Explore a technical conference presentation from the SNIA Compute+Memory+Storage Summit that introduces a novel host-assisted computational storage architecture for improving SSD performance through software-based compression. Learn how the HA-CSD system achieves efficient data compression without specialized hardware by leveraging host CPU capabilities and implementing smart compression strategies based on data hotness and compressibility. Discover how this solution, which can be deployed via simple firmware updates, delivers impressive bandwidth of 2.1GB/s and 5.2GB/s for reads and writes respectively while significantly improving RocksDB benchmark performance up to 5.7x compared to built-in compression methods. Understand the architectural decisions made to overcome the limited computing power of embedded SSD processors and optimize system-wide performance through offline compression and novel decompression techniques.
