The Microsoft Distributed File System, or '''DFS''', is a set of client and server services that allow a large enterprise to organize many distributed SMB file shares into a Distributed File System . DFS provides location transparency and redundancy to improve data availability in the face of failure or heavy load by allowing shares in multiple different locations to be logically grouped under one folder, or DFS root. Microsoft's DFS is referred to interchangeably as 'DFS' and 'Dfs' by Microsoft and is unrelated to the DCE Distributed File System . DETAILS When users try to access a share that exists off the DFS root, the user is really looking at a DFS link and the DFS server transparently redirects them to the correct file server and share. A DFS root can only exist on a Windows 2000 version that is part of the server family, or on Windows Server 2003 . Windows 2000 can only host one DFS root per server, while Windows Server 2003 Enterprise and Datacenter Edition can host multiple DFS roots on the same server. (A Samba server can also host the root of a DFS.) There are two ways of implementing DFS on Windows 2000 and Windows Server 2003:
Enhanced DFS management and RDC (Remote differential compression) are part of the "branch office server management" features added to Windows Server 2003 in the R2 release in 2006 . Versions 2.6 and later of the Linux Kernel come with a SMB client VFS called "cifs" that supports DFS. SEE ALSO |
