DFS Configuration
This section describes which of the DFS components run on the different types of DFS machines - DFS client machines, DFS file server machines, and other DFS server machines.
The cache manager runs on every machine that acts as a DFS client. It communicates with file server machines to provide DFS service. (See the following figure.)
DFS Client and File Server Machines
Several processes run on DFS file server machines: the file exporter (which includes the token manager), the basic overseer server, the replication server, the fileset server, and the client side of the update server. Also present on the file server machine is a physical file system, DCE LFS, UFS, or both.
Some DFS processes must run on a machine that contains the files or database they access. These processes usually run on DFS file server machines. (See the following figure.)
Other DFS Servers
These processes are the server side of the update server (which runs both on machines that contain master copies of configuration files and on machines that contain master copies of binary files), the fileset location server (which runs on machines on which the fileset location database is located), and the backup server (which runs on machines on which the backup database resides).
