Socket Direct network cards, which cost-effectively integrate a single network adapter silicon on a primary board, and an auxiliary PCIe connection card and
Cabline SA-II Plus Harness
connecting the two. Socket Direct enables direct access from each CPU to the network through its dedicated PCIe interface as the
card'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.
The PCIe auxiliary kit can be purchased separately to operate in a dual-socket server. The below table lists the available PCIe auxiliary kit ordering part
numbers, depending on the desired length of the

with a "WHITE" label while the harness is marked with a "BLACK" label.
The Cabline harness marked with the "WHITE" label should be connected to the connector on the networking card and PCIe Auxiliary card engraved with
"White Cable" while the one marked with the "BLACK" label should be connected to the connector on the networking card and the PCIe Auxiliary card
engraved with "Black Cable". The
