| Purpose | EonStor DS 4000 Gen2 (High Performance) systems deliver top-notch performance and unrivaled power in the small and medium business segment. With their unique controller module design that allows two different boards with additional interfaces for connecting to hosts (Host Board) and 12 Gb/s SAS interfaces for internal SAS drives and external connections, these systems provide enough throughput even for demanding applications such as multimedia editing. They are also extremely scalable and offer integrated advanced data services such as SSD Cache, automated storage and self-encrypting drives. |
