Red Hat Storage is a new distributed file system (DFS ) based on the Gluster file system.
Red Hat first introduced the feature, also called Red Hat Storage Server for On-premise, in Red Hat Enterprise Virtualization (RHEV) 3.1.

A distributed file system is a client/server-based application that allows clients to access and process data stored on the server as if it were on their own computer. Red Hat Storage acts as a scale-out network-attached storage (NAS) and object storage software solution.

Other benefits of Red Hat Storage:
• Eliminates the need for proprietary storage systems.
• Offers scalable storage in the data center or on-premise private cloud.
• Enables the addition of compute, I/O bandwidth and storage resources as needed to meet capacity and performance needs without reconfiguring the storage layer.
• Files are presented as one file system structure independent of the underlying physical storage location.
• Storage can be configured in a variety of ways.
• Redundancy is built-in.
