Description

Ultra‑low‑latency 1U HDR InfiniBand switch for dense AI/HPC fabrics. The QM8790 unmanaged variant delivers non‑blocking 200Gb/s per port and advanced IB congestion control while relying on an external Subnet Manager (UFM/OpenSM). This configuration uses C2P airflow, includes 2x hot‑swap PSUs, and ships with rails.

Features

- 40x line‑rate 200Gb/s HDR IB ports
- External‑managed design for large fabrics (UFM/OpenSM)
- Low‑latency switching optimized for AI/HPC workloads
- Advanced congestion management and adaptive routing
- Redundant hot‑swappable PSUs and fans
- QSFP56 media flexibility (DAC/AOC/optics)
- 1U standard‑depth chassis with included rails
- Telemetry counters for fabric visibility

FAQs

Q: Is a Subnet Manager built in?
A: No. This unmanaged model requires an external SM (UFM or OpenSM).

Q: What is the airflow orientation?
A: C2P (Cable‑to‑Port) intake—air flows from the PSU side toward the port side.

Q: Are cables or transceivers included?
A: No. They are sold separately.

Q: Does it support 100Gb/s links?
A: Yes, with suitable breakout or adapter cables/transceivers at reduced rates (e.g., HDR100/EDR).

Q: Can this be used in Ethernet networks?
A: No. It is an InfiniBand‑only platform.
