Open Compute Project
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-4 Lx EN OCP adapter cards deliver leading 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. ConnectX-4 Lx EN for Open Compute Project (OCP) improves network performance by increasing available bandwidth while decreasing the associated transport load on the CPU especially in virtualized server environments. Moreover, ConnectX-4 Lx EN introduces the new Multi-Host technology, which enables a new innovative rack design that achieves maximum CAPEX and OPEX savings without compromising on network performance.
