The clustered file system pools storage servers over TCP/IP or InfiniBand Remote Direct Memory Access (RDMA), aggregating disk and memory and facilitating the centralized management of data through a unified global namespace. The software works with low-cost commodity computers.
Use cases for GlusterFS include cloud computing, streaming media and content delivery. Scale-out storage systems based on GlusterFS are suitable for unstructured data such as documents, images, audio and video files, and log files.
Red Hat Inc. sponsors the Gluster open source community that develops GlusterFS and related software. The company supports a commercial version of GlusterFS, which ships with its Red Hat Storage Server product. In 2011, Red Hat acquired Gluster Inc., which worked on the development of GlusterFS and sold commercially supported options of the open source software.
