Gluster delivers an open storage software platform focused on simplifying the task of storing and managing the explosive growth of unstructured data. Our scale-out storage platform runs on commodity hardware scaling out in building block fashion from a few terabytes to multiple petabytes to meet the most demanding capacity and performance needs at a fraction of the cost of traditional systems. Gluster uses a unified global namespace to virtualize disk and memory resources into a single shared pool that is centrally managed. Our scalable virtual NAS appliances address the needs of traditional data centers, shared storage for VM environments, and both public and private storage clouds.
