System Requirements Actual requirements will vary based on your system configuration and the applications and features you choose to install. Processor performance is dependent upon not only the clock frequency of the processor, but also on the number of cores and the size of the processor cache. Disk space requirements for the system partition are approximate. Itanium will vary from these disk size estimates. Additional available hard-disk space may be required if you are installing over a network. For more information, please see www.microsoft.com/windowsserver2008R2. * Note: Computers with more than 16 GB of RAM will require more disk space for paging, hibernation, and dump files
