As llm serve more users and generate longer outputs, the growing memory demands of the Key-Value (KV) cache quickly exceed GPU capacity, creating a major bottleneck for large scale inference systems. In this talk, we discuss KV-cache storage offloading, a novel technique that enables inference acceleration by relocating attention cache data to high speed, low latency storage tiers. This approach alleviates GPU memory constraints and unlocks new levels of scalability for serving large models. We’ll dive deep into the architecture of inference workloads, explain the structure and role of the KV-cache, and walk through how storage offloading works in practice. Attendees will gain a clear understanding of: 1. Why external storage is increasingly essential for modern inference workloads 2. What the KV-cache is and why it becomes a bottleneck in large-scale deployments 3. How and when KV-cache storage offloading can improve inference performance
