This section applies to the following adapter cards when used as Socket Direct cards in dual-socket servers.
Socket Direct network cards, which cost-effectively integrate a single network adapter silicon on a primary board, and an auxiliary PCIe connection card and Slim Line SAS harnesses 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 Cabline SA-II Plus harnesses.
|Ordering Part Number||Passive Auxiliary Connection||Cabline SA-II Plus Harnesses Length|
|MTMK9100-T15||PCIe Gen 4.0/5.0 x16 connection card||2x 150mm harnesses|
|MTMK9100-T25||PCIe Gen 4.0 x16 connection card||2x 250mm harnesses|
|MTMK9100-T35||PCIe Gen 4.0 x16 connection card||2x 350mm harnesses|
The two Cabline SA-II Plus harnesses in the PCIe auxiliary kit have different routings. To distinguish between these two harnesses, one black harness is marked 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 Cabline SA-II Plus harness mates with two 60-pin IPEX connectors (P/N 20790-060E-01), on both sides. The black Cabline SA-II Plus harness mates with the connector on the component side (top side) of the network card, while the White Cabline SA-II Plus harnesses mates with the pint side (bottom side) of the main network card. For hardware installation, please refer to ConnectX-7 Socket Direct (2x PCIe x16) Installation Instructions.
