The Past and Future of CXL with Allyson Klein | Utilizing Tech 4×18

CXL grew out of a long history of Intel platform technology and promises to revolutionize this platform. This episode of Utilizing CXL features Allyson Klein of TechArena, who shares her vision for the future of disaggregated servers with Craig Rodgers and Stephen Foskett. The foundation for CXL was laid with coherent interconnects and fabrics in previous decades, and the concept of tiered memory draws heavily on the history of Intel and Micron 3D XPoint and Optane Persistent Memory. As was the case for virtualization, CXL has an initial value proposition and a revolutionary future. CXL opens up virtually unlimited memory, pools of processors and offload engines, and unprecedented flexibility. Ultimately CXL will allow us to deliver compute resources that are truly balanced and matched to the needs of each workload. We also discussed UCIe, which promises to enable mix and match chiplets within future processors in a way that is compatible with CXL.
