Understanding CXL Part 2: System Networking and Memory Ecosystem

📋 Summary: Compute Express Link (CXL) has evolved from a direct CPU-to-memory expansion interface into a broader system-level interconnect technology. CXL 1.1 focused on single-host memory expansion, CXL 2.0 introduced switching and memory pooling, while CXL 3.x expands the architecture toward multi-host coherency and large-scale fabric networking. This article examines that evolution, the CXL product ecosystem, memory-vendor strategies, controller and switch silicon, and the practical limitations of CXL deployment.
