Topic: OpenAFS & The Andrew File System Distributed Storage Model

Introduction & Description of Talk:

These are Jeff's words :-) ...

This month Jeffrey Altman will return to Unigroup for his Nth talk over the last twenty years. Always thought provoking and never boring, Jeff will provide his insights into the Andrew File System (AFS) distributed storage model with an eye towards scaling performance for modern day.

Outline of Talk:

The Andrew File System (AFS) is a distributed file system originally developed by Carnegie Mellon University and IBM in the early 1980s. It was commercialized by Transarc and IBM in the 1990s and the OpenAFS open source project was born on 1 Nov 2000. Unlike other distributed file systems, AFS is unique in that it supported a globally accessible name space, federated authentication, fine grained access control and a data publishing and replication mechanism a decade before the world wide web.

AFS is currently deployed at hundreds (perhaps thousands) of organizations around the globe providing centrally managed storage for home directories, departmental and project storage, software/documentation/configuration distribution, and web site hosting. For more details on the history of AFS and OpenAFS please watch the presentations given at CERN earlier this year.

Your File System Inc. (YFS) was founded in October 2007 with the goal of building a globally distributed storage system for the masses using the AFS distributed storage model. There was only one small problem: AFS was designed in the 1980s and the computing, storage network architectures of 21st century system are very different from the assumptions that AFS was built on. For the last four years, YFS has worked to update OpenAFS to match the scalability needs of today's heterogeneous systems.

   The Future of the Andrew File System (Jeffrey Altman at CERN)


Jeffrey Altman is a computer scientist and entrepreneur with a long history of contributing to open source projects including: Kermit, OpenSSL, MIT Kerberos, OpenAFS, and Heimdal among others. He is the founder of Secure Endpoints, Inc. and Your File System, Inc.

A frequent speaker at Unigroup, Jeffrey is known for his informative talks that keep attendees at the meeting long past the running of the last train home.


Your File System, Inc. is a four year old startup in the distributed storage space which just completed a U.S. Department of Energy SBIR Phase II grant to produce a 21st Century successor to AFS.


Addison-Wesley Professional/Prentice Hall PTR, and O'Reilly have been kind enough to provide us with review copies of some of their books, which we will continue to raffle off as giveaways at our meetings. The publishers always ask that the persons receiving the books provide a review and/or feedback about their books.

Unigroup would like to thank both companies for the support provided by their User Group programs.

As always, all of the books will be available for review at the start of the meeting.

We have some Solaris Related CD-ROMs from our friends at the local NYC Sun Microsystems Office.

       ! Students: We are looking for proof that you are
         currently enrolled in classes (rather than working
         full-time), and as such, your Student ID should show
         a CURRENT date.  We have been presented Student IDs
         containing NO dates whatsoever, and in the
         current environment, perpetual/non-expiring access
         to university facilities just does not feel right.

         additional proof of current enrollment.  Thanks.
