What are Scale-out File Systems

Scale-out File Systems or SoFS for short are large-scale file serving implementations in software.  Distinguishing Scale-out File Systems from standard Network Attached Storage (NAS) is the large scale in the number of nodes supported, the amount of capacity, and number of files as well as being offered as software for subsequent integration on a variety of hardware systems.  Some of the Scale-out File Systems are also distinguished in their offering of parallel transfer to a file using POSIX compliant clients.  Scale-out File Systems implementations are similar to scale out NAS systems but with those different characteristics.  In general, the number of nodes is over a thousand, the capacity is practically unlimited, and the number of files is in the billions.  The number of parallel operations possible is usually relative to the number of nodes.
