Description
The NVIDIA 900-9X81Q-00CN-ST0 is a ConnectX-8 C8240 SuperNIC with two QSFP112 ports, each supporting up to 400Gb/s. By default it runs two 400GbE Ethernet ports. It can also be configured as eight 100GbE ports or for NDR and XDR Lite InfiniBand. It connects over PCIe Gen6 at 64GT/s x16 and is compatible with Gen5. An optional additional PCIe x16 Gen5 link is available through an auxiliary card and MCIO harness, sold separately, for Socket Direct. Secure Boot and crypto are both enabled. The half-height, half-length card has PPS In/Out SMA connectors and SyncE timing, and ships with a tall bracket.
