Interfaces Detailed Description
ConnectX-7 IC
The ConnectX-7 family of adapter IC devices delivers InfiniBand and Ethernet connectivity paired
with best-in-class hardware capabilities that accelerate and secure cloud and data-center
workloads.
PCI Express Interface
ConnectX-7 adapter cards support PCI Express Gen 5.0 (4.0 and 3.0 compatible) through x16 edge
connector. The following lists PCIe interface features:
PCIe Gen 5.0 compliant, 4.0, 3.0, 2.0 and 1.1 compatible
2.5, 5.0, 8.0, 16.0 and 32GT/s link rate x16/x32 (Socket-Direct configuration)
Support for PCIe bifurcation:Auto-negotiates to x32, x16, x8, x4, x2, or x1
NVIDIA Multi-Host™ supports connection of up to 4x hosts
Transaction layer packet (TLP) processing hints (TPH)
PCIe switch Downstream Port Containment (DPC)
Advanced error reporting (AER)
Access Control Service (ACS) for peer-to-peer secure communication
Process Address Space ID (PASID)
Address translation services (ATS)
Support for MSI/MSI-X mechanisms
Support for SR-IOV
Networking Interfaces
Protocol Specifications
Ethernet The network ports comply with the IEEE 802.3 Ethernet standards
listed in Features and Benefits. Ethernet traffic is transmitted through
the networking connectors on the adapter card.
InfiniBand The network ports are compliant with theInfiniBand Architecture
Specification, Release 1.5.InfiniBand traffic is transmitted through
the cards' networking connectors.
Networking Ports LEDs Specifications
There are two I/O LEDs per port to indicate port speed and link status.
LED1 is a bi-color LED (Yellow and Green)
The adapter card includes special circuits to protect from ESD shocks to the card/server
when plugging copper cables.
