Network adapter broadcom hw N1400GD PCIe 5.0 x16, 400 Gigabit, QSFP112

Broadcom hw N1400GD is a PCIe 5.0 x16 network adapter that delivers 400 Gigabit connectivity through QSFP112 ports. Engineered for high-throughput server and data center environments, this adapter supports multi-rate 400 Gb/s links with low-latency packet handling and hardware offload capabilities. The card is intended to provide a reliable, high-bandwidth interface for backbone links, virtualization hosts and storage networks without introducing additional identifiers or manufacturer codes.

Advantages

The adapter provides a 400 Gigabit interface over QSFP112 physical ports and uses a PCIe 5.0 x16 host interface to maximize throughput. It is designed to minimize packet processing latency and to offer hardware offload functions that reduce CPU load for common network tasks. The form factor and interface are compatible with standard server PCIe slots and optimized for continuous, high-bandwidth operation in data center environments.

Suitable for (tasks / use cases)

• High-capacity backbone network links between switches and routers
• Virtualization hosts requiring high aggregate network throughput
• Storage networking and high-performance file transfer between servers
• High-performance computing clusters with intensive inter-node traffic
• Network function virtualization and software-defined networking deployments

Key specifications

• Interface: PCIe 5.0 x16 host connection
• Data rate: 400 Gigabit aggregate throughput
• Port type: QSFP112 physical ports for 400 Gb/s connectivity
• Performance characteristics: multi-rate 400 Gb/s support and low-latency packet processing
• Offload capabilities: hardware offload for common network tasks to reduce CPU utilization

How to use

Install the adapter into an available PCIe 5.0 x16 slot on a compatible server motherboard or chassis following standard hotplug and safety procedures where applicable. Connect QSFP112-compatible transceivers or direct-attach cables to the adapter ports and link them to the corresponding network equipment. Configure link parameters, drivers and firmware according to the server operating system and network management platform in use to enable full 400 Gb/s operation and offload features.

Usage recommendations

Use certified QSFP112 transceivers or cables and validated firmware/driver versions from the server or operating system vendor. Ensure adequate cooling and sufficient PCIe lane allocation in the server to sustain continuous 400 Gb/s throughput and to maintain low-latency performance.
