Digitalization across society is expected to produce a massive amount of data, leading to the introduction of faster network interconnects. In addition, many Internet services require high throughput and low latency. However, having only faster links does not guarantee throughput or low latency. Therefore, it is essential to perform holistic system optimization to fully take advantage of the faster links to provide high-performance services. Intel Data Direct I/O (DDIO) is a recent technology that was introduced to facilitate the deployment of high-performance services based on fast interconnects. We evaluated the effectiveness of DDIO for multi-hundred-gigabit networks. This paper briefly discusses our findings on DDIO, which show the necessity of optimizing/adapting it to address the challenges of multi-hundred-gigabit-per-second links.
