A Look at Modern File Systems
نویسندگان
چکیده
Introduction In recent years, a great deal of work has been done on distributed and parallel file systems. Although the motivations behind these two types of file systems are quite different, they share many underlying characteristics and techniques. Distributed file systems need to provide clients with efficient, usable, and scalable high-bandwidth access to stored data. Parallel file systems have a somewhat more straightforward goal: to allow multiple processes working together as a single task force to access a shared file or files in parallel. In these specialized systems, speed and scalability are the most important considerations, while issues like portability and ease of use are secondary. This paper will examine eight modern distributed and parallel file systems, looking at the design principles and goals behind each, their actual implementations, the advantages and disadvantages each entails, the innovations each system introduces, and the performance and scalability each offers. The paper concludes with a brief comparison of these systems.
