Network Attached Storage (NAS) systems are computing storage devices that can

be accessed over the network. NAS enables multiple users to share the same storage
space simultaneously, and often minimizes overhead by managing hard disks
centrally. In terms of design, a NAS server is simply a file server optimized for file
system services.

                                    The Open-E NAS-XSR software provides the best combination of ease of management, scalability, reliability,
                                    availability, and performance for NAS systems. The Open-E NAS software is an optimized and tuned operating
                                    system, which turns a computer system into a NAS storage server in about 10 minutes. Pre-installation of the OS on
