Feature

Multi-Host

NVIDIA Multi-Host™ technology, when enabled, allows multiple hosts to be connected into a

Technology

single adapter by separating the PCIe interface into multiple and independent interfaces. By

Using NVIDIA Multi Host™, ConnectX-5 lowers the total cost of ownership (TCO) in the data center

by reducing CAPEX (cables, NICs, and switch port expenses), and by reducing OPEX by cutting

down on switch port management and overall power usage. With NVIDIA Multi-Host™ technology

ConnectX-5 offers an extremely flexible solution for today's demanding data center and cloud

application.

NVIDIA

NVIDIA Socket Direct technology brings improved performance to multi-socket servers by

Socket

enabling direct access from each CPU in a multi-socket server to the network through its

Direct™

dedicated PCIe interface. With this type of configuration, each CPU connects directly to the

network; this enables the interconnect to bypass a QPI (UPI) and the other CPU, optimizing

performance and improving latency. CPU utilization improves as each CPU handles only its own

traffic, and not the traffic from the other CPU. NVIDIA's OCP 3.0 cards include native support for

socket direct technology for multi-socket servers and can support up to 4 CPU sockets.
