Description

NVIDIA Mellanox MIS5025Q-1BFC InfiniScale IV QDR InfiniBand Switch — 36 QSFP Ports, 40Gb/s per Port, 1U, Single PSU: This is an unmanaged 36-port InfiniScale IV QDR InfiniBand switch with QSFP cages, in a 1U rack form factor. The "1BFC" suffix designates a single power supply with PSU-side to connector-side (P2C / front-to-back) airflow. This is NOT a managed switch with onboard subnet manager and NOT an FDR or EDR-class platform — it is QDR (40Gb/s per port). Condition: New (unused, original packaging where available).

Engineering Context: The MIS5025Q-1BFC is built on the InfiniScale IV ASIC, providing non-blocking 2.88Tb/s switching capacity across 36 QSFP ports, each operating at QDR (4x10Gb/s) for 40Gb/s aggregate per port. As an unmanaged switch, fabric subnet management must be supplied by an external OpenSM instance running on a connected host or a managed peer switch.

Deployment & Use Cases: Used as a top-of-rack or aggregation switch in QDR InfiniBand HPC clusters, legacy research-lab compute fabrics, low-cost MPI back-end networks, and as a cost-effective option for extending or rebuilding existing QDR-class clusters where FDR/EDR upgrade is not yet justified.

Technical Specifications:

  • Switch Family: InfiniScale IV
  • Port Count: 36 x QSFP
  • Per-Port Rate: QDR InfiniBand 40Gb/s (4x10Gb/s)
  • Switching Capacity: 2.88 Tb/s aggregate, non-blocking
  • Management: Unmanaged (external OpenSM required)
  • Form Factor: 1U rack-mount
  • Power Supply: Single PSU (1xPSU)
  • Airflow: PSU-side to connector-side (P2C, front-to-back)
  • Chassis Depth: Standard short-depth
  • Condition: New

Compatibility & Constraints: Compatible with Mellanox ConnectX-2 / ConnectX-3 QDR HCAs and any QSFP QDR-capable adapter, plus Mellanox QSFP DDR/QDR copper and active optical cables. NOT compatible with FDR (56Gb/s) or EDR (100Gb/s) line-rate operation — links to FDR/EDR adapters will negotiate down to QDR. Requires external OpenSM for fabric initialization. Single PSU (no power redundancy in this 1BFC variant).

Frequently Asked Questions

What is the MIS5025Q-1BFC NOT compatible with?

This is NOT a managed switch with onboard subnet manager and NOT an FDR or EDR-class platform — it is QDR (40Gb/s per port). Confirm fitment against your platform before ordering MIS5025Q-1BFC.

What condition is the MIS5025Q-1BFC supplied in, and who sells it?

The MIS5025Q-1BFC is supplied in New condition by T.E.S IT-SOLUTIONS from EU stock, with 1-3 business day handling and worldwide B2B shipping. See https://www.tes-itsolutions.com/product-page/new-mellanox-mis5025q-1bfc-infiniband-switch-36x-qsfp-40gbps-ports-1xpsu.

Are there deployment constraints on the MIS5025Q-1BFC?

NOT compatible with FDR (56Gb/s) or EDR (100Gb/s) line-rate operation — links to FDR/EDR adapters will negotiate down to QDR. This applies to MIS5025Q-1BFC specifically.
