Does it support virtualization features like SR-IOV?

Yes, the C8180 fully supports enterprise-grade virtualization features: SR-IOV, NVGRE, VXLAN, Geneve Offload, VirtIO-net/vDPA.

What are some typical use cases for the C8180?

It can be connected to 1.6T XDR optical modules and Quantum-X800 switches using XDR 800G modules.

Can the 800G port support NDR modules?

Yes, it can support NDR modules with 4 channels, each channel running at 100G.

For multiple servers, can one C8180 network card be used to connect them?

Yes, using the ST0 model (SocketDirect/Multi-Host) in conjunction with the C8180X auxiliary card allows you to split the PCIe x16 signal of the network card into 2 x8 signals, connecting them to the CPU slots of two motherboards.

Can the C8180 be used as a standard 2x400G Ethernet card?

Yes, the CX8 network card supports switching to 2x400GbE mode.

Questions & Answers

Ask a Question

What type of network card is the C8180? How does it differ from previous ConnectX series cards?

The C8180 is NVIDIA's first 800Gb/s dual-protocol SuperNIC for InfiniBand/Ethernet, belonging to the ConnectX-8 series. It is primarily designed for AI high-performance computing clusters, supercomputing networks, and next-generation data center architectures. It supports PCIe Gen6, features a new MCIO interface extension, and leans towards modularity, scalability, and multi-host/downstream direct connectivity.

What are the different models of the C8180? What are their distinctions?

The C8180 commonly comes in two models: 900-9X81E-00EX-ST0 supporting SocketDirect/Multi-Host, and 900-9X81E-00EX-DT0 supporting Downstream Port (DSP). Both use OSFP 800G interfaces but serve entirely different purposes in MCIO extension and are not interchangeable.

Does the C8180 support PCIe Gen5/Gen6? Is an auxiliary card necessary?

The main interface supports PCIe Gen5 and Gen6 x16, and you can optionally use the C8180X auxiliary card to achieve dual x16 (SocketDirect) or downstream expansion (DSP).
