What is AFS?
AFS is a distributed filesystem that enables co-operating hosts (clients and servers) to efficiently share filesystem resources across both local and wide area networks. AFS is provided and supported by The OpenAFS Community.
At Stanford, ITSS uses AFS to provide and
maintain a campus-wide distributed filesystem -- the
AFS cell. This cell currently consists of fifteen AFS servers,
geographically distributed across campus, and 3 terabytes of usable
disk space, which is backed up nightly.
Stanford uses this AFS cell to provide home directories for
SUNet ID Accounts, many Stanford classes, student and research groups, many
Stanford University departments and campus organizations. Our AFS cell is
also the home for our
/usr/pubsw campus software service, which
allows AFS client machines (for a variety of supported architectures) to
access and use software compiled and maintained by Infrastructure Services
Over a thousand machines on the Stanford campus run AFS client software,
giving people local access to their SUNet ID Account home directories,
all the software available in
/usr/pubsw, and hundreds of other
AFS cells worldwide.
