Product features

Multi-host technology

Innovative NVIDIA multi-most technology enables data centers to design and build scale-out heterogeneous compute and storage racks, with direct connectivity between compute elements and the network.

Overlay networks

In order to better scale networks, data center operators create overlay networks to encapsulate traffic from individual virtual machines over logical tunnels such as NVGRE and VXLAN. This solves network scalability issues, but places higher loads on the CPU. ConnectX-4 Lx offloads overlay networks from the CPU.

RDMA over converged Ethernet

ConnectX-4 Lx supports RoCE specifications delivering low-latency and high- performance over Ethernet networks. RoCE provides efficient low-latency RDMA services over layer 2 and layer 3 networks.
Key selling points
  • Hardware-based I/O virtualization
  • Multi-host technology
  • Connectivity to 4 independent hosts
  • Low latency RDMA over converged Ethernet
  • CPU offloading of transport operations
