Windows Server 2003 R2 Enterprise Edition x64 SP2, 25 Clients
Until recently, the vast majority of servers shipped worldwide were 32-bit servers based on the x86 instruction set. IT professionals have widely deployed 32-bit Windows on these servers for its ease of use, broad functionality, and exceptional value. Today, most new x86-based servers belong to a new class dubbed "x64." These servers carry the same familiar x86 instruction set but with added 64-bit functionality. This means that they can run existing 32-bit software, in addition to new 64-bit software.
<b>Mainstream 64-Bit Computing</b>
While Windows for Itanium is focused on meeting the needs of customers deploying large-scale databases and line-of-business applications, the x64 versions of Windows are designed for all workloads across a broad range of scenarios. For this reason, Microsoft offers three versions of Windows Server 2003 x64 Editions:
• Windows Server 2003, Standard x64 Edition
• Windows Server 2003, Enterprise x64 Edition
• Windows Server 2003, Datacenter x64 Edition
<b>Maximum Flexibility</b>
Windows Server 2003 x64 Editions are designed for the new class of industry-standard x64 hardware. By running both 32-bit and 64-bit software at peak performance, this new platform will extend our customers' current investment in Windows-based technology. x64-based systems give IT professionals the option of running 32-bit Windows today, while moving to 64-bit Windows at their own pace. Once they have deployed the x64 versions of Windows, they can combine 32-bit and 64-bit software on the same system. Providing multiple paths to 64-bit computing maximizes flexibility and eases migration to this new architecture, as illustrated below.
<b>Compatibility and Performance</b>
Early benchmark results show that Windows Server 2003 x64 Editions live up to the promise of running both 32-bit and 64-bit software at high speed. Consider the February 2005 SAP Sales and Distribution Two-Tier benchmark results that combine x64 versions of Windows and SAP R/3 with the 32-bit version of SQL Server 2000 Service Pack 4. In these tests, Windows Server 2003 x64 Editions posted the fastest scores among all 2-way servers, and the second-fastest score among all 4-way servers.
Over time, we believe our customers will increasingly choose the x64 versions of Windows instead of the 32-bit versions for the majority of their computing needs. With support for both x64 and Itanium processors, the 64-bit versions of Windows Server 2003 span the full range of needs for today's IT infrastructure.
