A Distributed File System

This research paper is a survey of the present state of design and implementation of distributed file systems. In a distributed file system, one or more central servers store files that can be accessed, with proper authorization rights. It consists of four parts: an Introduction of Distributed file system, implementation, architecture and component of distributed file system and their design goals for good distributed file system i.e. transparency – the main goal of good DFS. In this paper we also discuss some distributed file systems like NFS, CIFS, OwFS and HDFS. We explain features, architecture of above file system. This paper also include the criteria for choosing right Distributed file system of our need and recommendation foe right Distributed File System .The above file systems are also compared on the basis of File size, Analytic functionality, TCO and their selection criteria.   This research also included the future aspect of distributed file systems like the problem we based in current DFS like transparency and at last the conclusion of the whole paper on the basis of above survey.
