Disk-based smart storage represents processor-embedded active I/O devices that are equipped with a dedicated network interface controller and on-disk storage (memory and disk). Today's I/O-intensive workloads require architectures whose performance scales with increasing storage capacity. The advent of switch-based, low-latency and high-bandwidth network protocols, such as Virtual Interface Architecture and InfiniBand, promises to improve both performance and scalability beyond current state-of-the-art I/O interconnect topologies. This paper evaluates a disk-based distributed smart storage architecture composed of fully distributed processor-embedded disks that are interconnected by a high-performance switched network, and investigates the performance of the proposed processing model on different storage interconnects with representative workloads, including TPC-H queries, association rules mining, high-dimensional data clustering, and two-dimensional fast Fourier transform (FFT).
