Product Description
NVIDIA Mellanox ConnectX-3 VPI MCX354A-FCBS is a dual-port network adapter featuring VPI (Virtual Protocol Interconnect) dual-protocol technology, enabling flexible switching between Ethernet and InfiniBand on the same physical card, with support for speeds up to 40/56G Ethernet / FDR (56G) InfiniBand delivered through a high-performance PCIe 3.0 x8 interface. This model features a Short Bracket design and hardware-offloaded RDMA technology (native IB RDMA and RoCE v1) to significantly reduce latency and CPU overhead in high-performance computing (HPC) and data center applications, making it ideal for enterprises and research institutions that need to deploy both Ethernet and InfiniBand architectures in the same facility, or that want the flexibility for future protocol transitions.
