How this unit is built

Built to your work order from a recovered chassis, with refurbished power supplies and fans for the airflow you need, then loaded with compatible firmware and operating system and tested before it ships.

Description

NVIDIA Mellanox MIS5024Q-1BRR InfiniScale IV 36-Port QDR InfiniBand Switch (1U, Unmanaged): This is a 1U short-depth InfiniBand switch based on the InfiniScale IV (IS4) ASIC, providing 36 QSFP ports of 40Gb/s QDR connectivity. The unit is unmanaged, ships with a single power supply, and uses connector-side to PSU-side (C2P) airflow. This is a refurbished QDR fabric switch — it is NOT FDR (56Gb/s) capable and is NOT a managed/subnet-manager-equipped variant. It is NOT an Ethernet switch; this SKU runs InfiniBand only.

Engineering Context. The MIS5024Q-1BRR is built around the InfiniScale IV switch silicon, delivering 2.88 Tb/s aggregate non-blocking QDR fabric throughput at 40Gb/s per port. Port-to-port latency is in the sub-200ns range typical of the IS4 generation. As an unmanaged switch, it carries no embedded subnet manager; the IB fabric requires an external SM (e.g., OpenSM on a host or a managed switch elsewhere).

Deployment & Use Cases. Common deployments include leaf positions in QDR HPC compute fabrics, storage interconnect for Lustre/GPFS clusters running on QDR, and lab/research fabrics where an external OpenSM host already exists. It is suitable as a hot spare or fleet replacement in environments still running QDR-class workloads.

Technical Specifications.

  • Model / MPN: MIS5024Q-1BRR
  • Switch ASIC: InfiniScale IV (IS4)
  • Form factor: 1U rack, short depth
  • Ports: 36 × QSFP
  • Per-port speed: 40Gb/s QDR InfiniBand
  • Aggregate throughput: 2.88 Tb/s non-blocking
  • Management: Unmanaged (no embedded subnet manager)
  • Power supply: 1 × AC PSU
  • Airflow: Connector side to PSU side (C2P / reverse)
  • FRUs: No field-replaceable units
  • Compliance: RoHS

Compatibility & Constraints. Works with NVIDIA Mellanox QDR/SDR ConnectX-2 HCAs and supports legacy DDR auto-negotiation. This is a QDR (40Gb/s) switch only — it is NOT FDR/EDR/HDR capable. As an unmanaged switch, an external subnet manager is required to bring up the fabric (managed variants like the -1SRR ship with embedded SM). Airflow is C2P (reverse) — verify rack airflow direction before installation. No FRUs means PSU and fans are not field-replaceable on this SKU.

Why TES. Sourced and bench-tested by T.E.S IT-SOLUTIONS. Each unit is functionally validated and shipped with technical support. Handling time 1–3 business days from our EU stock.
