46M2221 IBM Mellanox Connectx Dual Port PCI-E 2.0 4x

The IBM 46M2221 Mellanox Connectx Dual Port PCI-E 2.0 4x Ddr Infiniband Host Channel Adapter is a high-performance networking device that provides a low-latency, high-bandwidth connection between servers, storage systems, and other devices. It is based on the InfiniBand architecture, a high-speed interconnect technology that is used in high-performance computing, data centers, and other applications that require high-speed data transfer.

The device has two ports, each of which provides a maximum bandwidth of 40 Gb/s (20 Gb/s in each direction) and supports PCI Express 2.0 x8 host interface. It also supports Dual Data Rate (DDR) InfiniBand, a version of InfiniBand that uses double data rate signaling to provide higher bandwidth and lower latency.
