Hadoop's HDFS filesystem, is designed to store similar or greater quantities of data on commodity hardware — that is, datacenters without RAID disks and a storage area network (SAN). HDFS also breaks files up into blocks, and stores them on different filesystem nodes. GPFS has full Posix filesystem semantics.
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Gluster, Lustre and old (1.6.x) version of MooseFS, although this document is from 2013 and a lot of information are outdated (e.g. MooseFS had no HA for Metadata Server at that time).
General Parallel File System (GPFS) IBM: Proprietary: Linux, Windows and AIX A POSIX-compliant, high-performance, parallel filesystem. Support synchronous replication between attached block storage, and asynchronous replication to remote filesystems. Also support erasure coding on dual homed SAS attached storage, and distributed over multiple ...

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 ...
Apache Hadoop (/ h ə ˈ d uː p /) is a collection of open-source software utilities for reliable, scalable, distributed computing.It provides a software framework for distributed storage and processing of big data using the MapReduce programming model.
IBM Scale Out Network Attached Storage (SONAS) was the IBM enterprise x86-based storage platform based on GPFS technology, and released in 2010 [31] as hardware product. This system implements NAS based protocols over a large-scale global name space.
Google File System (GFS or GoogleFS, not to be confused with the GFS Linux file system) is a proprietary distributed file system developed by Google to provide efficient, reliable access to data using large clusters of commodity hardware.
