Cluster
From SambaWiki
A clustered file server ideally has the following properties:
- All clients can connect to any server.
- A server can fail and clients are transparently reconnected to another server.
- All servers can serve out the same set of files.
- All file changes are immediately seen on all servers (distributed filesystem)
- Ability to scale by adding more servers/disk backend.
- Appears as a single large system.
