Designed to handle terabytes of data and thousands of users distributed across large networks, the Andrew File System (AFS) works as a Unix and Windows NT add-on that replaces the standard Network File System (NFS). The basic idea of AFS is that all users of a network get a common picture of the file system even though it represents data that's stored on many different machines. Originally developed at Carnegie Mellon University and now commercially promoted by Transarc Corporation, AFS has a solid presence in very large commercial networks. Its popularity seems likely to trickle down to midsize organizations as businesses of all kinds become more network-intensive. Campbell's book takes the ponderous set of AFS documentation and distills it into a collection of task- and question-oriented segments. The book opens with an analysis of AFS architecture that will prove useful to those thinking about deploying AFS. Managing AFS then covers hardware requirements, volume structure decisions, and client administration in depth. Following a discussion of AFS's implementation of Kerberos security, Campbell gets into task-oriented discussions, covering groups, rights, archive procedures, and disaster recovery. One interesting chapter presents AFS case studies, highlighting how IBM, Morgan Stanley, and the University of Michigan are using the file system. An appendix details the various AFS command suites in a sort of abbreviated man-page format. Throughout Managing AFS, the text is clear and readable--even entertaining. If you're wondering how AFS might work on your network or you want to know the easiest way to set up a user account, this book meets your needs. Synopsis
Written for UNIX system administrators, this guide deals with AFS, a high-end UNIX filing system developed at Carnegie Mellon University and used widely in many industries such as banking and finance. This title explains how to manage AFS to its greatest effect including the installation of an adequate server setup to handle thousands of clients with a minimum of administrator and hardware overhead. . From the Back Cover
Master AFS, the Internet's most scalable, manageable distributed file system.
One technology already delivers the scalability, flexibility, power, and centralized file systems management the entire computer industry keeps promising: the Andrew File System (AFS). That's why hundreds of large institutions worldwide are already using AFS to reliably support their users' distributed file storage needs.
Managing AFS is the first book that brings together the critical information you need to build and maintain a reliable AFS-based distributed file system. Learn how AFS works, how it implements the client/server model, and why it's uniquely well-designed to serve the needs of today's organizations. Then, discover how to:
*Make the right architectural and topology choices to optimize AFS up front
*Take full advantage of AFS' powerful large-scale administration tools
*Slash desktop administration costs with AFS file caching and heterogeneous system support
*Set up and maintain user accounts(including how to create “dataless clients”
*Archive AFS data using built-in tools or third-party options
*Improve reliability through replication and automatic client failover
*Provide unified file services for UNIX® and Windows NT® desktops
Managing AFS includes detailed coverage of AFS security, including user authentication and Kerberos; AFS debugging and monitoring; solutions for providing access to Windows NT clients; and much more. You'll also find real-world AFS case studies, and a step-by-step guide to evaluating, piloting, and rolling out AFS throughout your organization and connecting to other AFS sites around the world.
If you're not looking for a better distributed storage solution yet, you will be soon. There's only one best-of-breed solution: AFS. And there's only one definitive guide to this revolutionary technology: Managing AFS. About the Author
RICHARD CAMPBELL has worked for the last five years as a distributed computing consultant on Wall Street. Previously, he was a senior researcher at the Institutional File System Project at the University of Michigan, which established AFS as the distributed file system for the campus of over 30,000 users.
