• Uses tokens to ensure that users are working with the most-recent copy of a file
and to track who is working on the file
• Allows administrators to replicate commonly used DCE LFS filesets on multiple
File Server machines
• Allows easier recovery from severe system failures
• Provides increased availability of files through replication and caching
• Improves load balancing of data
• Tracks the location of every fileset
• Extends the UNIX permissions to provide more precise definitions of access
permissions for directories and files using ACLs
• Allows the use of data from non-LFS file systems
• Allows the addition of server and client machines to an
HP DCE/9000 DFS
configurationwith little impacton other servers or clientsandwith few additional
administrative responsibilities
• Supports enhanced administration and security
• Stores central copies of system configuration and binary files on designated
machines and distributes these files to other server machines in the network
