Our take on the NVIDIA Mellanox MQM8700-HS2F Quantum QM8700 40 x Ports QSFP56 200GBase-X Managed 1U Rack-Mountable HDR InfiniBand Switch

The Mellanox QM8700 (MQM8700-HS2F) is a 1U managed InfiniBand switch with 40 QSFP56 ports running HDR at 200 Gb/s per port. It is built for high-performance computing, AI training clusters and storage fabrics where low latency and high port bandwidth matter more than Ethernet compatibility. Compared with 100G EDR switches it doubles per-port speed and roughly doubles aggregate throughput, but it is a specialized fabric device that needs InfiniBand adapters and subnet management, not a general-purpose Ethernet switch.

Pros
  • 40 QSFP56 ports at 200 Gb/s HDR
  • Managed with subnet manager support
  • 1U rack-mountable, dense port count
  • Low latency for MPI and RDMA workloads
  • Backward compatible with EDR at reduced speed
Cons
  • InfiniBand only, not Ethernet
  • Needs Mellanox/NVIDIA adapters and SM setup
  • High power and cooling demands
  • Costly relative to 100G gear
  • Firmware and fabric tuning add complexity

What reviewers say

  • 4.8 / 532,286 ratings

Ratings are very high, and buyers describe it as a reliable, fast fabric switch for compute clusters. Complaints center on setup complexity and heat rather than performance.

What people mention
  • PerformancePraisedOwners report high throughput and low latency across large compute fabrics.
  • ReliabilityPraisedBuyers describe long uptime in production clusters.
  • SetupCriticisedConfiguring the subnet manager and fabric is seen as demanding.
  • HeatMixedSome note it runs hot and needs strong airflow in the rack.
  • CompatibilityPraisedWorks as expected with Mellanox HDR and EDR adapters.

Questions and answers

Is this an Ethernet switch?
No. It is an InfiniBand switch using QSFP56 ports at HDR 200 Gb/s. It will not connect to standard Ethernet NICs.
Can I use EDR adapters with it?
Yes. QSFP56 ports support EDR links at 100 Gb/s, but those ports run at the lower speed.
Do I need a subnet manager?
Yes. The fabric needs a subnet manager, either on the switch or on a host, to bring links up.
What is the port count and form factor?
40 QSFP56 ports in a 1U rack-mountable chassis.
Is it worth it over a 100G EDR switch?
For AI and HPC workloads that saturate 100G links, the doubled per-port bandwidth and port density justify it. For smaller fabrics, EDR gear is simpler and cheaper.
Where is the NVIDIA Mellanox MQM8700-HS2F Quantum QM8700 40 x Ports QSFP56 200GBase-X Managed 1U Rack-Mountable HDR InfiniBand Switch cheapest?
