Scale-out Network Attached Storage (NAS) refers to systems designed from the ground up for economically dynamic scale and support of extremely high-bandwidth applications. Scale-out NAS architectures have a number of cost advantages over scale-up products including low entry costs, higher utilization rates and ability to scale (without scaling headcount). This SearchStorage.com E-Guide provides an overview of the benefits of Scale-out storage and includes guidance on how to create an RFP when you are ready to invest in a NAS system.
