Use Case
The B3140L is the single-port 400GbE SuperNIC for a leaf-spine rack built on a 400G fabric: one QSFP112, 16GB of DDR5 for DOCA services, and an Arm subsystem that can host the vSwitch, firewall and NVMe-oF target on the NIC itself. It is the natural part for a server that needs one high-bandwidth uplink and wants the network services off the host cores.
