The Hitachi Network Attached Storage (HNAS) 4000 is a family of enterprise NAS systems that are offered along with the HNAS 3080 and HNAS 3090 systems. HNAS comes from Hitachi Data Systems acquisition of BlueArc and the 4000 is the second new generation since the acquisition. There are three models in the 4000 family that vary in underlying architecture of the FPGA hardware and number of interfaces and nodes. The HDS HNAS 4000 family consists of the 4100, 4080, and 4060 models.
The HNAS systems are also the NAS systems integrated with block storage controllers and storage devices to comprise the HUS and HUSVM systems for unified storage. The HUS and HUSVM systems are covered separate in the Evaluator Group ESR documents.
HDS ( and the predecessor for HNAS – BlueArc) has been a pioneer in bringing a custom-designed hardware platform NAS product into general usage for Information Technology. In addition, Hitachi also markets the HNAS systems into high performance computing environments and in the digital video space. The unique implementation coupled with the additional features has allowed HNAS to successfully address multiple usages in differing market segments.
