The rapid improvement of overall $/Gbyte has driven the high performance All-Flash Array to be increasingly adopted in both enterprises and cloud datacenters. Besides the raw NAND density scaling with continued semiconductor process improvement, data reduction techniques have and will play a crucial role in further reducing the overall effective cost of All-Flash Array. One of the key data reduction techniques is compression. Compression can be performed both inline and offline. In fact, the best All-Flash Arrays often do both: fast inline compression at a lower compression ratio, and slower, opportunistic offline deep compression at significantly higher compression ratio. However, with the rapid growth of both capacity and sustained throughput due to the consolidation of workloads on a shared All-Flash Array platform, a growing percentage of the data never gets the opportunity for deep compression. There is a deceptively simple solution: Inline Deep Compression with the additional benefits of reduced flash w
