NVIDIA Mellanox MTX6100-2SFS MetroX 10km FDR10 Long-Haul InfiniBand Switch: This is a 1U long-haul InfiniBand switch with 6 QSFP+ ports operating at FDR10 (40 Gb/s per port) for reaches up to 10 km over single-mode fiber. NVIDIA P/N 920-9B010-00FF-0M4. This is a professionally refurbished unit. It is NOT a short-reach top-of-rack switch and it does NOT support FDR (56 Gb/s), EDR (100 Gb/s), or HDR (200 Gb/s) InfiniBand speeds.
Engineering Context
The MTX6100-2SFS extends InfiniBand fabrics over dark fiber up to 10 km without external repeater equipment. The 6 QSFP+ long-haul ports each operate at 40 Gb/s FDR10. The switch is fully managed and ships with the Mellanox network operating system, supporting CLI and SNMP for monitoring and configuration. A PowerPC PPC460 management processor runs the embedded software stack. The switch is housed in a 1U rack-mountable chassis with two AC power supplies for redundancy and P2C (power-to-connector) airflow. The unit is RoHS6 compliant.
Deployment and Use Cases
The MTX6100-2SFS is deployed for long-haul interconnect between geographically separated data centers up to 10 km apart, HPC site-to-site cluster federation, GPFS or Lustre storage replication across metro distances, financial low-latency cross-site links, and research backbones bridging multiple campus locations. The compact 6-port radix is designed for dedicated long-haul aggregation rather than dense local cluster switching.

Compatibility and Hard Constraints
The MTX6100-2SFS requires single-mode fiber and compatible long-reach QSFP+ optics for the 10 km reach (optics not included; verify compatibility before deployment). It is compatible with Mellanox ConnectX-2 and ConnectX-3 HCA adapters at FDR10/QDR via QSFP+ ports. It does NOT support FDR (56 Gb/s), EDR (100 Gb/s), or HDR (200 Gb/s) speeds; QSFP28 cables negotiate down to FDR10. It does NOT include long-reach optical transceivers. PSU and fan modules must share the same airflow direction.
