A Look at pNFS as a Tool for Standardizing Storage Clusters
Thursday, February 26th, 2009Scalable Performance with pNFS as a Standardized Extension to NFSv4
Garth Goodson et al. have authored an introduction to standardizing storage clusters using the pNFS (parallel NFS) protocol as part of the NFSv4.1 specification to bridge the gap between current NFS protocols (versions 2, 3, and 4) and parallel cluster file system interfaces. While current NFS protocols force clients to access all files on a given file-system volume from a single server node (which can become a bottleneck for scalable performance), pNFS as a standardized extension to NFSv4 provides clients with scalable end-to-end performance and the flexibility to interoperate with a variety of clustered storage service architectures.
