Mellanox InfiniScale IV QDR 8-Port QSFP InfiniBand Switch, Short Depth - 851-0167-01
This InfiniBand switch is the Mellanox 851-0167-01, an InfiniScale IV-based 8-port QDR InfiniBand switch in a short-depth form factor with an included power supply. This is a refurbished unit, professionally tested and validated by T.E.S IT-SOLUTIONS. It is NOT an FDR, EDR, or HDR InfiniBand switch. It supports QDR (40 Gb/s per port) only.
Engineering Context
The 851-0167-01 is built on the Mellanox InfiniScale IV switching ASIC, providing 8 QSFP ports each operating at 40 Gb/s QDR InfiniBand. The aggregate switching capacity is 640 Gb/s (full bisection bandwidth across all 8 ports). The switch is non-blocking at QDR speeds. Its short-depth form factor makes it suitable for shallow-depth racks and lab environments where standard 1U switches may not fit. The switch includes a single integrated power supply and is RoHS6 compliant.
Deployment and Use Cases
The 851-0167-01 is deployed as a small-scale InfiniBand QDR switch for lab clusters, development environments, proof-of-concept deployments, and edge connectivity in HPC test beds. With 8 ports, it can interconnect up to 8 QDR InfiniBand hosts for MPI-based parallel computing, storage testing, or RDMA development. It is also used as a secondary or satellite switch in larger QDR fabrics requiring additional leaf-tier port density in remote racks.
Technical Specifications

Compatibility and Hard Constraints
The 851-0167-01 uses QSFP connectors and requires QSFP InfiniBand cables rated for QDR speeds. It does NOT support FDR (56 Gb/s), EDR (100 Gb/s), or HDR (200 Gb/s) InfiniBand speeds. Higher-speed cables will negotiate down to QDR only. It does NOT support Ethernet protocols. It is compatible with Mellanox ConnectX-2, ConnectX-3, and ConnectX-3 Pro HCA adapters with QSFP ports. The short-depth form factor may not accept standard full-depth rack rails; verify rack depth before ordering.
