To sustain the rapid growth of AI, cloud computing, and high-performance workloads, datacenters need memory solutions that balance speed, capacity, and cost, making memory tiering a crucial innovation. Wolley introduces an NVMe-oC powered memory tiering solution that seamlessly unifies DRAM, HDM (CXL device memory), and SSD into a single, intelligent memory space, delivering unprecedented efficiency without requiring any modifications to user applications. By leveraging NVMe-oC, which combines CXL device memory with SSD, our approach enables efficient data migration across tiers. A software policy dynamically detects data hotness, which ensure critical workloads benefit from high-speed DRAM, while less frequently accessed data is intelligently allocated to SSD, with HDM serving as an ultra-fast intermediate buffer. Our transparent, automated tiering mechanism boosts performance, reduces data movement latency, maximizes resource utilization, lowers TCO, and makes it a game-changer for large-scale datacenter efficiency.
