GlusterFS is a scalable network filesystem suitable for data-intensive tasks such as cloud storage and media streaming. GlusterFS is free and open source software and can utilize common off-the-shelf hardware. Gluster is a scalable, distributed file system that aggregates disk storage resources from multiple servers into a single global namespace. Enterprises can scale capacity, performance, and availability on demand, with no vendor lock-in, across on-premise, public cloud, and hybrid environments. Gluster is used in production at thousands of organisations spanning media, healthcare, government, education, web 2.0, and financial services. Scales to several petabytes, handles thousands of clients, POSIX compatible, uses commodity hardware, can use any ondisk filesystem that supports extended attributes, accessible using industry standard protocols like NFS and SMB, provides replication, quotas, geo-replication, snapshots and bitrot detection, and more.
