Clustered/scale-out NAS architectures stripe both data and metadata across multiple nodes to achieve scalability, load balancing, and fault tolerance. NAS devices connect to the network using the standard Ethernet protocol over TCP/IP, whereas SAN uses Fibre Channel or FCoE for connectivity. For serving content such as media files to network clients, NAS devices commonly implement UPnP (e.g., UPnP AV/DLNA) as a serving protocol. Block-based data storage, FCoE, and Fibre Channel protocol are all associated with SAN, not NAS, and therefore are not used.\n\n**Learn more:** [What is a clustered network-attached storage (NAS) system?](https://www.techtarget.com/searchstorage/definition/Clustered-network-attached-storage-clustered-NAS) · [What Is Network-Attached Storage (NAS)?
