ConnectX-8擴展選項
有兩種可用的擴展選項：
對於900-9X81Q-00CN-ST0和900-9X81E-00EX-ST0：利用Socket-Direct/Multi-Host功能，其中PCIe擴展卡連接到SuperNIC，並作為端點使用。
對於900-9X81E-00EX-DT0：利用下游連接埠（DSP）選項，其中MCIO連接器用作儲存設備（GPU或SSD）的根復合體。
NVIDIA 提供 ConnectX-8 Socket Direct，該技術分別為具備 PCIe Gen5 或 Gen4 能力的伺服器提供 800Gb/s 或 400Gb/s 的連接速度。SuperNIC 的 32 通道 PCIe 總線被分為兩條 16 通道總線，其中一條總線可通過 PCIe x16 邊緣連接器訪問，另一條總線則通過 x16 輔助 PCIe 連接卡訪問。這兩張卡應分別安裝在兩個 PCIe x16 插槽中，並通過 MCIO 線束進行連接。
若要在Socket-Direct配置中使用SuperNIC，請訂購額外的PCIe輔助卡套件。支援Socket Direct的SuperNIC可以作為獨立的x16 PCIe卡使用。
