QM8700 InfiniBand Series

Quantum HDR 200Gb/s InfiniBand Smart Edge Switches

Faster servers, high-performance storage, and increasingly complex computational applications are driving data bandwidth requirements to new heights. NVIDIA QM8700 InfiniBand switches provide extremely high networking performance by delivering up to 16Tb/s of non-blocking bandwidth with extremely low latency. Static routing, adaptive routing, and advanced congestion management optimize computing efficiencies, making QM8700 ideal for top-of-rack leaf connectivity or for small to extremely large clusters.

High Bandwidth

High-performance computing (HPC) and AI environments need every last bit of the bandwidth delivered by NVIDIA high data rate (HDR) 200Gb/s switch systems. NVIDIA QM8700 switches provide up to 40 ports of 200Gb/s full bi-directional bandwidth per port. And novel NVIDIA HDR100 technology supports up to 80 ports of 100Gb/s, enabling HDR switches to provide double-density radix for 100Gb/s data speeds, reducing the cost of network design and network topologies.
