    2. Product Selection Features The most outstanding feature of the D8 Series is the expandable scalability. It enables small start and online expansion of the scalability. Not only the scalability within the unit (referred to as node) such as controller, cache and HDD, the D8 can expand its scalability by adding nodes. By this scalability, the D8 Series can cover a broad range from low-end area to high-end area.
