Part Number MCX653105A-HDAL MCX653106A-HDAL
Adapter IC Part Number MT28908A0-XCCF-HVM
ConnectX-6 Socket Direct™ Cards
The Socket Direct technology offers improved performance to dual-socket servers by enabling direct access from each CPU in a dual-socket server
to the network through its dedicated PCIe interface.
Please note that ConnectX-6 Socket Direct cards do not support Multi-Host functionality (i.e. connectivity to two independent CPUs). For
ConnectX-6 Socket Direct card with Multi-Host functionality, please contact NVIDIA.
ConnectX-6 Socket Direct cards are available in two configurations: Dual-slot Configuration (2x PCIe x16) and Single-slot Configuration (2x PCIe x8).

ConnectX-6 Dual-slot Socket Direct Cards (2x PCIe x16)

In order to obtain 200Gb/s speed, NVIDIA offers ConnectX-6 Socket Direct that enable 200Gb/s connectivity also for servers with PCIe Gen 3.0 capability.
The adapter's 32-lane PCIe bus is split into two 16-lane buses, with one bus accessible through a PCIe x16 edge connector and the other bus through an x16
Auxiliary PCIe Connection card. The two cards should be installed into two PCIe x16 slots and connected using two Cabline SA-II Plus harnesses, as shown in
the below figure.
