NVIDIA Mellanox MTX6000-2SFS MetroDX 1km FDR10 Long-Haul InfiniBand Switch: This is a 32-port long-haul InfiniBand switch with 16 long-haul QSFP+ ports and 16 short-reach downlink QSFP+ ports, all operating at FDR10 (40 Gb/s per port). NVIDIA P/N 920-9B010-00FF-0M2. This is a professionally refurbished unit. It is NOT a short-reach top-of-rack data center switch and it does NOT support FDR (56 Gb/s), EDR (100 Gb/s), or HDR (200 Gb/s) InfiniBand speeds.
Engineering Context
Built on the MetroDX long-haul platform, the MTX6000-2SFS combines 16 long-haul QSFP+ ports for inter-site interconnect with 16 short-reach QSFP+ downlink ports for cluster aggregation. All 32 ports operate at FDR10 InfiniBand (40 Gb/s per port). The switch is fully managed and supports CLI and SNMP via the embedded management interface. It is RoHS6 compliant and ships with redundant AC power supplies. Airflow is configured PSU-side to connector-side (P2C). The MetroDX product family was designed to extend InfiniBand fabrics over dark fiber metro distances of up to 1 km without external repeater equipment.
Deployment and Use Cases
The MTX6000-2SFS is deployed for HPC site-to-site interconnection of geographically separated compute clusters within 1 km, disaster recovery replication of GPFS or Lustre storage between paired data centers, financial trading low-latency interconnects between metro-area facilities, and research network backbones bridging HPC labs across a campus. The 16 downlink ports enable local cluster aggregation while the 16 long-haul ports carry traffic to a paired site.
Technical Specifications
Model: MTX6000-2SFS
NVIDIA P/N: 920-9B010-00FF-0M2
Series: MetroDX Long-Haul
Total Ports: 32 (16 long-haul + 16 downlink)
Connector: QSFP+
Port Speed: FDR10 (40 Gb/s per port)
Reach: Up to 1 km on long-haul ports
Management: Fully managed (CLI, SNMP)
Power Supply: Redundant AC
Airflow: P2C (power-to-connector)

Condition: Refurbished
Compatibility and Hard Constraints
Long-haul ports require single-mode fiber and compatible long-reach QSFP+ optics (sourced separately). Downlink ports use standard QSFP+ DAC or AOC cables. The switch is compatible with Mellanox ConnectX-2 and ConnectX-3 HCA adapters at FDR10/QDR speeds via QSFP+. It does NOT support FDR (56 Gb/s), EDR (100 Gb/s), or HDR (200 Gb/s) speeds; QSFP28 cables negotiate down to FDR10. Long-haul reach beyond 1 km requires external repeater equipment not included with this switch. PSU and fan modules must share the same airflow direction.
