“中国天眼”位于贵州平塘县克度镇深山里的“大窝凼”，坐落在几百万年前形成的喀斯特丘陵中，从山顶向下看，就像一口“大锅”，其口径达到500米；其球状反射面相当于30个足球场，从底部到顶部垂直高度138米，超过世界上最大的胡夫金字塔。

作为涉及到天文、力学、材料、机械、无线电、IT等多个领域的科技基础设施，“中国天眼”不仅是中国科学家砥砺奋斗二十余载的成果，更是中国在科技基础设施领域的一次突破。国家发改委近日明确指出新型基础设施的范围，其中创新基础设施是指支撑科学研究、技术开发、产品研制的具有公益属性的基础设施，像“中国天眼”这种重大科技基础设无疑是新基建的典型代表。
自2020年1月11日正式投入运营以来，“中国天眼”已发现132颗优质的脉冲星候选体，其中有93颗已被确认为新发现的脉冲星。中国天眼项目科学家李菂表示，“FAST是目前世界上灵敏度最高的射电望远镜，是美国阿雷西博望远镜的2.5倍以上，巡天速度是阿雷西博的10倍。FAST预计对国际同类设备至少可以保持二十年以上的领先地位。”
而随着时间推移和科研任务的深入，“中国天眼”不断产生海量数据，对存储容量、性能的需求也在不断增长。为此，国家天文台近年来持续推进FAST科研数据中心建设。在最近一次升级中，国家天文台携手浪潮存储，以分布式存储AS13000G5构建30PB可用容量、50GB带宽的天文大数据平台，为中国天眼的天文大数据存储、处理和实时分析提供有力支撑。
此次，浪潮存储的作用不仅是让中国天眼“装得下”数据，更成为天文大数据分析的“加速器”，在宇宙未知领域探索中发挥积极影响。在中国天眼项目中，浪潮存储独创性地在一套分布式存储平台里部署了面向HPC和AI应用的H节点和面向高密度场景的M60两种节点，实现冷热数据分级存储，高性能节点提升天文大数据处理和分析的效率；高密度节点实现单节点容量接近1PB，提供海量存储空间；并且，不同层级存储之间能够根据天文业务需求实现数据自由流动，带来更加快捷的科研体验。
中国天眼数据中心专家表示，“这次和浪潮存储的合作让我们印象深刻，浪潮存储不仅有硬核产品，还有专业生产、交付团队。即使在疫情这样的特殊情况下，浪潮存储仍然能够推进项目提前上线，这超出了我们的预期”。
未来，随着“中国天眼”观测、科研、数据三大完整科学研究框架加速建成，我国的天文科研实力必然会再上一个台阶，在浩瀚宇宙中展现出中国科研的实力。";}, 1621686945, 1716074217
