Question 1 - Why does Windows Server 2008 come in different versions? What is the significance of each version?
Most editions of Windows Server 2008 are available in x86-64 and IA-32 versions. Windows Server 2008 for Itanium-based Systems supports IA-64 processors. Microsoft has optimized the IA-64 version for high-workload scenarios like database servers and Line of Business (LOB) applications. As such it is not optimized for use as a file server or media server. Microsoft has announced that Windows Server 2008 is the last 32-bit Windows server operating system. Windows Server 2008 is available in the editions listed below, similar to Windows Server 2003.
• Windows Server 2008 Standard (IA-32 and x86-64)
Windows Server 2008 Standard is one of Microsoft's entry level server offerings (alongside Windows Web Server 2008) and is one of the least expensive of the various editions available. Both 32-bit and 64-bit versions are available, and in terms of hardware Standard Edition supports up to 4GB of RAM and 4 processors.
Windows Server 2008 is primarily targeted and small and mid-sized businesses (SMBs) and is ideal for providing domain, web, DNS, remote access, print, file and application services. Support for clustering, however, is notably absent from this edition.
An upgrade path to Windows Server 2008 Standard is available from Windows 2000 Server and Windows Server 2003 Standard Edition. • Windows Server 2008 Enterprise (IA-32 and x86-64)
Windows Server 2008 Enterprise Edition provides greater functionality and scalability than the Standard Edition. As with Standard Edition both 32-bit and 64-bit versions are available. Enhancements include support for as many as 8 processors and up to 64GB of RAM on 32-bit systems and 2TB of RAM on 64-bit systems.
Additional features of the Enterprise edition include support for clusters of up to 8 nodes and Active Directory Federated Services (AD FS).
Windows Server 2000, Windows 2000 Advanced Server, Windows Server 2003 Standard Edition and Windows Server 2003 Enterprise Edition may all be upgraded to Windows Server 2008 Enterprise Edition. • Windows Server 2008 Datacenter (IA-32 and x86-64)
The Datacenter edition represents the top end of the Windows Server 2008 product range and is targeted at mission critical enterprises requiring stability and high uptime levels. Windows Server 2008 Datacenter edition is tied closely to the underlying hardware through the implementation of custom Hardware Abstraction Layers (HAL). As such, it is currently only possible to obtain Datacenter edition as part of a hardware purchase.
As with other versions, the Datacenter edition is available in 32-bit and 64-bit versions and supports 64GB of RAM on 32-bit systems and up to 2TB of RAM on 64-bit systems. In addition, this edition supports a minimum of 8 processors up to a maximum of 64.
Upgrade paths to Windows Server 2008 Datacenter Edition are available from the Datacenter editions of Windows 2000 and 2003.
