A distributed NAS system features flexible scalability, robust reliability, high performance, and ease of management.
i. Organizes massive nodes into a unified system and provides the capability to add and delete nodes.
ii. Instead of implementing data redundancy within a single node, distributed NAS stores data slices to disks of multiple nodes in a system, greatly improving reliability.
iii. Distributed NAS provides NAS services on each node to minimize the number of bottleneck points.
iv. In large-capacity scenarios, distributed NAS does not require multiple storage systems and it provides a unified management user interface, greatly improving maintainability.
