State of the Art in Distributed File Systems: Increasing Performance

Need of storing huge amounts of data has grown over the past years. The data should be stored for future reuse or for sharing among users. Data files can be stored on a local file system or on a distributed file system. A distributed file system provides many advantages such as reliability, scalability, security, etc. This paper shows new trends in these systems with a focus on increasing performance. These include the organization of data and metadata storage, usage of caching, and design of replication algorithms.
