This presentation explores innovative solutions to enhance the data processing capabilities of the CMS Level-1 Scouting System. With the High Luminosity LHC upgrade and the increase in data volumes, advanced techniques for trigger events selection and data processing are required. For this reason, we are evaluating Compute Express Link (CXL) enabled devices, focusing on latency and bandwidth measurements and addressing memory management challenges. By combining CXL cache coherency and the Fabric-attached memory file system (Famfs), we can provide disaggregated shared files and multi-host memory management. The integration of these technologies is ongoing within the SCDAQ software for demonstration purposes..
