As we embark on a new era of storage performance, the limitations of monolithic OS designs are beginning to show. New memory technologies (for example, 3D XPoint technology) are driving multi-GB/s throughput and access latencies at sub-microsecond scales. As the performance of these devices approaches the realms of DRAM, the overhead incurred by legacy IO stacks increasingly dominates.

Key Insights


To address this concern, momentum is gathering around new ecosystems that enable effective construction of tailored and domain-specific IO architectures. These ecosystems rely on bringing both device control and data planes into user space, so that they can be readily modified and intensely optimized without jeopardizing system stability.
