Product Description
The NVIDIA Mellanox ConnectX-6 MCX653106A-HDAT is a dual-port Virtual Protocol Interconnect (VPI) adapter card that provides two independent 200Gb/s ports of InfiniBand HDR or Ethernet connectivity through QSFP56 connectors and a PCIe 4.0 x16 host interface. Built on the MT28908A0-XCCF-HVM controller, it shares the same sub-600ns latency and up to 200 million messages per second performance envelope as its single-port sibling, while the second port enables fabric redundancy, dual-rail bandwidth aggregation, or independent connections to separate InfiniBand and Ethernet fabrics. Hardware-accelerated RDMA/RoCE v2, NVIDIA PeerDirect (GPUDirect) for GPU-to-NIC transfers, SR-IOV, and in-network computing offloads make it well suited to bandwidth-hungry AI training clusters, HPC simulation, and converged storage/compute fabrics that require high-availability connectivity. Distributed by MABLETECH for regional system integrators and data center customers.
