The Broadcom® BCM957608-P1400GDF00 is a single-port 400 Gb/s PCI Express 5.0 x16 Network Interface Card that supports QSFP112-DD optical modules, DAC and AOC cables. 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 RoCE complexity deployment at scale. Based on Broadcom’s scalable 400G Ethernet controller architecture, the adapter is designed to build highly scalable, feature-rich networking solutions in servers for cloud, high-performance computing and storage applications.
