Mellanox QM8700 Quantum HDR InfiniBand Datacentre Switch
Mellanox QM8700 HDR InfiniBand switch for high-performance computing and datacentre fabric interconnect.
The Mellanox QM8700 is a managed HDR InfiniBand switch designed for high-performance computing (HPC) clusters and datacentre fabric deployments. Operating at 200Gb/s per port HDR speeds, this switch provides the low-latency, high-bandwidth interconnect required for demanding computational workloads including AI training, machine learning inference, and scientific simulation environments.
The QM8700 forms part of Mellanox’s Quantum series switching platform, delivering 40 ports of HDR 200Gb/s InfiniBand connectivity in a 1U rack-mounted form factor. It is engineered for deployment in supercomputing clusters, enterprise HPC environments, and hyperscale datacentres where consistent sub-microsecond latency and non-blocking switching performance are critical requirements.
Following NVIDIA’s acquisition of Mellanox, the Quantum HDR platform continues to be supported within NVIDIA’s networking portfolio. The QM8700 remains a proven choice for organisations maintaining or expanding existing InfiniBand fabrics, offering backward compatibility with earlier InfiniBand generations whilst delivering next-generation HDR performance.
