All computing environments have file systems. A distributed +file system takes advantage of the interconnected nature of the network +by storing files on more than one computer in the network and making +them accessible to all of them. In other words, the responsibility for +file storage and delivery is "distributed" among multiple machines +instead of relying on only one.</p> +<p><b>File Server Machines</b></p> +<p>File server machines store the files in the distributed file +system, and a server process running on the file server machine delivers +and receives files.</p> +<p><b>Volumes</b></p> +<p>A volume is a conceptual container for a set of related files +that keeps them all together on one file server machine partition. +Volumes can vary in size, but are (by definition) smaller than a +partition. You can maintain maximum system efficiency by moving volumes +to keep the load balanced evenly among the different machines. If a +partition becomes full, the small size of individual volumes makes it +easy to find enough room on other machines for them. Each volume +corresponds logically to a directory in the file tree and keeps +together, on a single partition, all the data that makes up the files in +the directory (including possible subdirectories). By maintaining (for +example) a separate volume for each user's home directory, you keep all +of the user's files together, but separate from those of other users. +This is an administrative convenience that is impossible if the +partition is the smallest unit of storage.</p> + +</body> +</html>
