NVIDIA BlueField-3 E-Series B3140H 400G QSFP112

This NVIDIA BlueField-3 E-Series B3140H is a network adapter built on a PCI Express 5.0 x16 interface. It provides a single 400 Gigabit QSFP112 port for high-throughput data centre fabrics. The card targets infrastructure teams deploying accelerated networking and storage offload.

Suited for single-port 400G deployments on PCIe

This adapter fits servers that can supply a full PCIe 5.0 x16 connection and need one 400 Gigabit QSFP112 link. Buyers who require multiple ports on a single bracket or a different physical connector should evaluate other form factors. Systems limited to PCIe 4.0 or narrower lane widths cannot utilise the full interface bandwidth.

Deciding spec: PCI Express 5.0 x16

The single specification that determines fit is the PCI Express 5.0 x16 interface paired with one 400 Gigabit QSFP112 port. Verify the host platform supports PCIe 5.0 x16 electrically and mechanically and that the switch or peer device matches the 400G QSFP112 media. Without that alignment the card cannot operate at its rated link speed.

Questions about this item

Does the BlueField-3 E-Series B3140H ship with the QSFP112 transceiver or must I buy it separately?

The card has one 400 Gigabit QSFP112 port; transceivers and cables are not included and must be sourced separately.

The listing shows a single 400 Gigabit QSFP112 port — are there other port-count or speed versions of the B3140H?

This part number provides exactly one 400 Gigabit QSFP112 port; no other port configurations exist for the B3140H model.

What throughput can I expect from the PCIe 5.0 x16 interface when the card runs at its rated 400 Gigabit line rate?

PCIe 5.0 x16 supplies enough bandwidth to sustain the full 400 Gigabit Ethernet line rate without bottleneck.
