Introduction
The ThinkSystem Broadcom 57608 2x200/1x400GbE QSFP112 Ethernet Adapters are high-performance dual-port 200Gb Ethernet adapters with a PCIe 5.0 x16 host interface that are designed to build highly scalable, feature-rich networking solutions in servers for AI/ML, cloud, high-performance computing, and storage applications.
The 57608 Ethernet adapters are available in two form factors, a PCIe low-profile adapter and an OCP 3.0 adapter.
The adapters use the Broadcom BCM57608 400GbE MAC controller. Incorporating industry-leading PHY technology, the adapter provides highly efficient network connectivity using 8 lanes of built-in SerDes, each supporting 100/50G PAM-4 and 25G NRZ. The adapters support fourth-generation, standards-based RDMA over Converged Ethernet (RoCE) with hardware-based congestion control.
The 57608 Ethernet adapters offer two 200Gb Ethernet ports but can also be configured as a 1-port 400Gb adapter with port 1 active and port 2 disabled.
