Managing Afs: The Andrew File Systemby Richard Campbell
Synopses & Reviews
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:
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.
Book News Annotation:
Explains how the Andrew File System (AFS) works, how it implements the client/server model, and how to use it. After an overview of the benefits of AFS and AFS vocabulary and architecture, chapters are devoted to administrative specifics, the user and developer perspectives, the archiving system, debugging, and large-site administration. Includes real-world case studies, and a guide to evaluating, piloting, and implementing AFS throughout the organization and connecting to other AFS sites around the world.
