| Purpose | The EonStor DS 4000U Gen2 (Ultra 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. |
| Performance | Performance - up to 750K IOPS End-to-End, reading 11,000 MB/s, writing 5,500 MB/s. |
| Form factor | 3U, 19" rack mount, up to 16 drives |
| Controller(s) | Two controllers with redundancy and Multi-pathing (EonPath) support, Active-Active mode |
| Controller ports | Installed ports (per controller):
- 2 x 1Gb/s iSCSI ports (RJ-45)
- 2 x 12Gb/s SAS ports for connecting external expansion shelves
Per controller: 2 slots for Host Board cards, 4 DIMM slots, a compartment for Cache Backup Module (CBM), management ports, status indicators, control buttons
Additional ports when installing two Host Board type2 expansion cards (possible options, per controller):
