• Backup, replication and large dataset transfers

Key specifications

• Interface: single 200 Gigabit Ethernet port
• Form factor: server PCIe network adapter
• Throughput: 200 Gbps line-rate capability on a single port
• Latency: optimized for low-latency packet processing
• Offload support: hardware acceleration for common networking tasks (checksum, segmentation, virtualization offloads)
• Compatibility: designed for integration with standard data center switches and fabrics
• Power and cooling: engineered for server-class thermal and power profiles

How to use

Install the BROADCOM NetXtreme N1200G into an available PCIe slot on a compatible server following the server vendor’s hardware installation guidelines. Connect the 200GbE link to the data center switch or fabric using appropriate optics or cables rated for 200Gb Ethernet. Install or update the operating system drivers and firmware provided by the adapter vendor to ensure full functionality and access to offload features. Configure network settings, VLANs and multipathing in the host OS or hypervisor according to your network design.

Usage recommendations

For optimal performance, pair the adapter with switches and transceivers certified for 200Gb Ethernet, keep firmware and drivers up to date, and verify server cooling and power headroom. When deploying in virtualized environments, enable supported offloads and use SR-IOV or other virtualization features to balance throughput and CPU utilization.
