Huawei Debuts OceanStor M900 Context Memory Storage: PB-Scale Shared KV Cache With ~60μs NPU-to-SSD Hop

Huawei introduced the OceanStor M900 storage system at HUAWEI CONNECT 2026 in Shanghai on September 17, designed specifically for AI inference rather than as another accelerator card. The system features a multi-tier KV-cache memory, allowing a single cluster to reach 64 PB of capacity, enhancing memory reuse per network processing unit (NPU). This solution offers a comprehensive compute-network-storage product for shared context memory, reducing access latency by 90% and increasing bandwidth to 40 TB/s, making it an attractive option for large-scale AI applications.
