Overcoming the Memory Wall with CXL-Enabled SSD
summary
Study builds a physical memory tracer and a trace-driven simulator to model CXL-enabled SSDs and integrates a DRAM cache, MSHR and several prefetchers to address granularity mismatch, repeated flash reads and high latency. Evaluation on real-world traces reports 68–91% of requests served within one microsecond and an estimated device lifetime of at least 3.1 years for the worst-case workload. Results show prefetch accuracy and cache pollution drive wins or losses and virtual-to-physical translation needs kernel hints to help the device.
