Description
The NVIDIA 900-9X81E-00EX-DT0 is a ConnectX-8 C8180 SuperNIC with a single OSFP cage. By default it runs one InfiniBand XDR 800Gb/s port. It can also be configured as two 400GbE ports, eight 100GbE ports, or NDR and XDR Lite InfiniBand options. It connects over PCIe Gen6 at 64GT/s x16 and is compatible with Gen5. This version adds an x16 PCIe downstream port (DSP) option, which connects to a server backplane or PCIe switch through an MCIO connector. That connection defaults to four x4 links for four SSDs and supports PCIe switch downstream port containment. 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. It is designed for data-center servers with adequate power and airflow, not desktops or workstations.
