Configuring windows 2012 DFS
The Distributed File System (DFS) technologies offer wide area network (WAN)-friendly replication as well as simplified, highly available access to geographically dispersed files.The Distributed File System role service consists of two child role services:
• DFS Namespaces
• DFS Replication
DFS offers the following benefits:
Shared folders on a network appear in one hierarchy of folders created by a DFS Root with links. This simplifies user access.
Fault tolerance is an option by replicating shared folders. Uses the Microsoft File Replication Service (FRS).
Load balancing can be performed by distributing folder access across several servers.
There are two DFS models as follows:
No Active Directory implementation
Can implement load balancing, but replication of shares is manual
DFS Root cannot be replicated
DFS accessed by \\Server_Name.Domain_Name\DFS_Root_Name
Choose a stand-alone namespace if any of the following conditions apply to your environment:
• Your organization does not use Active Directory Domain Services (AD DS).
• You need to create a single namespace with more than 5,000 DFS folders in a domain that does not meet the requirements for a domain-based namespace (Windows Server 2008 mode).
• You want to increase the availability of the namespace by using a failover cluster.
Available only to members of a domain
Can implement fault tolerance by Root and Link replication and load balancing, and replication of links and root is automatic
DFS accessed by \\Domain_Name\DFS_Root_Name
Choose a domain-based namespace if any of the following conditions apply to your environment:
• You want to ensure the availability of the namespace by using multiple namespace servers.
• You want to hide the name of the namespace server from users. Choosing a domain-based namespace makes it easier to replace the namespace server or migrate the namespace to another server.
The DFS root (a table of contents)
Main container that holds links to shared folders
Folders from all domain computers appear as if they reside in one main folder
DFS links (pointers to shares)
Designated access path between the DFS root and shared folders
Replica sets (targets (duplicated shares))
Set of shared folders that is replicated to one or more servers in a domain
