5 File server management
This chapter begins by identifying new or improved fi le services in Windows Storage Server 2003 R2. The
remainder of the chapter describes the many tasks and utilities that play a role in fi le server management.
New or improved fi le services features in Windows Storage
Server 2003 R2
Distributed File System
The Distributed File System (DFS) solution in Windows Storage Server R2 provides simpli fi ed, fault-tolerant
access to fi les and WAN-friendly replication. DFS consists of two technologies:
• DFS Namespaces, formerly known as Distributed File System, allows administrators to group
shared folders located on different servers and present them to users as a virtual tree of folders
known as a namespace. A namespace provides numerous bene fi ts, including increased
availability of data, load sharing, and simpli fi ed data migration.
• DFS Replication, the successor to File Replication Service (FRS), is a new state-based, multi-master
replication engine that supports scheduling and bandwidth throttling. DFS Replication uses a new
compression algorithm known as Remote Differential Compression (RDC). RDC is a “diff over
the wire” protocol that can be used to ef fi ciently update fi les over a limited-bandwidth network.
RDC detects insertions, removals, and rearrangements of data in fi les, enabling DFS Replication
to replicate only the deltas (changes) when fi les are updated.
The HP Storage Server Management Console provides access to DFS management tasks.
