Scale-out NAS (Network Attached Storage) is a storage architecture that allows for seamless scalability by adding more nodes to the system. Each node provides additional storage capacity and processing power, enabling the system to grow linearly and handle increasing amounts of data without performance degradation. Unlike traditional NAS, which might be limited by the capacity and performance of a single appliance, scale-out NAS distributes data across multiple nodes, enhancing redundancy, availability, and load balancing. This architecture is ideal for environments with rapidly growing data needs, such as big data analytics, content repositories, and cloud storage solutions.

How Scale Out NAS Works
Scale-Out NAS operates through a distributed architecture where data is stored across multiple interconnected storage nodes. These nodes work together to provide a unified storage pool, presenting a single namespace to clients. When data is stored, it is divided into smaller chunks or objects and distributed across these nodes, ensuring load balancing and redundancy. This distributed approach enables parallel access to data, enhancing performance and scalability. As the storage needs grow, additional nodes can be seamlessly added to the cluster, expanding capacity and performance without downtime.
