Overview

This edition is well-suited for high-performance computing clusters, Active Directory data stores larger than 2 GB, Terminal Server deployments, and memory-bound applications that do not require more than four processors. Microsoft Windows Server 2003 R2 Standard Edition helps you increase the effectiveness of your computing operation while reducing IT costs. New features simplify and improve branch server management, storage management, and identity and access management, while taking advantage of x64 technology.

Your business can realize a number of benefits from x64 technology—from the ability to scale servers to fit your needs to improved performance and security. With Windows Server x64 editions, you can experience the power of 64-bit processing while maintaining compatibility with your existing 32-bit applications.

Main Features

• Scalability. The most scalable Windows servers available are based on 64-bit technologies. The x64 technologies provide scalable solutions that allow server consolidation and virtualization, and help reduce operating expenses and total cost of ownership (TCO).
• Security. Features such as Data Execution Prevention (DEP) and PatchGuard improve security by helping to prevent malicious code from executing on a server.
• Reliability. Based on the same code base as Windows Server 32-bit editions, the Windows Server x64 editions offer the time-tested reliability of the Windows Server platform while providing a platform for both your new, high-performance native x64 applications and the legacy 32-bit applications that are still critical today.
• No Price Premium for x64 Performance. The vast majority of new servers sold today contain x64 processors—only a few are available with 32-bit processors. Windows Server x64 editions are priced and licensed identically to their 32-bit counterparts. The best way to take full advantage of your new server hardware—at no additional cost—is to deploy servers with Windows Server x64 editions.
• Compatibility. Unlike other 64-bit platforms, such as those based on Intel’s Itanium architecture, x64 systems can run 32-bit applications without emulation, resulting in comparable performance on 32-bit and 64-bit systems. This key benefit allows you to transition to x64 applications at a pace that makes sense for your own organization.
• Access More Physical Memory. Native x64 applications, combined with Windows Server x64 editions and suitable server hardware can access up to 2 terabytes (TB) of physical RAM, empowering today’s most demanding server applications.
• Relieve Virtual Address Limitations. On 32-bit systems, connection-oriented applications require the operating system kernel to utilize a portion of its 2-gigabyte (GB) memory space. As applications such as terminal server scale to support more users, this memory allocation can become a bottleneck regardless of the system’s physical RAM capacity. Windows Server x64 editions provide an 8-TB virtual address space for the kernel, and for each process on the system.
• Improved Performance. While 32-bit applications perform similarly on Windows Server 32-bit editions and Windows Server x64 editions, native x64 applications can see significant performance improvements, particularly for computationally intensive applications.
• Data Execution Prevention. Windows Server x64 can help prevent buffer overflow exploits with Data Execution Prevention. Whether via software or the hardware support of AMD and Intel processors, memory that is used for data can be marked as data, preventing it from being treated as executable code, thus helping to prevent such exploits.
• PatchGuard. Windows Server x64 editions support PatchGuard technology, which prevents third-party programs from patching the Windows kernel. This can help improve security by helping to eliminate rootkits and other potentially damaging software.
