A Fast and Flexible Hardware-based Virtualization Mechanism for Computational...
summary
An FPGA card called FCSV-Engine implements hardware‑assisted virtualization for both the computation and storage blocks, extends NVMe with a new command format, and uses PCIe peer‑to‑peer routing plus an operator renaming table and shared operator pool to dynamically map work. A prototype with 8 operator slots sharing operators among four VMs proves the design, showing about 2× throughput over software virtualization and a 40% gain with peer‑to‑peer plus significantly fewer QoS violations; partial reconfiguration further reduces hotspots.
