Description

High‑density 1U 200Gb/s HDR InfiniBand switch for AI/HPC leaf or spine deployments. Delivers line‑rate throughput with ultra‑low latency and advanced congestion control to maximize application performance. This configuration uses port‑side exhaust (P2C) airflow, includes dual hot‑swap PSUs and rack rails, and is the unmanaged variant requiring an external Subnet Manager (e.g., UFM or OpenSM).

Features

- 40x 200Gb/s HDR InfiniBand non‑blocking fabric
- Ultra‑low latency switching for AI/HPC workloads
- Unmanaged model for fabrics controlled by external SM (UFM/OpenSM)
- Advanced congestion control and adaptive routing
- Hot‑swap, redundant PSUs and fans
- Telemetry and counters for performance troubleshooting
- QSFP56 media flexibility: DAC, AOC, and optical modules
- 1U standard‑depth design with included rack rails

FAQs

Q: Is this a managed switch?
A: No. This QM8790 configuration is unmanaged and requires an external Subnet Manager such as UFM or OpenSM.

Q: What is the airflow direction?
A: P2C (Port‑to‑Cable) exhaust—air flows from the port side toward the PSU side.

Q: Does it include transceivers or cables?
A: No. Optics and cables are sold separately.

Q: Can it run Ethernet or RoCE?
A: No. This platform is InfiniBand‑only. Use with HDR‑class QSFP56 InfiniBand optics/DACs.

Q: Is a rail kit included?
A: Yes. A rack rail kit is included.

Q: Is it compatible with 100Gb/s devices?
A: Yes. With appropriate QSFP56-to-QSFP28 or splitter cables/transceivers, it can interoperate at reduced rates (e.g., HDR100/EDR).
