A New Way to High Performance NFS for Clusters

For its simplicity, reliability and maturity, NFS is widely-used in clusters. However, due to its high overheads and implementation limitations, the standard NFS cannot fully exert the potential abilities provided by multiple network channels and multiple SCSI channels on the server. In this paper, we present a new efficient way to high performance NFS implementation for cluster applications. By adding mechanisms to make good use of NFS server´s multiple communication channels and multiple I/O channels, CluserNFS can potentially provide better I/O performance than standard NFS, as illustrated by our simulation experiment results.
