardware. Even while staying on the same hardware, some server roles might require specific steps to ensure a smooth upgrade. For detailed information about upgrading by any of these methods to Windows Server R2, see upgrade options.
Migration means moving from your existing operating system to Windows Server R2 by transferring to a different set of hardware. Did you know that Microsoft Azure provides similar functionality in the cloud? Learn more about Microsoft Azure virtualization solutions. Before you start a clean installation of Windows Server R2, you should perform the following steps. The following are estimated system requirements for the Windows Server R2.
If your computer has less than the “minimum” requirements, you will not be able to install this product correctly. Actual requirements will vary based on your system configuration and the applications and features you install. Consult documentation for each of the server roles you intend to deploy for more details about the resource needs of particular server roles. For the best results, conduct test deployments to determine appropriate system requirements for your particular deployment scenarios.
Processor performance depends not only on the clock frequency of the processor, but also on the number of processor cores and the size of the processor cache. The following are the processor requirements for this product:. If you create a virtual machine with the minimum supported hardware parameters 1 processor core and MB RAM and then attempt to install this release on the virtual machine, Setup will fail. To avoid this, do one of the following: Allocate more than MB RAM to the virtual machine you intend to install this release on.
Once Setup has completed, you can change the allocation to as little as MB RAM, depending on the actual server configuration. In the command prompt that opens, use Diskpart. Close the command prompt and proceed with Setup. The following are the estimated minimum disk space requirements for the system partition. Be aware that 32 GB should be considered an absolute minimum value for successful installation.
For the smallest possible installation footprint, start with a Server Core installation and then completely remove any server roles or features you do not need by using Features on Demand. The system partition will need extra space for any of the following circumstances: If you install the system over a network. Computers with more than 16 GB of RAM will require more disk space for paging, hibernation, and dump files. To ensure that you are aware of any issues that might require workarounds, features that have been removed from the product, and features that have been added to the product, review these topics:.
What’s New in Windows Server R2. You can also buy retail versions from the Microsoft Store. Before you install Windows Server R2, follow the steps in this section to prepare for the installation. Disconnect UPS devices. If you have an uninterruptible power supply UPS connected to your destination computer, disconnect the serial cable before running Setup.
Setup automatically attempts to detect devices that are connected to serial ports, and UPS equipment can cause issues with the detection process. Back up your servers. Your backup should include all data and configuration information that is necessary for the computer to function. It is important to perform a backup of configuration information for servers, especially those that provide network infrastructure, such as Dynamic Host Configuration Protocol DHCP servers.
When you perform the backup, be sure to include the boot and system partitions and the system state data. Another way to back up configuration information is to create a backup set for Automated System Recovery. Disable your virus protection software. Virus protection software can interfere with installation. For example, it can make installation much slower by scanning every file that is copied locally to your computer. 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.

Connect and share knowledge within a single location that is structured and easy to search. We are using Windows server standard server with 2. SQL Server is installed in it and also our primary application is installed on the server. The server performance hits badly sometimes when SQL Server holding the entire memory of the server. SQL Server is greedy when it comes to memory usage, and that is by design.
It keeps as much data as it can in RAM because it is faster than having to access disk to fulfill a query or other request. As a result, you may want to set the minimum memory allocation for a SQL Server instance so it doesn’t suffer from what I call memory starvation.
If this happens, the server’s drives will thrash because database usage will require disk accesses. You’ll also want to set the maximum memory allocation as already mentioned. I noticed you said sometimes the performance suffers. Do you have other applications collocated on this server?
Are there SQL Agent tasks scheduled to run at certain times? Backups can take a lot of resources and other applications sharing resources could end up fighting over them with SQL Server.
In that case, you may need to add more memory and carefully tune how it’s used, or move the application to another server. Sign up to join this community. The best answers are voted up and rise to the top. Stack Overflow for Teams — Start collaborating and sharing organizational knowledge.

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. 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 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.
A total of 50 users 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.
