Infinit
Infinit International, Inc
proprietary
cross-platform
A POSIX-compliant file system for both local area network and wide area networks. Infinit replicates blocks of data between the various storage resources composing the infrastructure (being local or through cloud API) in order to guarantee data reliability (durability and availability) through Byzantine fault tolerance and data rebalancing (i.e.
LizardFS
Skytechnology
GPL
cross-platform
An open source, highly available POSIX-compliant file system that supports Windows clients.
Lustre
originally developed by Cluster File Systems and currently supported by OpenSFS
GPL
Linux
A POSIX-compliant, high-performance filesystem used on a majority of systems in the Top-500 list of HPC systems. Lustre has high availability via storage failover.
MapR FS
MapR
Proprietary
Linux
Highly scalable, POSIX compliant, fault tolerant, read/write filesystem with a distributed, fault tolerant metadata service. It provides an HDFS and NFS interface to clients as well as a noSQL table interface and Apache Kafka compatible messaging system.
MooseFS
Core Technology
GPLv2 / proprietary
cross-platform (Linux, NetBSD, FreeBSD, macOS, OpenSolaris)
MooseFS is a fault tolerant, highly available and high performance scale-out network distributed file system. It spreads data over several physical commodity x86 servers, which are visible to the user as one namespace.
ObjectiveFS
Objective Security Corporation
proprietary
Linux, macOS
POSIX-compliant shared distributed filesystem. Uses object store as a backend. Runs on AWS S3, GCS and object store devices.
OneFS distributed file system
Isilon
-
FreeBSD
BSD-based OS on dedicated Intel based hardware, serving NFS v3 and SMB/CIFS to Windows, macOS, Linux and other UNIX clients under a proprietary software.
OIO-FS
OpenIO
Proprietary
Linux
OIO-FS provides file-oriented access to OpenIO SDS object storage backend. It is based on FUSE technology and presents a POSIX file system to users.
PanFS
Panasas
Proprietary
Linux, macOS, FreeBSD
A POSIX-compliant, high-performance, parallel filesystem used by HPC clusters. It uses erasure coding and snapshots for data protection, is based upon a scale-out object store, and is focused on transparent failure recovery and ease of use.
RozoFS
Rozo Systems
GNU GPLv2
Linux
A POSIX DFS focused on fault-tolerance and high-performance, based on the Mojette erasure code to reduce significantly the amount of redundancy (compared to plain replication).
Scality
Scality ring
Proprietary software
Linux
A POSIX file system focused on high availability and performance. Also provides S3/REST/NFS interfaces.
Tahoe-LAFS
Tahoe-LAFS Software Foundation
GNU GPL 2+ and other
Windows, Linux, macOS
A secure, decentralized, fault-tolerant, peer-to-peer distributed data store and distributed file system.
WekaIO Matrix
WekaIO
Proprietary software
Linux
An extreme performance, NVMe-optimized parallel filesystem that includes Distributed Coding (similar to Erasure Coding), instantaneous snapshots, tiering to S3 datastores, runs in the cloud or on-prem.
XtreemFS
Contrail E.U. project, the German MoSGrid project and the German project "First We Take Berlin"
open-source (BSD)
Linux, Solaris, macOS, Windows
A cross-platform file system for wide area networks. It replicates the data for fault tolerance and caches metadata and data to improve performance over high-latency links.

Question: What differentiates Lustre and MapR FS?
Answer: Lustre is a high-performance distributed parallel file system for Linux and MapR FS is a distributed high-performance file system that exhibits table and messaging system.
