Microsoft Windows Server 2003 Enterprise Edition for 64-bit Itanium-based Systems - 1 server, 25 clients
Windows Server 2003 x64 editions provide high performance for both 32-bit and 64-bit applications on the same system. The underlying architecture is based on 64-bit extensions to the industry-standard x86 instruction set, allowing today's 32-bit applications to run natively on x64 processors. At the same time, new 64-bit applications are executed in 64-bit mode, which processes more data per clock cycle, allows direct access to more physical memory (RAM), and speeds numeric calculations. The end result is a platform that leverages the existing wealth of 32-bit applications while also providing a smooth migration path to 64-bit computing.
The Windows Server x64 editions are compiled from the same codebase as the 32-bit version. This makes the x64 editions a mature, reliable platform, naturally suited to inherit most of your 32-bit solutions as you replace older servers with today's x64 hardware. Furthermore, the Windows Server x64 editions provide the power and scalability needed to virtualize or otherwise consolidate server workloads.
The best way to take full advantage of today's x64 server hardware is with a solution built on a Windows Server x64 edition.
Benefits of Microsoft Windows x64 Editions
This white paper examines the benefits of x64 architecture running on Microsoft Windows Server 2003 x64 Editions and Microsoft Windows XP Professional x64 Edition. These benefits include a larger virtual memory-address space, support for larger physical RAM, improved performance and reliability, enhanced security, and an unprecedented level of compatibility. With the release of the x64 Editions of Windows, 64-bit computing is poised to become the mainstream of personal and corporate computing
