- AFS is a distributed file system which joins together the file systems of multiple file server machines. "AFS makes it easy for people to work together on the same files, no matter where the files are located. AFS users do not have to know which machine is storing a file, and administrators can move files from machine to machine without interrupting user access. Users always identify a file by the same pathname and AFS finds the correct file automatically, just as happens in the local file system on a single machine."
- OpenGFS is a journaled filesystem that supports simultaneous sharing of a common storage device by multiple computer nodes. This is one way to implement a "clustered file system".
