Description
NVIDIA ConnectX-8 C8180 / C8180L 800G HHHL SuperNIC (900-9X81E-00EX-ST0)
NVIDIA ConnectX-8 C8180 / C8180L is a mass-production 800G-class HHHL SuperNIC family for AI, HPC, and accelerated data center networking. The adapters use a single OSFP cage and PCIe Gen6 x16 and support XDR 800Gb/s InfiniBand or 2x400GbE Ethernet, with multiple PCIe-extension and cooling options.
Availability / RFQ: NVIDIA currently documents this product family as being in mass production. Catalyst lists it for RFQ because exact board, system, support, quantity, and lead-time availability can vary by channel and deployment. Contact Catalyst Data Solutions to discuss current status, compatibility, configuration requirements, and sourcing options.Compliance notice: Sales and shipment may be subject to applicable U.S. export controls, destination screening, end-user/end-use requirements, and OEM/channel policies. Availability and eligibility must be verified before quotation or shipment.
