Anyscale has introduced a new fault tolerance feature for its vLLM serving engine, integrated with Ray Serve. This enhancement specifically addresses the challenges of deploying large Mixture-of-Experts (MoE) models, which are sharded across multiple GPUs. The new system can now identify and restart entire groups of GPUs that form a data-parallel (DP) group when a single GPU within that group fails, preventing the entire deployment from becoming unavailable.
