Description

The NVIDIA BlueField-3 B3140H SuperNIC is a single-port 400G network adapter for AI and HPC servers. It is designed for east-west traffic, moving data between GPUs and cluster nodes at high speed, and suits builders of AI server and cluster fabrics that need very high per-port bandwidth.

This SKU is the non-crypto B3140H variant with one 400G QSFP112 port and a PCIe Gen5 x16 host interface. Cisco lists the equivalent sibling card in its UCS C845A M8 AI server documentation for east-west networking, in a full-height, half-length form factor. A crypto-enabled B3140H variant exists under a separate part number, so confirm you need the non-crypto version when ordering.

The card needs a compatible 400G transceiver or cable for the QSFP112 port, which is sourced separately.

Enquire with XS Network Tech for new or used pricing and availability.
