Microsoft Distributed file system (Dfs) is Windows 2000 Server software that makes it easier for you to find and manage data on your enterprise network. Dfs provides mapping and a uniform naming convention for collections of servers, shares, and files. Dfs adds the capability of organizing file...
distributed file system是clustered file system 的一种: Distributed file systemsdo not share block level access to the same storage but use a networkprotocol. These are commonly known asnetwork file systems, even though they are not the only file systems that use the network to send data. Distr...
Distributed file system (Dfs) is a Microsoft® Windows® 2000 service that assists network administrators in managing file resources on distributed enterprise networks. Dfs also makes finding files on networks easier for users by creating a single hierarchical view of the shared data on different...
The Distributed File System (DFS) functions provide the ability to logically group shares on multiple servers and to transparently link shares into a single hierarchical namespace. DFS organizes shared resources on a network in a treelike structure.Distributed...
摘要We have designed and implemented the Google File System,a scalable distributed file system for large distributed data-intensive applications. It provides fault tolerance while running on inexpen…
