Search Enhancements
Indexing service extracts the information from a set of documents and organizes it in a way that makes it quick and easy to access that information through the search function for computers running Windows 2000 or Windows XP.

Efficient Storage Management
Windows Storage Server 2003 R2 includes new tools designed to provide a centralized view of storage; simplified storage planning, provisioning and maintenance; and improved monitoring and reporting. These benefits enable administrators to more efficiently manage storage across IT resources and optimize storage space on those resources.

Distributed File System
The Distributed File System (DFS) solution in Windows Storage Server 2003 R2 helps administrators make files available to more users on a number of distributed servers without increasing administrative complexity. DFS replication uses a new compression algorithm known as Remote Differential Compression (RDC). RDC is a WAN-enabled compression technology that efficiently updates files over limited bandwidth networks by replicating only the changes needed to ensure global file consistency.

Predictable and Easy to Adopt
Windows Storage Server 2003 R2 was built on the efficient, reliable code base of the Windows Server 2003 family. Since it shares the same code base, there is no need for separate application compatibility testing, as all storage applications tested for Windows Server 2003 will function with Windows Storage Server 2003 R2. Plus, antivirus and backup applications that work with Windows Server 2003 operating systems will work with Windows Storage Server 2003 R2.
