Create LUN Wizard
Use the Create LUN Wizard to create a LUN (logical unit), which is used to allocate space on a storage
array. You can assign a ser ver to the LUN as you create it, or wait until you are ready to deploy the LUN.
Distributed File System
The Distributed File System (DFS) solution in Windows Storage Ser ver R2 provides s implified, fault-tolerant
access to files and WAN-friendly replication. DFS consists of two technologies:
• DFS N amespaces, 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 n
amespace. A namespace provides numerous benefits, including increased
availabil
ity 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 s upports scheduling and bandwidth throttling. DFS Replication uses a new
compression algorithm known as Remote D ifferential Compression (RDC). RDC is a “diff over
the wire” protocol that can be used to efficiently update files over a limited-bandwidth network.
RDC d ete
cts insertions, removals, and rearrangements of data in files, enabling DFS Replication
to repli
cate on ly the deltas (changes) when files are updated.
The HP Storage Server Management Console provides access to DFS management tasks.
