Paper Abstract

The Common File System (CFS) is a file management and file storage system for the Los Alamos National Laboratory's computer network. The CFS is organized as a hierarchical storage system: active files are stored on fast-access storage devices, larger, less active files are stored on slower, less expensive devices, and archival files are stored offline. Files are automatically moved between the various classes of storage by a file migration program that analyzes file activity, file size, and storage device capabilities. This has resulted in a cost-effective system that provides both fast access and large data storage capability (over 9 trillion bits currently stored). A large capacity (1014 bits), reliable Digital Optical Storage System would replace the offline storage as the archival part of the CFS and might also be used for active storage if it had a reasonable file access time.
