Overview
Product overview
The NVIDIA ConnectX-6 MCX653106A-HDAT is a high-performance, dual-port smart adapter card engineered to accelerate the most demanding data centers. As a cornerstone of the NVIDIA Quantum InfiniBand platform, this network interface card provides two QSFP56 ports, each capable of 200Gb/s InfiniBand HDR or Ethernet connectivity. Its defining innovation is In-Network Computing, which transforms the network card from a passive data pipe into an active compute element, offloading operations from the CPU to boost application performance and scalability for High-Performance Computing (HPC), Artificial Intelligence (AI), and hyperscale cloud infrastructures. Extreme Performance: Delivers up to 200Gb/s per port (400Gb/s aggregate) with ultra-low latency and up to 215 million messages per second In-Network Computing: Revolutionary technology offloads computation and memory access to dramatically increase system efficiency
