ConnectX-6 Dual-slot Socket Direct Cards 2x PCIe x16
In order to obtain 200Gb/s speed, Mellanox offers ConnectX-6 Socket Direct that enable
200Gb/s connectivity on
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.
