Book excerpt: "This thesis describes the design of an operating system independent distributed file system (DFS) and details the implementation, on a cooperating set of server computers interconnected by means of a communications network. The DFS provides the mechanism by which the file systems of these physically dispersed units are integrated into a single logical unit. Users and application programs thus have the illusion that their files are on a single computer system, even though in reality they may be physically distributed around the network. This location transparency frees users from having to remember details such as the current location of the file and also affords considerable mobility, allowing access to files from any workstation. In addition, automatic storage replication and an atomic transaction mechanism provides high reliability and improved availability in the distributed environment in the face of site failure."--Abstract.

This book was released on 2012-12-06 with total page 222 pages. Available in PDF, EPUB and Kindle. Book excerpt: In general, distributed systems can be classified into Distributed File Systems (DFS) and Distributed Operating Systems (DOS). The survey which follows distinguishes be tween DFS approaches in Chapters 2-3, and DOS approaches in Chapters 4-5. Within DFS and DOS, I further distinguish "traditional" and object-oriented approaches. A traditional approach is one where processes are the active components in the systems and where the name space is hierarchically organized. In a centralized environment, UNIX would be a good example of a traditional approach. On the other hand, an object-oriented approach deals with objects in which all information is encapsulated. Some systems of importance do not fit into the DFS/DOS classification. I call these systems "closely related" and put them into Chapter 6. Chapter 7 contains a table of comparison. This table gives a lucid overview summarizing the information provided and allowing for quick access. The last chapter is added for the sake of completeness. It contains very brief descriptions of other related systems. These systems are of minor interest or do not provide transparency at all. Sometimes I had to assign a system to this chapter simply for lack of adequate information about it.

Book excerpt: ABSTRACT: Distributed Conferencing System (DCS) is a platform that supports collaboration in a distributed environment. Distributed File System (DFS) provides the file system of DCS. Distributed file systems face some peculiar challenges. They must provide a uniform name space for users, along with location independence and location transparency. A file can be edited simultaneously at different locations. If the changes are not coordinated, the file may become inconsistent and the resulting unpredictability can be frustrating to users. An important characteristic of a distributed system is that at almost all times, some node or another will be unavailable. DFS must ensure that the system is reliable and highly fault-tolerant. Currently available distributed file systems cannot support DCS. They are not designed for an environment where a high level of concurrency is common. They assume that simultaneous writes are unlikely and do not support an adequate level of concurrency control. Most file systems make use of primary copy replication which has a large overhead. Others use read-only replication. DFS supports a high level of concurrency. It uses an immutable versioning scheme where, every time a file is closed, it is saved as a new version of the file. This allows multiple users to edit and save the file simultaneously, without the danger of interleaving file blocks. At the same time, it makes sure that no changes are lost. DFS provides fault tolerance and ensures high reliability by replicating files across multiple sites. In addition, it supports file migration. The immutable versioning scheme also gets rid of the problem of synchronizing replicas.
Download or read book z OS Distributed File Service zSeries File System Implementation z OS V1R13 written by Paul Rogers and published by IBM Redbooks. This book was released on 2012-10-18 with total page 518 pages. Available in PDF, EPUB and Kindle. Book excerpt: The z/OS® Distributed File Service zSeries® File System (zFS) is a z/OS UNIX® file system that can be used like the Hierarchical File System (HFS). zFS file systems contain files and directories, including Access Control Lists (ACLs), that can be accessed with the z/OS HFS application programming interfaces (APIs). zFS file systems can be mounted into the z/OS UNIX hierarchy along with other local or remote file system types (for example, HFS, TFS, AUTOMNT, NFS, and so on). zFS does not replace HFS, but it is the z/OS UNIX strategic file system and IBM® recommends migrating HFS file systems to zFS. Beginning with z/OS V1R7, there are no restrictions for file system structures that should be kept as HFS instead of zFS. This IBM Redbooks® publication helps you to install, tailor, and configure new zFS file systems. This information can be used by system administrators who work with the zFS component of the IBM z/OS Distributed File Service base element. The book provides a broad description of the new architecture of the zFS file system for all releases up to zFS V1R13. You can use it as a reference when converting HFS file systems to zFS file systems. It will help you to create a solution for migrating to zFS file systems, and to understand the performance differences between HFS file systems and zFS file systems.
Download or read book A Distributed File System for Distributed Conferencing System written by Philip S. Yeager and published by . This book was released on 2003 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: ABSTRACT: This thesis presents a Distributed File System (DFS) for the Distributed Conferencing System (DCS). DCS is a system that is developed to allow users to do real-time collaborative work in a distributed environment, while providing the tools and applications to make this process more efficient and easier. In distributed file systems, efficient and accurate management of files is vital. Files can be replicated and stored at physically dispersed locations. They can also be concurrently read and written by numerous people. If these actions are not specially controlled, the resulting files and system can be unpredictable. The work in this thesis is designed to provide an efficient and reliable file system for users to access and modify shared files within DCS. Contemporary distributed file systems such as the Network File System (NFS), Andrew File System (AFS), Coda, and others do not meet the vast needs of DCS.

Download or read book Parallel I O for High Performance Computing written by John M. May and published by Morgan Kaufmann. This book was released on 2001 with total page 392 pages. Available in PDF, EPUB and Kindle. Book excerpt: "I enjoyed reading this book immensely. The author was uncommonly careful in his explanations. I'd recommend this book to anyone writing scientific application codes." -Peter S. Pacheco, University of San Francisco "This text provides a useful overview of an area that is currently not addressed in any book. The presentation of parallel I/O issues across all levels of abstraction is this book's greatest strength." -Alan Sussman, University of Maryland Scientific and technical programmers can no longer afford to treat I/O as an afterthought. The speed, memory size, and disk capacity of parallel computers continue to grow rapidly, but the rate at which disk drives can read and write data is improving far less quickly. As a result, the performance of carefully tuned parallel programs can slow dramatically when they read or write files-and the problem is likely to get far worse. Parallel input and output techniques can help solve this problem by creating multiple data paths between memory and disks. However, simply adding disk drives to an I/O system without considering the overall software design will not significantly improve performance. To reap the full benefits of a parallel I/O system, application programmers must understand how parallel I/O systems work and where the performance pitfalls lie. Parallel I/O for High Performance Computing directly addresses this critical need by examining parallel I/O from the bottom up. This important new book is recommended to anyone writing scientific application codes as the best single source on I/O techniques and to computer scientists as a solid up-to-date introduction to parallel I/O research. Features: An overview of key I/O issues at all levels of abstraction-including hardware, through the OS and file systems, up to very high-level scientific libraries. Describes the important features of MPI-IO, netCDF, and HDF-5 and presents numerous examples illustrating how to use each of these I/O interfaces. Addresses the basic question of how to read and write data efficiently in HPC applications. An explanation of various layers of storage - and techniques for using disks (and sometimes tapes) effectively in HPC applications.
