CXL Memory Module - Memory Pooling (CMM-MP) introduces a novel memory pooling architecture to meet the unique requirements of emerging memory-intensive workloads. This industry-first, purpose-built memory-pooling device combines the benefits of Compute Express Link (CXL) with the scalability and cost advantages of Ethernet. Multiple CMM-MP devices together provide a flexible, composable, and disaggregated memory expansion solution. The CMM-MP enables 100s of TB capacity for GPU/CPU applications without modifications. The memory pool is exposed as a large-capacity logical aggregate memory, with all pool discovery, composition, and backend network datapath tasks fully offloaded to the device. CMM-MP supports both memory pooling and sharing usage modes. It provides an application latency of 2.7 us and up to 23 GB/s of memory throughput. Our evaluations demonstrate that CMM-MP significantly outperforms RDMA-based solutions in latency and throughput. We also evaluated real-world use cases of Valkey+YCSB and DiskANN using CMM-MP.
