NFS Enters a Parallel Universe

“NFS was originally designed to solve the problem of remote
access to home directories and supporting diskless workstations and
servers over local area networks. With the advent of cheaper
high-performance computing in the form of Linux compute clusters,
multi-core processors and blades, the demands for higher
performance file access have risen sharply. It’s no wonder that a
protocol designed for 1984 speeds would be unable to cope….

“pNFS is a key feature of NFS 4.1. The p in pNFS stands for
parallel, and pNFS will provide parallel I/O to file systems
accessible over NFS. It enables the storage administrator to do
things like stripe a single file across multiple NFS servers.”
