The LFS Storage Manager
Advances in computer system technology in the areas of CPUs, disk subsystems, and volatile RAM memory are combining to create performance problems existing file systems are ill-equipped to solve. This paper identifies the problems of using the existing UNIX file systems on 1990’s technology and presents an alternative file system design that can use disks an order-of-magnitude more efficiently ...
متن کاملOverview of the Spiralog File System
wide file system with integrated, on-line backup and restore capability and support for multiple file system personalities. It incorporates a number of recent ideas from the research community, including the log-structured file system (LFS) from the Sprite file system and the ordered write back from the Echo file system. The Spiralog file system is fully integrated into the OpenVMS operating sy...
متن کاملAn Implementation of a Log-Structured File System for UNIX
Research results [ROSE91] demonstrate that a log-structured file system (LFS) offers the potential for dramatically improved write performance, faster recovery time, and faster file creation and deletion than traditional UNIX file systems. This paper presents a redesign and implementation of the Sprite [ROSE91] log-structured file system that is more robust and integrated into the vnode interfa...
متن کاملThe Zebra Striped
Zebra is a network file system that increases throughput by striping the 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. Thm provides high performance for writes of small files as well as for reads and writes of large ...
متن کاملZebra: A Striped Network File System
This paper presents the design of Zebra, a striped network file system. Zebra applies ideas from log-structured file system (LFS) and RAID research to network file systems, resulting in a network file system that has scalable performance, uses its servers efficiently even when its applications are using small files, and provides high availability. Zebra stripes file data across multiple servers...
