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Gluster, Lustre and old (1.6.x) version of MooseFS, although this document is from 2013 and a lot of information are outdated (e.g. MooseFS had no HA for Metadata Server at that time).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 MooseFS follows similar design principles as Fossil, Google File System, Lustre or Ceph. The file system comprises three components: Metadata server (MDS) — manages the location (layout) of files, file access and namespace hierarchy. The current version of MooseFS does support multiple metadata servers and automatic failover. Clients only ...
Category for distributed file systems. Distributed file systems are network file systems where the server can be distributed across several physical computer nodes. File systems that share access to the same block storage are shared disk file systems.
Its file storage capability is compatible with the Apache Hadoop Distributed File System (HDFS) API but with several design characteristics that distinguish it from HDFS. Among the most notable differences are that MapR-FS is a fully read/write filesystem with metadata for files and directories distributed across the namespace, so there is no ...
The Andrew File System heavily influenced Version 4 of Sun Microsystems' popular Network File System (NFS). 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 ...
Distributed Data Management Architecture (DDM) is IBM's open, published software architecture for creating, managing and accessing data on a remote computer. DDM was initially designed to support record-oriented files; it was extended to support hierarchical directories, stream-oriented files, queues, and system command processing; it was further extended to be the base of IBM's Distributed ...
The Exports server is a user-space daemon; the metadata are stored synchronously to a usual file system (the underlying file system must support extended attributes). Storage servers — (Chunk Server) store the chunks. The Chunk server is also a user-space daemon that relies on the underlying local file system to manage the actual storage.
