The Central 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 capabilties. This has resulted in a cost-effective system that provides both fast access and large data storage capability.
