Some researchers have made a functional and experimental analysis of several distributed file systems including HDFS, Ceph, Gluster, Lustre and old (1.6.x) version of MooseFS, although this document is from 2013 and a lot of information are outdated (e.g. MooseFS had no HA for Metadata Server at that time).
The Be File System (BFS) is the native file system for the BeOS. In the Linux kernel, it is referred to as "BeFS" to avoid confusion with Boot File System . BFS was developed by Dominic Giampaolo and Cyril Meurillon over a ten-month period, starting in September 1996, [ 2 ] to provide BeOS with a modern 64-bit -capable journaling file system ...

Distributed fault-tolerant replication of data between nodes (between servers or servers/clients) for high availability and offline (disconnected) operation. Coda from Carnegie Mellon University focuses on bandwidth-adaptive operation (including disconnected operation) using a client-side cache for mobile computing. It is a descendant of AFS-2.
Additionally, a variant of AFS, the DCE Distributed File System (DFS) was adopted by the Open Software Foundation in 1989 as part of their Distributed Computing Environment. Finally AFS (version two) was the predecessor of the Coda file system.
But what Russell and Norvig do is generalize the "true DFS", rather than BFS, so their BFS is "DFS with a queue instead of a stack" rather than the other way around. So the current statement of the difference in the article is confusing for AIMA readers, since it presumes a particular version of BFS.
Beam search uses breadth-first search to build its search tree. At each level of the tree, it generates all successors of the states at the current level, sorting them in increasing order of heuristic cost. [2] However, it only stores a predetermined number, , of best states at each level (called the beam width). Only those states are expanded ...
A depth-first search (DFS) is an algorithm for traversing a finite graph. DFS visits the child vertices before visiting the sibling vertices; that is, it traverses the depth of any particular path before exploring its breadth. A stack (often the program's call stack via recursion) is generally used when implementing the algorithm.
