O Virtualiza
tion
ConnectX-5 provides dedicated adapter resources and guaranteed isolation and protection for
virtual machines within the server.
Storage
Acceleratio
n A consolidated compute and storage network achieves significant cost-performance advantages
over multi-fabric networks. Standard block and file access protocols can leverage RDMA for
high-performance storage access.
• NVMe over Fabric offloads for target machine
SR-IOV ConnectX-5 SR-IOV technology provides dedicated adapter resources and guaranteed isolation
and protection for virtual machines (VM) within the server.
NC-SI over

Host
Managemen
t
Technology NVIDIA’s host management technology for standard and multi-host platforms optimizes board
management and power, performance and firmware update management via NC-SI, MCTP over
SMBus and MCTP over PCIe, as well as PLDM for Monitor and Control DSP0248 and PLDM for
Firmware Update DSP0267.
Multi-Host
Technology
NVIDIA Multi-Host™ technology, when enabled, allows multiple hosts to be connected into a
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 powered by a shared buffer architecture, connection-tracking offloads, and RoCE
enhancements, ConnectX-5 offers an extremely flexible solution for today’s demanding data
center and cloud application.
NVIDIA
Socket
Direct
™
NVIDIA Socket Direct technology brings improved performance to multi-socket servers by
enabling direct access from each CPU in a multi-socket server to the network through its
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.
