Compute Express Link (CXL) has risen as a promising interconnect technology that enables seamless high-speed, low-latency communication between host processors and various peripheral devices, making it attractive for memory-intensive applications. In this talk, we'll evaluate the performance characteristics of CXL memory in real-world environments using ASIC-based CXL memory. We then present our learnings from microbenchmarks, explore the potential use cases and evaluate their benefits from using CXL memory. Based on our comprehensive evaluations, we share our insights of how we may better utilize CXL memory to optimize the performance and cost of data center applications, as well as our vision for next-gen memory architecture leveraging new capabilities from CXL 2.0/3.x.
