ConnectX®-6 Single/Dual-Port Adapter ASIC Supporting 200Gb/s

The HDR ConnectX-6 adapter IC, the newest addition to the Mellanox Smart Interconnect suite and supporting Co-Design and In-Network Compute, brings new acceleration engines for maximizing High Performance, Machine Learning, Storage, Web 2.0, Cloud, Data Analytics and Telecommunications platforms.

ConnectX-6 with Virtual Protocol Interconnect® supports two ports of 200Gb/s InfiniBand (HDR) and Ethernet connectivity, sub-600 nanosecond latency, and 200 million messages per second, plus block-level encryption and NVMe over Fabric offloads, providing the highest performance and most flexible solution for the most demanding applications and markets.

Similar to previous generations, ConnectX-6 supports the Mellanox Multi-Host™ technology. Multi-Host enables multiple hosts to be connected into a single interconnect adapter by separating the PCIe interface into multiple and independent interfaces with no performance degradation. ConnectX-6 Multi-Host technology offers up-to eight (8) fully-independent PCIe buses, lowering total cost of ownership in the data center by reducing CAPEX requirements from multiple cables, NICs, and switch ports to only one of each, and by reducing OPEX by cutting down on switch port management and overall power usage.
