NVIDIA Mellanox MSX6036G-2SFS SwitchX-2 1U InfiniBand-to-Ethernet Gateway, 36-Port QSFP+, Dual AC PSU: This is a 1U managed gateway switch built on the SwitchX-2 ASIC, providing 36 QSFP+ ports that can operate as 56Gb/s FDR InfiniBand and/or 40Gb/s Ethernet, with the ability to bridge between InfiniBand and Ethernet fabrics. The 2SFS variant is the full-featured SKU with two redundant AC power supplies and standard-depth chassis. This is NOT a pure Ethernet-only switch and NOT a 100GbE Spectrum-class switch. Condition: Refurbished.
Engineering Context: The system uses the Mellanox SwitchX-2 ASIC (PPC460-class management CPU) to deliver up to 4.032 Tb/s aggregate bidirectional throughput across 36 QSFP+ ports running at 56Gb/s. As a gateway, it can transit traffic between native InfiniBand subnets and 40GbE Ethernet networks at line rate. Airflow on the standard variant is P2C (port-to-connector / front-to-rear). Two hot-swappable AC PSUs provide N+N power redundancy. The chassis is RoHS-6 compliant.
Deployment & Use Cases: Used as a fabric edge bridge in HPC clusters where compute nodes attach via FDR InfiniBand and need to reach 40GbE Ethernet storage, management, or WAN tiers without an external bridge. Common in MPI clusters, parallel file system gateways (Lustre/GPFS export to Ethernet), and university research data centers consolidating IB compute with Ethernet services on one switch.
Technical Specifications:
ASIC: Mellanox SwitchX-2
Form factor: 1U rack-mount, standard depth
Ports: 36 × QSFP+
Per-port speed: 56Gb/s FDR InfiniBand or 40GbE Ethernet
Aggregate bandwidth: up to 4.032 Tb/s bidirectional
Gateway function: InfiniBand ↔ 40GbE Ethernet bridging
Power: dual AC PSU (redundant, hot-swap)
Airflow: P2C (front-to-rear)
Management CPU: PPC460-class
Compliance: RoHS-6
Condition: Refurbished
Compatibility & Constraints: Compatible with QSFP+ DAC, AOC, and QSFP+ optical transceivers in either FDR / 56GbE or 40GbE modes. Pairs with ConnectX-3 / ConnectX-3 Pro VPI HCAs on the host side. This is a SwitchX-2 generation device — it is NOT capable of 100GbE / EDR / HDR rates and does NOT support Spectrum-only features. The gateway license enables IB-to-Ethernet bridging; verify firmware revision matches the gateway feature set before deployment. Software upgrade may be required to enable the latest features.
