About Windows Server 2008 R2
Microsoft's Windows Server 2008 R2 has been around since late 2009, and is built on Windows Server 2008, with a range of new features and enhanced technologies.
The software is available in seven editions, starting with Foundation and including Enterprise, Datacenter and Web. The improved and new features of Windows Server 2008 R2 are Live Migration, which allows applications to be moved between computers without disconnecting them or the program, and Failover Clustering, permitting a number of idle computers to run server applications and thereby reducing the risks of crashes impacting an organisation.
Among the other new features of Windows Server 2008 R2 is Hyper-V, which allows for platform visualisation. The software enables a reduction in power consumption over the previous version, and security has been increased on a number of levels. The system allows for a maximum of 64 physical processors to be supported, and overall there's a marked improvement in performance.
The minimum system requirements to run Windows Server 2008 R2 are a 1.4 GHz (x64) processor or an Intel Itanium 2 processor if operating an Itanium system; 512 MB of RAM, although 2 GB is recommended for optimal performance; and at least 32 GB of space on the hard drive.
In addition, Windows Server 2008 R2 requires Super VGA display in 800 x 600 or higher resolution and the usual peripherals such as DVD drive, internet access for updates and to activate the product online. A Microsoft product key will unlock the full version of Windows Server 2008 R2.
