Interfacekaart Broadcom BCM957504-N1100G PCIe QSFP56

The Broadcom BCM957504-N1100G Interface Card is an internal PCIe adapter with a single 100G QSFP56 port designed for server networking and storage applications. Based on Broadcom's scalable NetXtreme-E architecture, this PCIe card combines a high-bandwidth Ethernet controller with hardware acceleration engines to improve throughput and reduce CPU load in data center, cloud and telco environments. The card uses passive cooling and includes LED indicators for activity and link status.

Advantages

The BCM957504-N1100G delivers high throughput and advanced flow processing through on-chip acceleration technologies, enabling up to a 5× increase in tunneling protocol throughput (Geneve, VXLAN, NVGRE) and significant reductions in CPU utilization versus software-only solutions. TruFlow hardware acceleration can increase virtual machine density by up to 50%, freeing CPU cycles for additional workloads. The adapter also supports advanced networking features such as RoCE, SDN and NFV, making it suitable for modern data center and cloud deployments.

Suitable for

• High-performance computing clusters and enterprise servers
• Cloud and hyperscale data centers
• Telco and edge networking equipment
• NVMe-oF storage and storage disaggregation
