Broadcom Dual-Port 200 Gb/s QSFP PCI Express 5.0 x16 Ethernet Network Interface Card

General Description

Based on Broadcom’s scalable 400G Ethernet controller

architecture, the BCM957608-P2200GQF00 2 x 200G PCIe

NIC is designed to build large scale, feature-rich networking

solutions in servers for AI/ML, cloud, high-performance

computing, and storage applications.

The BCM957608-P2200GQF00 PCIe NIC builds upon the

success of the widely deployed Broadcom architecture by

combining a high-bandwidth Ethernet controller with a

unique set of highly optimized hardware acceleration

engines to enhance network performance and improve

server efficiency.

The adapter supports fourth-generation, standards-based

RDMA over Converged Ethernet (RoCE) with hardware-

based congestion control. Broadcom’s RoCE congestion

control delivers the lowest latency in real-life scenarios and

dramatically reduces the complexity of RoCE deployment at

scale.

The BCM957608-P2200GQF00 adapter addresses the

performance requirements of mega-scale data center

networks with high throughput and advanced flow

processing offloads. Features such as TruFlow™ increase

virtual machine density by freeing up CPU cycles. The

adapter supports technology-leading security enabling the

industry’s most secure server platform with secure boot and

attestation anchored in Broadcom’s silicon root of trust

(RoT).
