Product Description
The NVIDIA Mellanox ConnectX-3 VPI MCX353A-FCBS is a single-port adapter supporting VPI (Virtual Protocol Interconnect) dual-protocol technology, allowing the same physical card to flexibly switch between Ethernet and InfiniBand, with speeds up to 40/56G Ethernet / FDR (56G) InfiniBand, delivered over a PCIe 3.0 x8 interface. This variant uses a short bracket design, and combined with hardware-offloaded RDMA (native InfiniBand RDMA and RoCE v1), significantly reduces latency and CPU overhead for high-performance computing (HPC) and data center applications — ideal for organizations and research institutions that need to deploy both Ethernet and InfiniBand fabrics in the same facility, or want the flexibility to switch protocols in the future.
