Glusterwikipedia
Gluster Inc. was a software company that provided an open source platform for scale-out public and private cloud storage.

Network-attached storage

NASnetwork-attached storagenetwork attached storage
Gluster based its product on GlusterFS, an open-source software-based network-attached filesystem that deploys on commodity hardware.
Starting in the early 2000s, a series of startups emerged offering alternative solutions to single filer solutions in the form of clustered NAS – Spinnaker Networks (acquired by NetApp in February 2004), Exanet (acquired by Dell in February 2010), Gluster (acquired by RedHat in 2011), ONStor (acquired by LSI in 2009), IBRIX (acquired by HP), Isilon (acquired by EMC – November 2010), PolyServe (acquired by HP in 2007), and Panasas, to name a few.

Red Hat Storage Server

In June 2012, Red Hat Storage Server was announced as a commercially supported integration of GlusterFS with Red Hat Enterprise Linux.
It is based on open source technologies such as GlusterFS and Red Hat Enterprise Linux.

Ceph (software)

The product was first marketed as Red Hat Storage Server, but in early 2015 renamed to be Red Hat Gluster Storage since Red Hat has also acquired the Ceph file system technology.

OpenStack

Native-protocol mounts may then be re-exported e.g. via the kernel NFSv4 server, SAMBA, or the object-based OpenStack Storage (Swift) protocol using the "UFO" (Unified File and Object) translator.
In addition to local Linux server storage, it can use storage platforms including Ceph, CloudByte, Coraid, EMC (ScaleIO, VMAX, VNX and XtremIO), GlusterFS, Hitachi Data Systems, IBM Storage (IBM DS8000, Storwize family, SAN Volume Controller, XIV Storage System, and GPFS), Linux LIO, NetApp, Nexenta, Nimble Storage, Scality, SolidFire, HP (StoreVirtual and 3PAR StoreServ families) and Pure Storage.

Gluster was acquired by Red Hat on October 7, 2011.

The final volume may then be mounted by the client host using its own native protocol via the FUSE mechanism, using NFS v3 protocol using a built-in server translator, or accessed via gfapi client library.

GFS2

GFSGFS2
GFS2 differs from distributed file systems (such as AFS, Coda, InterMezzo, or GlusterFS) because GFS2 allows all nodes to have direct concurrent access to the same shared block storage.

Docker, Inc.

Docker
In July, 2013, Benjamin Golub (formerly of Plaxo and Gluster) became chief executive.

Hypertable

Hypertable runs on top of a distributed file system such as the Apache HDFS, GlusterFS or the CloudStore Kosmos File System (KFS).

Proxmox Virtual Environment

ProxmoxProxmox VE
Proxmox VE supports local storage with LVM group, directory and ZFS, as well as network storage types with iSCSI, Fibre Channel, NFS, GlusterFS, CEPH.

Cuneiform (programming language)

Cuneiform
If run in distributed mode it drives a POSIX-compliant distributed file system like Gluster or Ceph (or a FUSE integration of some other file system, e.g., HDFS).

Libguestfs

libguestfs
libguestfs can access nearly any type of file system including: all known types of Linux filesystem (ext2/3/4, XFS, btrfs, etc.), any Windows filesystem (VFAT and NTFS), any Mac OS X and BSD filesystems, LVM2 volume management, MBR and GPT disk partitions, raw disks, qcow2, VirtualBox VDI, VMWare VMDK, Hyper-V VHD/VHDX, on files, local devices, CD and DVD ISOs, SD cards, or remotely over FTP, HTTP, SSH, iSCSI, NBD, GlusterFS, Ceph, Sheepdog, and much more.

Technical details of Netflix

Netflix uses a number of pieces of open-source software in its backend, including Java, MySQL, Gluster, Apache Tomcat, Hive, Chukwa, Cassandra and Hadoop.
