This paper describes a simple distributed mechanism for caching files among a networked collection of workstations. We have implemented it as part of the Sprite operating system. In Sprite, file...
The Zebra Striped Network File System (2001)
John H. Hartman, John K. Ousterhout
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...
