Description

Built with Quantum InfiniBand switch device, Mellanox MQM8790-HS2F provides 40x HDR 200G QSFP56 ports, and each QSFP56 port can be configured as 2x HDR100 100G via breakout cables. The switch provides the highest performing fabric solution in a 1U form factor by delivering up to 16Tb/s of non-blocking bandwidth with sub 130ns port-to-port latency. MQM8790-HS2F enables efficient computing with features such as static routing, adaptive routing, congestion control and enhanced VL mapping to enable modern topologies (SlimFly, Dragonfly+, 6DT). These ensure the maximum effective fabric bandwidth by eliminating congestion hot spots.
