Description

The BlueField-3 B3140H is a SuperNIC network adapter supplied under the Cisco part number UCSC-P-N3140H for UCS C-Series servers. It is built for data centre, AI and high-performance computing deployments where servers need very high bandwidth between the host and the network.

The adapter provides a single 400G QSFP112 port and connects to the server through a PCIe 5.0 x16 host interface. This pairing of one 400G port with a PCIe 5.0 x16 slot gives the card the host bandwidth needed to run the port at line rate, and it distinguishes this SKU from adapters with lower port speeds or narrower PCIe connections.
