Evolution of Data Center Design to Handle AI Workloads

Large Language Model (LLM) training differs significantly from traditional computing tasks, presenting unique challenges for data center design. This computationally intensive workload demands low latency, high throughput, and lossless network operations. We present an analysis of networking solutions designed to address these challenges in Artificial Intelligence (AI) focused data centers. Our approach leverages High Performance Computing tools and protocols, including Remote Direct Memory Access (RDMA), InfiniBand (IB), and Priority-based Flow Control (PFC). We examine high performance networking solutions such as RoCEv2, GPU Cluster Design, and Rail Optimized Design. These solutions effectively mitigate issues of packet loss and congestion, crucial for LLM training environments. Our analysis reveals potential challenges in implementing these solutions, providing valuable insights for optimizing data center operations in LLM training. This work contributes to the evolving field of AI infrastructure, offering a roadmap for researchers and practitioners developing next generation data centers for advanced AI applications.
