NEC HYDRAstor
NEC HYDRAstor is a disk-based grid storage system with data deduplication for backups and archiving, developed by NEC Corporation. A HYDRAstor storage system can be composed of multiple nodes, starting from one up to 100+ nodes. Each node contains standard hardware including disk drives, CPU, memory and network interfaces and is integrated with the HYDRAstor software into a single storage pool. HYDRAstor software incorporates multiple features of distributed storage systems: content-addressable storage, global data deduplication, variable block size, Rabin fingerprinting, erasure codes, data encryption and load balancing.
