Abstract: A storage system is the core of a computer, and plays an important role in the sustainable development of emerging strategic industries, such as artificial intelligence, big data, cloud computing, and the Internet of Things. Storage stack access is a major factor restricting the performance of data-intensive systems because of the increasing performance of processors and network devices. Recently, new storage devices have attracted wide attention due to their ability to break the “memory wall.” These devices include block-addressable flash memory, byte-addressable non-volatile random access memory (NVRAM), in-memory computing devices, and large-capacity optical storage. Continuous innovation in algorithms, software designs, and hardware is necessary to build large-scale storage systems with high throughput, low access latency, and high data reliability. It can address challenges in building larger-scale and higher-performance systems with more complex structures. Further, it can boost the experience in building and applying relevant systems and accelerate developing the big data processing.

存储系统是计算机的核心，在人工智能、大数据、云计算和物联网等新兴战略产业的可持续发展中起着重要作用。随着处理器和网络设备性能不断提高，存储软件栈成为限制数据密集型系统性能的主要因素。近年来，新型存储设备因其打破"内存墙"的能力而受到广泛关注。这些设备包括支持块寻址的闪存设备、支持字节寻址的非易失性存储器、存算一体化设备以及大容量光存储。构建高吞量、低延迟和高可靠性的大规模存储系统，需要对算法、软件设计和硬件的持续创新。这些创新可以应对大规模、高性能复杂结构系统构建中存在的挑战，还可以增加相关系统的构建和应用经验，加快大数据处理系统的开发速度。
研究人员一直致力于解决"内存墙"问题，并改进相关软硬件生态系统，从而在新型存储系统设计和应用方面取得很大进展，包括但不限于以下方面：
1. 不断推出和优化新型存储设备，例如开放通道固态盘、可字节寻址的非易失性存储器以及存算一体化设备。此外，陆续推出模拟器、仿真器和软件定义设备开发平台，促进了新型存储设备的设计和优化。
2. 现有存储软件系统最初为硬盘或传统固态硬盘而设计，不能充分发挥新型存储设备性能潜力。针对新型存储设备，设计了许多新型文件系统、存储管理软件、非关系型数据库以及关键组件。
3. 利用新型存储设备加速应用求解（如组合优化问题）和提升传统存储系统（如基于机械硬盘的纠删码存储）性能。
在此背景下，《信息与电子工程前沿（英文）》期刊组织了本期"新型存储系统设计与应用"专题。专题涵盖针对新型存储设备的辅助设计工具、各种存储软件、方法与相关应用，以及对新型存储系统前沿进展和未来研究方向的综述。经严格评审，选入7篇论文，包括1篇综述和6篇研究。
