INSIDER: Designing In-Storage Computing System for Emerging High-Performance Drive
summary
INSIDER places an FPGA-based reconfigurable drive controller inside the drive, implements a separate control plane (permission checks, per-drive scheduling offloaded partially to hardware), and exposes computation as a virtual file abstraction with POSIX-like APIs so existing host code needs only tens of lines changed while drive kernels are hundreds of lines. A PCIe prototype saturates internal drive bandwidth, uses FPGA partial reconfiguration for multi‑tenant partitions, and reports 12X average speedup, 31X accelerator cost efficiency versus ARM-based ISC.
