Network adapter BROADCOM NIC Broadcom P1400GD 400GbE PCIe5 x16 QSFP112-DD

BROADCOM NIC Broadcom P1400GD 400GbE PCIe5 x16 QSFP112-DD is a high-capacity network adapter engineered for server and data center environments that require a single 400GbE connection. With a PCIe Gen5 x16 host interface and one QSFP112-DD port, the adapter delivers low-latency, high-bandwidth networking suitable for virtualization, storage networking and high-performance computing workloads. The design supports efficient integration into modern server platforms while minimizing overhead and preserving system resources.

Advantages

This Broadcom P1400GD adapter provides a single 400GbE link through a QSFP112-DD port and uses a PCIe5 x16 interface for increased host throughput and reduced CPU overhead. It is designed to deliver consistent low-latency performance and high packet processing rates for demanding data center tasks. The compact single-port configuration simplifies cabling and port management while maintaining enterprise-grade reliability and compatibility with standard server platforms.

Suitable for

• High-performance computing clusters and distributed compute nodes
• Hyperconverged and virtualized environments requiring high throughput
• Storage area networks and NVMe-oF front-end or back-end connectivity
• High-density data center racks where a 400GbE uplink is required
• Network backbone aggregation and spine/leaf architectures

Key specifications

• Interface to host: PCI Express Gen5 x16
• External port: 1 × QSFP112-DD supporting 400GbE
• Throughput: single 400 Gigabit Ethernet link
• Form factor: low-profile server network adapter
• Designed for low latency and high packet-per-second performance

How to use

Install the Broadcom P1400GD into an available PCIe Gen5 x16 slot on a compatible server motherboard, secure the card in the chassis and connect a QSFP112-DD-compatible cable or transceiver to the external port. Ensure the server firmware and operating system include appropriate Broadcom drivers or firmware updates for the adapter to enable full performance and feature support. Configure network settings and link speeds through the operating system network tools or management software as required for the deployment.

Usage recommendations

Use high-quality QSFP112-DD cables or certified optical modules and verify that connected switches or transceivers support 400GbE. Maintain up-to-date drivers and firmware from Broadcom for optimal interoperability and performance. For virtualization or storage workloads, consider offloading and SR-IOV or RDMA features if supported in the environment to reduce CPU utilization.
