WIDE AREA DISTRIBUTED FILE SYSTEMSA SCALABILITY AND PERFORMANCE SURVEY KOVENDHAN PONNAVAIKKO AND JANAKIRAM DHARANIPRAGADA

Abstract. Recent decades have witnessed an explosive growth in the amounts of digital data in various elds of arts, science and engineering. Such data is generally of interest to a large number of people spread over wide geographical areas. Over the years, several Distributed File Systems (DFS) have, to varying degrees, addressed this requirement of sharing large amounts of data, stored in the form of les, among several users and applications. Scalability and performance are two important measures that determine the suitability of a le system for the applications executing over them. We perform a detailed comparative analysis of popular distributed le systems in terms of these measures in our survey
