Storage drive technology has made continuous improvements over the last decade, shifting the bottleneck of the data processing system from the storage drive to host/drive interconnection. To overcome this “data movement wall,” people have proposed in-storage computing (ISC) architectures which add the computing unit directly into the storage drive. Rather than moving data from drive to host, it offloads computation from host to drive, thereby alleviating the interconnection bottleneck. Though existing work shows the effectiveness of ISC under some specific workloads, they have not tackled two critical issues: 1) ISC is still at the early research stage, and there is no available ISC device on the market. Researchers lack an effective way to accurately explore the benefits of ISC under different applications and different system parameters (drive performance and interconnection performance). 2) What kinds of …
