ConnectX-4 Single/Dual-Port Adapter supporting 100Gb/s with VPI

ConnectX-4 adapter with Virtual Protocol Interconnect (VPI), supporting EDR 100Gb/s InfiniBand and 100Gb/s Ethernet connectivity, provide the highest performance and most flexible solution for high-performance, Web2.0, Cloud, Data Analytics, Database, and Storage platforms.

With the exponential growth of data being shared and stored by applications and social networks, the need for high-speed and high performance compute and storage data centres is skyrocketing.

ConnectX-4 provides an unmatched combination of 100Gb/s bandwidth, sub microsecond latency ad 150 million messages per second. It includes native hardware support for RDMA over InfiniBand and Ethernet, Ethernet stateless offload engines, GPUDirect, and Mellanox's new Multi-Host Technology.

Multi-Host enables connecting multiple hosts into a single interconnect adapter by separating the ConenctX-4 PCIe interface into multiple and separate interfaces. Each interface can be connected to a separate host with no performance degradation. ConnectX-4 offers four fully-independent PCIe buses, lowering total cost of ownership in the data centre by reducing CAPEX requirements from four cables, NICs, and switch ports to only one of each, and by reducing OPEX by cutting down on switch port management and overall power usage.
