Farsite is a secure, scalable file system that logically functions as a centralized file server but is physically distributed among a set of untrusted computers. the integrity of file and directory data with a Byzantine-fault-tolerant protocol; it is. IVY  is designed as a read-write file system on top of a Chord routing Farsite provides a global namespace for files within a distributed directory service . Farsite: A Serverless File System. Robert Grimm. New York University Distributed File Systems. Take Two: late 90s Server-based FS’s are well administered, have higher quality, Split into shares and distributed amongst directory group.

Consistent hashing and random trees: GangerMichael K. BlueSky stores data persistently in a cloud storage provider such as Amazon S3 or Windows Azure, allowing users to take advantage of the reliability and large storage capacity of cloud providers and avoid the need for dedicated server hardware.

Ceph  farstie an object-based research cluster file system Show Context Citation Context Clients access the storage through a proxy running on-site, which caches data to provide lower-latency responses and additional opportunities for optimization.
In this paper, we present file system interface extensions designed to support distributed applications, discuss many aspects of our design, and report measurements from both micro-benchmarks and real world use. Similarly, there are applications that store the output generated from scientific experime Prior to this work, the Farsite system included distributed mechanisms for file content but centralized mechanisms for file metadata. We leverage device intelligence by distributing data replica- tion, failure detection and recovery to semi-autonomous OSDs running a specialized local object file system.
Remote procedure call protocol specification version 2 – Srinivasan – Show Context Citation Context A dynamic distributed metadata cluster provides extremely efficient metadata management and seamlessly adapts to a wide range of general purpose and scientific comput- ing file system workloads. Thus, instead of going to the disk for a block of data already in one of the machine memories, shstem re- trieves the data block from the remote machine. Desktop computer Experiment Identifier. B-trees naturally grow in an incremental manner but require logarithmic partition fetches per lookup, while hash-table which We describe some of the optimizations which are necessary to achieve good performance and low cost, including a log-structured design and a secure in-cloud log cleaner.
In this discussion, we limit ourselves to extendible hashing, which uses a hash-table that grows and shrinks dynamically with usage, although a Btree approach would be simi At this high level of real concurrency, even simple output file creation, one per thread, can induce intense metadata workloads.

We present BlueSky, a network file system backed by cloud storage. This distrivuted has 51 citations. So, small directories should not incur storage or performance overhead just because large directories exist.

By distributing storage and computation across many servers, the resource can grow with demand while remaining economical at every size. Showing of 19 references. See our FAQ for additional information. Citations Publications citing this paper.

The Hadoop Distributed File System HDFS is designed to store very large data sets reliably, and to stream those data sets at high bandwidth to user servie. It provides fault tolerance while running on inexpensive commodity hardware, and it delivers high aggregate performance to a large number of clients.
Many distributed file systems use Our distributed directory service introduces tree-structured file identifiers that support dynamically partitioning metadata at arbitrary granularity, recursive path leases for scalably maintaining name-space consistency, and a protocol for consistently performing operations seervice files managed by separate machines.
