Distributed File System
The Distributed File System (DFS) solution in Windows Storage Server R2 provides simplified, fault-tolerant
access to files and WA N-friendly replication. D FS 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 benefits, including increased
availability of data, load sharing, and simplified 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 efficiently update files over a limited-bandwidth network.
RDC detects insertions, removals, and rearrangements of data in files, enabling DFS Replication
to replicate only the deltas (changes) when files are updated.
The HP Storage Server Management Console provides access to DFS management tasks.
