The article discusses the distinction between NVMe storage and traditional hard disks, highlighting how many applications manage their own redundancy. It argues that for certain workloads, the focus should be on effective instance placement rather than unnecessary data replication. The piece also covers NVMe technology and the network architecture needed for distributed storage systems.

Optimizing network and storage configurations is crucial for efficient large-scale LLM training on the cloud, as these factors can significantly impact training speed and costs. Benchmarks show that using InfiniBand networking can achieve a 10x speedup over standard Ethernet, while selecting the right storage options can further enhance performance during training phases. The article discusses specific configurations and their implications for maximizing GPU utilization and minimizing bottlenecks.
