Abstract

With the rapid advances in computing technology, there is an explosion in media that needs to collected, cataloged, stored and accessed. With the speed of disks not keeping pace with the improvements in processor and network speed, the ability of network file systems to provide data to demanding applications at an appropriate rate is diminishing. In this paper, we propose to enhance the performance of network file systems by providing an Intermediate bank of cache servers between the client and server ...

Abstract

NFS has traditionally used TCP or UDP as the underlying transport. However, the overhead of these stacks has limited both the performance and scalability of NFS. Recently, high-performance network such as InfiniBand have been deployed. These networks provide low latency of a few microseconds and high bandwidth for large messages up to 20 Gbps. Because of the unique characteristics of NFS protocols, previous designs of NFS with RDMA were unable to exploit the improved bandwidth of networks such as InfiniBand. Also, ...

Abstract

Cluster file systems and storage area networks (SAN) make use of network IO to achieve higher IO bandwidth. Effective integration of networking mechanisms is important to their performance. In this paper, we perform an evaluation of a popular cluster file system, Lustre, over two of the leading high speed cluster interconnects: InfiniBand and Quadrics. Our evaluation is performed with both sequential IO and parallel IO benchmarks in order to explore the capacity of Lustre under different communication characteristics. Experimental results show ...
