We help you choose, configure, and deliver the right system — no obligation.
Configuration at a Glance
Tailored per engagement. Full technical overview below.
Overview
The Quantum QM8700 is a 1U managed HDR InfiniBand switch with 40 QSFP56 ports of 200Gb/s and an on-board subnet manager, ideal as a top-of-rack leaf for HDR and HDR100 clusters. Nexus Compute specifies, configures, and validates each QM8700 with the correct firmware and airflow, delivered warranty-backed through NVIDIA-authorized channels.
Who This Solution Is For
Business Benefits
Proven price-performance
Mature HDR 200G delivers low-latency RDMA at a lower cost-per-port than NDR for many HPC workloads.
Ultra-low latency
Sub-130ns port-to-port latency and 16 Tb/s non-blocking bandwidth keep tightly-coupled jobs efficient.
Configured and tested
Each switch is set up, validated, and sourced through authorized channels with full manufacturer warranty.
Typical Business Use Cases
Top-of-rack leaf for HDR clusters
HDR100 100G split-port connectivity
Low-latency HPC simulation interconnect
Storage and compute backbone for research
Industry Applications
Technical Overview
Built on the NVIDIA Quantum HDR ASIC, the QM8700 provides 40 ports of 200Gb/s on QSFP56 (or up to 80 ports of HDR100 100Gb/s) with 16 Tb/s of non-blocking throughput and sub-130ns latency. An onboard subnet manager and MLNX-OS deliver complete chassis and fabric management for small-to-large clusters.

Frequently Asked Questions
Is HDR 200G still a good choice versus NDR 400G?
Yes for many HPC and mid-scale AI workloads, HDR delivers excellent low-latency price-performance; NDR 400G is warranted when per-GPU bandwidth or very large fat-trees demand it. We advise based on workload and budget.
How many nodes can a QM8700 connect?
With 40 HDR ports (or 80 HDR100 ports via splitter cables) it serves as a dense top-of-rack leaf; we size leaf and spine counts to your node count and oversubscription target.
Does the QM8700 need an external subnet manager?
No, it includes an onboard subnet manager for self-contained fabrics; larger multi-switch deployments can still be centrally managed with NVIDIA UFM.
