National High Energy Physics Science Data Center

The National High Energy Physics Science Data Center (NHEPSDC) is a repository for high-energy physics. In 2019, it was designated as a scientific data center at the national level by the Ministry of Science and Technology of China (MOST). NHEPSDC is constructed and operated by the Institute of High Energy Physics (IHEP) of the Chinese Academy of Sciences (CAS). NHEPSDC consists of a main data center in Beijing, a branch center in Guangdong-Hong Kong-Macao Greater Bay Area, and a branch center in Huairou District of Beijing. The mission of NHEPSDC is to provide the services of data collection, archiving, long-term preservation, access and sharing, software tools, and data analysis. The services of NHEPSDC are mainly for high-energy physics and related scientific research activities. The data collected can be roughly divided into the following two categories: one is the raw data from large scientific facilities, and the other is data generated from general scientific and technological projects (usually supported by government funding), hereafter referred to as generic data. More than 70 people work in NHEPSDC now, with 18 in high-energy physics, 17 in computer science, 15 in software engineering, 20 in data management and some other operation engineers. NHEPSDC is equipped with a hierarchical storage system, high-performance computing power, high bandwidth domestic and international network links, and a professional service support system. In the past three years, the average data increment is about 10 PB per year. By integrating data resources with the IT environment, a state-of-art data process platform is provided to users for scientific research, the volume of data accessed every year is more than 400 PB with more than 10 million visits.

国家高能物理科学数据中心（NHEPSDC）是高能物理领域的数据存储库。2019年，经中国科学技术部（MOST）批准，该中心被认定为国家级科学数据中心。NHEPSDC由中国科学院高能物理研究所（IHEP）构建与运营。该中心包括位于北京的主数据中心、位于粤港澳大湾区分支中心和位于北京怀柔区的分支中心。NHEPSDC的使命是提供数据收集、存档、长期保存、访问与共享、软件工具以及数据分析等服务。NHEPSDC的服务主要面向高能物理及相关科学研究活动。收集的数据大致可分为两大类：一类是大型科学设施产生的原始数据，另一类是由一般科学技术项目（通常由政府资金支持）产生的数据，以下简称为通用数据。目前，NHEPSDC拥有超过70名员工，其中高能物理领域18人，计算机科学17人，软件工程15人，数据管理20人，以及其他运营工程师。NHEPSDC配备了分层存储系统、高性能计算能力、高带宽国内外网络连接以及专业的服务支持系统。在过去三年中，平均每年数据增量约为10 PB。通过整合数据资源与信息技术环境，为用户提供了一流的数据处理平台，每年访问的数据量超过400 PB，访问次数超过1000万次。
