OpenAFS is an open source implementation of the AFS distributed file system. OpenAFS has clients for most UNIX platforms, Windows, and Mac OS X, and an AFS client also exists for iOS. AFS is a Kerberos-authenticated distributed file system that uses Kerberos for authentication and supports client-transparent location independence and client-side caching.
AFS is a cross-platform distributed file system with clients for most versions of UNIX, Windows, Mac OS X, and iOS devices. It uses Kerberos for authentication and supports several interesting features that are not common in other distributed file systems: full client-transparent location independence of files (admins can move AFS volumes from one file server to another with no user-visible downtime), extensive client-side caching, a uniform world-wide namespace, and good performance on long-distance network links.
It is primarily used in universities, large corporations (particularly Wall Street financial firms), and the high-energy physics community.
OpenAFS is the most common implementation. It is the open-sourced version of the original AFS code developed first at CMU and then by Transarc (later acquired by IBM).
