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 sub-90ns port-to-port latency. 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 center devices to accelerate the communications frameworks using embedded hardware, resulting in an order of magnitude application performance improvements.
