Windows Server 2008 R2 (aka win7 server)

[nekrosoft13]

Windows Server 2008 R2 is capable of unprecedented workload size, dynamic scalability, and across-the-board availability and reliability. A host of new and updated features will be available, including leveraging sophisticated CPU architectures, increased operating system componentization, and improved performance and scalability for applications and services.

Windows Server 2008 R2 is the first Windows operating system to be offered for only 64-bit processors. And Windows Server 2008 R2 can now support up to 256 logical processor cores for a single operating system instance, including enhancements in Hyper-V virtual machines which are able to address up to 32 logical cores in a single VM. These improvements not only guarantee more bang for your server hardware buck, but also offer better reliability with fewer locks and greater parallelism.
