NVIDIA Mellanox MCX512A-ACAT ConnectX-5 EN 25GbE SmartNIC

The MCX512A-ACAT dual-port network adapter?equipped with two 25G sfp28 ports, low latency (750ns), and supports up to 200 million messages per second (MPPs). For storage workloads, it provides a series of innovative acceleration functions, such as signature switching in hardware (t10-dif), embedded PCIe switch and fabric based NVME target unloading.

Connectx-5 adapter also brings advanced openvswitch unloading function to telecom and cloud data centers, which can drive extremely high packet rate and throughput while reducing CPU resource consumption, so as to improve the efficiency of data center infrastructure.

RDMA allows network traffic to bypass the CPU, avoids the use of TCP, and eliminates additional data copies to improve performance and free up the CPU core.
