The Windows Server 2003 R2 family has three member editions, each designed to serve specific and different business needs. The three members are Standard Edition, Enterprise Edition, and Datacenter Edition. We will now look a little more closely at each.
Windows Server 2003 R2 Standard Edition
Windows Server 2003 R2 Standard Edition delivers intelligent file and printer sharing, secure Internet connectivity, centralized desktop policy management, and Web solutions. Designed for small organizations and departmental use, Windows Server 2003 R2 Standard Edition provides high levels of dependability and security.
Windows Server 2003 R2 Standard Edition takes the best of Windows 2000 Server technology and makes it easier to deploy, manage, and use. The result is a highly productive operating system that is secure, reliable, highly available, and scalable.
Windows Server 2003 R2 Enterprise Edition
Designed for medium to large businesses, Windows Server 2003 R2 Enterprise Edition excels in supporting application types such as messaging, inventory, customer service systems, databases, and transactional e-commerce Web sites. Windows Server 2003 R2 Enterprise Edition delivers high reliability, performance, and superior business value.
Windows Server 2003 R2 Enterprise Edition differs from Windows Server 2003 Standard Edition, primarily in its support for high performance servers and its ability to cluster servers for greater load handling. These capabilities provide reliability that helps ensure systems remain available—even if problems arise.
Windows Server 2003 R2 Datacenter Edition
Microsoft offers Windows 2003 R2 Datacenter Edition to businesses that demand the highest levels of scalability, availability, and reliability. Datacenter Edition meets those demands by being deliberately designed to support mission-critical solutions for databases; enterprise resource planning software; high-volume, real-time transaction processing; and server consolidation. Windows 2003 R2 Datacenter Edition is available through original equipment manufacturer (OEM) partners that sell only fully tested and certified configurations, in accordance with Microsoft’s strict requirements.
In addition to getting support through the usual Microsoft channels, customers of Windows 2003 R2 Datacenter Edition can join the Windows Datacenter High Availability Program.
