Microsoft Windows 2003 Enterprise R2 25 CAL Retail Box
Quantity in Basket:
Windows Server 2003 R2 Enterprise Edition differs from Windows Server 2003 R2 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. With Windows Server 2003 R2 Enterprise Edition, organizations can deploy highly available and scalable applications on industry-standard PC hardware. The result is a highly productive infrastructure optimized for running all your business-critical applications and services. For example, Windows Server 2003 R2 Enterprise Edition excels at supporting networking, messaging, inventory and customer service systems; databases; e-commerce Web sites; and file and print servers. For growing organizations, the ability to scale critical applications both up and out allows them to meet changing demands. Regardless of the size of your organization, Windows Server 2003 R2 Enterprise Edition is a good choice for running applications that must be available at all times.
Cluster service. Server clusters provide high availability and disaster tolerance for mission-critical database management, file sharing, intranet data sharing, messaging, and general business applications. With Windows Server 2003 R2 Enterprise Edition, and Windows Server 2003 R2 Datacenter Edition, cluster service supports up to eight-node clusters for increased flexibility in adding and removing hardware in a geographically dispersed cluster environment.
Cross-file remote differential compression (RDC) support. DFS Replication in Windows Server 2003 R2 uses RDC to replicate only the differences (or changes) between the members when a file is changed. This allows branch offices with slow WAN connections to participate in replication using minimal bandwidth. When DFS Replication is deployed on servers running Windows Server 2003, Enterprise or Datacenter Edition, an additional function of RDC known as cross-file RDC is used. Cross-file RDC uses a heuristic to identify files that are similar to the file that needs to be replicated. This is useful when a new file is created on one server and needs to be replicated to another server. Instead of replicating the entire file, DFS Replication can use portions from files that are similar to the replicating file to minimize the amount of data transferred over the WAN.
Metadirectory Services support. Microsoft Metadirectory Services (MMS) helps organizations integrate identity information from multiple directories, databases, and files with Active Directory. MMS provides a unified view of identity information, enables the integration of business processes with MMS, and helps synchronize identity information across an organization.
Hot Add Memory. Hot Add Memory allows ranges of memory to be added to a computer and made available to the operating system and applications as part of the normal memory pool. No rebooting and no downtime are required. This feature currently operates only on servers that have hardware support for adding memory while the server is operating. For these servers, the act of installing memory automatically invokes the Hot Add Memory feature in Windows Server 2003 R2 Enterprise Edition.
Non-Uniform Memory Access (NUMA). System firmware can create a table called the Static Resource Affinity Table that describes the NUMA topology of the system. Windows Server 2003 R2 Enterprise Edition uses this table to apply NUMA awareness to application processes, thread default affinity settings, thread scheduling, and memory management features. Additionally, the topology information is made available to applications using a set of NUMA application programming interfaces.
Terminal Services session directory. This load balancing feature allows users to reconnect easily to a disconnected session on a server farm running Terminal Services. Session directory is compatible with the Windows Server 2003 load balancing service and is supported by third-party external load balancer products.
Windows System Resource Manager. A feature in both Windows Server 2003 R2 Enterprise Edition, and Windows Server 2003 R2 Datacenter Edition, the Windows System Resource Manager (WSRM) enables an administrator to allocate CPU and memory utilization on a per-application basis. This is a useful tool for server consolidation.

Windows Server 2003 is a surprisingly full-featured release, but because it builds on the strong base of Windows 2000 Server, it will be a simple in-place upgrade for those customers. Thanks to its new upgrade features, it should also prove to be a simpler upgrade for the large crowd of NT 4.0 Server holdouts, though we'll have to test that functionality before passing final judgment.
