ConnectX®-3 Pro Single/Dual-Port Adapter with Virtual Protocol Interconnect®

ConnectX-3 Pro adapter cards with Virtual Protocol Interconnect (VPI), supporting InfiniBand and Ethernet connectivity with hardware offload engines to Overlay Networks ("Tunneling"), provide the highest performing and most flexible interconnect solution for PCI Express Gen3 servers used in public and private clouds, enterprise data centers, and high performance computing.

Public and private cloud clustered databases, parallel processing, transactional services, and high-performance embedded I/O applications will achieve significant performance improvements resulting in reduced completion time and lower cost per operation. ConnectX-3 Pro with VPI also simplifies system development by serving multiple fabrics with one hardware design.


The Open Compute Project (OCP) mission is to develop and specify the most cost-efficient, energy-efficient and scalable enterprise and Web 2.0 data centers. Mellanox ConnectX-3 Pro VPI adapter card delivers leading InfiniBand and Ethernet connectivity for performance-driven server and storage applications in Web 2.0, Enterprise Data Centers and Cloud environments. The OCP Mezzanine adapter form factor is designed to mate into OCP servers.
