Product Description
The NVIDIA Mellanox ConnectX-4 VPI MCX445B-ECAN is a single-port 100Gb/s Virtual Protocol Interconnect (VPI) adapter in the Open Compute Project (OCP) 2.0 mezzanine form factor, capable of operating as either 100Gb/s EDR InfiniBand or 100 Gigabit Ethernet on the same QSFP28 port, field-selectable per deployment. It connects to the host through a PCIe 3.0 x16 interface and supports native InfiniBand RDMA transport as well as RDMA over Converged Ethernet (RoCE v2) when configured for Ethernet mode, giving system integrators flexibility to standardize on a single adapter SKU across both HPC/InfiniBand fabrics and Ethernet-based cloud/enterprise networks. As an OCP 2.0 mezzanine card, the MCX445B-ECAN is designed for tool-less installation in OCP-compliant chassis. Distributor records for this SKU do not list a specific controller revision or NVIDIA ordering part number; buyers should confirm exact firmware/controller revision and current NVIDIA SKU with MABLETECH or an NVIDIA channel partner prior to order.
