Operating System Features
Distributed File System (DFS)
The Distributed File System (DFS) solution in Windows Storage Server 2003
R2 x64 Edition with SP2 provides simplified, fault-tolerant access to files and
Wide Area Network-friendly replication. Distributed File System consists of
two technologies:
• DFS Namespaces — DFS Namespaces allows administrators to group
shared folders located on different servers and present them to users as a
virtual tree of folders called 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), DFS
Replication is a new state-based, multimaster replication engine that
supports scheduling and bandwidth throttling. DFS Replication uses a
new compression algorithm called Remote Differential Compression
(RDC). RDC is a protocol that can be used to efficiently update files over
a limited-bandwidth network. RDC detects insertions, removals, and
rearrangement of data in files, enabling DFS Replication to replicate only
the deltas (changes) when files are updated.
Storage Management for SANs
Storage Manager for SANs is an MMC snap-in that helps you create and manage
logical unit numbers (LUNs) on Fibre Channel and iSCSI disk drive
subsystems in your SAN. Storage Manager for SANs can be used on storage
subsystems that support Virtual Disk Service (VDS).
Use Storage Manager for SANs to create and assign LUNs, manage
connections between the LUNs and the servers in your SAN, and set the
security properties for iSCSI storage subsystems.
Indexing Service
Indexing Service extracts information from a set of documents and organizes
the information for quick and easy access by the search function for systems
running Windows 2000, Windows XP, or Windows Storage Server 2003 with
SP2. This information can include the document’s contents, characteristics,
and parameters such as the author's name. When the index is created, you can
query the index for documents that contain key words, phrases, or properties.
