Storage Developer Conference

All flash arrays incorporate a number of data reduction techniques to increase effective capacity and reduce overall storage costs. Compression and deduplication are two commonly employed techniques, each with multiple different strategies for implementation. Because compression and data reduction are only part of a greater data reduction strategy, one must also understand their codependent interactions with the rest of a storage system. This talk presents a structured overview of multiple different compression and deduplication technologies. The basics of each technique are presented alongside their benefits, drawbacks and impact on overall system design. This talk then augments that understanding by applying these various techniques to a sample real-world workload, demonstrating the impact of these decisions in practice.
