# Fault Tolerance
Dynamo provides comprehensive fault tolerance mechanisms to ensure reliable LLM inference in production deployments. This section covers the various strategies and features that enable Dynamo to handle failures gracefully and maintain service availability.
This document describes how Dynamo components handle shutdown signals to ensure in-flight requests complete successfully and resources are properly cleaned up.
This document describes the test infrastructure for validating Dynamo's fault tolerance mechanisms. The testing framework supports request cancellation, migration, etcd HA, and hardware fault injection scenarios.

# Disaggregated Serving Guide
[AIConfigurator](https://github.com/ai-dynamo/aiconfigurator/tree/main) is a performance optimization tool that helps you find the optimal configuration for deploying LLMs with Dynamo. It automatically determines the best number of prefill and decode workers, parallelism settings, and deployment parameters to meet your SLA targets while maximizing throughput.

# LoRA Adapters
LoRA (Low-Rank Adaptation) enables efficient fine-tuning and serving of specialized model variants without duplicating full model weights. Dynamo provides built-in support for dynamic LoRA adapter loading, caching, and inference routing.

# Multimodal Inference in Dynamo
Dynamo supports multimodal inference across multiple LLM backends, enabling models to process images, video, and audio alongside text. This section provides comprehensive documentation for deploying multimodal models.
This document provides a comprehensive guide for multimodal inference using SGLang backend in Dynamo. SGLang multimodal supports **EPD**, **E/PD**, and **E/P/D** flows, with NIXL (RDMA) for zero-copy tensor transfer in disaggregated modes.
Speculative decoding is an optimization technique that uses a smaller "draft" model to predict multiple tokens, which are then verified by the main model in parallel. This can significantly reduce latency for autoregressive generation.
[FlexKV](https://github.com/taco-project/FlexKV) is a scalable, distributed runtime for KV cache offloading developed by Tencent Cloud's TACO team in collaboration with the community. It acts as a unified KV caching layer for inference engines like SGLang, TensorRT-LLM, and vLLM.
This document explains how to implement KV event publishing for custom inference engines, enabling them to participate in Dynamo's KV cache-aware routing.
LMCache is a high-performance KV cache layer that supercharges LLM serving by enabling **prefill-once, reuse-everywhere** semantics. As described in the [official documentation](https://docs.lmcache.ai/index.html), LMCache lets LLMs prefill each text only once by storing the KV caches of all reusable texts, allowing reuse of KV caches for any reused text (not necessarily prefix) across any serving engine instance.
> ⚠️ **Experimental Feature**: ChReK is currently in **beta/preview**. The ChReK DaemonSet runs in privileged mode to perform CRIU operations. See [Limitations](#limitations) for details.
Checkpointing captures the complete state of a running worker pod (including GPU memory) and saves it to storage. New pods can restore from this checkpoint instead of performing a full cold start.
Don't have a Kubernetes cluster? No problem! You can set up a local development environment using Minikube. This guide walks through the set up of everything you need to run Dynamo Kubernetes Platform locally.
