Abstract—In this paper we present a brief analysis on the working and design of Google file System with its performance analysis. A brief Comparison of Google File system with other Distributed File Systems (DFS) namely HDFS, Global FS, GPFS and sector is also presented. Although Google shares many similarities with other DFSs but still it is unique in its design which is made specifically to serve Google’s heavy workload. GFS’s Architecture has a single master which is responsible for performing some major duties as explained in the Architecture session. Reliability of data is maintained through triple replication of data. So it also provides fast recovery and fault tolerance. Comparison and future consideration enables the reader to understand the current situation of GFS and its place in the future world. This paper not only explains GFS and its comparative study but also explains the complete background of the technology and its future.

Index Terms—Distributed file system, HDFS, global FS.
