Windows Server R2 will continue to have the same licensing model as Windows Server , with two editions available in volume licensing: Standard edition and Datacenter edition. Editions are differentiated by virtualization rights only (two OSEs for Standard, and unlimited OSEs for Datacenter). A single license covers up to two physical. Fellow Techies– I have a LENOVO x X6/x64 based Windows server with 4 18 cores/36 logical processors– with installed physical memory (ram) @ TB, total virtual memory @ TB. However, I am showing only GB of available physical memory and only GB of available virtual memory. The Windows Server R2 Foundationedition comes pre-installed on hardware server with single physical processor and up to 32GB of DRAM memory. Foundation edition can be implemented in environments where features such as file sharing, printer sharing, security and remote access are required.
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.
