摘　　要：人机物融合泛在计算的新场景和新模式,需要新型的操作系统,即泛在操作系统.存储管理作为泛在操作系统的一项核心功能,设计轻量化、高性能和动态可适配的存储系统是推进泛在操作系统发展的必要举措.然而,对于“端(终端设备)-边(边缘端)-云(云端)”泛在场景中普遍存在的结构化数据,传统存储解决方案存在I/O放大严重、系统体量过大和软件栈冗余等问题,难以满足泛在应用的需求.为此,本文从系统全栈的角度进行原创性探索,提出原生表存储系统.本文首先回顾了计算机系统的发展历史;之后分析泛在计算时代的新需求,总结出泛在操作系统的基本形态,并介绍最新研究成果;然后剖析了现有结构化存储方案在“端-边-云”场景下面临的挑战;进一步提出面向泛在操作系统的原生表存储系统,并从端侧和边/云侧两个场景深入分析其架构优势.最后,总结全文并展望未来发展趋势.The emerging scenarios and paradigms of ubiquitous computing in the era of human-cyberphysical fusion demand novel operating systems,namely,ubiquitous operating systems.As storage management constitutes a core function of ubiquitous operating systems,designing lightweight,high-performance,and dynamically adaptable storage systems is an essential initiative in advancing the development of ubiquitous operating systems.However,in the ubiquitous“end-edge-cloud”scenarios,structured data is widespread,and traditional storage solutions face significant challenges such as severe I/O amplification,excessive size of integrated systems,and redundant software stacks,making it difficult to meet the demands of ubiquitous applications.To address these challenges,this paper conducts original research from a holistic system perspective and proposes a native table storage system.The paper begins by reviewing the historical evolution of computer systems.Subsequently,it analyzes the emerging requirements in the era of ubiquitous computing,outlines the fundamental characteristics of ubiquitous operating systems,and presents the latest research.It then delves into the challenges faced by existing structured storage solutions in the“end-edge-cloud”scenarios.Furthermore,it proposes a native table storage system for ubiquitous operating systems and provides an in-depth analysis of its architectural advantages in“end-edge-cloud”scenarios.Finally,we summarize the paper and offer insights into future development trends.
