Description
The Broadcom BCM957608-N1400GDP00 is a high-performance, single-port 400GbE QSFP-DD OCP 3.0 network adapter built for next-generation AI/ML, cloud, hyperscale, and HPC server environments. Designed around Broadcom’s advanced 400G Ethernet controller architecture, this adapter delivers exceptional throughput, low latency, and efficient flow processing—optimizing performance for modern data-intensive workloads.
Equipped with PCIe Gen5 x16, it enables extremely high host-to-network bandwidth. Its QSFP-DD interface supports multiple link speeds including 400/200/100/50/25GbE, powered by 8 SerDes lanes capable of 100G PAM4 and 25G NRZ signaling. Hardware-accelerated features such as TruFlow™ flow processing, congestion-controlled RoCEv2, tunnel offloads, and encryption acceleration (kTLS/QUIC) ensure scalable and secure deployment across complex infrastructures.
With advanced platform security—including secure boot, attestation, OCP Secure Recovery, and Silicon Root of Trust—the BCM957608-N1400GDP00 provides robust protection for mission-critical server platforms. It is ideal for GPU clusters, NVMe disaggregation, virtualized environments, and next-generation cloud compute architectures.
