Broadcom has begun sampling its third generation E-Series controller called Thor that brings the world's first 200G Ethernet controller with PCIe 4.0 and 50G PAM-4. It is designed for high performance computing, networking and storage applications including machine learning, storage disaggregation, and data analytics. 400G network connectivity will allow for more high-availability features and the 50G PAM-4 SerDes boosts performance and server efficiency. Companies that are adopting and integrating the technology include Lenovo, AMD, NVIDIA, Tencent, and more. "AMD intends to be an early adopter of PCIe 4.0 to meet the ever-increasing need for efficient, high-performance computing resources," said Raghu Nambiar, vice president of datacenter design engineering at AMD. "Broadcom is a valuable contributor to the technology ecosystem and AMD looks forward to the support for our CPU and GPU processor architectures from the Thor PCIe 4.0 product." "Broadcom's 200Gb Ethernet controllers continue to improve bandwidth on NVIDIA GPU-accelerated clusters, providing higher performance, and better scalability for HPC and deep learning applications," said Paresh Kharya, group product marketing manager for Accelerated Computing at NVIDIA. "With Broadcom's controllers supporting NVIDIA GPUDirect RDMA technology, data transfers between NVIDIA's data center GPUs can achieve higher bandwidth to address ever more complex and challenging scientific and industrial problems.
