40-port Non-blocking Externally Managed HDR 200Gb/s InfiniBand Smart Switch

Mellanox provides the world's smartest switch, enabling in-network computing through the Co-Design Scalable Hierarchical Aggregation and Reduction Protocol (SHARP) technology. QM8790 has the highest fabric performance available in the market with up to 16Tb/s of non-blocking bandwidth with sun-90ns port-to-port latency.

Scaling-out data centres with HDR 200G InfiniBand

Faster 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 Centres (EDC) will need every last bit of bandwidth delivered with Mellanox's next generation of HDR InfiniBand, high-speed, smart-switches.

World's Smartest Switch

Built with Mellanox's Quantum InfiniBand switch device, the QM8790 provides up to forty 200Gb/s ports, with full bi-directional bandwidth per port. These stand-alone switches are an ideal choice for top-of-rack leaf connectivity or for building small to extremely large sized clusters.

QM8790 is the world's smartest network switch, designed to enable in-network computing through the Co-Design Scalable Hierarchical Aggregation and Reduction Protocol (SHARP) technology. The Co-Design architecture enables the usage of all active data centre devices to accelerate the communications frameworks using embedded hardware, resulting in an order of magnitude application performance improvements.

QM8790 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.

The QM8790 switch has best-in-class design to support low power consumption. Power is further reduced upon partial port utilisation.

Collective communication acceleration

Collective communication describes communication patterns in which all members of a group of communication endpoints participate. Collective communications are commonly used in HPC protocols such as MPI and SHMEM.

The Quantum switch improves the performance of selected collective operations by processing the data as it traverses the network, eliminating the need to send data multiple times between endpoints.

It also supports the aggregation of large data vectors at wire speed to enable MPI large vector reduction operations, which are crucial for machine learning applications.

HDR100

QM8790 together with the Mellanox ConnectX-6 adapter card support HDR100. By utilising two pairs of two lanes per port, the QM8790 can support up to 80 ports of 100G to create the densest TOR switch available in the market. This is a perfect solution for double dense racks with more than 40 servers per rack and also helps small-medium deployments with the need to scale to 3-level fat-tree, to lower power, latency and space.

Building Efficient Clusters

QM8790 is the industry's most cost-effective building block for deploying high performance clusters and data centres. Whether looking at price-to-performance or energy-to-performance, QM8790 offers superior performance, low power and scale, reducing capital and operating expenses, and providing the best return-on-investment.
