MQM8790-HS2F Together with the Mellanox ConnectX®-6 adapter card, a Mellanox Quantum switch supports the HDR100 protocol. By utilizing two pairs of two lanes per port, a Mellanox Quantum switch can support up to 80 ports of 100G to create the highest density Top-of-Rack (ToR) switch available in the market. This is a perfect solution for double density racks with more than 40 servers per rack, as it also relieves small-medium deployments from the need to scale to 3-level fat-tree, and provides savings on power, latency and space.

MQM8790-HS2F
Mellanox QM8700/QM8790 switch systems provide 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. These switches deliver 7.2 billion packets-per-second (Bpps), or 390 million pps per port. These systems are the industry’s most cost-effective building blocks for embedded systems and storage with a need for low port density systems. Whether looking at price-to-performance or energy-to-performance, these systems offer superior performance, power and space, reducing capital and operating expenses and providing the best return-on-investment.
MQM8790-HS2F
Powerful servers combined with high-performance storage and applications that use increasingly complex computations are causing data bandwidth requirements to spiral upward. As servers are deployed with next generation processors, High-Performance Computing (HPC) environments and Enterprise Data Centers (EDC) need every last bit of bandwidth delivered with Mellanox’s HDR InfiniBand systems.
