The AndrewFileSystem:
* was developed as part of the AndrewProject
* is a NetworkFileSystem
* uses full ACLs rather than traditional Unix permissions - see [AFSACLs]
* supports replication of the filebase across multiple servers for [Reliability] and [Availability]
* uses [Kerberos] for Authentication ([Kerberos5] prefered, though [Kerberos] 4 is native to OpenAFS)
* uses "tokens" tied to your UID to your [PAG], which are [Kerberos] 4 tickets stuffed into the kernel
* can cache files locally for fast access even to files only available to you over a slow link
* was originally called "Vice" (the Andrew Toolkit was known as 'Virtue')
* no longer copies the entire file when it's opened for writing, which is slow for large files

The [AFS] team went on to develop [Coda] as a research project on DisconnectedOperation, which spun off [Intermezzo], which in turn spun off [Lustre].

[AFS] however has not been abandoned and continues to thrive, offering gigantic scaling capacities.

There is [OpenAFS] support in [Kernel] 2.6.7.
