TAILIEUCHUNG - Lecture Operating system concepts (Fifth edition): Module 17 - Avi Silberschatz, Peter Galvin

Module 17 - Distributed-file systems. Chapter 17 looks at the current major research and development in distributed-file systems (DFS). The purpose of a DFS is to support the same kind of sharing when the files are physically dispersed among the various sites of a distributed system. | Module 17: Distributed-File Systems Background Naming and Transparency Remote File Access Stateful versus Stateless Service File Replication Example Systems Applied Operating System Concepts Background Distributed file system (DFS) – a distributed implementation of the classical time-sharing model of a file system, where multiple users share files and storage resources. A DFS manages set of dispersed storage devices Overall storage space managed by a DFS is composed of different, remotely located, smaller storage spaces. There is usually a correspondence between constituent storage spaces and sets of files. Applied Operating System Concepts DFS Structure Service – software entity running on one or more machines and providing a particular type of function to a priori unknown clients. Server – service software running on a single machine. Client – process that can invoke a service using a set of operations that forms its client interface. A client interface for a file service is formed
