About the Mellanox ConnectX
10/25/40/50 Gigabit Ethernet Adapter IC Supporting Mellanox Multi-Host®Technology, RDMA, Overlay Networks and more
ConnectX® -4 Lx EN Ethernet Network Controller with 10/25/40/50 Gb/s ports enables a cost-effective Ethernet connectivity for hyperscale and enterprise data centers, cloud infrastructures, and more, delivering best-in-class performance with smart multi-host offloading. ConnectX-4 Lx enables data centers to migrate from 10G to 25G and from 40G to 50G speeds at similar power consumption, cost, and infrastructure needs. With ConnectX-4 Lx, IT and applications managers can enjoy greater data speeds of 25G and 50G to handle today's growing demands for data analytics.
With the exponential increase in usage of data and the creation of new applications, the demand for the highest throughput, lowest latency, virtualization and sophisticated data acceleration engines continues to rise. ConnectX-4 Lx EN enables data centers to leverage a high-performance interconnect adapter for increasing operational efficiency, improving their servers' utilization and leveraging more from their applications, all while reducing total cost of ownership (TCO).
ConnectX-4 Lx EN provides a combination of 10, 25, 40, and 50GbE bandwidth, sub-microsecond latency and a 75 million packets per second message rate. It includes native hardware support for RDMA over Converged Ethernet, Ethernet stateless offload engines, Overlay Networks, GPUDirect® , and Mellanox Multi-Host technology.
Mellanox Multi-Host® technology enables the next generation scalable data center design to achieve maximum CAPEX and OPEX savings without compromising on network performance.
10G to 50G Ethernet Adapter
ConnectX-4 Lx EN offers a cost effective Ethernet adapter solution for 10, 25, 40, and 50 Gb/s Ethernet speeds, enabling seamless networking, clustering, or storage. The adapter reduces application runtime, and offers the flexibility and scalability to make infrastructure run as efficiently and productively as possible.
Mellanox Multi-Host®Technology
Mellanox's Multi-Host technology enables connecting multiple hosts into a single interconnect adapter by separating the ConnectX-4 Lx EN's PCIe interface into multiple and separate interfaces. Each interface can be connected to a separate host with no performance degradation. ConnectX-4 Lx EN offers four fully-independent PCIe buses, lowering total cost of ownership in the data center by reducing both CAPEX and OPEX. The technology reduces CAPEX requirements from four cables, four NICs, and four switch ports to only one of each, and reduces OPEX by cutting down on switch port management and overall power usage.
Each host can be active or inactive at any time, independent of the other hosts, and receives bandwidth of its own. Bandwidth is split between the hosts, either evenly (default) or based on configurable differentiated Quality of Service (QoS), depending on the data center's needs
