Paper Title: Extending DPUs to Enable Software-Defined I/O (SDIO)
Paper Abstract: Software-defined I/O (SDIO) merges memory and storage in an effort to get full benefit from today's wide range of memory technologies and interconnects. It improves memory usage without demanding extra work from programmers, thus increasing TCO at the system level. Applications thus see the full advantage of such advances as SSDs, persistent memory, NVMe-oF, RoCE, and DRAM connected via the emerging CXL interface. Adding support for a flat memory hierarchy to DPUs can make them even more valuable in today's data-driven world. An on-board SDIO controller provides the required hardware, avoiding the need for an external unit. Future Arm cores can readily offer such features.
