What Gluster is

Gluster is a free, open-source distributed file system for Linux and self-hosted environments. It combines disk storage from multiple servers into one global namespace. The project describes it as scaling to several petabytes and serving thousands of clients. Gluster is POSIX compatible and can use on-disk filesystems that support extended attributes. Listed capabilities include replication, quotas, geo-replication, snapshots, and bitrot detection; access options include native GlusterFS, NFS, SMB/CIFS, iSCSI, and a Swift REST API. The project describes it as suitable for media streaming, data analysis, and other data- and bandwidth-intensive workloads. Capacity, performance, and availability can be scaled across on-premise, public cloud, and hybrid environments, and the software can be built using common off-the-shelf hardware. Installation resources include source downloads and Ubuntu PPAs. Documentation includes AWS deployment guidance, SSL information, and access-control-list administration. The project directs users seeking design or performance help to consultancies; Red Hat says it does not support community versions.
