FusionNAS is a clustered storage system for large amounts of data. It can use an x86 server as a storage unit, and provides a global interface compatible with a native disk-access interface.

The FusionNAS storage system provides PB-level capacity and can be increased online based on requirements. Using a metadata server clustering technique, while removing the limits of current file systems, FusionNAS provides nearly unlimited file storage amounts and fast file indexing. It can store 10 million files while still delivering a fast file-indexing speed. Meanwhile, FusionNAS provides high availability for the whole system, avoids single-node failure issues, and provides fault detection and fast data recovery.
