Understanding CXL Technology: Memory Expansion and Storage Integration in Modern Data Centers

Explore a 41-minute keynote presentation that delves into the significance of Compute Express Link (CXL) technology for the storage community, delivered by Dr. Yang Seok Ki from Samsung Electronics. Learn about the evolving landscape of data center architectures driven by exponential growth in data volume and traffic, focusing on the disaggregation and composability of computing resources. Gain insights into CXL's role as a key enabling technology for high-speed, low-latency interconnects with memory cache coherency between various computing components. Discover Samsung's CXL memory technologies, including memory expanders and memory semantic SSDs, while understanding the technical aspects of memory interfaces, cache coherence, access latency, and memory capacity challenges. Master the concepts of hardware abstraction, basic software implementation for memory expansion, and the convergence of memory expansion fabric into CXL. Examine the economic considerations of memory emulation using storage, extended memory subsystem architectures, and the emerging field of computational storage/memory devices.
