The Zebra striped network file system

Zebra is a network file system that increases throughput by striping file data across multiple servers. Rather than striping each file separately, Zebra forms all the new data from each client into a single stream, which it then stripes using an approach similar to a log-structured file system. This provides high performance for writes of small tiles as well as for reads and writes of large files. Zebra also writes parity information in each stripe in the style of RAID disk arrays; this

A prototype implementation of Zebra, built in the Sprite operating system, provides 4-5 times the throughput of the standard Sprite file system or NFS for large files and a 20%-3x improvement for writing small files.
